How much calcium should I take?

The shell of one medium-sized egg will yield approximately 1 tsp. powder, which is equal to 700-800 mg of calcium. The daily dose for most people is 400 mg, i.e. 1/2 tsp each in a day. For pregnant women, the dose is doubled, for children it is halved. It is advisable to divide the intake of the powder into 2 stages of 1/4 tsp each, because the body absorbs no more than 500 mg at a time.

But there are no standards for the use of calcium. If you drink a glass of raw milk or consume canned sardines, soup or bone broth, the dose can be significantly lower. Depending on the food eaten during the day, adjust the dose of additional calcium. Perhaps some day it may not be needed at all.

When to take calcium?

For better absorption of egg powder by the body, you need to consume calcium in the morning with food. Calcium is best absorbed with vitamins A and D. They are found in liver, coconut and butter, fermented cod oil and other products. Don't forget about vitamin C, it also improves calcium absorption.

Ingredients:

Raw eggs – any quantity

Step-by-step preparation of eggshell powder:

1. They say that the healthiest shells are from birds that live in the wild, but in our modern life we most often use chicken shells. Therefore, take raw chicken eggs, wash them well with warm running water and scrub with a steel brush to remove all dirt. Carefully break the egg and drain the contents: white and yolk.

2. Wash the shells under running water again. WITH inside remove the thin white film. It is very easy to remove. It will be enough just to pry it, pull it and it will come off. Lay out the shells and leave to dry completely for about 3 hours. You can dry it in the sun, fresh air, tray, towel.

Note: if the eggs are purchased and not homemade, then dip the shells in boiling water for a few minutes and only then dry them. This way you will protect yourself from salmonella and kill bacteria.

3. In a similar way, collect shells from at least 10 eggs.

4. When you have the required amount, take a coffee grinder and place part of the shell into it. You can break it a little into smaller pieces.

An acute lack of calcium negatively affects the functioning of the entire body, so people often ask pharmacies for vitamin complexes containing it. Why take eggshells is a question many people may ask. After all, in pharmacies you can find anything that contains calcium.

But in reality, many pharmaceutical drugs turn out to be ineffective and are eliminated by the body without bringing any benefit. In addition, the cost of vitamin complexes may be too high. Fortunately, there are cheaper and effective remedy, which is perfectly absorbed by the body, is eggshell.

Since ancient times, people have compensated for calcium deficiency with its help. Old healing books contain many recipes that use this product. These books advise eating eggs without internal contents. They are recommended to be eaten immediately after waking up early in the morning.

They also advise adding them to a variety of foods, especially high-fat foods. Doctors find this method also effective. They recommend taking eggshell powder to women during childbearing and breastfeeding, people suffering from osteoporosis and athletes during increased physical activity. So why is it recommended to use it, what are the benefits of eggshells, let’s try to figure it out.

What benefits are contained in eggshells?

The shell acts as a protective shell, preventing the internal contents of the egg from spilling out. Nature has endowed this thing with strength on the outside and fragility on the inside so that the chicken can hatch when the time comes to hatch. The ancestors could not ignore this feature and attached special significance to it. Egg shells were used in various rituals in the preparation of various potions.

Today people do not believe in such obscurantism, but this does not reduce the usefulness of eggshells. Let's consider what useful things this protective shell contains, what is the composition and benefits of egg shells:

It contains calcium carbonate, which is best absorbed by the body. In addition to beneficial calcium, you will find many other beneficial substances - amino acids, vitamins and minerals;
Eggshell calcium helps strengthen bone tissue, teeth, and human muscles. Therefore, it is useful to take it for people suffering from osteoporosis, arthrosis and other diseases. It helps quickly restore bones after injuries;
When eating eggshells, there are no side effects observed as with some other artificial substitutes. Therefore, women expecting the birth of a child can take it, replenishing calcium deficiency, without fear for the health of the unborn baby. If young children suffer from calcium deficiency, then they should definitely be given eggshells. This calcium will be beneficial to them and promote bone growth;
Calcium is of great importance for the full functioning of the body, and if the body lacks it, then a person’s metabolism is disrupted, hair falls out, nails break, herpes appears on the lips, and the immune system works poorly. Children may develop rickets, curvature of the spine, and anemia. No pharmaceutical drug can replace eggshells as a source of calcium, so it is essential to eat them.

Scientific research confirms the effectiveness of this product. In the near future, Hungarian scientists learned about the enormous benefits of this product for the human body. But they did not publish the results of their research to the masses. A little later, Belgian, Dutch and American researchers took up this issue and they received the same result as the Hungarian scientists. The high effectiveness of eggshells has been proven in clinical studies.

But most interesting is the fact that many animals, such as dogs, squirrels, ferrets, etc., during the period of bearing offspring, eat eggs along with the shell. They intuitively choose what is good for their body. Therefore, it is simply recommended for a person to consume calcium from eggshells, especially since the preparation of this product is easy. You need to do this in order to stay healthy. The shell contains the same substances as those found in human bones and teeth, so the body happily accepts it and easily processes it.

How to properly eat eggshells

When we say that it is extremely useful to consume this product, we do not mean that you need to pick it up and chew it. Such an action will only cause harm, especially the teeth will suffer. Let's look at how to take calcium from eggshells so that it is better absorbed by the body. To do this, you need to learn how to cook eggshells.

Eggshells need to be processed and cooked. If you crush eggshells, this will not change its chemical composition, but will make this product more edible. Let's look at how to properly prepare this product.

You can take any eggs with white or brown pigmentation, either of them has the same calcium content. You can also make a vitamin supplement from quail egg shells, but it is much more difficult. Therefore, take better chicken eggs.

The surface of eggs can harbor a lot of pathogenic bacteria, so clean it with soap and water. For more thorough processing, they can be sterilized by placing them in boiling water for 5 minutes. Chemical composition the shell will not change in any way. But if you cook them longer, the calcium will lose some of its beneficial properties.

Do not remove the white film from the shell, as it also contains useful material. Before you start crushing the shells, you need to dry them thoroughly. You can spread it out in the fresh air or put it in a slightly warm oven. Break the shell as you wish into small pieces.

Next, you will need to grind the shells to a powdery consistency. You can do this in any way convenient for you - using a coffee grinder, mortar, blender, etc. The less you chop, the more convenient it will be to take.

Place the shell powder in a glass container and leave it where no water can penetrate. You can put the powder into gelatin capsules, which can be purchased at the pharmacy, or empty them of their contents.

Crush one egg and you will get one teaspoon of powder. This means that your body will receive 700 mg of calcium. Larger goose or ostrich eggs contain more calcium, but chicken eggs are better.

Egg powder dosage

If you are a healthy person and eat enough calcium-containing foods, limit yourself to 400 mg of powdered eggs per day. This will be enough for your body to fully receive calcium from eggshells. For children, it is necessary to reduce the dose by half, to 200 mg.

For those people who have problems with the body due to a lack of calcium, the dose is calculated individually.

When the substance responsible for the strength of the skeletal system in the body is not enough, then eggshells as a source of calcium are an irreplaceable thing. You need to take a small amount daily - one teaspoon of eggshell powder will be enough. This product can be added to any dish. You can even consume it without food by adding a little lemon juice. Vitamin C is an excellent companion for calcium, increasing its absorption.
People with minor bone fractures can consume eggshells in the same dosage – 1 teaspoon per day. This product should be added to your daily drink, no matter what you prefer - tea, milk, juice, etc., add egg powder to it. Divide one teaspoon into three doses and consume in the morning, at lunch, and in the evening. For children under 14 years of age, reduce this dose by a third. It is necessary to take egg powder in this quantity until the bones grow together.
If a person suffers from osteoporosis, then crushed eggshells are also indicated for him. For such people, it will be useful to undergo a course of therapy that lasts up to 30 days. Egg powder is taken 30 minutes after dinner in the amount of half a teaspoon. It is necessary to dissolve it in half a glass of milk or kefir.

What diseases does eggshell treat?

Diathesis. For exudative-catarrhal diathesis, it is necessary to give the powder 3 times a day, a quarter of one teaspoon. Improvements will come about thirty days after taking this.
Skin diseases - hives, prickly heat, etc. To cure skin problems, an infusion of eggshells is prepared. To do this, take the eggshells of fifteen eggs, put them in boiling water and infuse for 24 hours. This infusion can then be added to the bath for children suffering from hives. This infusion is added to food or dishes are prepared based on it.
Asthma. To reduce the symptoms of asthma, start consuming one gram of egg powder. Reduce the dose daily to 0.1 grams, then increase again. The course of treatment is 1 month. Then take a break for one month and repeat the course again.
Gastritis. In order to cure gastritis, it is necessary to prepare egg powder in a special way. You need to fry it in a frying pan until the egg shells darken a little. Then you need to take it on an empty stomach. One teaspoon will be enough. After a week, it will neutralize the acid and the stomach pain will decrease. For heartburn, powdered eggs are more effective than the baking soda that people usually take. Just 2.5 tablespoons with one glass of water and the unpleasant feeling in your stomach will go away without a trace.
Burns. Eggshell powder helps open and quickly heal burns.

Damage to eggshells

People with cancer are prohibited from taking eggshells.

The surface of the egg contains bacteria that cause salmonellosis. That is why it needs to be well processed before use.

Excess calcium is no less important for the functioning of the body than its deficiency. If you have hypercalcemia, it is not recommended to take eggshells.

If people knew exactly what they were missing, then calcium would take one of the leading positions in this anti-hit parade. The lack of calcium can be compensated for by taking pharmaceutical medications, but this is not always possible. Firstly, calcium is not absorbed in all forms. Secondly, the prices of high-quality calcium supplements are so high that instead of one jar of tablets it is better to buy food for a week. And it really is better! For example, combine good things with good things and take eggshells as a source of calcium.

Calcium in eggshells is contained in the natural state that is best absorbed by the human body. You can take calcium gluconate, combine calcium intake with vitamins and other minerals, follow a diet - but it is much easier to take calcium from eggshells, as our grandparents did. Even today, doctors advise taking eggshells for osteoporosis, pregnancy and simply increased stress.

Why take eggshells? Composition and benefits of egg shells
The shell of an egg is its “armor”, protecting its precious contents from external threats. The infinite wisdom of nature made the shell strong on the outside and fragile on the inside, so that right time The chicken hatched from the egg without any problems. This apparent fragility and genuine resilience was noticed by our distant ancestors, who endowed eggs with sacred meaning and tried to borrow its power by taking eggshells with food, adding them to drinks and potions. Today, thanks to the achievements of science, one could easily do without this “obscurantism” and take pharmaceutical calcium preparations. Nevertheless, modern people continue to take eggshells. Why?
How to take calcium from eggshells? Cooking eggshells
No one wants to chew on eggshells - and if they suddenly tried, it would do more harm to their teeth than good. In order for calcium to be absorbed and benefit from the inside, it must be taken in prepared form. Therefore, eggshells are crushed and powder is prepared from it, which does not change chemical properties, but makes it suitable for consumption if you prepare the powder from the shell correctly:
From the shell of one chicken egg of grade 1-2 you get about 1 teaspoon of powder containing at least 700 mg of calcium. Of course, the yield of powder from larger duck and goose eggs is different, not to mention the giant ostrich egg. But it’s better to limit yourself to chicken and/or quail eggs, because salmonella is much more common on all others.

How to take eggshells with food?
The dosage and rules for taking eggshells are simple, but differ slightly depending on the purpose. The average adult needs about 400 mg of calcium per day, provided they have sources of calcium other than eggshells (dairy products, fish, broths, etc.). For children from 1 year to school, half of this dose is enough, that is, 200 mg of calcium per day. Eating disorders and/or problems in the body require individual approach. Here are the most common indications and instructions for using calcium eggshell powder:
For pregnant women, eggshells are prescribed by a doctor - it is better not to experiment and follow his instructions exactly. Moreover, among the recommendations for taking eggshells you can find not only rational, but also very exotic recipes. For example, the authors of old medical books strongly advise using the shell of the exact egg from which the chicken has just hatched.

Although there are bright thoughts in these books. For example, information that it is advisable to take eggshells in the morning, if there are no other specific instructions, and combine them in the diet with butter, cod liver, coconut and/or other vegetable fats. The latest laboratory studies have confirmed and explained these rules: it’s all about vitamins D and A, which improve the metabolism of calcium in the body. All this once again proves how closely the methods of traditional medicine are intertwined with modern science, and that eggshells as a source of calcium are not in vain. Take eggshells correctly and stay healthy!

Huge amounts of eggshells are thrown into waste every day. Unfortunately, not everyone knows about its long-term use in folk medicine. Let's talk about how to take this product correctly in order to benefit from it, and whether harm is possible from procedures with it.

Composition and properties of eggshells

Eggshells are a valuable source of an essential mineral that a person needs throughout life - it consists of 90% calcium carbonate. A deficiency of this substance leads to the development of more than 150 diseases, including osteoporosis, rickets, caries and arthritis. The remaining 10% comes from other micro- and macroelements: fluorine, phosphorus, copper, iron, zinc - a total of 27 types, including rare ones (molybdenum and silicon).

Even children from six months of age can replenish calcium reserves with eggshell powder. In the fight against allergies, the product acts as an absorbent, reducing the body's sensitivity. The shell eliminates the symptoms of heartburn and alleviates diarrhea. Calcium water prepared from the product helps alkalize the body. Consumption of shells by older people and women during menopause helps prevent osteoporosis. Thanks to high content The hyaluronic acid product is used in face masks to help combat the appearance of wrinkles. Zinc contained in the empty shell of eggs fights acne and its consequences, disinfecting and whitening the skin. A scrub based on shell powder will be useful for the body.

Egg film (shell membrane) also found its use in folk medicine. It is rich in calcium and magnesium, as well as protein beneficial to the body, which allows it to be used for the treatment of joints in the pharmaceutical industry. In addition, having a bactericidal effect, the film promotes the rapid regeneration of damaged skin.

Methods of using eggshells in folk medicine

Proper preparation of powder

It is worth noting that we are talking about the shell of a chicken egg. It is not recommended to use the product from other birds (ducks or geese) due to the high risk of salmonella infection. Quail eggs There is no threat of infection, but practical preparation of powder from the shell is difficult due to its tiny size.

It is best to use shells from the eggs of country birds, in this case you can be sure that it does not contain unnecessary chemical impurities that may be found in a store-bought product. The color of the shell does not matter, since it is associated only with the color of the laying hen, which does not affect its chemical composition.

The powder preparation algorithm is as follows:

The egg is washed twice with soap and a brush in hot water.
They break it, remove the contents and rinse the shells again (at this moment it is most convenient to remove the film).
Boil the raw materials for 5 minutes in water and dry at room temperature.
Grind the shells using a coffee grinder to a powder.
Store the product in glass jar with a tight lid, avoiding light.

There is an opinion that when in contact with metal, part beneficial properties the shell disappears. To preserve them, you should use a porcelain mortar and pestle or a hand mill when grinding the product. In this case, it is better to pre-heat the eggshells in the oven at a temperature of 50 degrees until they become brittle.

Preparation of medicinal products

Reception for the prevention of calcium deficiency (including in the elderly), for rickets, and for tooth loss

In order to restore calcium reserves in the body, it is necessary to consume shell powder daily in a dosage that will depend on age:

for infants from six months to one year - a pinch (on the tip of a knife) once a day;
for children from one to two years old - a couple of pinches per day;
for children from two to seven - half a teaspoon per day;
Teenagers and adults are supposed to eat a teaspoon of powdered eggs, dividing the intake into two times.

For better absorption, you need to add a couple of drops of natural lemon juice to the eggshell powder. It converts calcium carbonate into the form of calcium citrate, thereby increasing the penetration of the important mineral into the blood by 11 times.

Eggshells should be consumed before or during meals with a small amount of water. The course lasts 2–3 months; in case of serious deficiency, the use of the powder should be extended to 6 months.

Eggshell infusion (or calcium water) is another option for normalizing calcium balance. The preparation method is simple: per liter of water you need to take 1 teaspoon of the crushed product and leave the composition for at least five hours, after which it should be strained. Drink healthy water possible during the day until the deficiency is eliminated.

A restorative agent indicated for bone fractures to strengthen them.

For bone fractures, the body requires a dosage of calcium that exceeds the preventive norm. It is recommended to consume 3 teaspoons of powder three times a day, adding lemon juice or stirring powdered eggs in water. In the latter case, the solution must be drunk until sediment appears. The course of treatment is 3–6 months.

Use to prevent osteoporosis (according to the method of Dr. I.P. Neumyvakin)

The intake of natural calcium must be divided into two times; the recommended daily dosage is a teaspoon of powder slaked with lemon juice. You need to use the shell for at least a month, and repeat the course several times a year. To prevent the mineral from being washed out, Dr. I.P. Neumyvakin recommends limiting the consumption of strong tea, coffee, cocoa products and alcohol and introducing vitamin D into the diet.

Compress with kefir for reactive arthritis

Take warm kefir and eggshell powder in a 1:1 ratio, mix the ingredients until a paste is obtained, apply to a cloth and apply to the sore joint. To enhance the thermal effect, wrap the problem area with a compress. plastic film and wrap up woolen fabric. The course of treatment lasts 5–7 days, after which a break is taken for the same amount of time and therapy is resumed.

It is most effective to apply a compress before bed to get the maximum benefit from the procedure and avoid hypothermia of the joint.

Relieving allergies with slaked egg shells

The natural remedy is suitable for relieving children, including those suffering from egg intolerance, from allergic manifestations. Giving the powder to a child is not difficult: kids love to watch the product hiss when adding lemon juice. The dosage is similar to the preventive norm; the duration of taking eggshells is about six months.

Ground shells for heartburn symptoms

To eliminate heartburn, you need to take half a teaspoon of ground shells and drink water. This method is suitable for people suffering from high stomach acidity. If it is normal or reduced, it is recommended to extinguish the same amount of powder with lemon juice or diluted apple cider vinegar, adding 1 teaspoon of honey to the mixture. The drug is taken twice a day (before or after meals).

Composition with lemons for the treatment of bronchial asthma

Such a multicomponent composition for the treatment bronchial asthma Take 30 g three times a day before meals (half an hour before) until complete recovery.

Skin restoration using egg film

The egg film is applied to the affected areas of the skin - sun and thermal burns, splinters, cuts, boils, pimples - until completely dry. It is necessary to use the product several times until the problem disappears.

Home cosmetology recipes

Facial toner

By boiling egg shells in water for 12 hours, you can obtain precious hyaluronic acid - the more raw materials are added to the liquid, the greater the amount of this substance goes into the decoction. Strained water can be used independently (as a toner) or added to multi-component masks.

Hyaluronic applications for wrinkles

You need to make your own gauze masks for the face and neck area, having previously cut out holes for the lips and eyes, and then from time to time moisten one of the resulting napkins in a healing solution and place it on the face and neck for a quarter of an hour. Applications can be used three times a week.

You should not avoid the area around the eyes and lips; on the contrary, it will be useful to nourish these areas with hyaluronic acid.

Mask with banana and dairy products for dry skin

A ripe banana is mashed with a fork and mixed with hyaluronic water, cream and rich sour cream. Proportions of products are measured in tablespoons in the ratio 1:1.5:1.5. After this, half a glass of starch is added to the composition and the product is divided into equal parts: half a tablespoon of shell powder is added to the first, the second remains unchanged. A mask with eggshells is applied to a cleansed and moisturized face. When the layer dries, apply the second part of the composition (it is advisable to cover the skin with gauze during the procedure). The period of action of the product is half an hour, the procedure is carried out 2-3 times a week. This mask can be removed with water and a cotton swab.

Acne (and skin whitening) mixture

Eggshell powder is mixed with liquid honey in a 1:2 ratio. Add 1 tablespoon of salt and the juice of one lemon. The resulting paste will need to be applied to the face and covered with gauze. You need to leave the mask on for a little less than a quarter of an hour. As it dries, you need to periodically moisten the gauze with the mixture. The composition is washed off warm water. The frequency of use of this product is 2–3 times a week.

Multi-component body scrub

A body scrub can be made from eggshells with the addition of flour.

To prepare the scrub, the shells are ground in a coffee grinder. You should take one tablespoon of the following ingredients: egg shell powder, honey, flour (preferably rice), water and lemon juice. All components are mixed and applied to the body skin as a scrub once a week.

It is not recommended to use this product on facial skin due to the presence of coarse abrasive powder particles.

Shell with fish oil to strengthen hair and nails

For this purpose, you can consume eggshells in a prophylactic dosage, adding two capsules of fish oil per day. The recommended duration of the course is 30 days, it should be repeated twice a year.

Contraindications and possible harm

Despite the apparent safety of the natural product, eggshells should not be used internally:

with excess calcium in the body (hypercalcemia);
for acute manifestations of gastritis, cholelithiasis and urolithiasis, intestinal obstruction;
for arrhythmia;
infants up to six months.

The shells of large fractions should be chewed thoroughly to avoid injury to the stomach and esophagus from sharp edges. When used externally, avoid using coarse grinds to prevent skin cuts.

A natural and cheap source of calcium is calcium from eggshells. Combined with magnesium and vitamin D, Calcium from the shell is ideal for our body. The main advantages of such calcium are low levels of calcium in the blood and a high percentage of absorption. You can make calcium from eggshells at home.

Shell for homemade calcium

Daily dose from 400 to 2000 mg per day (nursing mothers). So much has been written and said about it, but the culture of consuming foods rich in calcium is at zero... “Drink, children, milk” - well, well, let’s drink 2 liters a day (this is the volume of the daily dose of calcium that will be absorbed taking into account losses ), and we'll get diarrhea and high cholesterol. Last years Studies, moreover, show that milk calcium is poorly absorbed (10%-30%). But what to do with the huge amount of milk protein, the processing of which consumes calcium from the body? What should those who are lactose intolerant do? For example, a billion Chinese?

The best source of calcium is plant foods. Calcium from a plant source is well absorbed and lacks side effects, unlike milk calcium.

Rating of products with calcium:

Soy. 100g - 258 mg of calcium with an ideal calcium-phosphorus ratio. Our cows, by the way, are fed rapeseed and soybeans (Ukrainian cows).
Cauliflower and broccoli.
All green parts of vegetables and herbs - parsley (245 mg), dill, tops, spinach.
Beet.
Bran, sesame, garlic and onion.
Almonds (260 mg)
Mineral water.

Milk and meat do not solve the problem of calcium deficiency. Vegans and vegetarians have made great progress in this matter - their bone tissue is healthier than that of meat-eaters. Salt, which removes calcium and magnesium from the body, also greatly spoils the picture. In turn, starch from vegetables helps calcium to be absorbed. Overall, we can eat our daily minimum amount of calcium if we try REALLY hard. But what if you need an additional source of calcium, for example, a nursing mother or child, or an athlete? Which calcium to choose- calcium gluconate, calcium hydroxide, aspartate, citrate? There is also coral calcium and this is not the end of the list.

Eggshells contain 27 microelements, which are very similar in structure to our teeth and bones. On the website of the National Center of Biotechnology there is a publication on the prevention and treatment of osteoporosis using eggshells (on English language). Homemade calcium supplement is very easy to make with your own hands.

How to make a calcium preparation from eggshells?

The shells of any poultry are suitable for us - quails, ducks, chickens, geese. It is advisable that the eggs come from free-range birds. The calcium content in the shell directly depends on what the chicken eats. Before breaking an egg, wash it thoroughly so that you don’t have to worry about washing the shell later. Collect shells from 10 eggs and store in the refrigerator.
When the required amount has been collected, rinse them in hot water; there is no need to remove the membrane. Now the shell needs to be disinfected.

There are at least 4 disinfection options:

Boiling
Microwave
Oven
Hydrogen peroxide

When boiling, some of the calcium is washed into the water (at least that’s what they say). You can water flowers with this water, and you can cook soups with it if you wish. Cook the shells for 3 minutes by throwing them into boiling water. I prefer the microwave option. There are serious studies showing that microwaves kill most “kitchen” bacteria within 2 minutes (more precisely, from 2 to 10 minutes), so you can dry the shells in the microwave without boiling and losing calcium. You can also dry and disinfect the shells in the oven - 200 degrees for 10 minutes. I read that some people wash the shells in hydrogen peroxide.

The shells must be completely dry before grinding. The first grinding can be done in a blender by loading the crushed shells into the bowl - just remember that they are in the bag. A finer grind should be achieved using a coffee grinder. The smaller the better. The powder should be stored in a tightly closed jar in a dark place.

How to prepare calcium citrate from carbonate

One heaped teaspoon contains about 1000 mg of calcium carbonate. Calcium carbonate is not suitable for us- if you take it in its pure form, it will be deposited in the form of kidney stones, spurs, and calcify blood vessels. Calcium citrate is suitable for us(by using citric acid) or calcium acetate(using vinegar). From calcium carbonate we can get both types of calcium.

Calcium Citrate and Acetate Recipe:

Pour 1 level teaspoon of ground shells (600-700 mg of calcium) into a glass.
Add a tablespoon apple cider vinegar(to get acetate) or juice of half a lemon (citrate). Mix until the mixture starts to bubble.
Let the mixture sit for a couple of hours, you can do it overnight, but do not let the reaction work for more than 12 hours. I have seen recommendations to take it immediately, without allowing the reaction to complete.
Add some water to the mixture, shake and drink. You can take it once, you can divide the dose into 2 or 3 times.

I found a video tutorial on making calcium citrate.

How is calcium absorbed?

To absorb calcium, magnesium and vitamin D are needed. With vitamin D, everything is simple - it is synthesized in the epidermis under the influence of ultraviolet radiation. Simply put, 15 minutes of walking in the sun (as Dr. Komarovsky says) and the deficiency is filled. However, both Americans and Russians, as well as Indians who get enough sun, have vitamin D deficiency.

Food sources of vitamin D: seaweed and seaweed, fish oil, butter (minimal), herring, yolk.

With magnesium, everything is much more complicated, but there are 2 excellent ways, about which there is a separate article with detailed instructions. Thus, having minimum expenses, we provide ourselves and our family with essential minerals.

Update 11/15. 2016

I continue to follow publications and news in this area and understand that not everything is so simple. The most recent independent studies demonstrate the inadequacy of women taking calcium + D3 as a preventive measure for osteoporosis during and after menopause. Osteoporosis is associated with hormonal levels, not a lack of minerals. On the contrary, calcium from drugs can calcify vascular fatty plaques and aggravate other problems.

Once again I am convinced of a simple truth - you need to eat as varied as possible, always eat different cereals (and not just pasta and rice), try mixing pumpkin, celery, kohlrabi in salads (just an example).

In a word, you need to make any appointments for yourself with great caution. Take care of your health and keep your mind cool!
