Myths and legends

How to understand that there is not enough calcium in the body?

Probably, any modern person, when asked “Why is calcium needed in the body?” will answer without hesitation: “For the bones.” To a large extent, this is true: almost the entire volume of calcium contained in the body is located in the bone tissues of skeletal structures, and the main processes of its absorption and processing are carried out there. However, it is needed not only “for the bones”. The role of calcium as a biochemical reagent is much broader and more important: this macroelement (not to be confused with microelements, the required concentration of which is orders of magnitude lower) is involved in the regulation of the processes of excitation-inhibition of the nervous system, desensitization and immune response (it is no coincidence that calcium salts are prescribed for allergic reactions), cellular nutrition, contractile activity of muscle fibers, peristalsis, differentiation of stem cells, secretion of enzymes and hormones, hair and tooth growth. Nutritional deficiency of calcium, as well as deficiency of other key macro- and microelements (for example, iodine, magnesium, potassium, etc.) at this stage of development of civilization is becoming an increasingly serious problem, since the intake of these substances into the body depends critically on lifestyle and diet, and both are becoming less and less natural for humans. An additional complication is the fact that a deficiency of such elements is most often not the first diagnosis: patients present with symptoms of inflammatory, infectious, metabolic, allergic, gastroenterological and many other disorders – and are treated specifically for them – while the underlying painful condition there lies a deficiency of one or another biologically active substance, which can clearly manifest itself only many years after the first noticeable disturbances appear.

2. Reasons

The definition of “nutritional” (food) implies and reflects the main cause of calcium deficiency: insufficient dietary intake. The largest amount of calcium available for absorption is found in dairy products (especially cottage cheese and butter), seafood, eggs, and vegetables. Since calcium is biochemically related to vitamin D, a lack of the latter most often leads to calcium deficiency; Thus, the reasons should also include insufficient exposure to the open sun. The most significant risk factors include smoking, situations of chronic stress, long-term use of certain medications (cytostatics, antiparoxysmal drugs, etc.). Visit our page

3. Symptoms and diagnosis

Classic symptoms of calcium deficiency include asthenia, frequent and painful muscle spasms (cramps), especially in the extremities, bone pain, caries, disorders of the immune and hematopoietic systems (in particular, a tendency to bleed due to insufficient clotting). In more severe and advanced cases, deformation of various structures of the musculoskeletal system, osteoporosis (thinning and fragility of bone tissue) and, as a consequence, frequent fractures are observed; urolithiasis, tooth decay, gastrointestinal, liver, kidney diseases; hypothyroidism, tetanic (muscular-spastic) attacks, tremor, multiple sclerosis. It is obvious that calcium deficiency is very dangerous in childhood, when the skeleton and other key systems of the body are being formed. Often such insufficiency is revealed during examination of patients with rickets; Often, children with calcium deficiency develop abnormalities in the structure of the lens of the eye, serious psychoneurological disorders, convulsive syndromes, flat feet, etc. Reduced blood clotting in childhood makes any scratch dangerous, and in some cases causes fatal bleeding. Calcium deficiency is preliminarily diagnosed based on the results of examination, history taking and study of the clinical picture. The diagnosis is confirmed by laboratory tests. About our clinic

4. Treatment

The most effective and natural way to restore the optimally required calcium concentration is a fortified diet. It should, however, be understood that any diets, like all other treatment regimens, activities, procedures, can be developed and prescribed exclusively by a doctor. The same applies to special calcium-containing supplements and drugs intended for the treatment of the most severe cases of calcium deficiency: such drugs can only be used as prescribed by a doctor.

At the Lab4U online laboratory, we want each of you to be able to manage your health. To do this, we simply and clearly tell you about the processes in the body!

Bones, teeth, cottage cheese, chalk. What do these words have in common? They all contain calcium. If your hair falls out, your nails break, your arms and legs “twist”, your back “aches”; increased sensitivity of the teeth, the back began to hunch – read the article to the end. Spoiler alert: Your body may be getting enough calcium, but something else is missing. If you don’t have these symptoms, also read the article, this is only a small part of the body’s signals that are associated with a lack of calcium. Or go straight to Conclusions.

Why is calcium needed?

The body contains calcium not only in bones and teeth (about 1 kg), but also in the blood (about 0,0013 kg). Calcium in bones is mainly needed to keep your skeleton strong and able to support you.

He has more responsibilities in his blood. He helps:

  • muscles contract;
  • nerves carry messages from the brain to every part of the body;
  • blood vessels move blood throughout the body;
  • release hormones and enzymes that affect almost every function in the human body;
  • blood clots (this is important, for example, to stop bleeding);
  • regulate blood pressure and bad cholesterol levels.

Unusual property of calcium
In Africa, calcium is used to treat. spider bites. It reduces muscle spasms.

What happens if I don’t get enough calcium?

For a very long time you will not notice the lack of calcium in the body. Calcium leaves the bones almost without you noticing.

You may suspect calcium deficiency if you have:

  • Constantly or periodically the bones “hurt”: the arms and legs “twist”, the back “aches”;
  • Dependence on weather conditions;
  • Sloping shoulders, hunching;
  • Unreasonable weight loss;
  • Muscle spasms and cramps;
  • Nails and hair break and peel;
  • Gray hair has appeared, and you are not even 30 years old;
  • Increased sensitivity of teeth, periodontal disease;
  • Tachycardia;
  • Prostration;
  • Tingling and numbness began in the hands;
  • Suddenly the voice changed.

These symptoms, as the first signs of problems with calcium metabolism, should prompt you or your doctor to check the mineral metabolism in the body. This is very simple to do – take a comprehensive “Mineral Metabolism” analysis. It is recommended to take it along with vitamin D. This will help you see the real root cause of a possible calcium deficiency.

You also need to keep your calcium levels under special control if you:

  • Smoke. The chemical elements that make up cigarettes replace calcium in the bones and block the production of vitamin D;
  • Drink alcohol. It destroys calcium molecules and then removes them from the body;
  • You drink coffee every day. Caffeine increases acid and alkalinity in the blood. To reduce their concentration, the body sends calcium from the bones into the blood. In addition, coffee contains compounds that, together with calcium, form calcium oxalate, the main component of kidney stones;
  • You are starving or on a diet. Calcium does not enter the body in the required amount, which means the process of pumping calcium from the bones into the blood is accelerated;
  • You don’t walk or move much. Without sunlight, vitamin D, which is needed for the absorption of calcium, is not synthesized by the skin;
  • Love to eat sweet and salty foods. Salt, sugar and “fast” carbohydrates inhibit the absorption of calcium in the intestines from food into the blood;
  • Vegetarian, vegan, or excluding animal products. It so happens that milk is the leader in calcium content. By eliminating it from your diet, you are missing out on a great source of calcium. Also, those who do not eat animal products most often have reduced vitamin D and phosphorus, the main partner of calcium.

Calcium is the cause of this disease.
It turns out that a fairly common cause of male infertility is a lack of calcium in the body.

If calcium is not absorbed by you or enters the body in insufficient quantities now, then in 15 years osteoporosis will most likely “knock” on you along with bone fractures.


The main disease caused by calcium deficiency is osteoporosis. This is a disease that affects the structure and strength of bones and increases the risk of fractures. Osteoporosis is one of the four leading causes of death and disability. In addition to osteoporosis, the TOP 4 includes cardiovascular diseases, diabetes mellitus and malignant tumors.

There are no early manifestations of osteoporosis – the process of bone destruction can take decades. Its main manifestation is fractures with minor injuries or without them at all.

Why is this disease dangerous?

It is rarely diagnosed in its early stages, and even less often treated, due to the lack of symptoms. Many people believe that if it doesn’t hurt, then there is no disease.

It is mistakenly believed that osteoporosis is a disease of older people. Yes, most of the registered patients are people over 50 years old. But the disease initially occurs when you are between 25 and 35.

According to Russian recommendations, assessment of the risk of osteoporosis and fractures should be carried out in all women and men over 50 years of age. However, if there is a risk of developing osteoporosis, doctors advise that everyone younger than this age be checked at least once a year.

You may be at risk of developing osteoporosis if:

  • There has been a history of osteoporosis in your family;
  • You are at risk of calcium deficiency;
  • You suffered fractures when you were slightly hit or fell from a small height;
  • Menopause occurred before age 45;
  • You are taking medications (steroids) to treat asthma, arthritis, or intestinal problems. Or if you have been taking antidepressants, anticonvulsants for more than a month;
  • You are a woman and have an irregular cycle;
  • You have definitely been diagnosed with a hormonal imbalance.

If at least one of the points applies to you, we advise you to undergo an examination and take an analysis that will evaluate your mineral metabolism. It will allow you to evaluate the processes of absorption, transport and release of calcium, phosphorus, magnesium in the bones and blood. Don’t forget to add a vitamin D test to it. Get tested and take it to your doctor (generalist or osteopath). Depending on the results, he will prescribe you the correct treatment or adjust it.

Why is excess calcium dangerous?

There is an opinion that a lot of calcium is good, and a little is bad. It is not true. Sometimes a prolonged increase in calcium levels is not noticeable, but significantly increases the risk of:

  • formation of stones in the kidneys, gall bladder and bladder;
  • formation of stones in the kidneys, gall bladder and bladder;
  • stomach ulcers;
  • hypertension;
  • vasoconstriction;
  • heart diseases.

Sometimes a person feels symptoms, but they are so nonspecific that it is very difficult to suspect a diagnosis based on them. Symptoms may include:

  • pain in muscles and bones;
  • frequent/profuse urination;
  • thirst;
  • itching;
  • abdominal pain, constipation;
  • weakness and fatigue;
  • depressed mood and memory loss;
  • nausea, vomiting and loss of appetite;
  • unexplained weight loss.

Calcium supplements
Unfortunately, the common “tradition” of taking calcium supplements “for prevention” can often be harmful to people’s health, since those taking such supplements receive too large doses of calcium. Calcium supplements should be treated like real medicine. Cannot be taken without a doctor’s prescription, not paying attention to the dosage and not knowing how much calcium you need.

How much calcium do I need?

We are not able to produce calcium like, for example, vitamin D (can be produced by the skin). Therefore, its level depends entirely on intake with food and its absorption in the intestines.

When food enters the body, calcium from it enters the bloodstream in the intestines. There, calcium is in three forms, one of which is ionized. It is with this that most of the effects of calcium on the body are associated. Calcium that does not enter the blood is excreted from the body through urine, feces and sweat.

The level of calcium in the blood and urine does not depend on gender, only on age.

From birth to 25 years of age, a person accumulates calcium, storing it in the bones. Simply put, our bones act as a kind of calcium storage bank. Even if you are healthy, after 35 years the body begins to “pump” calcium from the bones into the blood and by the age of 70 it loses about 30% of its reserves.

So how much calcium should you consume to maintain normal levels? According to the clinical recommendations of the Russian Osteoporosis Association, adults need to consume 1000 mg per day. For other individuals, the daily rate varies from 800 to 1500.

Men 1000 mg
Men older than 60 years 1200 mg
Women 1000 mg
Women older than 60 years 1200 mg
Pregnant (2nd half) 1500 mg
Nursing (1-6 months) 1600 mg
Nursing (7-12 months) 1600 mg
Infants (0-3 months) 400 mg
Infants (4-6 months) 500 mg
Infants (7-12 months) 600 mg
Children (1-3 years) 800 mg
Children (4-7 years old) 900 mg
Children (8-11 years old) 1100 mg
Boys (11-14 years old) 1200 mg
Girls (11-14 years old) 1200 mg
Boys (15-18 years old) 1200 mg
Girls (15-18 years old) 1200 mg

Who needs more calcium than 1000 mg:

  • Pregnant
  • Breastfeeding
  • For Children
  • People over 50 years old

If you lead a healthy lifestyle, drink 1 liters of water a day, eat dairy products once a day (preferably cottage cheese and milk), you get your daily calcium intake with food. But this does not mean that all of it will be assimilated.

Calcium and food
One of the leaders in calcium content is sesame. 100 grams of unhulled sesame contains about 1,5 grams of calcium. To get the most calcium from sesame seeds, soak them in water for 15-20 minutes before eating.
Calcium is better absorbed at night, so it is better to eat cottage cheese before bed.
Heat treatment converts calcium from “good” (which is absorbed) to “bad” (which is deposited in the kidneys, urinary and gall bladders). From this point of view, pasteurized milk is healthier than boiled milk.

The process of calcium absorption from food is affected by:

  • vitamin D. With a lack or deficiency of vitamin D, most of the calcium and phosphorus that enters the body is not absorbed;
  • phosphorus.If less than 1600 mg of phosphorus reaches us per day, then excess calcium in the blood may occur. But it will not get into the bones, but will be deposited in the vessels and organs;
  • magnesium.Calcium without magnesium instead of bones and teeth will strengthen muscles and other soft tissues. If there is not enough magnesium in the cells, calcium takes its place. Also, the less magnesium, the worse vitamin D is synthesized;
  • parathyroid hormoneMany people do not know that the body has parathyroid glands. These are 4 small glands behind the thyroid gland. When the concentration of calcium in the blood decreases, they secrete a special hormone (parathyroid hormone), which stimulates the leaching of calcium from the bones back into the blood and stimulates the formation of active forms of vitamin D, which facilitate the absorption of calcium from the intestines. When the concentration of calcium in the blood rises to the upper limit of normal, it affects the parathyroid glands, causing them to stop secreting parathyroid hormone. Then the absorption of calcium from the intestines slows down, and its excess is quickly deposited in the bones or excreted from the body along with urine. And as soon as calcium in the blood decreases, the cycle of parathyroid hormone production repeats again. If you take a test for parathyroid hormone and see that it is higher than normal (from 12 to 65 pg/ml), this may mean a lack of calcium and the beginning of bone tissue destruction;
  • calcitonin.Don’t worry if you don’t know what calcitonin is. Even those who closely monitor their health do not know about it. Calcitonin is a thyroid hormone. At its core, it is the complete opposite of parathyroid hormone. The action of calcitonin is aimed at reducing the level of calcium in the blood and inhibiting the process of bone destruction. As calcium levels increase in the blood, calcitonin concentrations also increase. Bone cells have special receptors on which calcitonin acts and increases the flow of calcium from the blood into the bone. This slows down the process of bone destruction.

If each of these indicators deviates from the norm, calcium metabolism is disrupted. Our body begins to think about how to compensate for the lack of calcium in the blood. And he follows the simplest path – to “pump” it from the bones into the blood.

This is why a total calcium test cannot show the real picture of what is happening to your bones. Lab4U laboratory experts advise taking the “Mineral Metabolism” complex along with a vitamin D test. These tests will show whether you have enough calcium or not.


Calcium is the basis of bones and an assistant in blood, muscles and blood vessels. He can play for a good team and help the body. Or he can join the team of bad guys and destroy organs by depositing in them.

You can’t take calcium just like that, without measuring it in your blood and without a doctor’s prescription.

Calcium enters our body with food or supplements. Calcium passes from the blood to the bone and, more often, back – from the bones to the blood, destroying them. Donating blood only for general calcium is not very informative. It is necessary to evaluate ionized calcium. Since the process of calcium absorption is affected by vitamin D, phosphorus, magnesium, parathyroid hormone and calcitonin, they need to be checked together.

This is very simple to do: take the “Mineral Metabolism” complex along with a vitamin D test. Take the results to a therapist or osteopath. He will evaluate them and possibly prescribe treatment.
