vitamin-d and calcium diet medicines

The question of how to increase calcium in the blood is becoming increasingly important, since calcium is one of the most important elements in a person’s diet.

Why Calcium is Needed ?


  • Calcium is a structural component of bones, teeth, and soft tissue.
  • It is very important in many metabolic processes in the body.
  • Calcium accounts for 1 to 2% of the body weight of an adult, 99% of which is stored in bones and teeth. At the cellular level, calcium is used to regulate the permeability and electrical conductivity of biological membranes (for example, cell walls) that control muscle and nerve functions, secretion of glands and blood vessels, and their elasticity.
  • Calcium is also needed to ensure blood clotting.
  • The average rate of calcium in the blood for an adult is 2.15 – 2.50 mol / liter.
  • A decrease in this indicator is rather undesirable and may be due to a number of dangerous diseases. In this case, you have to think about how to increase calcium in the blood.
  • With a sharp decrease in the level of calcium in the body, first of all, diseases such as osteoporosis, diseases of the cardiovascular system, enlargement of the thyroid gland, and the presence of malignant tumors should be excluded. Unfortunately, the growth of these diseases among the population today has become critical.

Causes of decreased blood calcium

The list of causes of calcium reduction in the body is quite extensive. First of all, it should be noted that calcium enters the body through food and water.

Therefore, today the question of how to increase calcium in the blood, especially worries people who abuse unbalanced diets and starvation.

Women are also at risk during pregnancy and lactation, in the postmenopausal period, as well as children during active growth.

  • Excessive consumption of coffee, smoking and frequent stress are also causes of high calcium consumption. That is why it is so important to know how to increase calcium in the blood.
  • Causes of calcium reduction can be problems of the digestive tract, such as intestinal dysbiosis, food allergies; diseases of the thyroid and parathyroid glands, kidney disease.
  • With an unbalanced diet, the place of calcium in the body can be taken by other chemical elements that do not allow the normal absorption of calcium.

These include iron, sodium, potassium, phosphorus, magnesium, as well as lead and zinc. A large role in the absorption of calcium is the presence of sufficient amount of vitamin D in the body.

Symptoms of low blood calcium

The manifestation of symptoms of low calcium in the blood usually does not take long to wait.

  • First of all, bones and muscles will react to the lack of this microcell, whose condition will worsen considerably.
  • Bones become porous and brittle, caries appears, heart palpitations are observed, and muscle spasms are observed.
  • Also, the lack of calcium affects the health of other organs.
  • In this case, the acute question arises: How to increase calcium in the blood?
  • People suffering from calcium deficiency look pale and lethargic, get tired quickly, and become lazy. They are more sensitive to cold weather.
  •  The most obvious symptom is sweating around the head, even in cold weather.
  • Nervousness and mental disorders can also be eloquent symptoms of low calcium in the blood.
  • Babies born to mothers whose blood calcium level was below the minimum norm usually also suffer from a lack of this trace element.
  • Calcium deficiency in these children becomes more noticeable if there is not a sufficient supply of calcium, proteins, minerals and vitamins that come with whole milk, fresh fruits and vegetables.
  • Children who have not received a sufficient amount of calcium stop growing, the development of muscle tissue slows down.
  • They have a bad appetite, and if fed by force, gag reflexes can occur.
  • There are also frequent stomach disorders and diarrhea.
  • Calcium deficiency reduces body resistance.
  • Such children become easy prey for respiratory and intestinal infections.

Parents of these children must necessarily have information on how to increase calcium in the blood.

  • Calcium deficiency in young girls causes late puberty, frequent disruptions of the menstrual cycle, excessive bleeding, anemia.
  • The body’s resistance against infections is reduced.

In the case of an insufficient amount of calcium during pregnancy, fetal development continues, relying on the reserve calcium from the mother’s bones, which can later cause her serious diseases.

  •  Bleeding, lack of breast milk, poor mental concentration, a long postpartum period are all common symptoms of low calcium in the blood after childbirth. In this case, a successful solution to the problem of how to increase calcium in the blood becomes particularly relevant.

Elderly people , due to lack of calcium in the blood , can cause exacerbation of chronic diseases and problems of the cardiovascular system, since the work of the heart, the elasticity of blood vessels and nerve fibers are directly related to the balance of calcium in the blood.

Whom to contact?

You should contact endocrinologist and nutritionist .

Treatment of low blood calcium

Treatment of low blood calcium should begin with balancing the diet. How to increase blood calcium?

  • First of all, you should pay attention to providing the body with a number of vitamins that contribute to the optimal absorption of calcium.
  • Vitamin D, allowing the body to absorb calcium from the intestine, due to its interaction with proteins necessary to transport calcium through the intestinal membrane into the bloodstream.
  • Vitamin D also helps maintain an optimal balance of calcium and phosphorus during bone mineralization.
  • Vitamin C also actively contributes to the absorption of additional calcium and enhances the body’s resistance against harmful fungi and bacteria (for example, Candida fungi), which also hamper the effective absorption of calcium.
  • Magnesium interacts with calcium in regulating the work of the cardiovascular system, muscular activity, circulatory and nervous systems.
  • The optimal ratio of calcium and magnesium is 2: 1, while it is very important that the magnesium indicator does not exceed the upper permissible limits.
  • Lactose is found in dairy products, helps in the absorption of calcium in the intestines of infants, although there is no evidence that this rule applies to adults.

As noted earlier, diet plays a pivotal role in deciding how to increase calcium in the blood. The main thing is to maintain its correct balance.

 For example, fats and proteins in our diet contribute to the absorption of calcium, but only if they are not consumed in excess.

Popular high-protein diets since the late 1990s actually help to reduce total calcium absorption by increasing the rate at which calcium from the body enters the intestine.

Foods that increase calcium in the blood

Much has already been said about the need for proper nutrition. But it is worthwhile to elaborate on the list of products that will help increase calcium in the blood.

  • People suffering from calcium deficiency, nutritionists recommend to include in your diet dairy products. This is a variety of cheeses, yogurts, milk (preferably low-fat or low-fat), etc.
  • Non-dairy products can also be a source of calcium. These include the following: salmon, sardines, kale, tofu, rhubarb, spinach, turnip, caviar, white beans, broccoli, peas, Brussels sprouts.
  • Frequent consumption of foods high in oxalic and phytic acids, as well as caffeine is not recommended. The harm of these trace elements to the body lies in their property to block calcium.
  • In large quantities oxalic acid is found in foods such as spinach, rhubarb, chocolate, cocoa, parsley, poppy seeds, beets, chard, carambola, nuts, berries, and beans. 
  • There is a lot of oxalic acid in tea leaves, although, fortunately for lovers of this product, oxalic acid in the drink itself is contained in a very limited quantity, since not so many leaves are used for brewing.
  • Phytic acid is another chemical element that inhibits calcium absorption. It is found in cereals, grains, seeds and nuts.
  • The level of concentration of phytic acid can be reduced by heat treatment of products, their soaking in an acidic medium, fermentation or by germination of grains.

As an example, it can be said that bread made from cereals does not actually interfere with calcium absorption, since when yeast is added to the starter dough, phytic acid decomposes.

It is important to note that phytin in fact does not belong to trace elements harmful to humans, it simply suppresses calcium absorption. So the use of products with a high content of phytic acid is quite possible, but in limited quantities.

With caffeine, things are about the same. If you drink coffee in moderate doses, then caffeine has a very small effect on the absorption of calcium. Reduce and compensate for the loss of calcium can, if the coffee add one or two tablespoons of milk.

Pills that increase calcium in the blood

How to increase blood calcium with pills?

 It is necessary to take tablets that increase calcium in the blood very carefully. It is important to follow the instructions and advice of doctors, since an excess of calcium in the blood is no less dangerous than its shortage.

There are established norms of calcium intake per day (including calcium that was ingested with food).

  •  Children aged 1 to 3 years old need 500 mg, from 4 to 8 years old – 800 mg;
  • Teenagers up to 18 years old need 1300 mg;
  • Adults aged 19 to 50 years – 1000 mg;
  • People older than 51 need 1200 mg of calcium per day.

Tablets that increase calcium in the blood, it is recommended to combine with taking vitamins D, C, and magnesium (for example, MAGNE-B6). Various multivitamins are also suitable.

Also of note is the positive role of protein in the absorption of calcium, in particular, the amino acids lysine and glycine.

Therefore, calcium supplements are often made in chelate form (not necessarily with these two amino acids). Chelated supplements are linked to amino acids, which help calcium to be better absorbed.

It should also not be forgotten that all medicines can cause side effects and should not be taken without the advice of a doctor.

How to increase blood calcium with drugs? 

Among the most famous drugs that help increase calcium, the following should be noted:

  • CALCIUM + ASCORBIC ACID (Calcium + ascorbic acid),
  • CALCIUM GLUCONATE (Calcii gluconas)
  • CALCIUM LACTATE (Calcii lactas
  • CALCIUM CHLORIDE (Calcii chloridum), etc.

Now you know how to increase calcium in blood . You can recommend these food products to the person whose calcium level is decreased . But do not recommend any medicine because only health practitioner can provide the required medicines. These medicines mentioned in this post are just for your knowledge . Always take your practitioner’s advice before taking any medicine.
