Role of calcium in the body

Responses on Calcium

Calcium is the most abundant mineral in the human body, about 1 to 1.2 kg in adults.

99% of this calcium contributes to the formation and strength of bones and teeth. Non-bone calcium , despite its small share (1%), is involved in multiple functions essential to the body: blood coagulation, muscle contraction, nerve conduction, hormone release, etc.

The level of calcium in the blood is maintained within very narrow limits, to the detriment of bone reserves. Thus, the impact of a diet that does not provide enough calcium (deficient diet) is only apparent when changes occur at the bone level (poor bone constitution in young people, decalcification in adults and the elderly person).

At any age, it is therefore essential to ensure permanent and sufficient coverage of calcium requirements .

Regular intakes of calcium

Having food intakes close to the values ​​of the recommended dietary allowances (ANC) ensures good coverage of calcium needs .

This is particularly true during childhood and adolescence, when the maximum bone capital is set up, as well as when physiological aging of the bone occurs.

Indeed, bone is a living tissue that forms and degrades throughout our lives. This phenomenon makes it possible to replace the old bone with young bone and to repair the various damage suffered by the bone.

During the first 20 years of life, the formation activity is higher than that of degradation, which leads to the acquisition and consolidation of bone capital . Then, from the age of 30, a physiological bone loss appears (the formation being insufficient to compensate for the degradation), followed by an amplification of this loss from the age of 50 in women and from the age of 60 in men. ; which constitutes a favorable ground for the development of osteoporosis .

Risk of deficiency and excess intake



Lack of Calcium

The signs of calcium deficiency are only apparent when medium and long-term changes occur at the bone level: disorders related to defects in the mineralization of osteoid tissue (rickets in children and osteomalacia in adults) or excessive loss of bone substance (osteoporosis in the elderly).

  • Osteomalacia and rickets are pathologies linked to a lack of accumulation of mineral elements in the skeleton.

We talk about osteomalacia in adults and rickets in growing children. They cause bone and muscle pain as well as bone deformities.

  • Osteoporosis results from a pathological accentuation of the aging of the bone and is characterized by a very low bone mass and a breakdown of the bone structure.

Its best-known manifestations are vertebral compression, wrist fractures and hip (femoral neck) fractures. This pathology is 3 times more common in women than in men.

In fact, between the ages of 30 and 80, women have lost an average of 45% of their initial bone capital, whereas this bone loss is only 15-20% in men.

Excess Calcium

In the long term, excessive calcium intakes can lead, in sensitive subjects, to hypercalciuria, and therefore to urolithiasis and nephrocalcinosis, a risk which may be increased in the event of hypervitaminosis D. In 2003, the SCF set a safety limit of 2500 mg/day.

Calcium supplementation can be a good alternative to avoid the risk of deficiencies and control intake.
