Renforcer vos os, c'est possible !

Strengthening your bones is possible!

What are we talking about ?

Skeletal system

The skeletal system is made up of 206 bones in adulthood. It is made up of a rib cage that encircles the viscera, and a spinal column, from which the upper and lower limbs extend, through the scapular (shoulder blades and collarbones) and pelvic (the pelvis) belts. At the top of this system is the skull.

What are the roles of this set?

The skeletal system is present for multiple reasons. Among others:

  • Supports the body: with this framework made up of the different bones and segments.
  • Provides protection for organs and viscera: with the skull, thorax and pelvis.
  • Offers a reserve of minerals: particularly calcium and phosphorus.
  • Manufactures blood cells: from bone marrow.

Maintenance of bone capital with calcium!


Most abundant mineral in the human body. Present mainly in bones and teeth (99%), and representing approximately 1kg in adults, calcium is necessary to ensure a strong skeletal system, and to guarantee good health in general.

Roles of calcium in the skeletal system


Bone mineralization

Calcium is involved in bone growth in children and the maintenance of bone capital in adults.

Muscle contraction

It allows the muscles to contract but also to relax. Calcium is therefore essential for the heart muscle, which functions independently.

Blood clotting

Tissue healing and blood clotting are partly ensured by calcium.

brain function

Calcium is essential for nerve impulses and neuromuscular excitability. Therefore, it is necessary to increase its sports efficiency.

Calcium sources

Taking into account an optimal intake of approximately 1000mg of calcium for an adult, the best sources of calcium are as follows:

  • Food supplements
  • Cheeses
  • Goat or cow milk
  • Yogurt
  • Canned sardine with bones
  • White beans
  • collard greens
  • Spinach
  • Some calcium-rich waters

Calcium deficiencies

The lack of calcium intake is automatically regulated by the body by drawing this lack from the bone tissue. If this condition is prolonged, complications may occur:

  • Rickets
  • Osteoporosis
  • Increased fracture risk
  • Thyroid disorder, in association with vitamin D deficiency.

Tips for maintaining your bones

Supplementing with calcium to ensure an optimal supply of this mineral for the body is a highly recommended option in order to maintain bone capital and prevent osteoporosis. In addition, adding magnesium to calcium will promote its fixation and contribute to the preservation of bone structure. This is also the reason why at Ironshark Nutrition you will always find your calcium accompanied by magnesium.
It is also important to note that for greater efficiency, a good supply of vitamin D , in addition to the effects mentioned in a previous article , will increase the assimilation and fixation of calcium on the bones.
