Vitamin D is one of many nutrients our bodies need to stay healthy. Among the vitamin’s main functions, it helps the body:
- Absorb calcium. Vitamin D, along with calcium, helps build bones and keep bones strong and healthy.
- Block the release of parathyroid hormone. This hormone reabsorbs bone tissue, which makes bones thin and brittle.
Vitamin D may also play a role in muscle function and the immune system. The immune system is your body’s defense system. It helps protect it against infections and other illnesses. Taking vitamin D every day has been shown to reduce the risk of falling in older individuals.
The newest cross-sectional research conducted by Atkinson MA and co-workers indicates strict relationship between decreased vitamin D level in the organism and increased presence of anemia. The subject group was composed of 10410 children and youth at the age of 1 to 21.
One may come across the information (based on this study) claiming unequivocally that lowered vitamin D level in the organism causes anemia and in fact it may be the case. However, it may also be different. Lowered vitamin D level may be only the effect and not the cause of anemia. The most current research do not show unambiguously if the lowered vitamin D level causes anemia or if the anemia influences the level of the vitamin in question. It is only known, that these factors are somehow dependent. More research is needed.
Certainly, the above mentioned unknown factor does not understate the merits of vitamin D in the prophylaxis of other diseases.
HOW DOES IT REALTE TO PHYSICALLY ACTIVE PEOPLE?
Anemia is identified with the reduced number of red cells. Along with the lowering number of red cells, the ability to transport oxygen also decreases (oxygenation of cells). This can lead to faster fatigue and weaker post-workout recovery. Therefore, it is worth tracking the news on vitamin D meaning in the above mentioned matter.
