Vitamin D is a fat-soluble vitamin that has the unique property of being able to be produced by the body from sunlight and does not depend solely on its intake through diet.

Approximately 75% of the world’s population has vitamin D levels below the normal limit of 30 ng/ml in the blood.

30 ng/ml in the blood is necessary as a minimum level for healthy bone function, but for the ideal functioning of the immune system and other systems, levels higher than 50 ng/ml in the blood are required.

Symptoms such as frequent fatigue, weakness, frequent infections and diseases, chronic pain, inflammation, hair loss, mood disorders may be due to low levels of vitamin D in our body.

Vitamin D and adipose tissue

Vitamin D is stored in adipose tissue and can only be released when the stored fatty acids are mobilized for energy.

Thus, isolated vitamin D in adipocytes should not be considered a functional depot, ready to be transported to the liver and then to the bloodstream when its levels in the body decrease.

Vitamin D and muscle tissue

It has been demonstrated that skeletal muscle cells incorporate the vitamin D binding protein from the blood into the cytoplasm of the cells. By a specific mechanism, this uptake and subsequent release of vitamin D into the bloodstream is constantly repeated.

Since the concentration of vitamin D in the blood decreases in winter, this cycle in and out of muscle cells seems to increase in order to maintain as much as possible a balance. Parathyroid hormone is the most likely factor that enhances the repeated cycle of vitamin D between skeletal muscle and blood. This mechanism attempts to maintain an adequate level of vitamin D in winter.

It has been observed that in conditions of protein and total calorie malnutrition there is increased breakdown of muscle protein to meet energy and essential amino acid needs. The breakdown of muscle protein and by extension muscle tissue explains the high incidence of vitamin D deficiency in malnourished individuals.

Vitamin D and proteins

Also, a diet containing at least small amounts of meat provides some protection against clinical vitamin D deficiency compared with a purely vegetarian diet.

The greater supply of essential amino acids from meat proteins compared with plant proteins may optimize protein metabolism in muscle, which could be related to the efficiency of the mechanism for maintaining vitamin D binding in muscle tissue.

Consistent adherence to an exercise program and proper nutrition would ensure that vitamin D status could improve even in the winter when people do not have as much opportunity to sunbathe, thus dramatically increasing vitamin D in their bodies.

If this is not possible due to circumstances, then taking a vitamin D supplement is more than necessary to maintain good health and the proper functioning of many of our body’s systems.
