The level of the male hormone testosterone depends on the amount of vitamin D, which is produced under the influence of sunlight.

Australian scientists conducted a study with the participation of 3 thousand representatives of the stylish sex. For three years of each season, scientists measured testosterone levels and vitamin D levels in subjects.. The highest level of substances was observed in summer, in winter it decreased significantly, and in spring it was the lowest..

If the level of testosterone in a man is low, then the male libido decreases, as well as the energy of the man.. Vitamin D protects bones and plays an important role in the body's sensitivity to skin and heart disease and cancer.

Due to a sufficient amount of this vitamin in the body, its immune-protective forces increase, the normal functioning of the thyroid gland and normal blood clotting occur..
