It is estimated 40%-75% of people are Vitamin D deficient. Vitamin D is produced in the body in response to sun exposure. Vitamin D can also be acquired through certain foods and nutritional supplements. Vitamin D is not abundant in our food choices and the sun is not a reliable source for everyone. Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal bone mineralization and to prevent the involuntary contraction of muscles that leads to cramps and spasms.
Vitamin D is important in:
Promoting healthy bones and teeth
Supporting immune, brain, and nervous system health
Glucose metabolism by regulating insulin levels and supporting diabetes management
Supporting lung function and cardiovascular health
Influencing the expression of genes involved in cancer development
Reduction of inflammation as well as modulation of such processes as cell growth.
