Vitamin D is not a vitamin but instead is a powerful steroidal hormone. Its active form enhances immune cells’ creation of antimicrobial proteins.
The ideal levels in your body should be above 50 ng/ml with an optimal level of 70-80 ng/ml. Sunlight and supplementation are the only significant sources of vitamin D.
Vitamin D deficiency is a significant factor in several conditions that affect a high population in the world:
- Chronic low back pain, which may be associated with osteomalacia (i.e., softening of the bones due to a lack of vitamin D).
- Cancer; people living at higher latitudes (e.g., Canada, northern U.S., etc.) have a greater risk of dying from colon cancer than people who live closer to the equator and experienced greater sun exposure. A 2006 review article notes that the majority of studies examining the relationship between vitamin D status and cancer risk show that sufficient vitamin D levels do indeed reduce the risk of cancer and that supplementation is an affordable way to reduce cancer incidence and cancer-related deaths. Vitamin D deficiency may be associated with the following cancers: colorectal, cervical, breast and prostate.
- Risk of heart disease and hypertension have also been associated with vitamin D deficiency.
Get direct sunlight on your body for 15-20 maximum, and then apply the sunscreen. The sunscreen does not allow the Vitamin D to absorb in the body.
