Vitamin D3 and its benefits

Recently vitamin D is becoming a miracle hormone of sorts. We are talking about improving the physical and mental well being. But as more research studies, just how vast the vitamin’s value has the scientific community debating.  Technically, vitamin D is a type of hormone; it helps the body absorb calcium from food and plays a role in keeping bones dense. It’s hard to get from food sources alone, but most people can synthesize it in their skin when exposed to UVB light, which is present in sunlight. People in areas with several overcast days, older adults, and most women may benefit from a supplement. That being said many studies say to indicate that over 90% of the U.S. population has less than optimal levels.

Many other health benefits are associated with higher 25(OH)D concentrations, including reduced risk of autoimmune diseases (133), diabetes mellitus type 2 (134), adverse pregnancy and birth outcomes (135), respiratory tract infections (136), and all-cause mortality rate (137). Whether vitamin D reduces risk of cardiovascular disease is still uncertain based on support from observational studies but not clinical trials (138). Thus, raising 25(OH)D concentrations in an effort to reduce cancer risk will yield additional benefits. The optimal 25(OH)D concentration is certainly above 75 nmol/l and more likely 100-150 nmol/l. Reaching those concentrations could take 1,000-5,000 IU/d of vitamin D3 or a moderate amount of sensible sun exposure. The only way to ensure reaching the desired concentration is to have serum 25(OH)D concentration measured (1819).


The UVB–vitamin D–cancer hypothesis has considerable supporting scientific evidence from a variety of study types: geographical ecological, observational, and laboratory studies of mechanisms, as well as several clinical trials. At this time, the general public and individual physicians can spend a more reasonable time in the sun and use vitamin D3 to prevent and treat many cancers. Hopefully soon, the clinical evidence will be strong enough that health care systems and agencies will endorse vitamin D3 supplementation as a way to prevent and treat cancer.
