For decades, vitamin D’s sole health benefit was thought to lie in the prevention of bone weakening caused by deficiency. It is now known that it is also involved with numerous other health processes, including the immune system and brain function. Research has also shown that adequate levels of vitamin D support healthy blood sugar levels and protect the health of the breast, prostate, bowel, and cardiovascular system. Yet with increased avoidance of direct sunlight, the rates of deficiency have risen to where it is estimated that less than 20% of the population gets enough vitamin D.
Vitamin D is best known, of course, for helping the body absorb calcium and deposit it into the bones. Research indicates that suboptimal levels of vitamin D may result in calcium being deposited in the kidney, brain, heart, and other soft tissues.
Vitamin-D 5000 IU is designed for those who get less than 30 minutes daily of unprotected exposure to sunlight.
