Vitamin D

Jarrow FORMULAS® Vitamin D3 provides cholecalciferol; the most bioavailable form of vitamin D. Vitamin D3 is converted by the kidneys into the hormone calcitriol; the active form of vitamin D3. Calcitriol enhances calcium and phosphorous absorption; stimulates the synthesis of osteocalcin (an important structural protein in bone); and is involved in proper cell differentiation (changing of cell function); including in prostate cells.*

HEALTH CLAIM: Adequate calcium and vitamin D as part of a healthful diet; along with physical activity; may reduce the risk of osteoporosis later in life.

Vitamin D has known beneficial effects on mineral absorption and bone mineralization. Though sunlight triggers the body's natural Vitamin D factory many health professionals have urged people to avoid excessive exposure to the sun.

The fat-soluble vitamin D's most important role is maintaining blood levels of calcium which it accomplishes by increasing absorption of calcium from food and reducing urinary calcium loss. Both effects keep calcium in the body and therefore spare the calcium that is stored in bones.

The benefits of Vitamin D3 run from supporting healthy bones to aiding the immune system.* D3 assists the body with calcium absorption – if calcium is not absorbed properly, bodily systems in need will take it from the bones.* D3 supports the immune system* D3 strengthens breast, colon and pancreas health* One of the primary natural sources of Vitamin D is the sun, so supplementation can be essential during winter, in northern climates, and during summer if you use sunscreen. Vitamin D absorption declines with age
