Patient One Vitamin D3 5000 IU supplies cholecalciferol, a highly absorbable and bioavailable form of vitamin D (from lanolin), for optimal nutritional benefits for the skeletal, cardiovascular and immune systems. Vitamin D3 is the naturally occurring form of vitamin D synthesized in humans. Studies show that plant-derived D2 is metabolized differently than D3 and that D3 may be over 3 times more effective than D2 in raising and maintaining serum vitamin D levels.
Vitamin D3 is most noted for optimizing calcium bioavailability, thereby promoting peak bone mass and bone strength. Patient One Vitamin D3 5000 IU is a professional-strength medinutritional formula that promotes compliance through once-a-day high-potency administration.
D3 5000 IU:
Patient One supplies a high-level 5000 IU serving of superior quality cholecalciferol D3 to compensate for nutritional challenges related to deficiency, lack of sun exposure, and poor absorbability. Vitamin D production is reduced by anything that decreases the intensity of the sun's rays, such as cloud cover, seasons, time of day, smog, use of sunblock, and skin melanin content. There are very few dietary sources of Vitamin D. Fatty fish and fortified milk are the best sources, although these foods may not provide enough Vitamin D. In addition, Vitamin D levels decline with age.
75% of Americans fail to reach recommended daily vitamin D intake, which doubles between ages 51 and 70, and triples over age 71 – making vitamin D supplementation increasingly important as we age. Patient One Vitamin D3 promotes peak bone density and skeletal strength. D3’s ability to promote normal cell growth and metabolism provides additional benefits for cardiovascular, breast, colon, prostate and immune health.
