Jarrow Formulas Vitamin D3 400iu (100gels)

Vitamin D is a fat soluble vitamin. Vitamin D exists in several forms, each with a different level of activity. Calciferol is the most active form of vitamin D. Other forms are relatively inactive in the body. The liver and kidney help convert vitamin D to its active hormone form. Once vitamin D is produced in the skin or consumed in food, it requires chemical conversion in the liver and kidney to form dihydroxyvitamin D, the physiologically active form of vitamin D. Active vitamin D functions as a hormone because it sends a message to the intestines to increase the absorption of calcium and phosphorus.

Vitamin D Benefits:

• Vitamin D plays an important role in the maintenance of organ systems.
• Vitamin D regulates the calcium and phosphorus levels in the blood by promoting their absorption from food in the intestines, and by promoting re-absorption of calcium in the kidneys.
• It promotes bone formation and mineralization and is essential in the development of an intact and strong skeleton.
• It inhibits parathyroid hormone secretion from the parathyroid gland.
• Vitamin D affects the immune system by promoting immunosuppression, phagocytosis, and anti-tumor activity.

The major biologic function of vitamin D is to maintain normal blood levels of calcium and phosphorus. By promoting calcium absorption, vitamin D helps to form and maintain strong bones. Vitamin D also works in concert with a number of other vitamins, minerals, and hormones to promote bone mineralization. Without vitamin D, bones can become thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults, two forms of skeletal diseases that weaken bones. Nutrient deficiencies are usually the result of dietary inadequacy, impaired absorption and utilization, increased requirement, or increased excretion (loss). A deficiency of vitamin D can occur:

• when usual intake is below recommended levels
• when there is limited exposure to sunlight
• when the kidney cannot convert vitamin D to its active hormone form.
• when someone cannot adequately absorb vitamin D from the digestive tract.

Jarrow Formulas Vitamin D3 (cholecalciferol) is from purified fish liver oil and is free of Vitamin A. Fat soluable Vitamin D3 is converted by the kidneys into the hormone calcitriol, the activated form of Vitamin D3 which affects a variety of target tissues including bone, intestine, muscle, brain, skin and immune system cells. Calcitriol enhances calcium and phosphorus absorption and stimulates the synthesis of osteocalcin, an important structural protein in bone. Also, calcitriol is involved in proper cell differentitaion (changing cell function).
