Vitamin D 4000 provides 4000 IU of Vitamin D. Most well known for its role in building bone, vitamin D is also a vital nutrient for cardiovascular and immune health.†
VITAMIN D3 PLAYS AN INTEGRAL ROLE IN CALCIUM ABSORPTION AND BONE HEALTH
- Immunomodulatory
- Supports healthy immune function
- Supports healthy skin
- Cytokine modulator
- Supports healthy cartilage and joints
- Supports healthy vascular tone
- May support healthy blood lipid levels
For many people, the principal source of vitamin D is through exposure of the skin to sunlight. Cholecalciferol, also known as vitamin D3, is formed from 7-dehydrocholesterol in the skin after exposure to UV light. Unfortunately, due to the risk of skin cancer, many individuals are limiting sunlight exposure or using liberal amounts of sun protective factors (SPF) in sun screen lotions, both of which limit vitamin D production in the skin. In the body, cholecalciferol is hydroxylated to calcidiol in the liver and then to calcitriol in the kidneys, which is the active form of vitamin D. The active form of vitamin D works with parathyroid hormone and calcitonin to regulate serum calcium and phosphorus concentrations.
VITAMIN D DEFICIENCY causes increased parathyroid hormone activity which acts to maintain serum calcium and phosphate concentrations at the expense of skeletal calcium.
BONE HEALTH: Various studies have found an association between low serum levels of vitamin D and joint disorders as well as decreased bone density. In addition, risk for progression of these disorders increases substantially with both low vitamin D intake and decreased serum levels. Some of the best results obtained in studies on bone health have supplemented patients with 700 - 800 IU vitamin D per day, which is considerably higher than the recommended 400 IU per day. The best results were obtained when vitamin D was given along with calcium.
IMMUNE AND ANTI-INFLAMMATORY SUPPORT: One researcher described vitamin D as a flexible bidirectional immunomodulator. The cytokines interleukin 1 (IL-1) and interleukin 2 (IL-2) appear to be regulated favorably under the influence of vitamin D.
HEALTHY SKIN: Topical vitamin D analogues have been shown to be effective in treatment of certain skin disorders. Vitamin D has anti-proliferative activity on keratinocytes and stimulated epidermal cell differentiation.
CARDIOVASCULAR SUPPORT: Epidemiological data indicates that a low vitamin D status is associated with vascular disorders. Clinical studies have demonstrated an inverse relationship between circulating vitamin D levels and plasma rennin activity. It should also be noted that vitamin D has been shown to inhibit lipid peroxidation.... Click here to continue reading
