D3 Active 5,000

D3 Active 5,000 contains vitamin D3 (cholecalciferol) in convenient softgels. Vitamin D3 is the bioidentical form of vitamin D synthesized in the body from cholesterol, following activation by the UV rays in sunlight. This form is excellent for maintaining healthy levels of vitamin D in the body. Mounting evidence suggests roles for vitamin D not only in bone health, but also in supporting immune, neurological, musculoskeletal, cellular, and cardiovascular health.*

While vitamin D3 (cholecalciferol) is made in the skin when 7-dehydrocholesterol reacts with sunlight, many things affect the degree to which this biosynthesis occurs, including time of day, seasons, location, smog/pollution, clothing, shade of skin (darker skin requires more sun), and sunscreen use. Low-cholesterol diets and certain cholesterol therapies can also affect vitamin D formation. By some estimates, one billion people worldwide have vitamin D deficiency or insufficiency. Reversing deficiency and maintaining optimal serum vitamin D levels beneficially impacts biochemistry and numerous body systems; this is largely because calcitriol—the metabolic product of vitamin D—is a secosteroid hormone that targets over 200 genes in a wide variety of tissues. As the research demonstrates, vitamin D is clearly imperative for the development, growth, and maintenance of a healthy body from gestation to senescence.

Bone Health
The body needs vitamin D to absorb calcium, and the importance of vitamin D in skeletal health and bone density is well established. Although bone density is most often associated with calcium intakes, insufficient vitamin D negatively affects calcium absorption. Without adequate absorption, the body must take calcium from its stores in the skeleton, which weakens existing bone and prevents the formation of strong, new bone. Clinical research shows that taking vitamin D orally with calcium supplements can support healthy bone turnover, and adequate calcium and vitamin D throughout life—as part of a well-balanced diet—may reduce the risk of osteoporosis.

The Expanding Roles of Vitamin D
The role of vitamin D in good health continues to expand as the knowledge of this vitamin’s effects on different body systems grows. Research now suggests that optimal serum levels of vitamin D support normal cell differentiation, cardiovascular health, normal immune function, good balance, healthy mood, normal fetal development, neuronal growth and neurodevelopment, healthy glucose metabolism, musculoskeletal comfort, periodontal health, and normal intestinal immune responses. Areas of research that have gained momentum over the past several years concern the relationship of vitamin D deficiency or insufficiency to changes in cellular proliferation, changes in fetal brain development, and mental health. Evidence is also mounting that vitamin D supplementation may provide key immune support.

D2, D3, and Metabolites
As previously stated, D3 is the form of vitamin D produced in the skin. D2 (ergocalciferol) is derived from fungal sources by activating ergosterol with ultraviolet light. It is not naturally present in the human body. After vitamin D is formed in the skin or taken orally, it is metabolized into two different substances within the body: calcidiol (25-hydroxyvitamin D) and calcitriol (1,25-dihydroxyvitamin D). Calcidiol is the body’s main storage form of vitamin D, while calcitriol (made from calcidoil) is “activated” vitamin D. Although D2 and D3 are similar biochemically, a recent study reported D3 to be approximately 87% more potent in raising and maintaining serum calcidiol concentrations and in producing two- to threefold greater storage of vitamin D than did equimolar D2.

Melatonin 6 MG (Slow Release)

Melatonin 6MG (Slow Release) provides 6 mg melatonin in a sustained release tablet. The hormone melatonin is secreted by the pineal gland. As a supplement, it is useful for regulating sleep and the body's daily rhythmic cycle, making it ideal for jet lag. Melatonin is also an important antioxidant which acts as an effective scavenger of free radicals. Various factors may cause melatonin levels to become low, such as inadequate dietary intake of its precursors (tryptophan and serotonin), normal aging, insufficient exposure to natural light, and certain medications. Melatonin may support a healthy immune and stress response. Made with non-GMO ingredients.
