As our knowledge increases of ways vitamin D is vital to our health, it is also increasing as to how lifestyle factors have created higher levels of vitamin D insufficiency. Diminished time outside, frequent use of sunscreen, and living at latitudes with scarce winter sunlight can all negatively affect vitamin D levels. Vitamin D’s role in helping the body absorb and retain both calcium and phosphorus is critical to building bone.

What is Vitamin D-3?

Vitamin D-3 is a fat-soluble vitamin that has long been studied as an essential nutrient for bone health. It is also a critical nutrient for immune system function. Deficiency in vitamin D is associated with increased autoimmunity as well as increased susceptibility to infection [1]. Vitamin D may also have an effect on mental health, as deficiency has also been associated with low mood and impaired cognitive performance [2]. Although vitamin D can be synthesized in the skin upon exposure to sunlight, many environmental factors result in a significant portion of the population having sub-optimal vitamin D levels. 

 

How does Vitamin D-3 Work?

Vitamin D is required for normal bone growth and maintenance. Metabolized in the liver to its metabolically active form (1,25-dihydroxyvitamin D), it regulates the expression of hundreds of genes involved in biological functions (skeletal and otherwise) by binding to the vitamin D receptor (VDR). Vitamin D is essential for the efficient use of calcium by the body and works in concert with the parathyroid glands to maintain serum calcium levels in the narrow range needed for nervous system function and bone mineralization [3].

Vitamin D is also a potent immune system modulator. The vitamin D receptor (VDR) is expressed by most cells of the immune system, indicating that vitamin D has a variety of effects that may enhance innate immunity and inhibit the development of autoimmunity [1]. Because vitamin D deficiency may compromise the integrity of the immune system, it has been linked to many autoimmune conditions [1]. The VDR also regulates other biological functions, including insulin secretion and blood pressure maintenance.

Vitamin D can only be made endogenously in a healthy body, in response to regular sun exposure. Moreover, the more melanin (dark pigment) in your skin, the more sun exposure required to make sufficient vitamin D. Therefore, the risk factors for vitamin D deficiency include use of sunscreen, living in Northern latitudes, indoor or night shift lifestyles, dark skin pigmentation, older age, genetic variations, impaired renal function, and fat malabsorption syndromes.

Consult your healthcare professional to determine which dose of vitamin D is right for you, as 

Metabolic Maintenance offers a range of doses, depending on your level of need. Please note that physician monitoring of vitamin D status is recommended while taking this product. Measurement of total serum 25-hydroxyvitamin D concentration is currently considered the best indicator to evaluate vitamin D status.
