Vitamin D3 600 Supplement
Vitamin D, commonly called the sunshine vitamin, is one of the most highly recommended supplements by healthcare professionals today. Vitamin D is naturally obtained by sunlight and by consuming certain foods like fatty fish, mushrooms and egg yolks. However, most individuals in the United States consume less than recommended amounts, so supplementation may be a great option.
Adequate levels of Vitamin D can promote bone health, a healthy immune response (by activating T and B cells of the immune system), metabolism and overall health. Vitamin D may also support blood sugar and blood pressure levels already within a normal range. Inadequate Vitamin D levels may lead to rickets, bone and muscle discomfort, enlarged joints, easily fractured bones and improper immune system function.†

The Science Behind Vitamin D3
Research from the Journal of Investigative Medicine explains how supplementing with vitamin D can be beneficial for the immune system in humans. The vitamin D receptor is expressed on immune cells (B cells, T cells and antigen presenting cells). Vitamin D can modulate the innate and adaptive immune responses. Deficiency in vitamin D is associated with increased autoimmunity as well as an increased susceptibility to infection. 
Research from Therapeutic Advances in Musculoskeletal Disease states how supplementation with vitamin D3 helps with maintaining healthy bone mineral density, especially in older adults. As we age, calcium absorption decreases as a result of a number of factors such as lack of sun exposure and physical activity. Supplementing with vitamin D was found to improve vitamin D serum concentrations and calcium absorption helping with improved bone mineral density. 
Research in the Jomes Journal of Obesity and Metabolic Syndrome states that vitamin D3 plays a major role in the functioning of our metabolism. The presence of vitamin D receptors in a number of tissues implies that vitamin D has various physiological roles apart from calcium and phosphorus metabolism. Various studies reported that vitamin D insufficiency or deficiency is linked with metabolic syndrome risk. Vitamin D supplementation helps to support healthy body composition, blood sugar metabolism, and healthy heart function.
