Now High Potency 1000IU Vitamin D3 Softgels provides this essential vitamin in a highly absorbable liquid softgel form. Vitamin D is generally obtained through diet or generated by the skin in response to the sun's UV light. As more people avoid sun exposure, vitamin D supplementation becomes increasingly important to ensure that your body gets an adequate supply. As we age, our body may absorb this essential nutrient less effectively. Vitamin D insufficiency has been linked to mood disorders, chronic diseases, and autoimmune diseases over time. Vitamin D improves calcium absorption in the gut and maintains proper serum calcium and phosphate concentrations, allowing for normal bone mineralization and preventing hypocalcemic tetany. It is also required for bone formation and remodeling by osteoblasts and osteoclasts. Without enough Vitamin D, bones can become thin, brittle, and deformed. Vitamin D regulates calcium and phosphorus intake and promotes appropriate immune system function. Getting enough vitamin D is essential for appropriate bone and tooth growth and development, as well as increased resistance to some diseases. The new High Potency Vitamin D3 formulation helps to maintain bones and teeth while also supporting the immune, brain, and nerve systems.
