Known as the sunshine vitamin, Vitamin D3 capsules allow your body to get a daily dose of Vitamin D without the need of the sun’s rays. Vitamin D provides immune system support to improve the body’s natural defenses against disease and promotes a healthy heart. It also assists in supporting healthy bone growth, by assisting the body in calcium absorption. Vitamin D deficiencies can lead to numerous diseases such as osteoporosis, osteomalacia, and multiple sclerosis. Vitamin D deficiency can also lead to depression and anxiety due to a lack of serotonin absorption usually provided by the sun.
