Show your immune system some love with Nature’s Bounty Vitamin D3, a simple and effective way to get your daily dose of this important vitamin.* As a more potent form of Vitamin D, Vitamin D3 is an essential nutrient for immune support that may assist the immune system by helping to regulate T and B-lymphocytes (cells that are major components of your immune response).* Vitamin D is known as the “sunshine vitamin.” However, many people don’t get enough of it due to working and living indoors, especially during the winter. Nature’s Bounty Vitamin D3 provides 125 mcg (5,000 IU) of Vitamin D per serving in one easy-to-take rapid-release softgel, so you can get your daily dose of the sunshine vitamin all year long. For additional wellness benefits, Nature’s Bounty Vitamin D3 also helps maintain healthy bones in adults, as Vitamin D3 assists the body with calcium absorption.* Plus, our formula is non-GMO, free of gluten and sugar free, and contains no artificial colors or sweeteners.
