WHY VITAMIN D: With age, the way the body absorbs Vitamin D can become inefficient over time. Vitamin D is required in order to promote the absorption of calcium which is key in maintaining healthy teeth and bones. Vitamin D also helps support a healthy immune system and neuromuscular function. BODY BENEFITS: The Vitamin D3 in these softgels is the same form of Vitamin D3 that your body produces when your skin is exposed to sunlight which promotes tissue health. In addition, Vitamin D3 supports and maintains healthy bones, teeth and immune system.
