ESSENTIAL IMMUNE SUPPORT: Vitamin D is crucial for supporting healthy immune function.* Studies show that vitamin D deficiency is extremely common, especially in winter or when you are stuck indoors. SUPPORTS HEALTHY BONES: Vitamin D is necessary for your body to absorb calcium for strong, healthy bones and teeth. Risk of bone loss increases with age, particularly for women, and is also a risk during pregnancy.* HIGH POTENCY: 2500 IU and/or 5000 IU of naturally bioactive Vitamin D3 can help restore blood levels in those who are deficient. Studies show that nearly half the U.S. population may be low in Vitamin D.*
