400 IU Vitamin D is 100% of the recommended daily value. However, many health benefits have been found at doses greater than 400 IU.

All ingredients are provided in one easy-to-swallow softgel. Extensive research has found that high amounts of Vitamin D support cardiovascular health and promote bone & muscle strength. Vitamin D3 is the natural form of Vitamin D and is more powerful than Vitamin D2.
