2000 IU of Vitamin D from 100% Pure Cholecalciferol
About Vitamin-D 2000 IU
While studies show that 2,000 IU to 10,000 IU per day may be needed for optimal health, most Americans get less than 400 IU per day. Vitamin-D 2000 IU is designed for those who get 30 minutes of daily exposure to sunlight (no sunblock). Those who do not may wish to use Vitamin-D 5000 instead.
