While studies show that 2000 IU to 10,000 IU per day may be needed for optimal health, most Americans get less than 400 IU. Vitamin-D 5000 IU is designed for those who do not get 30 minutes of sun exposure (no sunblock) per day. Those who do may wish to use Vitamin D 5000 instead. This product may be used with any multiple that does not supply more than 1000 IU's of Vitamin D per day. |
