Pure Essence Vitamin-d 5000 Iu, Capsules, 30-Count (Pack of 2)

What the brand says

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 2000 iu instead. This product may be used with any multiple that does not supply more than 1000 iu's of vitamin d per day.
