Daily, drink entire contents of one pur-Absorb packet. pur-Absorb is ideally taken diluted in orange juice as Vitamin C (e.g. in a glass of orange juice) is well recognized to improve the body's ability to absorb iron. If you cannot tolerate orange juice try apple, mango, pineapple, or tomato juice – all rich in Vitamin C but low in tannins. pur-Absorb can also be effectively taken on-the-go straight from the packet or diluted in water.
