Geritol Liquid is an easy to swallow liquid supplement that provides you with energy support through a combination of high potency B-vitamins (B1, B2, Niacin, B6 & Pantothenic Acid) and 18mg of Ferric Ammonium Citrate, an iron that can be dissolved in water. Geritol Liquid can be taken once daily as a supplement, just like a regular daily multivitamin.
