This iron formula has been carefully balanced with vitamin B12, a nutrient responsible for normal energy metabolism, and the amino acid lysine, known to aid iron absorption. At the recommended daily intake of 2 tablets, our formula provides a generous 20mg of elemental iron, 250μg of vitamin B12 (in the well absorbed methylcobalamin form) and 1000mg of USP grade lysine. The bisglycinate form of iron is well tolerated, meaning the tablets can be taken on an empty stomach.
