Overview

MegaFood Blood Builder is the #1 selling iron supplement in the US, delivering 26mg of iron from whole food sources along with vitamin C, folate, and vitamin B12 for optimal iron absorption and red blood cell formation. What makes Blood Builder unique is its clinical study showing it increases iron levels without the nausea and constipation that plague most iron supplements. The iron is derived from Saccharomyces cerevisiae (nutritional yeast) grown on iron-enriched media.
