MegaFood Blood Builder is one of our top-selling products for a reason: it’s clinically shown to increase iron levels without common gastrointestinal side effects such as nausea or constipation. It's made it with nourishing, whole foods, like beets and organic oranges, plus folic acid and B12 for healthy red blood cell production, and vitamin C to support iron absorption. Oh, and did we tell you it’s safe to take on an empty stomach? If building your blood without missing a beet (see what we did there?) sounds up your alley, this is the product for you.
