IRON IS THE MOST COMMON NUTRIENT DEFICIENCY IN THE WORLD * If you find yourself unable to focus, battling fatigue, have feelings of muscle weakness, or just can’t get warm, you might be low in iron. And you’re not alone: The CDC reports approximately 10% of U.S. women between 12-49 years of age are iron deficient. MegaFood® Blood Builder® is a best-selling product for a reason: it's clinically shown to increase iron levels and reduce fatigue without common gastrointestinal side effects such as nausea or constipation†.* Designed to build the blood, we make it with real food 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 it’s gentle enough to take any time of day, even on an empty stomach.
