News Picks : Nano-iron supplements shown to be safer in treating anemia

By: Physics Today
31 July 2014

New Scientist: Because current iron supplements can cause constipation and diarrhea, researchers have been working on a synthetic alternative. The researchers developed five synthetic formulations of iron nanoparticles to which they attached organic acids to make the product more closely resemble ferritin, the natural dietary iron found in meat and leafy green vegetables. They then tested the nano-iron in mice before trying it out on premenopausal women, a group that often suffers from anemia. Although the formulation that worked best was just 80% as effective as standard supplements, it had none of the side effects. More testing will be required before the product is ready for mass marketing.
