Health Factory Nano Iron is a revolutionary new form of iron supplement with two clear advantages over regular iron products. (1) Unlike conventional iron supplements it causes no intestinal distress or inflammation. It’s just exceptionally effective at improving iron status with minimal side effects, and no negative impact on intestinal flora. (2) Nano sized particles demonstrate radically improved bio-availability over conventional products due to their tiny size. Delivered faster, you need less nano iron for a comparable or even better result than other iron products. Nano Iron is 100% pure and free from additives.
