High Absorption Our unique formulation ensures the iron remains fully intact as it passes through the gastric acid environment in your stomach, to then be absorbed across the entire small intestine. This means superior absorption and better bioavailability. Minimal Side Effects Since the iron gets absorbed directly to the cells in your intestine rather than your stomach, common gastro disturbances are significantly reduced. This makes Ferosom non-irritating to the stomach. Convenient Ferosom Capsules require only one dose per day and can be taken with or without food. Absorption is not affected by foods/drinks that contain caffeine or calcium.
