The intake of an iron supplement is usually recommended whenever dietary iron ingestion is insufficient to meet the body’s normally required level. The lack of iron frequently leads to Anemia as well as other health related problems. After deciding which iron supplement to take, it is always important to remember that the organically combined form of iron, similar to TWINLAB Iron, is better tolerated by the stomach and has no constipation effects. This is why TWINLAB Iron differs from the rest, as its potent content is easily absorbed by the body. For the best results, it is recommended that it should be taken at mealtimes.
