Liposomal Iron : It is a form of iron that is in the oral form that is as good as Intravenous iron, research as shown. Thus liposomal iron is currently the most superior type of iron.
Basically, iron is transported through a liposome that is like a car that ensures that iron reaches to the intestines where the absorption of iron happens safely. It is thus not altered by any food or by acidity in the stomach. Moreover, it doesn't have the typical side effects of elemental iron like constipation or GI upset that makes it much more tolerated by patients with faster absorption and repletion of iron stores.
