Spatone 100% Natural Liquid Iron - It is not actually how much iron we consume that matters but the amount of iron that our body is able to absorb. The absorption of iron is a very complex process and iron is generally recognized as a mineral that is difficult for our system to absorb. Spatone has been scientifically shown to have a bioavailability of iron (the amount of iron available to be absorbed) of 40%. This is much higher than the iron absorption from food sources (5 - 20%) or conventional iron supplements (3 - 10%). Spatone is thus a highly effective source of iron which can be consumed to help maintain healthy iron levels or to help prevent iron deficiency during pregnancy.
