This formula helps to supply the nutrient iron, Fe, to people that are low in this nutrient. This is a vegan friendly formula containing yellowdock, boldo leaf, spirulina and more. This can be added to your daily supplements if you are feeling run down and if you know your red-blood cell count is low and you need natural sourced iron to rebuild. The FDA does not approve of these statements and you are taking this at your own risk for 25 or 50 days. Excellent source for women for that time of the month to maintain red blood cell count. Highly asorbable as compared to "bed pan bullets," iron sulfide which is very hard to absorb. This formula was proven to keep up red blood cel support in an 84 year old man with a bleeding pulip in his large intestine. Remember the FDA requires that this is not to diagnose, treat, prevent or cure disease--Remember that the US FDA has never approved any herbal supplment or single plant but only pharmetical drugs. Contains: YELLOWDOCK root, Pfaffia root, nettle leaf, Boldo leaf and 1 more.
