Studies carried out by J.A. Vinson in the USA indicate that Food Base Iron is more bioavailable than isolated chemical Iron at 100%. Results show the Food Base product is 200% more (2 times more) bioavailable in the blood and 70% better retained than amino acid chelated iron. Note also that extensive use indicates that in the Food Base form the Iron has not been shown to cause constipation problems.

Studies carried out on Iron are:
1. Vinson JA., "Bioavailability of Iron", Unpublished Data, 1981.
'The Yeast was the most bioavailable form of iron when measured in both the blood and the liver.'
2. Vinson, J.A. and Bose, P., "Comparison of the Bioavailability of Trace Elements in Inorganic salts, Amino Acid Chelates and Yeast", Proceedings on Mineral Elements, 615-621, 1981.
'The Relative bioavailability in both blood and liver was yeast "> inorganic "> chelate. The results show that yeast is the most bioavailable form of the element. It is thus concluded that yeast is the best form for trace element supplementation.'
3. Vinson J.A.; "Human skin absorption of Iron Yeast", Unpublished Data, 1988.
'The iron was absorbed very well, and the amount absorbed increased linearly with time of exposure.'
4. Vinson J.A.; Bose P.; Lemoine L. and Hsaio K., 1989 in Southgate D.A.T.; Johnson I.T. and Fenwick G.R., (Eds.), Nutrient Availability: Chemical and Biological Aspects, 125-127, Royal Society of Chemistry, Thomas Graham House, Cambridge, U.K.
'Yeast trace elements and natural vitamins are more slowly absorbed in animals and man; are more bioavailable; and are therefore the preferred form for supplementation.' |
