 Studies carried out by J.A. Vinson in the USA indicate that Food Base Zinc is more bioavailable than isolated chemical Zinc. Various results show the Food Base product is more slowly absorbed than Zinc sulphate and gluconate, 600% (6 times) more bioavailable than Zinc gluconate, 70% more bioavailable in the blood than Amino Acid chelate, less excreted in the urine than sulphate and gluconate, and 200% (2 times) more bioavailable than the Orotate. The retention is also better at 300% (3 times) versus the gluconate and 50% more than the Orotate.
Studies carried out on Zinc are:
1. Vinson J.A., "Comparative Human Bioavailability of Zinc", Nutrient Availability Chemical and Biological Aspects, Royal Soc. Chem., 1989.
'The Zinc Yeast was more absorbed and retained than other forms of Zinc and is thus the form recommended for human consumption.'
2. Vinson J.A., "Zinc Bioavailability", Unpublished Data. I 988
The Zinc yeast was the most bioavailable form of Zinc in both the plasma and the liver.'
3. Vinson, LA., "Bioavailability of zinc", Unpublished Data, 1980.
'The Zinc yeast was more absorbed in blood and more retained in the liver than other forms of zinc.'

'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.'
5. 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.'
