[QUOTE="cjmc, post: 1501744, member: 27842"] Sulfates are not 100% Bioavailabile. They have a 100% "relative bioavailability" rating. Actual bioavailability is pretty low. They have a 100% rating because those forms of mineral were what was used in the orignial research to determine the requirimed amount and they became the standard to what other forms of mineral are now compared to. For instance the aforementioned Zinpro minerals are a higher quality than sulfates. I believe their bioavailability is listed at something like 125-150% (it varies depending on if your are talking about Cu, Zn, or Mn) that obviously doesn't mean they absorb more mineral than they ate, it just means they absorbed 25-50% more when compared to the sulfates and thus are a higher quality product.
