You missed the point. Desicatted liver was a primitive supplement in the old days. I believe it stated 'started with desicatted liver.....'
And no, I HAVE NEVER seen or heard of a reaction to liver powder with many many guys taking it in large amounts at the gyms long before the more advanced supplements of current times! These days, I don't hear of anyone taking it. It seems whey powder is the HIGHLY marketed supplement of choice.
