Anyone have info re: Knox Gelatin and whether or not it is paleo compliant? My understanding is that gelatin is made from hooves, cartalidge, etc., but am not certain if any soy by-products are added as well.  Knox did not respond to my product inquiries.  I'm would like to add 2 oz per day dissolved in water to see if it eases my knee pain.  I eat daily sardines + salmon and tuna several times per week and am not certain that I would like to start mega doses of fish oil (I have in the past using Eskimo-3 brand, but am concerned about the lipid peroxidation factor).
