Just got home from my holistic doc and he was telling me that Zypan from standard process produces enough stomach acid to digest meat and fish so we dont get worms from these foods..I have been taking for a few yrs but had no clue it would keep you from getting worms from meat...Many of you may know about this already. Just thought i would mention it for those who dont know.There may be other digestive aids to that work as well...I get Zypan on Amazon if interested.....I take anywhere between 4-6 per meal,depending on meal size..
