Great product and great service from iHerb

Posted by Reviewer2513310 on Nov 21, 2009

Haven't used very long, but does not seem to irritate stomach as so many other enzyme products do. Enteric coating probably a big plus.

Really like the double strength

Posted by Reviewer1056499 on May 30, 2010

But iHerb was out of those so I purchased these until the double strength came back in. These are great enzymes.

Good supplement

Posted by Reviewer1019614 on Mar 24, 2009

I used the sample sent to me and noticed good pain relief qualities. I took 1 ibuprofen 30 mins. after Zymactive and the combo stopped a migraine dead in its tracks within the hour. Seems to boost effects of other supplements or medications. Will consider purchasing.

smell bad

Posted by Reviewer3079758 on Aug 23, 2011

Maybe these work, but the smell is so off-putting I will not buy them again. They make the whole cabinet they are stored in smell like cat pee.

Havent always directly noticed a difference, I take other anti inflammatory sups. But good co and ingredients, just need to take often and is pricey, but all of these are, this one is a better buy.

Too early to tell. No difference in my inflammation yet but also I should have gotten the double strength
