Is serra peptase better for your stomach or other organs than Aleve (naproxen) or ibuprophen?

Yes. Not sure how effective it is compared to other anti inflammatories, not enough research done to show its side effects and benefits. Go on raysahelian.Com and see what dr. Sahelian says about it. Ive personally read a lot of his suggestions and he's an excellent alternative medicine doctor. No GI side effects that i know of.
Not necessarily. According to the natural medicine comprehensive database, the product is likely safe, but insufficient data re: effectiveness for any of the purported benefits. It may interact with medicines and herbals that can interfere with blood clotting.
