Serrapeptase 240,000 SPU Max Potency (120 Veggie Capsules) Proteolytic Enzyme for Sinus, Respiratory and Joint Health (Non-GMO, Gluten Free, Vegetarian Safe) by Double Wood

It seems to work fine for me and less expensive than the one I used to use! Almost 10 years I've been using Serrapeptase for mucus in my lungs--lifesaver! Helps me not to cough at work! 👍💜

I know it’s legit because although I normally take it between meals for it’s anti inflammatory properties I will also take it with larger meals and notice a drastic improvement in digestion.

Why did you pick this product vs others?:I take two capsules on an empty stomach every morning. My sinuses stay clear as long as I take this enzyme supplement. The last time I ran out I began to have difficulty breathing through my nose affecting my sleep. This brand of supplements seems to be good quality and I usually choose double wood over other brands.

USE IT TO REDUCE CHRONIC CONGESTION IN MY CAT'S LUNGS. REDUCES THE COUGHING A LOT. NOT CURE BUT IT LIFTS HER SPIRITS. IT IS AN ENZYME THAT IN THE BODY BREAKS DOWN INTO AMINO ACIDS.

I've been taking Serrapeptase 240,000 SPU for a while to help with my sinus issues. While I haven’t noticed any major improvements yet, the good thing is that I haven’t experienced any side effects either. It’s gentle on my system, and I’ll keep taking it for a bit longer to see if it helps over time. It seems like a safe option if you're looking for a natural enzyme supplement, but results may take a while.

I've been taking this for over a year & I like it, though it may not be for what it's supposed to be for.

A very good product and consistent

I had so much stomach pain and diarrhea .. I had to stop taking it . Wasn’t should of that’s normal for the first time using it
