Serrapeptase by Doctor's Best is a proteolytic enzyme isolated from the non-pathogenic bacteria Serratia species found in the digestive tract of the Japanese silkworm. The enzyme is used by the worms to digest their cocoons. Serrapeptase has been used as a nutritional supplement in Europe and Asia for nearly three decades. Each vegetarian capsule is formulated with Serrateric™, an alternative to enteric coating designed for optimal absorption in the intestinal tract. Vegan, non-GMO and gluten free.

Serrapeptase is rated 4.5 out of 5 by 15.
Rated 5 out of 5 by from Why I purchase Serapeptas I reviewed claims made about the product so I tried it. It worked for me. Found over 500 revviews for this product on Amazon. Very few complaints. Swanson carries it I buy it here.

Rated 5 out of 5 by from So far so good These really seemed to make a difference the first month of taking them. Remembering to take them away from food is the hardest part. Great price!

Rated 4 out of 5 by from Good Product I was recommended to take this supplement. Wish Swanson had it in liquid gel capsules as I was told this was the best form to take this in. I got the capsules, which I think is better than tablets. Not sure how good it's working yet, but I think any is better than nothing so trying it this way.

Rated 5 out of 5 by from Enteric-coated on empty stomach is important Enteric-coated is essential for stomach acid to not destroy enzymatic properties, as enzymes are protein and the stomach will destroy its properties when digested UNLESS the enteric-coated supplement by-passes to the small intestines. Dr Best is why I get their product, along with enteric-coated nattokinase. I take 5-6 Wobenzym (German formula), 2 Serrapeptase and 2 Dr's Best enteric-coated nattokinase tablets on empty stomach for systemic enzymatic therapy. Plenty of info online for this therapeutic approach, check it out.

Rated 5 out of 5 by from Life Changing... Wish I could say what I really wanted to say..But this enzyme is remarkable. If you are thinking of using it Please don't hesitate. My aunt took this at 120,000se 2x per day for a few months and now she is so glad she did. She has a new lease on life and is telling everyone who will listen what a change that has taken place. Dr's Best works extremely well and for the price you can't go wrong. Does not upset the stomach and works quickly. And I can't say enough that it is such a great value for such and effective product. Thanks Swanson for high quality products that are easy on the pockets!

Rated 5 out of 5 by from EXCELLENT This product works GREAT. I tried other brands of but then came back to this brand permanently. It is good for a whole slew of different things and is easy on the stomach lining. Do a SEARCH on Serrapeptase to see the different benefits of taking this capsule.

Rated 5 out of 5 by from Good product My family and myself has been using this for over a year on and off. We will not do without it and the price is good at Swansons

Rated 4 out of 5 by from Great product Better than anything else I've taken. I can not go without this product. I surely wish I could go into details.

Rated 5 out of 5 by from Doctor's Best Serrapeptase It is a very good price for this enzyme. Way cheaper than Vitalzym :) I take this on empty stomach away from food. And I feel good taking this with other digestive enzymes I ordered from Swanson. What I like about this brand is that it does not contain any questionable fillers. I will be ordering it again.

Rated 5 out of 5 by from Doctors BEST Serrapeptase Brand is the best! I started out with Doctors Best brand of serrapeptase and had great results with my joints...then switched to Solaray - big mistake... Promptly, switched back to Doctors Best! This is the brand, that works for me (= BTW -- For best results, I take on an empty stomach in AM, and wait @ 1/2 hr. befoe eating.

Rated 5 out of 5 by from FANTASTIC This product has changed my life. The enteric coating is absolutely essential to the efficiency of serrapeptase, and Dr's Best has it. I can't recommend this product highly enough.

Rated 1 out of 5 by from Didn't Do the Job I first starting taking Serrapeptase using the Solaray Brand and that worked very well. I thought I would look for a better value and tried Doctor's Best. I don't kow why but this brand had no helpful effect for me. I had to switch back to the Solaray brand.
