Potent proteolytic enzyme


Serrapeptase 125

Serrapeptidase or serratiopeptidase is a proteolytic enzyme, which means that it breaks down proteins into amino acids that our bodies can absorb and use. It is found in Japanese silkworms, and has been used in Japan for decades to treat ailments such as inflammation, pain management and respiratory issues. When taken on an empty stomach, Serrapeptase has the ability to pass through the GI tract without being compromised, and affect the thickness of mucus, which can be beneficial when dealing with respiratory infections such as the flu, or chronic respiratory diseases.

"I have just started taking the serrapeptase this week and am extremely happy. Most other supplements I cannot take on an empty stomach (I get nausea and often vomiting when I do); I have had no GI upset with Melanie's product at all…. I have now been taking your serrapeptase for around 3 weeks. I have noticed my skin has been clearer and also much less allergy symptoms (congestion, runny nose)"

So I took my first pill this morning. After fasting for about 16 hours. Oh my goodness, I can’t get over how easy I could breathe through my nose. I don’t have any nasal blockage or problems but wow, all of a sudden I could breathe through my nose with so much ease. Also, I do not know if it’s related but I lasted through my fast much longer than normal. Went to 21 hours when usually I go 18. Have no idea if that had an effect. I hope this continues and I fully appreciate total transparency Melanie uses and I think that’s why everybody trusts her so much. Thank you for your time.

"I've been using this Serrapeptase for about a month now and I couldn't be happier. From the very first day I experienced clearing in my sinuses and brain fog. I've tried other brands in the past and either didn't notice much change or felt like there were more fillers than actual serrapeptase. I discovered Melanie Avalon 2 years ago. She has changed my life in many ways, to become more healthy and this supplement is no exception. I know I can trust her methodical approach and refusal to settle for anything that will have a negative impact on her audience."

Loving how well it works!

Went to a subscription after the first order since I realized I could actually use just one dose. Two of us take this supplement and we both switched from another brand when we realized we only needed one dose for it to be effective. I was taking two doses of the previous brand and my SO was taking two and a half. Well worth the price!

Skip triggers a shipment.

I’ve had trouble, especially serapeptase, when I skipped a shipment I ended up with an additional shipment and it happened again. I now have several bottles and huge bills. Please look at your programming. I believe the same thing happened with Magnesium 8 too. Please fix.

Makes a difference

I ran out of this supplement a couple of weeks ago and I really tell a difference as far as inflammation and sinuses.

Jan M. (Cashmere, US)

My son opened our eyes to the possibility that the dead protein Amayloids could be helped with Searapeptase. Since docs say there is no cure, we seem to see noticeable improvements for my husband. We are thankful.

Sinus relief

This product is incredible. After decades of sinus congestion, this product gave me relief. Easy to take and digest. Bonus points for the glass bottle to minimize microplastics. I can absolutely tell when I have a missed a couple of days, and try very hard not to. Melanie was very particular when creating this supplement, and I am grateful.
