Serrapeptase (serratio-peptidase) is a protein-digesting enzyme isolated from the friendly bacterium Serratia E-15 discovered in the Japanese silkworm. Doctor’ s Best High Potency Serrapeptase is formulated with Serrateric, a superior alternative to enteric coating that protects the individual enzyme until it reaches the intestine for optimal absorption.

Review: Truly amazing. I am taking this along with Xi Xian ... - im on day 5 ; on day one I noticed an improvement in my left thumb joint that over 6 months of physical therapy has not achieved. I actually was able to bend my thumb from zero degres to 10 degrees. not much you may say but it is huge for me. In my l eft kee where my mobility has been extremely limited an I wa unable to bend my knee for over a year. then I started working out/ stretching and got it to aboutkn 20 percent of a bend with this on day 5 I bend my knee to a 90 degree angle perpendicular to the floor!!!!! Truly amazing. I am taking this along with Xi Xian Cao 1/8 tsp with water once a day.***UPDATE*** my XI XIAN CAO finally arrived and now I am taking this with it as well. I scoop which is provided as well as 1/4 tsp of the Xi XIan. Once a day. I take the two tea products and shake in a 8 ounce bottle of water. If you let it sit for a while it will combine together and taste like unsweetened tea. Not bitter when taken together . I stopped taking it for two day and severe pain returned throughout my body. During the first few days I slept a lot but it may not be related. I will work up to the three times a day metioned as my goal is to decrease scarring in my fallopian tubes and uterus etc. I also noticed on day 5 My skin on my face crumbled off like dry skin so I took a bath and revealed a fresh new skin; It is truly amazig that it goes deep down to your skin. My c section scar is already looking improved. Shockingly I went to wipe off the dry looking skin during my first day after I stoped taking it and resumed and noticed one of my Im liver spots on my face fall off! It is amazing. My feet feel like they have glass in it as it has in the past but i detect healing this time.I have some type of yeast or something that causes this severe pain in my feet but it feels like my body is trying to push this out as well. This product works quickly. I amazed at all the good results in such a short time. I am taking one capsules once a day as soon as I wake up with a glass of water and then I wait two or three hours before I eat. Negatives: I have noticed it does make me feel a bit nauseous and maybe sick to my stomach for a few hours after I am taking it. This may be due to all the stuff it has to get rid of in my body. This works faster than Wobenzymes. I have decided to take them along with those though for a better result. I will update after more time has gone by I have seen reviews like "IT worked" but that does not give me any information as to what the person felt it worked on or what they expected it to do. I was only expecting some reduction in my fallopian scar tissue but then when I researched more and found out it can clear out the arteries of plaque etc. then I am hoping for that as well. I have not cut myself yet but the bottle does ay it is good for clearing out the sinuses. I have notices a thinning of my vaginal cervical mucous which is huge for me. I am no longer dry down there! That is such a plus. On day 2 I noticed pain in my legs deep into my muscles and veins it was like a cramp that would start and stop like a heartbeat but after taking the tea at night time this stopped and is not a problem. Ive noticed pain in my kidneys as well and have peed strong urine smell pee with white pieces of tissue. this is also easing up. I can't believe how many things this is working on and how much of a mess my body has been in! Im hoping to get stronger so I wont need as many pain pills from the doctor.. Strong pee still but also stringy stuff coming from the skin of my labia.I cleaned that up. I will continue to update. It is worth getting all three products and taking them together. My deep stomach pain has now resided. had some increased energy today and did not need to sleep like the other days. This stuff all together is amazing.
Review: A near perfect way of managing and preventing many conditions - I first learned about this wonderful enzyme while researching ways to manage stage IV endometriosis post surgery, i.e. w/o hormone injections. Since I pretty much followed endo diet anyway (no soy, red meat, farmed protein, gluten free, etc.) I needed a way to fight this monster. Adding serrapeptase has been superb. I also noticed that if I took it with food it acted as a great enzyme for digestion. My lessons learned, I continue to reap benefits and would like to share what this has done for our family pets. IN these cases, it's not about pain management but rather - their food intake and waste removal. As an animal lover and an owner of a very senior pet with early stages of renal disease and an overactive thyroid I am always trying to prevent his kidney issues from resulting in megacolon and general constipation. He is fed holistic diet but is also very picky. He also has issues with his hips from some nerve damage done when he had Perineal urethrostomy some 12 years ago (ugh... a sex change to prevent life-threatening blockage), plus the dude's getting older (now 17!). Recently he's really started slowing down and I took a wild guess that he, like many older cats, simply was not absorbing nutrition as he should from what he does eat and when he does not things also get clogged (he eats wet with a little dry as a treat). His thyrioid med is great but something still wasn't clicking and reality started to hit that he may not be around for more than a year or two. After a particularly troubling poop-less period(forgive me here, but as a pet parent you know the importance of it) three weeks ago I threw caution to the wind. My boy began to look more fragile than usual and not as determined not to act his age. His soft fur lost luster and, as all senior pets do, looked frail. I thought, screw it, what do we have to lose? I started mixing in 120K units of serrapeptase directly into the top of his food with hopes that he would eat at least 80K units. His dry spell continued for a day and then I was presented with double (perfect) 'output'. After that, over each day his appetite returned, he produced great regular 'product' which looked nothing like he created even on his 'good' days, there was less smell among other things and no strain on his part. His whole demeanor changed for the better. His vet mentioned that not only do older cats have trouble with nutrient absorption but also often run into issues with arthritis and sometimes even temporary paralysis because they strain so much. With this only change in his otherwise flawless diet and cold pressed grizzly brand salmon oil he is a new creature. He's shed years - he is relaxed, playful, his appetite returned, he is walking more comfortably and overall his quality of life clearly changed w/in a few days. I cannot believe the transformation. My family talks nutrition the way some follow sports and are well versed in holistic pet care. Still, each animal reacts differently and they are aging. Coincidentally, my parents were at their wits end fearing the end of their own 17 year old cat. As they braced for another miserable last-ditch visit ($$$ & stressful for Charlie) to the vet whose only solution so far has been to put him under, clean him out and send him home with lactulose. SO far they thought they were lucky - he does eat organic raw pumpkin and a few other helpful goodies. Still, after the terrible paralisys episode a few weeks ago and an unusually bad (lack) of recovery the were heartbroken. In desperation (just before the vet visit) they mixed in contents of a 40K capsule into his lactulose and gave it to him with his two doses. It took a day for him to finally go, but once he cleared his system it's been the same type of recovery as I've seen in my own guy. Four days later my mother is shocked at his overall change just as I described in my dude. Clearly, the normal way of taking it is on an empty stomach and for pain. I simply used the logic that this is still a strong digestive enzyme as many other sources described. It made sense but my parents and I can testify that the positive effect it's had on our senior boys. I'm adding Zeel (from Traumeel Heel makers) for pain just in case but will continue to use serrapeptase for my creature as a hidden topping on his food. My guess is that he's getting about 60K with each meal and that seems to suit very well. I look at photographs I took of my pet three weeks ago and those taken over the last week and he looks several years younger, well hydrated and clearly unburdened by any discomfort. This was the only thing added to Mo's routine. There are many enzymes one may add like protease but this was already in my kitchen and there was no need to jump through hoops. I urge those who have arthritic pets to follow our lead and help their furry kids strain less and enjoy their senior years in peace. Right now, I'm hoping for another five good years with my creature. Who knows? BTW - I buy this product from desertcart or Vitacost interchangably. I do not use the enteric capsule and set is aside for other use. I hope those struggling with their aging pet's digestive issues may consider our experiences and give it a shot. I would also like to point out that the little jelly glops from pollen allergies are gone too. He eats food w/o soy, animal bi-products, w/gluten already.

## Questions & Answers

**Q: Is the enteric coating made with HPMCP ---- phthalates?**
A: a superior, all-natural, vegetable based alternative to enteric coating.  This is the statement made regarding the coating on their products.  This product came highly recommended and my results have been amazing.  Sorry, that is the best answer I have without researching with the manufacturer.

**Q: Can I create a poultice to help reduce keloid scarring?**
A: You do not need to make a poultice! I had a big ugly keloid scar on my chest. It was a pinkish red color and you could see it through my shirts and blouses because it created a lump under my shirts. I started taking this and it is now flat and white. Always take it on an empty stomach and always take it with lots of water. You need to stay well hydrated while taking this. But you might as well take it internally and get the other benefits. I don't know about making a poultice out of it...hadn't thought of that. I was taking it for my heart and had no idea it would do that to my scar!!

**Q: The bottle says one severin (1-pill) has 120,000 serratiopeptidase units. Does anyone know what this would be in milligrams??**
A: 10 mg equal 20,000 spu so 120,000 is 60 mg. Sixty mg is too high a dose for many people and the suggested dose in most scientific studies is 10 mg three times a day on an empty stomach or about 2 hours after a meal. SO I myself caught your question and thought I'd answer. Since yes it's 2014 question it is still relavant today. Stay safe everyone. And use supplements wisely.

**Q: What is serrapeptase used for?**
A: I started using serrapeptase to help with chest congestion from chronic bronchitis.  The congestion was better within a few hours and the inflammation and tightness started to go away within a few days.  It also helps to dissolve scar tissue and adhesions from surgeries and injuries.
