Serrapeptase Side Effects


The proteolytic enzyme, serrapeptase, is taken to ease inflammation. This particular protease is used as it effectively dissolves dead and swollen tissue.

I first published information to the internet in 2000, after a San Diego pioneer first educated me on its properties. I researched 23 studies on this compound, and started to prescribe it to clients who were exhibiting comparable symptoms. Dosages were in the order of 10,000IU for patients who were taking part in the early studies, but varying mega dosages were administered to other clients. Intake was progressively increased, and I soon found out that the studies were correct, as it was working as well as what was indicated, with superior results at higher doses. I am now 67 and have been taking as much as 240,000IU for the last 13 years on a daily basis. I am convinced that my excellent health is partly as a result of using this product.

Doctors and other individuals have released information to the internet community based on my findings. A concern is that these reports express opinions about serrapeptase side effects, but are not based on any real life experiences. With hundreds of thousands of clients that I have helped giving me feedback, as well as my own experiences with the product, my opinions are solely based on the feedback from these clients. There were two claims by a couple of doctors in Japan that serrapeptase had caused a lung infection. This has not been duplicated from hundreds of thousands of users in the past twenty years and all I can surmise is that they were mistaken. It is not the first time in my experience that doctors were mistaken.

Serrapeptase seems to be safe to use for adults and children when consumed orally. Taking it several times a week, and then stopping will allow an individual to accurately assess its effects or effectiveness. 99.9% of my clients, as well as my children and other family members, have all reported no side effects. Long term effects have not had any formal documentation.

Warning: If you are in search of information about serrapeptase then ensure that the health care professional is well educated in the field of enzymes and how they play an important part in overall health.

Quite a few of my clients, as well as my daughters, were taking serrapeptase during their pregnancies, as well as during breastfeeding. Serrapeptase has been highly effective in women who have endured scar tissue inside their fallopian tubes. They were all able to have healthy pregnancies and babies, while taking serrapeptase with other supplements and using a carb-free diet.

Excessive bleeding: There are warnings that point out that serrapeptase can stop blood from clotting and exacerbate bleeding problems. The majority of these warnings are stated by people who are not aware of how this substance produces its results. My findings indicate that it does not cause unusual bleeding and the only cases reported were those who already had problems, e.g. with nose bleeds.

Usage during surgery: My personal recommendation is to stop the intake at least 24 hours before a surgery and continue when 24 to 48 hours have passed. This can help clear up any scar tissue, and stop lesions and adhesions from occurring.

Digestive system: Taking any proteases with a poor digestive system may cause discomfort or pain in certain individuals. Ingesting with a half teaspoon of bicarbonate in your 500ml glass of water may help to alleviate this. If you do experience continued pain from digestive problems then email me personally, and I will send you a plan for your digestive recovery before you continue with the use of serrapeptase.

Interactions with other drugs: Serrapeptase is safe to use with all drugs as well as warfarin, statins and aspirin.

    Hi there. I m wondering if serrapeptase would work for me. I had a son 2 1/2 years ago and have been trying to conceive since he was 9 months with no success. We were told that my tubes were blocked so I had tubal cannulation and my last hsg showed the dye went into the tubes but wouldn’t come out the ends(before cannulation dye wouldn’t even enter tubes) so now it seems there is still some sort of blockage where the dye won’t go through and out ends. Would this work for me? I should mention that in past I have had my colon removed and have a pouch internally now so is serrapeptase safe for intestines and pouches? These surgeries I had are over 20 year’s old. Was going to take serrapeptase along with xi sian cap and mi you cao

    I decided to try serrapeptase, starting today. My tubes are blocked and swollen. My doctor said the only way I can get pregnant is through ivf and of course my husband and I don’t have the money for it, this is my only hope. I had the surgery to open my tubes up and the closed back up, do you think taking serrapeptase will help me?

    Dear Doctor,
    I am a heavy smoker, I smoke 30 cigeretts a day, I don not have any health issues or problems with my lungs, I am saw in one blog that serrapeptase help repair/ build lungs. I started taking 10mg tab 20000 units, currently facing gastric trouble and pain in lower abdomen, I think its due to gas. Is it safe to take these tablets? Shall I continue? I hope Serrapeptas will clean my lungs. Thanks

    Hi Robert,

    I have Psoriatic Arthritis and have been working on it (alone) for some time with a cocktail of supplements including turmuric, fish oil, glucosamine etc. I have recently concentrated on healing my gut with digestive enzymes, acidophilus, aloe vera and glutamine… and SERRAPEPTAZE.

    Since I have added the gut-healing stuff and the serrapeptaze, I have noticed a marked improvement in my joint pain, in particular my swollen and painful ankle.

    Now my question is this. I only take 80,000 units a day. If I increase it, then my ankle hurts more instead of less. I have tried changing brands, but whenever I increase the dosage, even just to 120,000 a day, the problem returns. I have a feeling that the enteric coated brands increase the pain even more. What seems to work for me is 40,000 well before breakfast (at least 1 hour) and 40,000 at least 1 hour before dinner..

    Why can’t I increase the dose? Could it be that the serrapeptaze is clearing partially blocked veins and arteries in my left leg (they are 60% blocked in my right leg where the painful ankle is) and that is causing pain or a sort of herxheimer effect? Should I increase the dose and grin and bear the pain or should I stick to my present low dose?

    Many thanks in advance for your ideas.



    • Robert Redfern says:

      April 07, 2014 at 11:56 am

      Since this is an auto immune disease I don’t simply recommend basic Serrapeptase. You have a complex condition and I recommend BlockBusterAllclear or Serranol will product better results.

        Many thanks for the reply. Yes I was going to try Blockbuster, but you did not answer my question and that was: why do you think my ankle pain (etc) gets worse if I increase the dose of serrapeptase when you say that there are no side effects and you advocate quite high doses?

        • Robert Redfern says:

          April 09, 2014 at 05:07 am

          This is a great question as many people consider ‘side-effect’ in the wrong way. A side-effect is when something you take or do causes a problem that was not there before. EG you take something for your ankle pain and it give you a headache. That is a side-effect.
          It is not a great example as headaches can come as part of a detox effect. Simply stopping coffee can cause headaches but I hope you get my meaning on this.
          Digestive discomfort is the most common compliant when taking serrapeptase (albeit very rare). It is not caused by serrapeptase. it is simply revealed by serrapeptase. This discomfort is revealed by many things including eating the wrong foods.
          If you did some essential walking to keep your ankle working and got a pain you would not think of the resulting pain as a side-effect, you would consider it part of the healing process. You may adjust the exercise to limit pain but you would not stop.
          If your ankle not resolved with Serrapeptase and exercise then there is the ultimate solution, HealthPoint. See my video here

          You have a complicated condition and it could simply be your damaged ankle which is under tremendous pressure with you walking on it is still very acute. You may simply be walking on it too much after taking serrapeptase. Serrapeptase clears chronic inflammation (inflammation that is not acute) and inflamed dead tissue (a type of scarring). The serrapeptase does not heal the problem, it clears the way for your body to health it. If your body is under constant attack from your auto immune disease then it could be the serrapeptase on its own rather than with the other parts of an auto immune plan is stirring up the battle. I suggest a phone call for a longer discussion

I have had several steroid shots in my back and they do not give me much relief. My brother told me about serrapeptase and told me to give it a shot. I take one 40,000 pill a day. Can you please recommend a proper dose that may help the inflammation on my disks and my knee that may give me relief.

    i used a product for endometriosis called fibrovera. I only used it one month but discontinued use because i started another product called wobenzyme N. Both these products have enzymes. The fibrovera has both Nattokinase NSK and Serrapeptase in it. Im not sure if this started working or not because i used it only for one month, however i had an extremly heavy period following use, but i believe that was due to other circumstances. My question is- does the enzyme Serrapeptase and or Nattokinase NSK cause darkened urine or mostly orange urine intermittently (some days)? and does this mean that its possibly working and breaking down fibrin from endometriosis>?

My son’s been taking it twice a day for 2 days, and I wish I coulde say he’s getting better, but today he said the pain is worse. He hasnt done anything different than he normaly does. Is this a possible side effect, or should we give it a bit more time.

    I am pregnant and was prescribed to take serratia which is pure serrapeptase. I am told to use this for better circulation. I am an incredibly nutritional/clean eater. And overall pretty healthy. What dosage would you suggest per day? Thanks.

    • Robert Redfern says:

      March 21, 2014 at 05:23 am

      Firstly, Serratia is serrapeptase and all serrapeptase is the same since it all come from one manufacturer in India. To claim theirs is more pure is deception marketing in my opinion. Only the strength, the capsule and extra ingredients can vary. Even then they may be deceiving customer as they claim theirs is the strongest and best value but their strongest cap is only 125,000 and their 250,000 dose nearly twice the price compared to my 250,000iu caps
      It is fine to take serrapeptase while preganant to help circulation and other problems that arrive. I recommend a maximum in my ferilty plan of 80,000 caps – 2 x 3 times per day and dropping to 1 x 3 if everything is fine The plan is here

I have a lot of swelling and scar tissue already around and probably under the kneecap. Would serrapeptase help me dissolve this scar tissue?

      Studies show that taking statins makes no difference to your life span. What will make a difference is your diet. Stopping carbs and high sugar foods will help your body to heal. Eating fresh foods and drinking 6 glasses of water is the best things you can do.
      BlockBusterAllclear 2 caps x 4 times per day, 30mins before each meal and the last 2 at bedtime will help your arteries.

    Hi Robert:
    I have started serrapeptase for fibrin issues and heart block. Initially, (2 days in) I felt great, but upped the dose (from 3 40,000 to 3 80,000 in divided doses) and have been experiencing some muscle aches that were not present before. Theoretically I can imagine that the breaking up of unwanted tissue can present some problems/inflammation. Are you aware if this is something that will dissipate with time? For the time being, I am backing off on the higher dosage to check symptoms. Any info/thoughts would be most appreciated!

      The amount at 240,000 per day is not too much as many people take 2,000,000 per day
      Are you drinking 6 x 500ml glasses of water over each day?

    Hi I was wondering g is it ok to take Serrapeptase while trying to conceive? We were told my left tube is blocked from scar tissue from two years ago. If it is ok which of the products would be the one to use?

    • Robert Redfern says:

      March 04, 2014 at 01:22 pm

      It is very successful for clearing scarred and blocked tubes.
      Take SerraPlus+ 1 cap x 4 times over the day
      also Nascent Iodine drops 4 drops in 25ml of water x 4 times over each day
      I also have a fertility plan a

    My husband is 78 and has just had an angiogram due to blocked arteries about 2 weeks ago. He is diabetic and is on the following drugs: warfarin, symbicort 200/6 turbohaler, ADCAL D3, metformin, Novomix Insulin, amlopidine, aspirin, atorvastatin, clopidogrel, digoxin, furosemide, gyceryl trinitrate (pump for angina), prednisolone 7.5mg. I was impressed by your article on serrapeptase enzyme. I am wondering if you think he will benefit from serrapeptase. If so could you advise me and maybe he can start on them

    You claim this product is safe and effective yet there are negative reviews on where people claim this enzyme has resulted in heart damage and has made their condition worse. People on amazon has reported some serious side effects such as damage to purkinje fibres, and fibroid tissues growing in size. Why would u reccomend such a dangerous enzyme?

    • Robert Redfern says:

      February 23, 2014 at 02:13 pm

      Through this website, my book ‘TheMiracleEnzyme’ and my newsletters, that have had millions of readers and users of serrapeptase over the past 15 years since I introduced Serrapeptase, I have not had one serious so called side-effects from serrapeptase. Yes, a few have said it made a pre-existing digestive problems react but eating the wrong food can do the same thing.
      The things you refer to in your question posted on Amazon are so ridiculaous as to be laughable. You must realize there are ‘nut-cases’ as we call them in the UK who will say anything if they have the chance to get their name on the internet. You cannot tell me you believe every crazy fool (and I include certain doctors in this) who types something on the internet just to be noticed.
      When I first started recomming serrapeptase it was 10,000iu doses and over the past 15 years as the safety of higher doses has been shown to by OK I am now recommending SerraEnzyme 250,000iu caps for even better results.
      If you see any other such crazy reports on the web be sure to come and tell me so I can refute them as well as this one.
      I really appreciate your time in this.

    It is hard to say as bursitis is one of the hardest next to calcium spurs to clear.

    I suggest SerraEnzyme 250,000iu 2 caps x 4 times per day for a couple of weeks
    Also importantly:
    6 x 500ml glasses of water over the day with a 1/3rd teaspoon of bicarbonate of soda in each glass.

    I have been taking serretia serrapeptase once a day for a week. The dosage is 250, 000 spus..I started taking this because I have uterine fibroids and wanted an alternative to surgery. .I have started having spotting though and wonder is it because it is working and breaking up the fibroids or if I should be concerned

    • Robert Redfern says:

      February 20, 2014 at 07:58 pm

      It is not a major concern but you should be also taking Nascent Iodine drops as well as selenium.

    This is the 4th time with blood clots. Ultrasound revealed 80% blockage in right leg all the way up to thigh. I’m on 80mg Lovenox injections twice a day for 20 days and then 7mg of Coumadin. I do fine with the injections and the swelling has gone down. I do not want to start the Coumadin ever again as it caused me severe intestinal bleeding, 30lb. weight loss and all loss of bowels. Was able to survive and don’t want to relieve this nightmare again. I am working Natto-K into my daily routine but would the serrapeptase be better? Helma

    • Robert Redfern says:

      February 15, 2014 at 06:55 pm

      BlockBusterAllclear would be better. Take 2 caps x 4 times per day, 30 mins before each meal and the lasy 2 at bedtime.
      Do this for a few weeks and then try halfing the dose to get the same good results.

    I’m a bit confused but maybe it’s because I’ve read so much already and maybe too fast, on one page I thought it said to use Serrapeptase for RA but then in one of the above replies you told someone that it’s not for autoimmune but isn’t that what RA is??

    • Robert Redfern says:

      February 15, 2014 at 07:07 pm

      Serrapeptase in high doses EG SerraEnzyme 250,000iu 4-8 caps per day will give you relief.

    Hi Robert

    I am going to begin taking Serrapeptase 40,000 iu because I heard it was good for lung rejuvention. I presently have enphysema. I also statred taking NAC. My only concern is that I had a heart attack in 2005 (8 yrs, ago) and they tried clotbusters on me. (which didn’t work). I have 3 stents and no heart damage at all. Serrapeptase is not like a clot buster is it? Bcause I was told once you have had this :clotbuster procedure, you can never have it again.

    My daughter has a uterine fibroid which causes a lot of pain most of the time which the doctor has put her on volteran to get through the day. Is it possible to wean her off the volteran while taking serrapeptase. Also she is trying to conceive. The fibroid is not a large one, but she is always cramping and has the occasional diarrhea usually middle of the month and with her period. She takes vitex supplement.

    Hi..I am 43 and had a stroke Jan 2012. My right cerebral artery was completely obstructed. At the time, I didn’t have a clue that I was having a stroke, no symptoms other thn lower left leg weakness, which I thought was overuse at gym. My LDL was 56, HDL 66. Tryglycer under 100. BP avg 117/76. The past 10 yrs, My diet includes fresh raw & steamed veggies, fruits, legumes, lentils, salmon, nuts, soy, Greek yogurt, almond milk, pearl barley, oat bran, quinoa, egg whites, almond butter. i use coconut oil & extra virgin olive oil for food prep. I never fry, nor add salt, just herbs & spices. i rarely eat chicken or turkey. Close to never any processed or packaged frozen foods. The only bread I eat, when I do is sprouted grain( Ezekiel 4:9). I work out 5-6 days a week.. 3 days weights.
    Growing up, I was very overweight. 10 years ago I changed to the healthier diet & excersised, resulting in a 90 lb weight loss, on my own.
    Md thinks it may be atherosclerosis from the past, but unsure. The residual effect from the stroke is mild weakness & numbness in left lower extremity & toes. Initially I developed foot drop, but cleared up 2 months thru excersise. It took nearly a year to wear high heels comfortably and jog. I want to dissolve this artery obstruction, what are your recommendations? Thank you for your time.

I currently present with an enlarged uterus, multiple fibroids and an umbilical hernia. I am a diabetic too. Am considering using both serrapeptase and DMSO for my ascites.

    Hello sir,

    I came across your site while searching to learn if it is ok to be a light drinker (1-2 drinks per day) while taking serrapeptase. I’m 42, I have chronic knee and back pain, as well as foot pain. It seems that you have plans for various things that people suffer from. Aside from the aches in my knees, back, neck, and feet, I just generally feel some aging happening ahead of schedule. any thoughts or advice? I also take eggshell membrane with naturally occurring elements for my knees. Any certain product recommendations? Thanks for caring.


  • Matt says:

    March 28, 2013 at 03:47 am

    I’m looking for an alternative to NSAID’s to reduce inflammation and pain. I have a knee that I’m told will likely require a full replacement, and a sore foot that the best anyone can say is because of the knee issues. Other than an occasional (every few weeks) Ibuprofen to get through a bad day, I’ve so far avoided taking any form of pain killer or anti-inflammatory. However it’s getting to the point where I’m in some pain every day and experiencing muscle weakness in my lower leg that more frequently is making it hard to walk at times or do a cardio workout on an elliptical machine. So I think I’m to the point where I need to take something. The earliest I can expect to have a knee replacement is 4 months or more away. Is serrapeptase likely to provide a reduction in inflammation of the joint(s) that will relieve some of these symptoms (muscle weakness) and/or provide pain relief? If so, at what dosage? I’ve seen a recommendation to not exceed 40,000IU. Is that enough?
