Serrapeptase, also known as serratiopeptidase, serratia peptidase, or silk worm enzyme, is an isolated enzyme from bacteria found in silk worms. Mostly used by health care professionals in Japan and Europe for reducing inflammation after trauma, surgery, or in other inflammatory circumstances, it is also available as a dietary supplement for its various health benefits. This article will explore the science behind those health claims, discuss the potential side effects of serrapeptase, and help you decide whether this anti-inflammatory is right for you.
What Is Serrapeptase?
The serrapeptase enzyme is a proteolytic enzyme, which means it has the ability to break down proteins into their building blocks, amino acids. It's an enzyme produced by the bacteria living in the silk worm's digestive tract, and specifically it's the enzyme that allows an emerging moth to dissolve and digest its own cocoon. If you're the kind of person who finds bugs and worms to be skin-crawlingly gross, it might do you well to think less about where this enzyme comes from, and more about what it and other proteolytic enzymes like bromelain, chymotrypsin, and trypsin can do to benefit you.
Discovered throughout the 1950s, these enzymes were used in the United States to relieve the inflammation caused by ulcerative colitis, rheumatoid arthritis, and post-surgical swelling. By 1957, the Japanese were using serrapeptase in the same manner, and in the 1990s these different enzymes were compared and it was found that serrapeptase was the most successful at reducing inflammatory responses. Since then it has become more widely used in Europe and Japan for its anti-inflammatory benefits.
The Benefits of Serrapeptase
Though serrapeptase is relatively new to the medicinal scene, there have nevertheless been many studies done to document its effectiveness and safety. Here are some of the benefits that have been observed from the use of serrapeptase.
May Reduce Inflammation
This is the health benefit serrapeptase is best known for, reducing inflammation in instances like tooth removal or post-surgery recovery. It's thought that serrapeptase works by decreasing inflammatory cells at the site of injury. The anti-inflammatory effects of serrapeptase were shown in a clinical trial on the surgical removal of wisdom teeth, and serrapeptase was found to be more effective at improving lockjaw than more powerful drugs like ibuprofen and corticosteroids.
Though corticosteroids improved facial swelling more effectively on the first day post-surgery, the differences on the second day were insignificant. While more research is still needed to define the best uses of serrapeptase going forward, the researchers in the study did note that serrapeptase had a better safety profile than the other drugs analyzed, which may make it particularly useful in cases of drug intolerance in patients, or those who have adverse side effects with stronger drugs.
May Prevent Infections
There is evidence that serrapeptase may decrease the risk of bacterial infection by acting as a "biofilm buster," so-called because bacteria have the ability to join together and form a protective barrier or film around themselves. The biofilm shields them from antibiotics long enough that their rapid growth can take place and cause infection. Serrapeptase can inhibit the formation of biofilms, increasing the efficacy of antibiotics in cases like Staphylococcus aureus (Staph. aureus), or staph infection, one of the most common opportunistic dangers associated with hospital stays.
Both animal and test-tube studies have shown that serrapeptase combined with antibiotics was more effective than treating Staph. aureus with antibiotics alone, including those strains that have become drug-resistant. An example of a drug-resistant form of staph infection is MRSA (methicillin resistant Staph. aureus), an especially dangerous infection to those who are already hospitalized in immune-compromised states.
May Reduce Pain
Pain being a symptom of inflammation, serrapeptase has been known to reduce pain by inhibiting certain compounds. For example, in one double-blind study that examined the effects of serrapeptase in about 200 people with inflammatory conditions of the ear, nose, and throat, researchers found that those who took a serrapeptase supplement had significant reductions in mucus production and pain severity than did those who took a placebo.
Another study found that serrapeptase reduced pain significantly compared to a placebo in 24 participants following the removal of their wisdom teeth. More research is needed for scientists to be sure of serrapeptase's effects, but these findings show promise for those hoping to avoid nonsteroidal anti-inflammatory drugs (NSAIDs) after medical procedures.
May Help Dissolve Blood Clots
It is thought that by acting to break down fibrin (a protein formed in blood clots) as well as damaged and dead tissue, the serrapeptase enzyme could help treat atherosclerosis. Atherosclerosis involves plaque buildup inside your arteries, which leads to a hardening and narrowing of the arteries and an increased danger from blood clots.
If serrapeptase is successful at dissolving plaque or blood clots, it could reduce a person's risk of stroke or heart attack. However, not enough studies have been done showing a direct effect, and so while there is potential that serrapeptase has a role in treating blood clots, more research is warranted.
May Be an Aid Against Chronic Respiratory Disease
Chronic respiratory and chronic airway diseases affect the lungs and breathing apparatuses of the body. Serrapeptase's potential to clear mucus and reduce inflammation in the the lungs could help improve breathing in those with asthma, chronic obstructive pulmonary disease (COPD), and pulmonary hypertension, which is a form of high blood pressure in the vessels of your lungs.
These chronic conditions are ongoing and incurable, and yet managing the symptoms effectively (as with increased mucus clearance and better dilation of air passages) can greatly improve a person's quality of life. One month-long study of 29 participants with chronic bronchitis involved a test group that was given 30 milligrams of serrapeptase per day, which resulted in less mucus production than the control group, better lung-clearing ability, and greater ease of breathing.
May Treat Endometriosis
Due to the potential serrapeptase has for targeting dead tissue and scar tissue throughout the body, some believe there is potential in using serrapeptase for endometriosis treatment. Endometriosis occurs when endometrial cells grow outside the uterus, in the tissues surrounding the pelvic area, causing pain and often issues with fertility.
Likewise with conception issues arising due to ovarian or uterine cysts, serrapeptase for fertility is another natural therapy that currently has more anecdotal evidence than scientific research done on it, though that does not mean the research won't be done, nor that it wouldn't be a safe supplement to try in consultation with a qualified health care professional.
May Help Relieve Alzheimer's Disease
One study on rat models revealed that the proteolytic enzymes nattokinase and serrapeptase may have a therapeutic application in the treatment of Alzheimer's disease, modulating the different factors that characterize the disease. Oral application of these enzymes provided a decrease in transforming growth factor, acetylcholinesterase activity, and interleukin-6, all of which are found in high levels among patients with Alzheimer's disease. While more research still needs to be done, Alzheimer's is a medical condition that needs any relief options available.
Potential Serrapeptase Side Effects
Because it's such a new commodity, people are rightly concerned that there could be potential serrapeptase dangers. There are not many published studies touching on potential adverse reactions to taking serrapeptase, however some studies have reported the following side effects.
- Stomach pain
- Disturbances to blood clotting
- Muscle/joint pain
- Poor appetite
- Skin reaction
As there is a lack of data on the long-term safety and tolerability of this enzyme, should any side effect occur after you take it, you should stop immediately and seek medical advice. What works for some may not work for all, and so your judgement is paramount when it comes to whether you're getting the benefits you want.
How to Take Serrapeptase
It's advised against taking serrapeptase with any sort of blood thinner, or other dietary supplements like turmeric, garlic, or fish oil which could increase a risk of bruising or bleeding. For serrapeptase dosage, it's recommended to take between 10-60 milligrams per day (the range used within the various studies) on an empty stomach, and to avoid eating for at least 30 minutes afterwards.
When purchasing the supplement, choose a product in an enteric-coated capsule to prevent your stomach acid from neutralizing the enzyme before it reaches your intestine. Without a strong enough capsule, the enzymatic activity could be deactivated before it has a chance to work.
How long does it take serrapeptase to work after you take it? For pain and swelling it can have immediate effects post-surgery, but for more gradual or ongoing treatments, the effects might be felt over a period of weeks. It truly depends on your condition, your health, and how you're using the supplement.
Serrapeptase alternatives include essential amino acid supplements, proven effective for healing, muscle-building, and anti-inflammation, and safe and side-effect free.
The Secrets of Serrapeptase
Our understanding of serrapeptase is far from comprehensive at this moment. There is one study linking it to treatment of carpal tunnel syndrome and anecdotal evidence suggesting serrapeptase for weight loss (albeit temporary). There are far more clinical studies on the use of serrapeptase for reducing inflammation, fighting infections, and preventing blood clots, but researchers are still exploring its uses. Should you be interested in seeing what serrapeptase supplementation can do for you, we only ask that you do so wisely, and with a willingness to consult a medical professional about any results you find, be they bad or good.
