• Burns. There is some evidence that taking a trypsin / chymotrypsin mixture orally might decrease tissue destruction in burn patients (716).
• Chronic obstructive parotitis. Preliminary clinical research shows that injecting a combination of chymotrypsin 5 mg and gentamicin into the parotid salivary gland ducts and then draining after 3-5 minutes improves subjective measures of pain and swelling in chronic obstructive parotitis when compared with gentamicin alone (99720).
• Fractures. Preliminary clinical research shows that taking a combination of trypsin and chymotrypsin orally seems to reduce inflammation and edema associated with hand fractures (717,718). More evidence is needed to rate chymotrypsin for these uses.

• Celiac disease. Although there has been interest in using oral lipase for celiac disease, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Dyspepsia. It is unclear if oral lipase is beneficial for improving symptoms of postprandial distress syndrome. Details: A small clinical trial shows that taking a specific acid-resistant lipase (Amano Enzyme USA) 280 mg immediately before a high-fat meal does not reduce postprandial bloating and nausea when compared with placebo in individuals with postprandial distress syndrome (101900).
• Inflammatory bowel disease (IBD). Although there has been interest in using oral lipase for IBD, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Prematurity. It is unclear if adding a specific form of lipase, recombinant human bile salt-stimulated lipase (rhBSSL), to infant formula improves outcomes in premature infants. Some research suggests a potential increased risk for adverse effects. Details: Human breast milk contains rhBSSL, but it is inactivated when breast milk is pasteurized for donation. Clinical research in infants born before 32 weeks' gestation shows that adding rhBSSL as 8700 units per 100 mL formula or pasteurized breast milk, for 4 weeks does not increase growth velocity, body length, or head circumference over the next 12 months when compared with formula or pasteurized breast milk devoid of lipase. However, the infants who were small for gestational age (SGA), which made up approximately 15% of the study population, grew by an additional 1.9 grams/kg daily on average when compared with placebo (101940). More evidence is needed to rate lipase for these uses.

• Aging skin. In patients with deep wrinkles, preliminary clinical research shows that taking zinc citrate 50 mg and phytase 3,000 units daily for four days prior to a botulinum toxin treatment increases the patient-reported duration of botulinum toxin effects by approximately 25%, compared with no improvement in patients taking zinc gluconate 10 mg or placebo. The efficacy of botulinum treatment was also improved (101913). Whether this reported benefit is due to the dose or form of zinc, citrate, phytase, the combination, or other factors, is unclear (101913,101914).
• Blepharospasm. In patients with blepharospasm, preliminary clinical research shows that taking zinc citrate 50 mg and phytase 3,000 units daily for four days prior to a botulinum toxin treatment increases the patient-reported duration of botulinum toxin effects by approximately 25%, compared with no improvement in patients taking zinc gluconate 10 mg or placebo. The efficacy of botulinum treatment was also improved (101913). Whether this reported benefit is due to the dose or form of zinc, citrate, phytase, the combination, or other factors, is unclear (101913,101914).
• Child growth. Clinical research in infants consuming a corn-based diet shows that taking a fat- and micronutrient-based food supplement containing phytase, docosahexaenoic acid (DHA), arachidonic acid, and lysine increases linear growth at age 8 and 10 months and improves locomotor development when compared with not taking this supplement. In contrast, a similar fat- and micronutrient-based supplement without phytase, DHA, arachidonic acid, and lysine does not improve these indices when compared with not taking a supplement. The phytase-containing supplement did not affect linear growth, weight for age, or hand-eye coordination at 12 months (101902). These reported benefits to child growth are likely to be due to the combination of provided essential and non-essential nutrients. Any role of phytase is expected to be minimal.
• Iron deficiency anemia. Taking phytase with a meal containing phytate and iron increases iron absorption (101903,101904,101906). However, the effect of phytase specifically for the treatment of iron deficiency anemia remains unclear (101902). Phytase is sometimes added to the diet to increase the absorption of iron from food. In a small study of women, some with iron deficiency anemia, incubating wheat as a source of phytase with a traditional grain high in phytate increased iron absorption from the meal to 8.3% from 2.6% (101904). Also, adding microbial phytase to whole wheat rolls containing phytate increases iron absorption from a meal by approximately 82% when compared with rolls without added phytase (101906). In another small study, the addition of a microbial phytase to a single corn meal with added micronutrients increases iron absorption and incorporation into red blood cells after 14 days by 1.85-fold when compared with the meal without added phytase (101903). However, consuming white wheat rolls with added wheat bran as a source of phytase does not increase iron absorption from the meal when compared to consuming rolls with added wheat bran with deactivated phytase (101906). The use of phytase as treatment for iron deficiency, with or without anemia, has rarely been investigated. However, clinical research in infants consuming a corn-based diet shows that taking a fat- and micronutrient-based food supplement containing phytase, docosahexaenoic acid (DHA), arachidonic acid, and lysine for 6 months does not seem to be more effective for reducing anemia than taking the food supplement without phytase (101902).
• Zinc deficiency. Preliminary clinical research shows that adding phytase 20.5 units to a millet-based porridge with added zinc immediately prior to consumption increases zinc absorption by approximately 68% in children aged 12-24 months (101911). Some of these children had low plasma levels of zinc at baseline. However, the use of phytase specifically for the treatment of zinc deficiency has not been investigated. More evidence is needed to rate phytase for these uses.

• Colorectal cancer. A small clinical study in patients with colorectal cancer receiving chemotherapy shows that taking a specific combination supplement containing trypsin and other enzymes (Wobe-Mugos E) attenuates worsening quality of life, modestly increases relapse-free survival, and increases the number of patients surviving over 42 months (99474). The effects of trypsin alone are unclear.
• Diabetes. A small observational study in patients with a family history of type 1 diabetes found that taking a product containing trypsin 48 mg, bromelain 90 mg, and rutin 100 mg (Mucos Pharma) daily for 24 months is not associated with reduced incidence of type 1 diabetes at 8 years (99472). Further higher quality research is needed to draw a conclusion.
• Exercise-induced muscle soreness. A small clinical study shows that taking a combination protease tablet containing papain 50 mg, trypsin 75 mg, bromelain 50 mg, amylase 10 mg, lipase 10 mg, lysosome 10 mg, and chymotrypsin 2 mg, four times in one day before downhill running can improve recovery of contractile muscle function and decrease muscle soreness compared to placebo (67838). The effects of trypsin alone are unclear.
• Exercise-induced respiratory infections. A small clinical study in non-elite male runners shows that taking a combination product (Wobenzym Plus, Mucos Pharma) providing rutin 600-1200 mg, trypsin 288-576 mg, and bromelain 540-1080 mg daily for 3 weeks starting one week before a marathon, does not reduce the risk of a post-race upper respiratory tract infection when compared with placebo (96766). A limitation of this study is that it was not powered to detect a difference in exercise-induced infections between groups.
• Multiple sclerosis (MS). A preliminary clinical study in patients with relapsing-remitting MS shows that taking an enzyme combination containing trypsin 48 mg, bromelain 90 mg, and rutin 100 mg per tablet for at least 3 months does not affect disability progression, relapses or central nervous system lesions when compared with placebo (99468). The validity of these results are limited by the short duration of treatment, and the effects of trypsin alone are unclear.
• Osteoarthritis. Taking trypsin orally in combination with rutin and bromelain seems to be effective for treating osteoarthritis of the knee. Most clinical research in patients with knee osteoarthritis shows that taking the combination enzyme product (Wobenzym PS, formerly Phlogenzym, Mucos Pharma) at a dose providing up to 600 mg rutin, 288 mg trypsin, and 540 mg bromelain daily for 3-12 weeks, is as effective as diclofenac (Voltaren) 50 mg two to three times daily for relieving pain and improving knee function. This product also seems to reduce the need for rescue medication by 95% compared to placebo (6252,92235,99467,99477). It is unclear if these improvements are due to trypsin, other ingredients, or the combination. Trypsin has not been studied for osteoarthritis as a single-ingredient product.
• Postoperative swelling. A small preliminary clinical study in patients undergoing surgery of the jaw shows that taking an enzyme combination of trypsin 96 mg, bromelain 180 mg, and rutin 200 mg twice daily for 5 days in addition to standard treatment reduces soft-tissue thickness (indicating the amount of swelling) at most of the nine assessed facial-points compared to control (99476). This study is limited by its small size and significant differences in swelling at pre-determined points during the first postoperative day. This suggests that factors in addition to enzyme therapy might have influenced the differences in results.
• Radiation dermatitis. There is conflicting evidence whether taking a combination supplement containing trypsin reduces adverse effects from radiation. Some low quality clinical research in cancer patients receiving radiation therapy suggests that a specific combination product (Wobe-Mugos E, Mucos Pharma), which contains trypsin 40 mg, and other enzymes might reduce adverse reactions at the site of radiation, such as skin deterioration, when compared to no additional treatment (67831,99471). The results are these studies are limited by a lack of blinding and a lack placebo control. Evidence from another small, but higher quality clinical study shows that taking the same product beginning 3 days prior to radiation and continuing until the last day of radiation therapy does not reduce acute radiation-related complications such as skin deterioration when compared to placebo (67834).
• Sprains. A preliminary clinical study in patients with a sprained ankle shows that taking a specific enzyme combination (Phlogenzym, Mucos Pharma) containing trypsin 48 mg, bromelain 90 mg, rutin 100 mg, or taking different combinations of the individual enzymes three times daily for 10 days is not more effective for relieving pain than placebo (99473). The effects of trypsin alone are unclear.
• Wound healing. Some preliminary evidence suggests that applying trypsin topically in combination with chymotrypsin may be helpful for cleansing wounds of necrotic material and enhancing wound healing (715,716). Other preliminary research suggests that applying trypsin topically in combination with castor oil and Peru balsam may improve wound healing, including the healing of infected wounds. However, as a debriding agent, trypsin seems to be no better than mechanical gauze (99573). In fact, the US Food and Drug Administration (FDA) determined in the 1970s that trypsin is ineffective as a debriding agent (95757). There is insufficient reliable information available about the effectiveness of trypsin for these uses.

POSSIBLY SAFE ...when used topically by healthcare professionals trained in wound debridement (506). There is insufficient reliable information available about the safety of trypsin for its other uses. Although trypsin has been safely used in clinical research in doses of up to 288 mg orally daily in combination with other enzymes for up to 3 months, it is unclear if trypsin taken orally alone is safe (37193,92235,99473).

General ...There is currently a limited amount of information available about the adverse effects of chymotrypsin. Orally, hypersensitivity reactions, including anaphylaxis, have been reported (9). When injected into the eye, chymotrypsin has been reported to cause increased intraocular pressure and uveitis (9,509).

Immunologic ...Rarely, chymotrypsin has been reported to cause anaphylactic reactions characterized by dyspnea, urticaria, edema, shock, vascular collapse, and unconsciousness, which can lead to death (9,509).

Ocular/Otic ...Intraocular injections of chymotrypsin have been reported to cause increased intraocular pressure, corneal edema, striation, uveitis, iridoplegia, and filamentary keratitis (9,509).

General ...No adverse effects have been reported in adults. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.

Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).

General ...Orally, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted. Workplace immunological responses to airborne powdered phytase have been reported (101901,101908,101909,101910).

Immunologic ...There are numerous reports of immunologic responses to airborne powdered phytase in the animal-feed industry (101901,101908,101909,101910). Examples of reactions include allergic occupational asthma and hypersensitivity pneumonitis (101901,101908). In one case report of a 43-year-old male, hypersensitivity pneumonitis related to phytase was diagnosed following a 6-month history of coughing, shortness of breath, fever, and dyspnea (101908). In an analysis of 53 people occupationally exposed to phytase, 28% had IgE antibodies and 45% had IgG antibodies specific to phytase. Symptoms included dyspnea, rhinitis, and eye and skin reactions (101909). In another analysis of patients with IgE-mediated occupational respiratory allergy, wheezing, chest tightness, shortness of breath, cough, and asthmatic symptoms were reported (101910).
