• Osteoarthritis. Cetylated fatty acids seem to reduce pain and improve function when used orally or topically in patients with knee osteoarthritis. Details: Some clinical research in patients with knee osteoarthritis shows that taking a specific blend of cetylated fatty acids (Celadrin, Imagenetix Inc.) 350 mg combined with 50 mg soy lecithin and 75 mg fish oil twice daily for 68 days decreases pain and improves knee range of motion and function. However, it does not appear to improve morning stiffness (8924). Applying the same specific blend of cetylated fatty acids topically twice daily for 30 days, either alone or in combination with menthol for 7 days, also seems to decrease pain and improve functionality in patients with knee osteoarthritis (12076,13104,13105). Other preliminary clinical research in patients with knee osteoarthritis also shows that applying a cream containing a specific blend of cetylated fatty acids (Cetilar, PharmaNutra) to the knee twice daily for one week modestly reduces pain and improves functionality when compared with baseline. Stiffness was also improved in patients with moderate, but not mild, osteoarthritis based on radiographic measurements (101995).

• Fibromyalgia. Although there has been interest in using oral cetylated fatty acids for fibromyalgia, there is insufficient reliable information about the clinical effects of cetylated fatty acids for this purpose.
• Knee pain. It is unclear if oral cetylated fatty acids are beneficial for mild knee pain. Details: A small, preliminary study in adults with idiopathic mild knee pain shows that taking a specific cetylated fatty acid product (JOINTRUS, SFC Bio, Inc) 125 mg twice daily for 12 weeks does not improve pain scores when compared with placebo (97425).
• Juvenile idiopathic arthritis (JIA). Oral cetylated fatty acids have only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in children 2-16 years of age with JIA shows that taking a specific supplement (Kre-Celazine, All American Pharmaceutical) containing creatine and cetylated fatty acids 750 mg twice daily for 30 days may improve pain and inflammation when compared with baseline. Over 80% of patients reported near zero pain after use (90322). The validity of this study is limited by the lack of a comparator group. Additionally, it is unclear if any benefits were due to cetylated fatty acids, creatine, or the combination.
• Myofascial pain syndrome. Topical cetylated fatty acids have only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in patients with myofascial pain syndrome of the neck shows that applying a cream containing cetylated fatty acids 5.6% with menthol 1.5% twice daily, in addition to undergoing physical therapy twice weekly for 4 weeks, reduces pain by a small amount and improves disability by a moderate amount when compared to physical therapy alone (101997). It is unclear if the benefits of the cream were due to cetylated fatty acids, menthol, or the combination.
• Pain (chronic). It is unclear if topical cetylated fatty acids are beneficial in athletes with chronic groin and lower abdominal pain. Details: A very small, uncontrolled clinical study in professional roller hockey players who are participating in physical therapy shows that applying a specific cream or patch containing cetylated fatty acids (Cetilar Crema or Cetilar Patch, PharmaNutra) to the pelvic area on both limbs daily for 12 weeks, excluding weekends, improves symptoms of athletic pubalgia, a condition characterized by chronic groin and lower abdominal pain, when compared to baseline (107915). The validity of these findings is limited by a lack of control group. It is unclear if these findings are due to cetylated fatty acids, physical therapy, or the combination.

• 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.

• Osteoarthritis. Most clinical research shows that MSM is modestly beneficial when used alone or in combination with other ingredients. Details: Clinical research shows that taking MSM 1.5-6 grams orally in two to three divided doses daily, either alone or in combination with glucosamine, can modestly improve joint function and some symptoms of osteoarthritis such as pain and swelling (12469,14335,17127,19312). However, MSM does not seem to reduce stiffness or total symptom score (14335). Also, some patients may not consider the modest benefit to be clinically significant (17127). Some clinical research has evaluated MSM in combination with other ingredients. One clinical study in adults with knee osteoarthritis shows that taking MSM 500 mg, glucosamine sulfate 1500 mg, and chondroitin sulfate 1200 mg daily for 12 weeks is associated with greater reductions in pain and osteoarthritis scores when compared with glucosamine sulfate and chondroitin sulfate alone (96447). Clinical studies using combination products containing MSM 5 grams daily and boswellic acid 7.2 mg daily with or without vitamin C (Lignisul, Triterpenol; Artosulfur C, Laborest Italia S.p.A), orally for 60 days show reductions in anti-inflammatory drug use, but conflicting results for pain reduction (19313,96446). Also, one small study suggests that taking a combination of MSM with collagen type II, cetyl myristoleate, lipase, vitamin C, turmeric, and bromelain (AR7 Joint Complex, Robinson Pharma) orally for 12 weeks improves scores for joint pain and tenderness, but does not improve X-rays of affected joints (19314).

POSSIBLY INEFFECTIVE

• Chronic venous insufficiency (CVI). Clinical research suggests that topical MSM is not beneficial in CVI. Details: Clinical research shows that topical application of MSM plus EDTA can reduce the circumference of the calf, ankle, and foot in patients with CVI. However, application of MSM alone appears to increase swelling in these patients (19315).

• Aging skin. It is unclear if oral MSM improves the appearance of aging skin to a clinically meaningful extent. Details: Preliminary clinical research shows that taking MSM (OptiMSM, Bergstrom Nutrition) 3 grams daily for 16 weeks improves facial wrinkles associated with aging by a moderate amount when compared with placebo. When compared with baseline, taking MSM 1 gram daily for 16 weeks is as effective as taking 3 grams for reducing fine lines and wrinkles and improving smoothness, radiance, firmness, and elasticity (102000).
• Allergic rhinitis (hay fever). It is unclear if oral MSM is beneficial in patients with allergic rhinitis. Details: Preliminary clinical research shows that taking MSM (OptiMSM 650 mg) 2600 mg orally for 30 days might relieve some symptoms of seasonal allergic rhinitis when compared with baseline (8574). However, this study lacked blinding and a control group, and also did not provide information on severity of symptoms (12000).
• Alzheimer disease. Although there is interest in using oral MSM for Alzheimer disease, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Androgenic alopecia. Although there is interest in using oral and topical MSM for androgenic alopecia, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Aromatase inhibitor-induced arthralgia. Oral MSM has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with estrogen receptor positive (ER+) breast cancer and aromatase inhibitor-induced arthralgia shows that taking a specific combination product (Opera, GAMFARMA s.r.l) containing MSM 200 mg, boswellia 40 mg, alpha-lipoic acid 240 mg, and bromelain 20 mg once daily for 6 months reduces arthralgia intensity when compared to baseline, with around 22% of patients having complete symptom resolution at the end of the study (109570). The validity of these findings is limited by a lack of control group.
• Asthma. Although there is interest in using oral MSM for asthma, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Athletic performance. It is unclear if topical MSM is beneficial for improving athletic performance. Details: A small clinical study in healthy, physically active adults shows that applying a specific cream containing magnesium and MSM (MagPro, Custom Prescription Shoppe) prior to stretching and pedaling on a stationary bicycle does not appear to improve flexibility or endurance when compared with a placebo cream (19317).
• Chemotherapy-induced peripheral neuropathy. Oral MSM has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with chemotherapy-induced peripheral neuropathy shows that taking a specific product (OPERA, GAMFARMA s.r.l.) containing MSM 200 mg, alpha-lipoic acid 240 mg, boswellia 40 mg, and bromelain 20 mg daily for 12 weeks reduces overall pain when compared with baseline (96449). The validity of these findings is limited by the lack of a placebo group. Additionally, it is not clear if benefit is associated with MSM, other ingredients, or the combination.
• Chronic fatigue syndrome (CFS). Although there is interest in using oral MSM for CFS, there is insufficient reliable information about the clinical effects of MSM for this condition.

• Dyslipidemia. It is unclear if oral MSM is beneficial for dyslipidemia. Details: A very small clinical study in adults with overweight or obesity shows that taking a specific MSM product (OptiMSM, Bergstrom Nutrition) 3 grams daily for 16 weeks modestly increases high-density lipoprotein (HDL) cholesterol when compared with baseline, but not when compared with placebo. Taking MSM also did not improve total cholesterol, low-density lipoprotein (LDL) cholesterol, very-low-density lipoprotein (VLDL) cholesterol, or triglycerides (110572). However, this study may have been underpowered to detect differences between groups.
• Dyspepsia. Although there is interest in using oral MSM for dyspepsia, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Exercise-induced muscle damage. It is unclear if oral MSM is beneficial for preventing exercise-induced muscle damage. Details: Clinical research shows that taking MSM 50 mg/kg in 200 mL water orally daily beginning 10 days prior to a 14-km run can attenuate the increase in creatine kinase (CK) and bilirubin levels caused by exercise-induced muscle damage (19320). However, other clinical research shows that taking MSM (OptiMSM, Bergstrom Nutrition) 3 grams daily beginning 3 weeks prior to a 13.1-mile run and continuing for 2 days after does not reduce muscle or joint pain or alter serum markers of oxidative stress or muscle damage when compared with placebo (96448).
• Hangover. Although there is interest in using oral MSM for hangover, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Hemorrhoids. Topical MSM has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study shows that applying a specific gel containing MSM in combination with hyaluronic acid and tea tree oil (Proctoial, BSD Pharma) for 14 days improves symptoms of hemorrhoids, including pain during defecation, visible bleeding, and inflammation/irritation, when compared with placebo (19318). It is not clear if these effects are due to MSM, the other ingredients, or the combination.
• Insect bite. Although there is interest in using oral MSM for preventing insect bites, there is insufficient reliable information about the clinical effects of MSM for this condition.

• Pneumonia. Although there is interest in using oral MSM for pneumonia, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Postoperative pain. Oral MSM has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients who have undergone arthroscopic rotator cuff repair shows that taking a specific combination product (Tenosan, Agave s.r.l.) containing MSM 550 mg, arginine alpha-ketoglutarate 500 mg, collagen peptides 300 mg, apple and grape polyphenols 125 mg, bromelain 40 mg, and vitamin C 60 mg for 3 months can reduce postoperative pain and slightly improve repair integrity (19322). However, improvement in overall functional outcomes was not observed.
• Rheumatoid arthritis (RA). Although there is interest in using oral and topical MSM for RA, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Rosacea. Oral MSM has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with rosacea shows that topical application of a cream containing silymarin and MSM twice daily for one month improves skin redness, papules, itching, hydration, and skin color when compared to baseline (19319).

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).
