INSUFFICIENT RELIABLE EVIDENCE to RATE

• Age-related macular degeneration (AMD). It is unclear if oral goji berry reduces the risk of developing AMD. Details: A small, unblinded clinical study in healthy adults aged 45 to 65 years shows that consuming goji berries 28 grams five times a week for 90 days improves macular pigment optical density, which is a marker for AMD, when compared to baseline (110767). The validity of this finding is limited by the lack of statistical comparison to the other study group that received a supplement containing lutein and zeaxanthin.
• Cancer. Although there is interest in using oral goji for cancer, there is insufficient reliable information about the clinical effects of goji for this condition.
• Cardiovascular disease (CVD). It is unclear if oral goji improves risk factors for CVD. Details: A meta-analysis of 6 mostly small clinical studies of adults in China shows that consuming goji as polysaccharide extract or juice for 1-3 months modestly improves triglycerides, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and fasting blood glucose but does not impact total cholesterol when compared with no treatment or placebo (110765). Another meta-analysis of 4 small clinical studies in adults also shows that consuming goji polysaccharide extract or goji berries for 1-4 months modestly improves triglycerides and HDL but does not impact total or LDL cholesterol when compared with placebo or healthy eating. Goji also had no impact on systolic or diastolic blood pressure, or markers of oxidative stress (110768). However, the interpretation of the findings from these meta-analyses is limited by the use of variable goji forms and doses, as well as inclusion of studies in heterogeneous patients, including healthy people, patients with diabetes, and patients with metabolic syndrome. Furthermore, most studies were conducted in China; it is unclear if these benefits can be extrapolated to other geographic locations.
• Cognitive function. It is unclear if oral goji berry improves cognition in healthy young individuals. Details: A small clinical crossover study in healthy participants 14-24 years of age shows that taking goji berry fruit water extract (BIOMIX Company) 3600 mg in 3 divided doses daily for 4 weeks might improve certain cognitive measures such as verbal learning, short-term memory, and attention when compared with baseline (105488). The validity of these findings are limited due to incomplete outcome reporting and a lack of statistical comparisons between the treatment and placebo groups.
• Cough. Although there is interest in using oral goji for cough, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Depression. It is unclear if oral goji berry polysaccharide is beneficial for adolescents with subthreshold depression. Details: A small clinical study in adolescents aged approximately 15 years with subthreshold depression in China shows that taking goji berry polysaccharide extract 300 mg daily for 6 weeks modestly improves clinician-assessed depression scores (i.e. Hamilton Depression Scale, HAMD-24) but does not improve self-reported depression scores (i.e. Beck Depression Inventory) or scores assessing sleep quality, psychological distress, or anxiety when compared with placebo (110769). However, these results are from an interim analysis, which limits the interpretation of these findings. Furthermore, it is unclear if results can be extrapolated to patients in other geographic locations.
• Diabetes. It is unclear if oral goji berry polysaccharides improve glycemic control in patients with diabetes. Details: One small clinical study in patients with type 2 diabetes shows that taking goji fruit polysaccharide powder 150 mg twice daily for 3 months results in a slightly lower postprandial glucose area under the curve (AUC), but does not seem to affect insulin levels or insulin resistance, when compared with placebo. A subgroup of patients who were not taking antidiabetes medications had a greater reduction in postprandial blood glucose (92117).
• Dry eye. Although there is interest in using oral goji for dry eye, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Erectile dysfunction (ED). Although there is interest in using oral goji for ED, there is insufficient reliable information about the clinical effects of goji for this condition.
• Hypertension. Although there is interest in using oral goji root bark for hypertension, there is insufficient reliable information about the clinical effects of goji for this condition.
• Obesity. It is unclear if oral goji berry juice improves weight loss. Details: Preliminary clinical research in healthy, overweight adults shows that drinking a specific goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14 days while following a weight loss diet and participating in an exercise program decreases waist circumference by about 4.7 cm more than exercise and diet alone. However, drinking goji berry juice along with diet and exercise does not improve body weight, body mass index, or body fat when compared with diet and exercise alone (52536).
• Quality of life. Small clinical studies suggest that oral goji berry juice may modestly improve quality of life in healthy adults. Details: Small clinical studies in healthy adults suggest that taking a specific standardized goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14-30 days improves subjective measures of energy levels, athletic performance, sleep quality, mental acuity, calmness, feelings of well-being, and gastrointestinal regularity when compared with placebo (17082,52532,52542). These studies were funded by the juice manufacturer.
• Sunburn. It is unclear if oral goji extract can prevent sunburn. Details: A small clinical study in healthy Japanese adults shows that taking goji extract 900 mg daily for 8 weeks reduces and accelerates resolution of erythema after exposure to a standard dose of UVB irradiation when compared with placebo (110770). All study participants were highly UV-sensitive; it is unclear whether these results can be extrapolated to individuals less sensitive to UV irradiation.
• Tinnitus. Although there is interest in using oral goji for tinnitus, there is insufficient reliable information about the clinical effects of goji for this purpose. More evidence is needed to rate goji for these uses.

POSSIBLY EFFECTIVE

• 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).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• 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.
• Chronic obstructive pulmonary disease (COPD). Although there is interest in using oral MSM for COPD, there is insufficient reliable information about the clinical effects of MSM for this condition.

• Diabetes. Although there is interest in using oral MSM for diabetes, 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.

(110572). However, this study may have been underpowered to detect differences between groups.
• Osteoporosis. Although there is interest in using oral MSM for osteoporosis, there is insufficient reliable information about the clinical effects of MSM for this condition.
• Periodontitis. Although there is interest in using topical MSM for periodontitis, 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). The validity of these findings is limited by the lack of a comparator group.

POSSIBLY SAFE ...when goji fruit preparations are used orally and appropriately, short-term. Goji berry whole fruit, boiled or steamed, has been used with apparent safety at a dose of 15 grams daily for 16 weeks (105489). Other goji berry products have also been used with apparent safety in clinical research, including a specific goji fruit juice (GoChi, FreeLife International) 120 mL daily for 30 days (52532), a goji fruit polysaccharide 300 mg daily for 3 months (92117), and a specific milk-based formulation of goji berry (Lacto-Wolfberry, Nestlé Research Center) for 3 months (52539). There has been some concern about the atropine content of goji; however, most analyses show that levels of atropine in goji berries from China and Thailand are far below potentially toxic levels (52524,94667). There is insufficient reliable information available about the safety of oral use of other parts of the goji plant.

PREGNANCY AND LACTATION:
Insufficient reliable information available. Some animal research shows that goji fruit may stimulate the uterus (12). However, this has not been reported in humans. Until more is known, avoid using during pregnancy or lactation.

ANTIDIABETES DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.  Details Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects (7126,92118,94667). However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia (92117).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.  Details Animal and in vitro research suggest that goji root bark has hypotensive effects (7126,94667). However, goji fruit juice does not appear to reduce systolic or diastolic blood pressure in humans (17082).

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.  Details In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.  Details In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes (105486). Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate (7158,105462). Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.  Details In vitro research shows that goji berry juice inhibits CYP2D6 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.  Details In vitro research shows that goji berry juice inhibits CYP3A4 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.

FLECAINIDE (Tambocor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might increase the levels and clinical effects of flecainide.  Details In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide (105462).

WARFARIN (Coumadin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Goji can increase the effects of warfarin and possibly increase the risk of bleeding.  Details There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine (7158,16529,23896,105462,105487). Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9) (7158).

General ...Orally, goji fruit seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions including anaphylaxis.

Dermatologic ...A case of photosensitivity secondary to consumption of goji berries has been reported. The patient presented with a pruriginous eruption that had lasted for 2 weeks. The patient had been taking goji berries for 5 months and cat's claw for 3 months. Upon testing, it was revealed that the patient tested positive to goji berries in a photoprovocation test, but not to cat's claw (40263).

Hepatic ...Orally, consumption of goji berries has been associated with a single case report of autoimmune hepatitis (52541). A case of acute hepatitis has also been reported in a female who consumed 2 ounces of a specific combination product (Euforia, Nuverus International) containing goji berry, pomegranate, curcumin, green tea, noni, acai berry, aloe vera, blueberry, resveratrol, mangosteen, and black seed, daily for one month. It is unclear whether the liver injury was caused by goji berry, other ingredients, or the combination (90125).
