N-acetyl glucosamine 3-4 grams daily in 2 divided doses has been safely used (10234). ...when glucosamine sulfate is used intramuscularly and appropriately, short-term. Intramuscular glucosamine sulfate seems to be well tolerated when given twice weekly for up to 6 weeks (2605).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. Oral manganese is safe when used in doses below the tolerable upper intake level (UL) of 11 mg daily for adults 19 years and older (1994,7135). ...when used parenterally and appropriately. Parenteral manganese chloride and manganese sulfate are FDA-approved prescription products.
POSSIBLY UNSAFE ...when used orally in high doses. Doses exceeding 11 mg daily can cause significant adverse effects (7135). ...when used parenterally in moderate or high doses, long-term. Reports of neurotoxicity and Parkinson-like symptoms have been reported with parenteral nutrition manganese doses above 60 mcg daily. It is recommended that adults on long-term parenteral nutrition receive manganese in doses of no more than 55 mcg daily (99302).
LIKELY UNSAFE ...when inhaled in moderate doses, long-term. According to the US Occupational Safety and Health Administration (OSHA), the permissible exposure limit (PEL) for manganese is 5 mg/m3. Exposure to higher amounts of manganese dust or fumes has been associated with central nervous system toxicity, Parkinson-like symptoms, and poor bone health (61296,102516).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Manganese is safe in children when used in daily doses less than the tolerable upper intake level (UL) of 2 mg in children 1-3 years, 3 mg in children 4-8 years, 6 mg in children 9-13 years, and 9 mg in children 14-18 years (7135).
CHILDREN: POSSIBLY UNSAFE
when used orally in excessive doses.
Daily doses greater than the UL are associated with a greater risk of toxicity (7135).
CHILDREN: LIKELY UNSAFE
when inhaled at moderate doses, long-term.
Exposure to high amounts of manganese dust has been associated with central nervous system toxicity and Parkinson-like symptoms (61296).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Manganese is safe when used in doses below the tolerable upper intake level (UL) of 11 mg daily during pregnancy or lactation in those aged 19 or older. However, those under 19 years of age should limit doses to less than 9 mg daily (7135).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
Doses over the UL are associated with a greater risk of toxicity (7135). Additionally, observational research shows that adults with higher blood manganese levels have greater odds of delivering low birth weight or small for gestational age (SGA) male, but not female, infants (102515).
PREGNANCY AND LACTATION: LIKELY UNSAFE
when inhaled at moderate doses, long-term.
Manganese salts can cross the placenta, and animal research suggests that large amounts of manganese may be teratogenic (61296).
POSSIBLY SAFE ...when used orally and appropriately, short term. MSM in doses of 1.5-6 grams daily or 50 mg/kg daily has been used safely in studies lasting up to 6 months (8574,12469,14335,17127,19312,96446,96448,102555). One specific product (OptiMSM, Bergstrom Nutrition) is Generally Recognized As Safe (GRAS) by the United States Food and Drug Administration (FDA) (102555). ...when used topically. Topical cream containing MSM and silymarin, as well as topical gel containing MSM, hyaluronic acid, and tea tree oil, have been used with apparent safety for up to 20 days (19318,19319).

Below is general information about the interactions of the known ingredients contained in the product Sea Mussel Plus. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Acetaminophen might interfere with the activity of glucosamine sulfate by interacting with the sulfate portion.
 Details
Anecdotal reports suggest that adding glucosamine to an acetaminophen regimen might decrease pain control in patients with osteoarthritis (14806). Some research suggests that the sulfate portion of glucosamine sulfate might contribute to its effect in osteoarthritis. Since acetaminophen metabolism requires sulfur and reduces serum sulfate concentrations, acetaminophen could theoretically interfere with the action of glucosamine sulfate. Conversely, the administration of sulfate could theoretically decrease the effectiveness of acetaminophen in sulfate-deficient people by increasing its clearance (10313).
|
Despite initial concerns, it is unlikely that glucosamine will interfere with the effects of antidiabetes drugs.
Details
In vitro and animal research has suggested that glucosamine might increase insulin resistance or decrease insulin production (371,372,3406,18342,18343). This has raised concerns that taking glucosamine might worsen diabetes and decrease the effectiveness of diabetes drugs. However, clinical research suggests that glucosamine does not have adverse effects on blood glucose or glycated hemoglobin (HbA1C) in healthy, obese, or type 2 diabetes patients (7026,7075,8942,10311,10317,15111).
|
Theoretically glucosamine may induce resistance to topoisomerase II inhibitors.
Details
In vitro research suggests that glucosamine might induce resistance to etoposide (VP16, VePesid) and doxorubicin (Adriamycin) by reducing inhibition of topoisomerase II, an enzyme required for DNA replication in tumor cells (7639). This effect has not been reported in humans.
|
Glucosamine might increase the anticoagulant effects of warfarin and increase the risk of bruising and bleeding.
Details
In two individual case reports, glucosamine/chondroitin combinations were associated with a significant increase in international normalized ratio (INR) in patients previously stabilized on warfarin (11389,16130). In one case, the increase in INR occurred only after tripling the dose of a glucosamine/chondroitin supplement from 500 mg/400 mg daily to 1500/1200 mg daily (16130). Additionally, 20 voluntary case reports to the U.S. Food & Drug Administration (FDA) have linked glucosamine plus chondroitin with increased INR, bruising, and bleeding in patients who were also taking warfarin (16130). There have also been 20 additional case reports to the World Health Organization (WHO) that link glucosamine alone to increased INR in patients taking warfarin (16131). The mechanism of this interaction is unclear. Glucosamine is a small component of heparin, but is not thought to have anticoagulant activity; however, animal research suggests that it might have antiplatelet activity (16131).
|
Theoretically, the risk for manganese toxicity might increase when taken with antipsychotic drugs.
Details
Hallucinations and behavioral changes have been reported in a patient with liver disease who was taking haloperidol and manganese. Researchers speculate that taking manganese along with haloperidol, phenothiazine-derivatives, or other antipsychotic medications might increase the risk of manganese toxicity in some patients (61493).
|
Theoretically, manganese might reduce the absorption of quinolone antibiotics.
Details
Manganese is a multivalent cation. Interactions resulting in reduced quinolone absorption have been reported between quinolones and other multivalent cations, such as calcium and iron (488).
|
Theoretically, manganese might reduce the absorption of tetracycline antibiotics.
Details
Manganese is a multivalent cation. Interactions resulting in reduced tetracycline absorption have been reported between tetracyclines and other multivalent cations, such as calcium and iron (488).

Below is general information about the adverse effects of the known ingredients contained in the product Sea Mussel Plus. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General ...Orally, no adverse effects have been reported in clinical trials in adults and children using dimethylglycine. However, a thorough evaluation of safety outcomes has not been conducted.
Gastrointestinal ...Theoretically, dimethylglycine might react with nitrites in the gastrointestinal tract to form carcinogenic substances (5827). However, research suggests that dimethylglycine does not react with nitrites and is not carcinogenic (13172).
General
...Orally, all forms of glucosamine seem to be well tolerated.
Topically and rectally, N-acetyl glucosamine also seems to be well tolerated. Intramuscularly, glucosamine sulfate seems to be well tolerated. However, a thorough evaluation of safety outcomes has not been conducted for non-oral routes of administration.
Most Common Adverse Effects:
Orally: Bloating, constipation, cramps, diarrhea, heartburn, nausea.
Serious Adverse Effects (Rare):
Orally: There have been rare reports of severe allergic reactions and hepatotoxicity.
Cardiovascular
...One case of mesenteric occlusion in a clinical trial was considered possibly related to use of oral glucosamine hydrochloride and chondroitin sulfate (89520).
Some observational research has found that glucosamine use in patients with osteoarthritis is associated with a higher risk of cardiovascular disease (CVD) events when compared with non-use (109642). However, glucosamine users tended to be older, have multiple comorbidities, and be on antihyperlipidemic or antiplatelet therapy. Furthermore, other observational research in healthy adults has found that glucosamine use is associated with a reduced risk of fatal and non-fatal CVD events (99682). Higher quality, prospective research is needed to clarify the relationship, if any, between glucosamine and CVD risk.
Dermatologic ...Orally, glucosamine might cause skin reactions, including itching, rash, and erythema (2608,20084,89567,110628). Also, fingernail and toenail toughening, with an increased rate of growth, has been reported (89572). Topically, N-acetyl glucosamine 2% with niacinamide 4% cream might cause rare skin reactions (92721). Photosensitization that was reproducible with re-challenge was reported in a case report of an individual using glucosamine (form unknown) and chondroitin (10408).
Endocrine ...Orally, glucosamine does not seem to impact blood glucose. Preliminary research and anecdotal reports have found that various forms of glucosamine might increase insulin resistance or decrease insulin production, increasing fasting plasma glucose levels (22,371,372,1203,3406,5059,7637,14810). This has raised concerns that taking glucosamine sulfate might worsen diabetes and decrease the effectiveness of diabetes drugs. However, clinical research suggests that various forms of glucosamine do not have adverse effects on blood glucose or glycated hemoglobin (HbA1C) in healthy, obese, patients with type 2 diabetes or impaired glucose tolerance (7026,7075,7638,8942,10311,10317,12107,14808,15111,89563).
Gastrointestinal ...Orally, glucosamine has been associated with gastrointestinal problems, including epigastric and abdominal pain, cramps, heartburn, diarrhea, nausea, dyspepsia, vomiting, constipation, and flatulence (1520,2608,16717,20084,20104,20105,89561,89562,89567,89568)(108897,110628,111647). In older persons, use of glucosamine sulfate is associated with oral dryness (89564). In a clinical trial, a case of Helicobacter pylori gastritis was considered probably related to the use of glucosamine hydrochloride (89516).
Hepatic ...Although relatively uncommon, combinations of glucosamine and chondroitin sulfate have been associated with acute liver injury that mimics autoimmune hepatitis. Of 151 patients at an outpatient clinic for liver diseases, 23 acknowledged use of products containing glucosamine (form unspecified) and/or chondroitin. However, only 2 cases had an apparent relationship between transaminase elevation and the use of recommended doses of glucosamine and chondroitin sulfate. Aminotransferase levels, which were increased by four- to seven-fold, returned to normal following discontinuation of treatment (89515). In another case, a 65-year-old male presented to the hospital with signs and symptoms of drug-induced autoimmune hepatitis. The patient had used Condrosulf, containing chondroitin sulfate, for two years, followed by Vita Mobility Complex, containing chondroitin sulfate and glucosamine sulfate, for 8 weeks. The patient required maintenance treatment with azathioprine to remain in remission (89518). A case of acute cholestatic hepatitis due to Glucosamine Forte, which contains glucosamine hydrochloride, chondroitin sulfate, Devil's claw, and shark cartilage, has been reported (89522). It is unclear whether these adverse events were related to glucosamine, other ingredients, or the combination.
Immunologic ...There is some concern that glucosamine products might cause allergic reactions in sensitive individuals. One review of glucosamine-related adverse events in Australia found that 72% of all reports involved hypersensitivity reactions. Of these reactions, 35% were mild, including pruritis, urticaria, and lip edema, 49% were moderate, including dyspnea, and 16% were severe, including gait disturbance, somnolence, and hypotension. Anaphylaxis was reported in 1.5% of cases (102115). Also, in one clinical trial, a single patient developed allergic dermatitis considered to be likely due to glucosamine hydrochloride (89516). Glucosamine is derived from the exoskeletons of shrimp, lobster, and crabs. However, it is unclear if these adverse reactions were due to a shellfish sensitivity or general atopy. Additionally, shellfish allergies are caused by IgE antibodies to antigens in the meat of shellfish, not to antigens in the exoskeleton. Regardless, it is possible that some glucosamine products might be contaminated by this allergen during production (102115).
Neurologic/CNS ...Orally, glucosamine has been reported to cause drowsiness and headache (2608,89561). Glucosamine plus chondroitin combination products that also contain manganese (e.g., CosaminDS) should always be taken according to product directions. When taken at doses slightly higher than the recommended dose, these products can sometimes supply greater than the tolerable upper limit (UL) for manganese which is 11 mg/day. Ingestion of more than 11 mg/day of manganese might cause significant central nervous system toxicity (7135).
Ocular/Otic ...In older persons, use of glucosamine sulfate has been associated with ocular dryness (89564). Increased intraocular pressure has occurred with glucosamine sulfate supplementation (89573,112460). Data from the FDA MedWatch adverse event reporting system shows that 0.21% of subjects taking glucosamine reported glaucoma, which is significantly greater than the 0.08% of subjects who reported glaucoma while using any other drug (112460).
Pulmonary/Respiratory ...Cases of asthma exacerbations associated with the use of glucosamine (form unknown)-chondroitin products have been reported (10002).
Renal ...Anecdotal reports have associated glucosamine with nephrotoxicity signals such as modestly elevated creatine phosphokinase and 1+ to 2+ proteinuria, but changes in kidney function have not been reported in long-term studies (7026,8942,10408,10409). It was also noted that effects may have been due to other concurrent medications or impurities in glucosamine-chondroitin products. Cases of acute interstitial nephritis induced by glucosamine (form unknown) have also been reported (89523).
Other ...There has been concern that glucosamine might increase the risk of metabolic disturbances resulting in increased cholesterol levels and blood pressure. However, glucosamine does not appear to increase the risk of these adverse effects. Taking glucosamine sulfate for up to 3 years does not significantly increase blood glucose or lipid levels, or cause any other disturbances in metabolism (7026,7075,8942,10311,10317).
General
...Orally and parenterally, manganese is generally well tolerated when used in appropriate doses.
High doses might be unsafe.
Serious Adverse Effects (Rare):
All routes of administration: Neurotoxicity, including Parkinson-like extrapyramidal symptoms, when used in high doses.
Cardiovascular ...Chronic occupational exposure to manganese dust or fumes can cause orthostatic hypotension, and heart rate and rhythm disturbances (61363).
Endocrine ...Chronic occupational exposure to manganese dust or fumes can cause elevations in thyrotropin-releasing hormone (TRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels (61378).
Hepatic ...Manganese intoxication may cause cirrhosis and hepatic steatosis. In one case, a 13-year-old female with manganese intoxication developed severe, life-threatening neurological symptoms, with liver biopsy indicating incomplete cirrhosis and microvesicular steatosis. Chelation therapy and multiple rounds of therapeutic plasma exchange were required before symptoms resolved. The source of manganese exposure was not identified, and it is not clear if the impaired liver function contributed to the manganese accumulation or if elevated manganese exposure led to the liver damage.
Musculoskeletal ...Chronic occupational exposure to manganese dust or fumes has been associated with lower bone quality in females, but not males, suggesting that prolonged manganese exposure might increase the risk of osteoporosis in females (102516). A meta-analysis of 11 observational studies in adults also suggests that increased environmental exposure to airborne manganese sources is associated with lower motor function scores (108537).
Neurologic/CNS
...Orally, there is concern that higher doses of manganese might increase the risk of neurotoxicity, including Parkinson-like extrapyramidal symptoms (7135,10665,10666).
One severe case of irreversible Parkinson disease possibly related to taking manganese 100 mg daily for 2-4 years has been reported (96418). In another case, a 13-year-old female with manganese intoxication (diagnosed from blood manganese levels and cranial MRI evidence) developed severe neurological symptoms including loss of consciousness, decorticate posture, clonus, increased reflexes in the extremities, isochoric pupils, and no painful stimulus response. Liver biopsy also showed incomplete cirrhosis and microvesicular steatosis. The patient was intubated, and chelation therapy and multiple rounds of therapeutic plasma exchange were required before symptoms resolved. The source of the child's manganese exposure was not identified (112137). Individuals with impaired manganese excretion can also experience these effects even with very low manganese intake. Manganese accumulation due to chronic liver disease seems to cause Parkinson-like extrapyramidal symptoms, encephalopathy, and psychosis (1992,7135). One review recommends stopping supplementation if aminotransferase or alkaline phosphatase levels rise beyond twice normal (99302).
Chronic occupational exposure to manganese dust or fumes can also cause extrapyramidal reactions (1990,7135). In 1837, Couper observed that exposure to manganese dust particles produces a neurological syndrome characterized by muscle weakness, tremor, bent posture, whispered speech, and excess salivation (61264). Additionally, observational research in children has found that elevated manganese levels detected in the hair and fingernails due to environmental exposure may be associated with impaired neurocognitive function or development (108535). A meta-analysis of 11 observational studies in adults also suggests that increased environmental exposure to airborne manganese sources is associated with lower cognitive function scores (108537).
Intravenously, manganese might increase the risk of neurotoxicity when administered at high doses or for an extended duration. Cases of Parkinson-like symptoms have been reported in patients receiving parenteral nutrition containing more than 60 mcg of manganese daily. Moderate MRI intensity uptake for manganese in the globus pallidus and basal ganglion areas of the brain has been shown in patients receiving parenteral manganese (96416,99302).
Psychiatric ...Chronic occupational exposure to manganese dust or fumes can cause mood disturbance and dementia (1990,7135). A case report describes a man who presented with confusion, psychosis, dystonic limb movements, and cognitive impairment after chronic industrial manganese exposure (99415). Symptoms of manganese toxicity from inhalational exposure develop slowly with initial fatigue and personality changes, progressing to hallucinations, delusions, hyperexcitability, Parkinson-like symptoms, dystonia, and dementia (99415). Additionally, observational research has found that chronic environmental exposure to manganese sources such as mining operations and various industrial processes may be associated with a greater risk for developing symptoms of depression (108536).
Pulmonary/Respiratory ...Chronic occupational exposure to manganese dust or fumes can cause acute chemical pneumonitis, pulmonary edema, or acute tracheobronchitis (61495).
General
...Orally, MSM is generally well tolerated.
Most Common Adverse Effects:
Orally: Bloating, diarrhea, gastrointestinal discomfort, nausea.
Dermatologic ...In rare cases, MSM has caused pruritus when taken orally (8574).
Gastrointestinal ...Orally, MSM may cause mild gastrointestinal discomfort, nausea, bloating, and diarrhea (8574,12469).
Immunologic ...Orally, MSM may increase allergy symptoms (8574).
Neurologic/CNS ...Orally, MSM may cause headache, fatigue, insomnia, and difficulty concentrating (8574,14335).
Ocular/Otic ...In a case report, a 35-year-old female presented with bilateral acute angle closure glaucoma, which resolved 4 days after discontinuing a multi-ingredient product. Although the product contained over 35 vitamins, minerals, and other ingredients, only MSM contained sulfur, which the authors suggest acted like a sulfa-drug to cause acute angle closure glaucoma (90613).
General
...Orally, New Zealand green-lipped mussel seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, acid reflux, diarrhea, flatulence, and nausea.
Serious Adverse Effects (Rare):
Orally: Hepatitis.
Dermatologic ...Generalized itching has occurred in one child using a lipid extract of New Zealand green-lipped mussel extract (94495).
Gastrointestinal ...Orally, New Zealand green-lipped mussel or lipid extract can cause reflux, abdominal pain, diarrhea, nausea, or flatulence (15055,15056,54177,54190,54191,94492,94494).
Hepatic ...Several cases of possible toxic hepatitis and granulomatous hepatitis have been reported for patients taking a specific New Zealand green-lipped mussel extract (Seatone) (54173,54182,54183). Liver function abnormalities have also been reported (94494).
Musculoskeletal ...Orally, two reports of gout have been associated with the use of freeze-dried New Zealand green-lipped mussel ) 3000 mg daily in clinical research (94492).
Renal ...Orally, fluid retention has been reported as an adverse effect of New Zealand green-lipped mussel (15055,54189).
