HelloPharmacist Scorecard of Glucosamine and MSM by Divine Bounty
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains two active ingredients: glucosamine sulfate 2KCI and methylsulfonylmethane (MSM). Glucosamine is a compound derived from shellfish or made in a lab; it's meant to support joint structure and function.
MSM is a sulfur-containing compound sometimes used in joint support formulas. The capsule shell is vegetarian.
Does it work?
Strong evidence
Glucosamine sulfate is rated likely effective for osteoarthritis — the main reason people take it. For other uses listed here (aging skin, back pain, colorectal cancer prevention, and liver disease), the evidence we have isn't strong enough to rate it either way.
If you're taking this for osteoarthritis, it may help; for other reasons, talk with your doctor about whether the science supports it.
How safe is it?
Well-documented data
Glucosamine is generally well tolerated by most adults when taken by mouth. Common side effects are mild — bloating, constipation, cramps, diarrhea, heartburn, nausea.
Rare serious effects have been reported. There is also concern about allergic reactions in sensitive people; one review found that 72% of adverse reports involved hypersensitivity reactions, ranging from mild (itching, hives) to severe (difficulty breathing, low blood pressure), with anaphylaxis reported in 1.5% of cases.
Cases of asthma flare-ups have also been reported. Avoid this product during pregnancy — there isn't enough safety information.
During breastfeeding, the safety data is insufficient; don't use unless your doctor advises it's okay.
Meds to double-check
Major interaction found
Check with your doctor or pharmacist before using this product if you take warfarin or other blood thinners — glucosamine may increase bleeding risk. Also verify if you're on topoisomerase II inhibitors (cancer drugs like etoposide or doxorubicin), acetaminophen-containing products, or antidiabetes medications, as glucosamine can interact with each of these drug types.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This is mainly used for osteoarthritis, where the evidence supports it. If you take warfarin or certain cancer drugs, you need to discuss this with your doctor before starting — the interaction risk is real.
If you have a shellfish allergy or history of allergic reactions, be cautious. Talk it over with your own doctor or pharmacist before adding it to your routine, especially if you're on any blood thinners or medications.

Glucosamine and MSM by Divine Bounty Drug Interactions
HelloPharmacist Interaction Report
Glucosamine and MSM by Divine Bounty carries interaction concerns primarily through its glucosamine sulfate content.
The most serious is with warfarin (a blood thinner), where glucosamine may increase bleeding and bruising risk — two case reports showed significant increases in how long blood took to clot in patients previously stable on the drug.
Read the full breakdown — every affected drug type, severity by severity
Glucosamine also interacts with cancer drugs called topoisomerase II inhibitors (including etoposide and doxorubicin), where laboratory research suggests it might reduce their effectiveness, though this has not been seen in humans. It can interfere with pain relief from acetaminophen, and there are older concerns about its effects on blood sugar control — though current evidence suggests it's unlikely to significantly worsen diabetes or reduce antidiabetes medication effectiveness.
We could not check methylsulfonylmethane (MSM) — we hold no interaction data for it. Altogether, these interactions span 170 individual medications.

For each ingredient in Glucosamine and MSM with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Glucosamine Sulfate 2KCI
Warfarin (Coumadin)
Glucosamine might increase the anticoagulant effects of warfarin and increase the risk of bruising and bleeding.
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. 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. 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. 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. 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.
Topoisomerase Ii Inhibitors
Theoretically glucosamine may induce resistance to topoisomerase II inhibitors.
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. This effect has not been reported in humans.
Acetaminophen (Tylenol, Others)
Acetaminophen might interfere with the activity of glucosamine sulfate by interacting with the sulfate portion.
Anecdotal reports suggest that adding glucosamine to an acetaminophen regimen might decrease pain control in patients with osteoarthritis. 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.
Antidiabetes Drugs
Despite initial concerns, it is unlikely that glucosamine will interfere with the effects of antidiabetes drugs.
In vitro and animal research has suggested that glucosamine might increase insulin resistance or decrease insulin production. 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.
