HelloPharmacist Scorecard of Glucosamine + Chondroitin 1350 mg by Nature's Answer
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 2 active ingredients: glucosamine and chondroitin, both compounds found naturally in cartilage. Glucosamine is believed to support joint structure and function, while chondroitin may help cartilage retain water and resist compression.
The capsule also contains inactive ingredients—vegetable cellulose, rice flour, and calcium silicate—which serve as fillers and binders.
Does it work?
Strong evidence
Glucosamine is rated likely effective for osteoarthritis. For other uses listed—aging skin, back pain, colorectal cancer, and metabolic dysfunction-associated steatotic liver disease—the evidence we hold is insufficient to establish whether it works.
Talk with your doctor about whether this product is appropriate for your specific condition.
How safe is it?
Well-documented data
Glucosamine taken by mouth is generally well tolerated by most adults. The most common side effects are mild and digestive: bloating, constipation, cramps, diarrhea, heartburn, and nausea.
Rare serious adverse effects have been reported orally, and there is some concern about allergic reactions—one review found that about 7 in 10 glucosamine-related adverse events involved hypersensitivity reactions, ranging from mild (itching, rash) to severe (difficulty breathing, low blood pressure), with anaphylaxis reported in a small number of cases. Cases of asthma flare-ups have also been reported.
During pregnancy, there isn't enough safety information, so the data advises against use. Similarly, safety while breastfeeding isn't well established—avoid unless your doctor advises otherwise.
If you have a known allergy or sensitivity to glucosamine, shellfish, or any ingredient in this product, talk with your pharmacist before taking it.
Meds to double-check
Major interaction found
Before you take this product, double-check with your doctor or pharmacist if you take warfarin or any blood thinner—glucosamine may increase bleeding risk (Major interaction). Also confirm if you're on cancer chemotherapy, especially etoposide or doxorubicin; diabetes medications; or regular acetaminophen.
Altogether, these interactions span 170 individual medications.
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 product may help with osteoarthritis if you're an adult with no major health concerns or medications. If you take warfarin or any cancer chemotherapy, or if you have diabetes or take acetaminophen regularly, check with your doctor or pharmacist first.
Pregnant women and those breastfeeding should avoid it unless their doctor says otherwise. Quality and benefit vary between brands, so discuss whether this is the right choice for you.

Glucosamine + Chondroitin 1350 mg by Nature's Answer Drug Interactions
HelloPharmacist Interaction Report
Glucosamine + Chondroitin 1350 mg by Nature's Answer does interact with several medication types, most seriously through its glucosamine content with blood thinners.
Glucosamine might increase how warfarin (an anticoagulant) works in your body, raising the risk of bruising and bleeding—case reports have shown significant increases in blood-thinning levels in patients who were previously stable on the drug.
Read the full breakdown — every affected drug type, severity by severity
Glucosamine also has documented interactions with cancer chemotherapy drugs (topoisomerase II inhibitors like etoposide and doxorubicin), though this concern is mainly theoretical from lab research and hasn't been seen in patients yet. It may also have minor interactions with diabetes medications and acetaminophen (Tylenol), though the diabetes concern is considered unlikely in practice, and the acetaminophen interaction may reduce pain relief in osteoarthritis.
We could not check chondroitin for interactions—we hold no data for that ingredient. Before you start this product, run your exact medications through the checker on this page, or talk with your doctor or pharmacist about whether it's right for you, especially if you take a blood thinner or cancer drug.

For each ingredient in Glucosamine + Chondroitin 1350 mg 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
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.
