HelloPharmacist Scorecard of TripleFlex by Nature Made
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
TripleFlex contains four active ingredients. Sodium is an essential mineral that helps regulate fluid balance and nerve function, though the amount in supplements needs careful consideration if you're on certain medications.
Methylsulfonylmethane (MSM) is an organic sulfur compound. Chondroitin Sulfate and Glucosamine Hydrochloride are both building blocks that naturally occur in cartilage and connective tissue, commonly used together in joint-support formulas.
Does it work?
Strong evidence
Glucosamine Hydrochloride is likely effective for osteoarthritis. Chondroitin Sulfate is possibly effective for osteoarthritis and cataracts.
Sodium's effectiveness has been rated for cystic fibrosis (likely effective) and amphotericin B-related kidney damage (possibly effective), though these are specialized medical uses. For the other conditions in the data — aging skin, osteoporosis, high cholesterol, colorectal adenoma, back pain, bipolar disorder, and congestive heart failure — the evidence we hold is insufficient to rate.
We have no effectiveness data for Methylsulfonylmethane.
How safe is it?
Well-documented data
Glucosamine and chondroitin are generally well tolerated by most adults, though they can cause digestive side effects like bloating, constipation, diarrhea, heartburn, and nausea. Rare reports exist of allergic reactions, including severe ones, and asthma flare-ups with glucosamine-chondroitin combinations.
Sodium is essential in small amounts, but excess intake is linked to high blood pressure and heart strain; supplemental sodium should be avoided without medical guidance. Avoid both glucosamine and chondroitin during pregnancy — there isn't enough safety information.
Similarly, avoid both while breastfeeding unless your doctor advises otherwise. Pregnancy and lactation safety data are not on file for sodium or Methylsulfonylmethane in this product.
Meds to double-check
Major interaction found
Check these medication types before taking TripleFlex: blood thinners (warfarin) — Major risk of increased bleeding; blood pressure medications; lithium; corticosteroids; certain chemotherapy drugs (topoisomerase II inhibitors); diabetes medications; and acetaminophen. Also check any sodium-containing drugs, including didanosine, sodium phosphate laxatives, and tolvaptan.
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.
TripleFlex may help with osteoarthritis if you're an adult without blood clots or blood thinner medications. If you take warfarin, blood pressure drugs, lithium, corticosteroids, or any sodium-containing medication, you must check with your pharmacist before starting this product.
Pregnant or breastfeeding women should avoid it. Talk to your pharmacist about your full medication list.

TripleFlex by Nature Made Drug Interactions
HelloPharmacist Interaction Report
TripleFlex by Nature Made contains ingredients with documented interactions affecting multiple medication types.
Sodium is the primary concern — it can reduce the effectiveness of blood pressure medications (antihypertensives) and may dangerously raise sodium levels if you're also taking corticosteroids, lithium, didanosine, sodium phosphate laxatives, tolvaptan, or other sodium-containing drugs. All of these interactions are Moderate severity.
Read the full breakdown — every affected drug type, severity by severity
Glucosamine Hydrochloride carries a Major interaction with warfarin (a blood thinner), significantly increasing bleeding risk. It also has Moderate interactions with certain chemotherapy drugs (topoisomerase II inhibitors like etoposide and doxorubicin) and Minor interactions with diabetes medications and acetaminophen.
Chondroitin Sulfate has one documented Moderate interaction with warfarin, though the effect of chondroitin alone — versus chondroitin combined with glucosamine — remains unclear. Methylsulfonylmethane could not be checked; we hold no interaction data for it.
Altogether, these interactions span 372 individual medications. Before you start TripleFlex, use the medication checker on this page to verify your exact prescriptions.

For each ingredient in TripleFlex with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Sodium
Antihypertensive Drugs
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.
Corticosteroids
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.
Didanosine (Videx)
Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.
Lithium
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
Sodium Phosphates
Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.
Sodium-Containing Drugs
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
Tolvaptan (Samsca)
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.
Glucosamine Hydrochloride
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.
Chondroitin Sulfate
Warfarin (Coumadin)
Taking chondroitin in combination with glucosamine might increase the anticoagulant effects of warfarin. However, the effect of chondroitin alone is unclear.
There have been multiple reports of increased international normalized ratio (INR) in patients taking warfarin with glucosamine, with or without chondroitin. The lack of reports with chondroitin alone seem to suggest that the interactions occurring in these reports may have been due to glucosamine. In two individual case reports, glucosamine/chondroitin combinations were associated with a significant increase in INR in patients previously stabilized on warfarin. Additionally, 20 voluntary case reports to the US 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, without chondroitin, to increased INR in patients taking warfarin.
