HelloPharmacist Scorecard of SAMe Joint by Jarrow Formulas
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Every active ingredient lists its own amount on the label.
Why this rating?
- The label discloses an exact amount for 2 of its 2 active ingredients.
- “S-Adenosyl Methionine” is listed as a grouped ingredient — the label gives one combined amount (200 mg) without saying how much of each component you get.
At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.
Why this rating?
- 2 of the 2 matched ingredients can interact with medications — Same, Glucosamine.
- The most serious interaction on file is rated Major.
- Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; Parkinson's medications.
- For scale: 335 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.
Why this rating?
- We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
- Pregnancy & breastfeeding safety ratings cover 2 of 2.
- General safety write-ups exist for 2 of 2.
- Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Formula
SAMe + Glucosamine
Full potency 200 mg SAMe (net yield) is derived from 400 mg of SAMe tosylate disulfate.
S-Adenosyl Methionine + Glucosamine 200 mg (net yield) SAMe 525 mg Glucosamine HCl Highest Concentration of Active S,S Form
Natural SAMe Joint Jarrow Formulas SAMe Joint provides a full 200 mg SAMe (net yield) and 525 mg of glucosamine hydrochloride in every enteric-coated tablet. SAMe Joint is manufactured under low temperature and low humidity and is enteric-coated to ensure a biologically active product. SAMe and glucosamine are known to benefit joint function and recuperation. Contains More of the Active S,S Form SAMe Found in all living cells, SAMe is a metabolite of methionine (an essential amino acid). SAMe is a chiral molecule consisting of two forms: (S,S) SAMe and (R,S) SAMe. The biologically active form is the (S,S) structure, while the (R,S) structure is biologically inactive. Jarrow Formula SAMe is made naturally by microbiological fermentation and then specially processed without chemical solvents to preserve 68-80% (S,S) SAMe, the highest active level available. Glucosamine Glucosamine is an aminosaccharide synthesized by transamidase enzymes from glucose and an amine group from glutamine. HCl (hydrochloric acid) stabilizes the glucosamine in this product. Glucosamine is a component of joint and intestinal tissue and is involved in the production of synovial fluid that lubricates the joints. SAMe has been clinically shown to have the following benefits: Joint Strength SAMe supports the production of healthy connective tissue through transulfuration. In this process, critical components of connective tissue, known as glycosaminoglycans (GAGs), including glucosamine and chondroitin, are sulfated by SAMe metabolites to yield sulfated GAGs, such as glucosamine sulfate and chondroitin sulfate. Brain Metabolism SAMe methylation reactions are involved in the synthesis of neurotransmitters such as L-DOPA, dopamine and related hormones, serotonin, epinephrine and phosphatidylcholine (a component of lecithin). Liver SAMe metabolism supports the synthesis of glutathione (GSH) and glutathione-dependent enzymes (glutathione peroxidase, glutathione reductase and glutathione-S-transferase), which are components of the body's endogenous antioxidant network and important for liver function, including phase II detoxification.

For each ingredient in SAMe Joint 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.
S-Adenosyl Methionine
Levodopa
SAMe might reduce the effectiveness of levodopa.
SAMe methylates levodopa, which might reduce its effectiveness for treating Parkinson disease.
Serotonergic Drugs
Taking SAMe with serotonergic drugs might increase the risk of serotonin syndrome and other serotonergic side effects.
SAMe has serotonergic effects. Theoretically, combining serotonergic drugs with SAMe might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders. In one case report, SAMe 100 mg intramuscularly was given daily with clomipramine (Anafranil) 25 mg per day. When the clomipramine dose was increased to 75 mg per day the patient experienced serotonin syndrome about 48-72 hours later, requiring hospitalization.
Glucosamine HCl
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.
