HelloPharmacist Scorecard of Double Strength SAM-e 400 mg by CVS Health

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 23, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: S-Adenosylmethionine (SAMe), dosed at 400 mg per serving. SAMe is a compound your body makes naturally and uses in many cellular processes, including mood regulation and joint health.

The inactive ingredients are cellulose and polymethacrylate, which are common binders and fillers that help form the tablet.

Does it work?

Strong evidence
Evidence for Intended Use · database check
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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: mood, emotional well-being, liver and joint health.
  • We looked for evidence on: Depression, Osteoarthritis, Fibromyalgia, Cirrhosis, Hepatitis C, Alcohol-related liver disease — and 4 related terms.
  • The strongest evidence on file: Same is rated "Likely Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Same is rated "Possibly Effective" for Cholestasis, Depression.
  • Also on file: Same is rated "Insufficient Reliable Evidence To Rate" for Alcohol-related liver disease, Cirrhosis, Fibromyalgia, Hepatitis C.

SAMe is likely effective for osteoarthritis — the research supports its use for joint pain and stiffness. It's possibly effective for depression and for a liver condition called cholestasis.

For Alzheimer disease and ADHD, there isn't enough reliable evidence yet to say whether it works.

The evidence, ingredient by ingredient Same

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

SAMe is generally well tolerated when taken at standard doses, though side effects become more common at higher doses. The most frequent ones are stomach upset (nausea, diarrhea, constipation), headache, dizziness, dry mouth, insomnia, and nervousness.

Some people also report sweating, flatulence, or vomiting. One important caution: SAMe can trigger mania in people with bipolar disorder, so if you have that condition, talk with your doctor or pharmacist before taking it.

Safety data is limited, so use it only under healthcare provider guidance.

Side effects, ingredient by ingredient Same

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Same.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: Parkinson's medications.
  • For scale: 189 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.

Before taking this product, check with your doctor or pharmacist if you take serotonergic drugs (such as SSRIs, SNRIs, or tramadol) — SAMe may increase your risk of serotonin syndrome. Also check if you take levodopa for Parkinson disease, since SAMe may make it less effective.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

SAMe may help with osteoarthritis pain and possibly with depression, but it does interact with common medications — especially antidepressants and Parkinson drugs. If you take any serotonergic medication or levodopa, check with your doctor or pharmacist before starting.

It's generally well tolerated but can cause stomach upset and may be risky if you have bipolar disorder.

Levodopa

SAMe might reduce the effectiveness of levodopa.
SAMe methylates levodopa, which might reduce its effectiveness for treating Parkinson disease.

Likelihood Possible Evidence D
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.

Double Strength SAM-e 400 mg by CVS Health: Common Questions

Does Double Strength SAM-e 400 mg by CVS Health interact with any medications?
Yes. Based on its ingredients, Double Strength SAM-e 400 mg has a known interaction with 189 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Double Strength SAM-e 400 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is SAMe safe to take if I'm pregnant?
The data we hold shows SAMe is possibly safe in pregnancy, but safety isn't fully established. Talk with your doctor or pharmacist about whether it's right for you — they can weigh the benefits and risks based on your individual situation.
What are the most common side effects?
Stomach problems are the main ones — nausea, diarrhea, or constipation. You might also feel dizzy, have a headache, dry mouth, insomnia, or nervousness. These tend to happen more at higher doses and usually settle down with continued use, but tell your doctor or pharmacist if they bother you.
Can SAMe help with depression?
SAMe is possibly effective for depression based on the evidence we have, though it's not as well studied as many prescription antidepressants. If you're interested in trying it, talk with your doctor first — especially if you already take antidepressants, since SAMe can interact with them.
Will SAMe work if I have Parkinson disease and take levodopa?
SAMe may actually reduce how well levodopa works, so it's not a good fit alongside that medication. If you have Parkinson disease, check with your doctor before taking SAMe.
Is this safe if I have bipolar disorder?
No — SAMe can trigger mania in people with bipolar disorder. If you have bipolar disorder, talk with your doctor or pharmacist before considering this product.
Does this product have any fillers?
Yes, it contains cellulose and polymethacrylate as binders. These are standard inactive ingredients used to hold the tablet together.
