HelloPharmacist Scorecard of Double Strength SAM-e 400 mg by Puritan's Pride

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

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), a compound your body naturally makes that plays a role in mood, joint health, and liver function. Each dose delivers 400 mg.

The remaining ingredients—vegetable cellulose and polymethacrylate—are inactive components that form the capsule.

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: supports mood and joint function.
  • We looked for evidence on: Depression, Fibromyalgia, Osteoarthritis, emotional well-being, joint comfort.
  • The strongest evidence on file: Same is rated "Likely Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Same is rated "Possibly Effective" for Depression.
  • Also on file: Same is rated "Insufficient Reliable Evidence To Rate" for Fibromyalgia.

SAMe is likely effective for osteoarthritis pain and stiffness. It's possibly effective for depression and for liver conditions involving bile flow problems (cholestasis).

For Alzheimer disease and ADHD, there isn't enough reliable evidence in our data to rate how well it works. If you're considering SAMe for any of these conditions, talk it over with your doctor to see if the evidence fits your situation.

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 in typical doses, though side effects become more common at higher doses. The most frequent ones are stomach-related—nausea, diarrhea, constipation, vomiting, and heartburn—plus headache, insomnia, dizziness, and dry mouth.

A caution: SAMe can trigger mania in people with bipolar disorder, so it's not appropriate if you have that condition. The safety data for long-term use isn't well established, so use it only under the guidance of your own healthcare provider.

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 own doctor or pharmacist if you take serotonergic drugs (antidepressants like SSRIs, SNRIs, or tricyclics; migraine drugs like triptans; or pain medications like tramadol)—SAMe may raise the risk of serotonin syndrome. Also check if you take levodopa for Parkinson disease, since SAMe may reduce how well it works.

Check your own medication Run your meds through the checker above

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 if you have osteoarthritis or depression, but it's not for everyone. Steer clear if you take serotonergic drugs or levodopa without checking first—the interactions can be serious.

If you have bipolar disorder, don't use it. Talk with your doctor or pharmacist before starting to make sure it fits your health picture.

General Statements

Supports mood & emotional well-being* Promotes healthy joint function & comfort*

SAM-e is a revolutionary supplement. Because of its popularity and use, it has received widespread exposure in the press. Information has appeared in newspapers, magazines, on the Internet, or simply through word of mouth. Whether you’re a first-time SAM-e user, or have been a fan for years, you probably have some questions. Please see the enclosed package insert for more information.

All living things contain SAM-e (S-adenosylmethionine). The body makes SAM-e from the amino acid methionine. However, you may not be able to obtain sufficient methionine levels simply by ingesting food. In addition, because of age or other factors, levels of SAM-e can fluctuate or decline. Supplementation with SAM-e is the easiest way to increase intake.

SAM-e is involved in over 35 biochemical reactions involving enzymatic transmethylation.* The methylation process is the mechanism by which the body rids itself of unwanted compounds, synthesizes neurotransmitters, nourishes cartilage, regulates enzyme activity within the cell and helps maintain the flexibility of cell membranes.* Science has been looking into this remarkable supplement and have found, SAM-e: ~ Supports mood and emotional well-being* ~ Promotes healthy joint function and comfort*

SAM-e (S-adenosylmethionine) was discovered in Italy in 1952. The subject of extensive studies, SAM-e has been used in Europe since 1975. It was one of Europe’s best kept secrets until recently, when it became available in the U.S. SAM-e helps promote a positive mood and emotional well-being.* A note about our enteric coating: The enteric coating helps the breakdown of SAM-e occur in the small intestine. In addition, the enteric coating is designed to protect SAM-e from moisture and serve as a protective barrier so that SAM-e can be absorbed where it can provide you with the greatest benefits.

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.
