How to Choose a SAMe Supplement
Keep tablets sealed in foil blisters; check actual SAMe, not salt weight.
Research ranges: mood 800–1,600 mg/day; joints 600–1,200 mg/day. Seek dosing guidance.

Avoid MAOIs. Antidepressants, tramadol, dextromethorphan and St. John’s wort require prescriber review for serotonin toxicity.
Insomnia, nausea and mania are risks; pregnancy data are inadequate. Confusion, fever or rigidity needs urgent care.
For context, I suggest how SAMe compares with St. John’s wort and other evidence-backed joint supplement options.
