Doctor's Best SAM-e Double Strength Supplement

Our verdict

Doctor's Best SAM-e Double Strength Supplement works out to $0.82 per serving of sam-e, at 400mg per serving in tablet form. That puts it above the median of the 24 sam-e products we can price per dose, where the typical serving costs $0.50, a Value Index of 0.6 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $24.50 a month. We could not verify a third-party certification for Doctor's BEST in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
