Straight answers

Is anything on this page medical advice?

No. It lists what each product contains, what it costs and what testing the brand publishes. It never says what you should take or how much. The dose per serving is the label's; the sample dosage is what the evidence page reports from studies, shown as a plain fact, not a recommendation. A doctor who knows your health can tell you whether a supplement suits you.

How did you choose these products?

Every product passed the same five checks, each made on the brand's own US site: one main ingredient at a stated dose (or one standard pairing, flagged), dose and form per serving stated, a price on the brand's own store, testing proof we could open (a certification found on the certifier's own register, or a batch lab report), and no FDA warning letter or recall for that product. Where a brand passes with several products for one ingredient, we show its lowest cost per 30 days, leaving out anything on sale or sold out when we checked. Products that failed a check aren't listed. Each table is ordered by cost per 30 days, not ranked.

Checked Oct 31, 2026

How is "per 30 days" worked out?

The one-off price for one container, divided by its servings, times 30, using the serving size on the label. Subscription prices are shown underneath but not used for the order. We use the everyday price on the brand's own store, never a sale price or a "was" price.

What do the testing labels mean?

Certified: the product is listed on the certifier's own register (for example NSF Certified for Sport). Batch report, named lab: the brand publishes a lab report for a batch that names the lab and gives a figure for the main ingredient. Batch report, lab not named: the brand publishes a batch report with a figure for the main ingredient, but the lab's name is missing or blacked out. Where a report has a gap (no batch number, a figure below the label, two labs giving different figures), we say so under the product. A test report shows what's in a batch; it isn't evidence the ingredient works. That's what the tiers are for.

Does any brand pay to be on this page?

No. No brand pays to be listed or for a better position, and nothing a brand does can change which products are shown or their order. How we check, and our disclosure.
