By The Supplement Ratings editorial team2,507 products analyzed

Nootropics and brain-support formulas are where marketing runs furthest ahead of labels: many products promise focus or memory and then hide their ingredients in a blend. The products at the top of this ranking state every amount, so you can compare them with the doses used in research.

This ranking covers phosphatidylserine, citicoline, alpha-GPC, bacopa, ginkgo and other brain-focused supplements sold on iHerb, ranked by label quality.

How we ranked them

Every product is scored 0–100 from its label data in the NIH Dietary Supplement Label Database: dosage transparency (35 points - are amounts stated per ingredient, or hidden in a proprietary blend?), label completeness (25), formulation cleanliness (25 - fillers, dyes, titanium dioxide and other non-active ingredients) and ingredient profile (15). The Top 10 admits only products scoring 60 or higher; among those, products with a verified retail listing are shown first so the list is one you can act on. No brand can pay to be included or moved up.

Forms and dosage

Choline sources (citicoline, alpha-GPC, choline bitartrate): Different compounds with different amounts of choline per milligram; the label should name the form.
Phosphatidylserine: A phospholipid, usually from soy or sunflower. The FDA allows only a qualified health claim for it, citing very limited evidence.
Herbal extracts (bacopa, ginkgo): Standardized extracts state the percentage of active compounds, such as bacosides or ginkgo flavone glycosides.
Multi-ingredient nootropic stacks: Often a long list under one blend weight. Each ingredient is usually below the studied dose.

How much to take

Doses used in studies, for comparison with the label: phosphatidylserine 100 mg up to three times a day, citicoline 250–500 mg, bacopa extract around 300 mg, ginkgo extract 120–240 mg. Choline has an adequate intake of 425–550 mg per day for adults and an upper limit of 3.5 g.

Frequently Asked Questions

Do nootropic supplements work?

Our score measures label quality, not outcomes. Evidence differs a lot between ingredients, and many stacks use doses below those in studies. A label that states every amount is the only way to check.

What is the difference between citicoline and alpha-GPC?

Both are choline sources used in brain-support products, at different amounts of choline per milligram. A clear label names the form and the amount.

How are brain & nootropics supplements ranked?

Products are ranked by SupplementScore, which evaluates label quality across four categories: dosage transparency (35 pts), label completeness (25 pts), formulation cleanliness (25 pts), and ingredient profile (15 pts). The score is based on data from the NIH Dietary Supplement Label Database, not marketing claims.

Does a higher score mean the supplement is more effective?

No. The SupplementScore measures label quality, how transparent, clean, and well-documented a product is. It does not measure clinical efficacy, bioavailability, or third-party testing. A higher score means better label practices, not guaranteed results.

How many brain & nootropics supplements were analyzed?

We analyzed 2,507 brain & nootropics products from the NIH DSLD database, which contains label data for over 116,000 dietary supplements sold in the United States.
