Marketing Claims Vs. Reality
Clinically studied Synapsa.
The panel names Synapsa, the trademark for the CDRI 08 whole-plant extract used in the Stough 2001 and 2008 and Morgan 2010 trials, at the 320 mg dose.
Standardized to 55% bacosides.
Printed on the Supplement Facts panel.
Non-GMO, vegan, gluten and soy free.
All four marks appear on the panel; the capsule is hypromellose.
What Our Test Actually Found
The extract, the dose and the number
Nootropics Depot sells the same Synapsa extract but its panel prints no bacoside percentage. Doctor's Best prints 55 percent, uses a vegan capsule and costs less. That combination is why it wins.
Testing is stated by the brand, not printed
Doctor's Best manufactures under GMP, but the panel carries no third-party or lab statement. For a field-grown herb that is the one gap on an otherwise complete label.

Synapsa is the commercial name of the CDRI 08 extract behind the twelve-week memory trials, and 320 mg a day is the studied dose. Doctor's Best gives you exactly that, tells you it is 55 percent bacosides, uses a vegan capsule and charges less than the specialist vendor selling the same extract. Only the absence of a third-party testing statement on the panel keeps it from a higher score.
Doctor's Best sells the extract the trials were run on and, unlike the other Synapsa capsule here, prints its standardization: 320 mg Bacopa monnieri whole-plant extract as Synapsa, standardized to contain 55 percent bacosides, one veggie capsule a day, 60 servings. Other ingredients are hypromellose, microcrystalline cellulose, silicon dioxide and magnesium stearate; gluten-free, non-GMO, vegan and soy-free marks are on the panel. The label names Soho Flordis International as the Synapsa trademark holder.
The Bacopa to buy: trial extract, trial dose, number printed
If you take bacopa for the memory effect the trials measured, this is the capsule that most closely reproduces them, and it says so on the panel. Take one a day with food for at least twelve weeks; that is how long the studies ran.
If This Doesn’t Fit — Try These
02Swanson BaCognize
If the trial extract matters and the price matters more, Swanson's BaCognize gets you both for about twenty cents a day.
03Nootropics Depot Synapsa
If who tested it matters most, this is the bacopa to buy.
04Nutricost 1,000 mg
A well-labelled, tested, vegetarian bacopa whose serving size ignores the trials.
Quick Answers
What is Synapsa?
The commercial name of the CDRI 08 Bacopa monnieri whole-plant extract developed in India and used in the twelve-week memory trials. Doctor's Best supplies it at 320 mg standardized to 55 percent bacosides per capsule.
How long until bacopa works?
The trials measured memory gains at twelve weeks, not before; Stough 2001 found no effect at five weeks. Plan on one capsule a day for three months with food, since bacopa on an empty stomach commonly causes nausea.
