Synaptril

Memory & focus · 60 capsules · 30-day supply

4 of 6 actives at studied dose 2 underdosed No proprietary blend

A well-dosed caffeine-and-theanine base with a bacopa dose that matches the trials. The ginkgo and huperzine additions aren't earning their place.

Buy it if

You want caffeine + L-theanine at a sensible ratio in one capsule.
You'll take it daily for at least eight weeks, for the bacopa.
You value a full label over a cheaper blend.

Skip it if

You're sensitive to caffeine, or already drink coffee — you'd be stacking.
You only want bacopa; single-ingredient costs less.
You're on an SSRI or blood thinner — check with your doctor first.

The label, line by line

Each dose compared with the amount used in the trials we rate it on.

Ingredient In Synaptril Studied dose Verdict

Caffeine (anhydrous) 100 mg 75–200 mg At dose

L-theanine 200 mg 100–250 mg At dose

Bacopa monnieri (50% bacosides) 320 mg 300–450 mg At dose

Ginkgo biloba 60 mg 120–240 mg Underdosed

Huperzine A 50 mcg 200–400 mcg Underdosed

"Studied dose" is the range used in the trials we cite on each ingredient page. A dose below that range is not necessarily useless — it is unevaluated, which is not the same thing as effective.

Where to buy it
