“Nootropic” is a loose word for things people take with thinking in mind: plant extracts, amino acids, vitamins and minerals. A stack is several of them in one capsule.

Coffee is the one most people already use. Some stacks add caffeine. Ours has none.

Three things to look for

  • A dose for every ingredient. A label that prints one “blend” total cannot tell you how much of anything you are taking.
  • Standardised extracts. “Bacopa” says which plant. “Bacopa, 45% bacosides” says how strong.
  • Whether there is caffeine in it. Some stacks add it. You may already have had enough.

What two capsules give you

  • Zinc, 10 mg. Contributes to normal cognitive function.
  • Vitamin B6, 5 mg. Contributes to the reduction of tiredness and fatigue, and to the normal functioning of the nervous system.

The ten in Brain Tech

  • Gotu kola, 250 mg. A leafy herb used in South and South-East Asian kitchens.
  • Panax ginseng, 240 mg. The root, used in East Asia for centuries.
  • Choline bitartrate, 210 mg. Gives 84 mg of choline.
  • L-theanine, 196 mg. An amino acid from green tea leaves.
  • Bacopa, 150 mg. A creeping herb, standardised to 45% bacosides.
  • Phosphatidylserine, 100 mg. A phospholipid.
  • Rhodiola, 25 mg. The root of a plant from cold, high places.
  • Zinc, 10 mg, and vitamin B6, 5 mg. 100% and 357% of the daily reference values.
  • Black pepper extract, 5 mg. Standardised to 95% piperine.

There is no caffeine and no guarana. The capsule is plant-based.
