Onnit Alpha Brain, Memory & Focus 30 Caps

What's in Onnit Alpha Brain?

Each two-capsule serving gives 10 mg vitamin B6 plus three blends: Flow (650 mg: L-tyrosine, L-theanine, oat straw extract, phosphatidylserine), Focus (240 mg: Alpha GPC, bacopa extract, Huperzia serrata extract) and Fuel (60 mg: L-leucine, pterostilbene). It also lists 350 mg of cat's claw bark extract.

What can Alpha Brain actually claim to do?

Only what its vitamin B6 allows: vitamin B6 contributes to normal psychological function and to the reduction of tiredness and fatigue. The botanicals and amino acids in the blends have no authorised health claims in Great Britain, so we don't make any for them.

How do I take it, and how long does a bottle last?

Two capsules a day, preferably with a meal. The 30-capsule bottle is 15 days' supply, and the 90-capsule Alpha Brain bottle we also sell lasts 45 days.

Does Alpha Brain contain caffeine?

No. Onnit makes the classic Alpha Brain capsules without caffeine, so it won't add to your daily caffeine intake.

Can I take it with a multivitamin or B-complex?

Check the vitamin B6 first: two capsules provide 10 mg, and the NHS advises not taking more than 10 mg of vitamin B6 a day from supplements unless a doctor advises it. Avoid stacking it with other B6-containing products.

Is it suitable for vegetarians?

The capsule is vegetarian (hydroxypropyl methylcellulose), and the other ingredients listed are maltodextrin, dicalcium phosphate and rice hull concentrate. Onnit doesn't state vegan certification on our listing, so check the pack if that matters to you.

Who should avoid it?

Speak to a doctor first if you're pregnant or breastfeeding, have or suspect a medical condition, or take any medication; that's the label's own advice. Alpha Brain is for adults, so keep it out of reach of children.
