Frequently asked questions
Which is better, Mind Lab Pro or Alpha Brain?
Mind Lab Pro discloses every ingredient dose; Alpha Brain hides several behind proprietary blends. If formula transparency matters to you, Mind Lab Pro is the stronger choice. If you prefer a brand with broad retail distribution and a 15% subscription discount, Alpha Brain is the more accessible option.
Are Mind Lab Pro and Alpha Brain caffeine-free?
Both are caffeine-free. Mind Lab Pro is explicitly marketed as caffeine-free. Alpha Brain Classic is also caffeine-free; Onnit's Black Label and Instant variants include other ingredients you should check the label for.
How long until each takes effect?
Both contain ingredients with mixed onset profiles. L-theanine (in both) acts within 30–60 minutes. Bacopa Monnieri (in both) needs 4–12 weeks of consistent use for measurable cognitive effects. Plan for at least 8 weeks before judging long-term efficacy.
Do they offer money-back guarantees?
Mind Lab Pro: 30-day Performance Promise (money back if you finish the bottle and don't see a benefit). Alpha Brain: standard Onnit return window.
Which is better value for money?
Mind Lab Pro is $69/month at full price. Alpha Brain is $79.95 for a 90-count bottle, which Onnit calls a 45-day supply (checked 7 October 2026). Mind Lab Pro costs more but offers a fully open formula. Alpha Brain is cheaper but several active ingredients sit inside undisclosed proprietary blends.
Are these alternatives to Adderall?
No. Mind Lab Pro and Alpha Brain are dietary supplements regulated under DSHEA. Adderall is a Schedule II prescription stimulant for ADHD. The two are not equivalent and supplements should not be marketed as replacements for prescription medication. Always consult a clinician for ADHD treatment.
