Medical disclaimer

This is education, not care

Every article, review, and tool here is published for general informational and educational purposes. Reading it does not create a clinician–patient relationship between you and Clearhead Lab, its editor, or anyone who contributes to it. We do not practice medicine, we do not diagnose, and we cannot tell you what is safe or effective for your particular body, history, or goals. Treat what you find here as a well-sourced starting point for a conversation with a professional, not as a stand-in for one.

Talk to a clinician before you change anything

A licensed clinician who can review your medical history, current medications, and lab work is the right person to decide whether a given nootropic, supplement, or treatment belongs in your routine. Please speak with one before you start, stop, or adjust anything you read about here, including how you take a product you are already using.

Note: what worked well in a study, or for someone whose story sounds like yours, is not a prediction about you. Responses to cognitive compounds vary widely from one person to the next, and individual results can differ from any figure or summary we cite.

In an emergency

Nothing on this site is built for urgent situations, and it should never delay real help.

Important: if you think you are having a medical emergency — chest pain, trouble breathing, a severe reaction, thoughts of harming yourself, or anything else that frightens you — call 911 or your local emergency number, or go to the nearest emergency department right away.

About nootropics and supplements specifically

The cognitive category is unusually easy to misread, so a few caveats deserve to be spelled out. Dietary supplements are regulated differently from medicines: they are not reviewed or approved by the U.S. Food and Drug Administration to diagnose, treat, cure, or prevent any condition, and any statement we make about them carries that same limit.

Note: some of the compounds discussed in the wider cognitive-enhancement conversation are prescription-only. Those require an evaluation and a prescription from a licensed prescriber, and they are not something to source or self-administer on the strength of an article.

Stimulants and stimulant-like ingredients carry their own cautions, and many cognitive products can interact with medications, existing conditions, pregnancy or breastfeeding, or one another. If you are managing a health condition or taking anything regularly, treat interaction risk as a question for your clinician or pharmacist rather than something to reason through alone.

Third-party information and vendors

We sometimes describe products, brands, and services offered by other companies, and we may reference labeling, pricing, or claims those companies publish. Mentioning a vendor is not an endorsement of it, and we do not control or guarantee what happens once you deal with a third party. Their own terms, privacy practices, and medical guidance apply to your relationship with them.

On accuracy

We tie our claims to primary research or official labeling and we try to keep pages current, but the science moves, products change, and errors happen. We make no guarantee that everything here is complete, current, or free of mistakes, and we cannot be responsible for decisions made on the basis of the content alone. If you notice something that looks wrong or out of date, we would genuinely like to hear about it.
