Who should not take Urolithin A (Mitopure)
- Pregnant or breastfeeding individuals — most nootropics have not been adequately studied in pregnancy, and the precautionary principle applies.
- Anyone on a prescription medication that overlaps mechanistically (stimulants, SSRIs, MAOIs, beta-blockers, anticoagulants) — clear interactions with your prescribing clinician before adding Urolithin A (Mitopure).
- Anyone with significant cardiovascular, hepatic, renal, or psychiatric disease — established conditions raise the baseline risk for any new compound.
- Minors — almost no nootropics have a paediatric safety record, and developing brains are differently sensitive.
What "safe" means here
Our safety scoring reflects (a) published clinical and observational literature on healthy-adult use at standard supplement doses, (b) the spectrum of adverse-event reports in the medical and supplement-pharmacovigilance record, and (c) the regulatory status across major jurisdictions. It does notreflect long-term outcomes in populations that haven’t been studied, and it does not substitute for clinical judgement applied to your individual situation.
A 5/5 score does not mean “no risk” — it means risk has been quantified as low in healthy adults at usual doses. Idiosyncratic and allergic reactions are possible with virtually any compound, including those we rate highest.
