Safety Profile

Overall safety rating: Safe with Caution

Potential Side Effects

  • Rapid tolerance development (primary limitation — effects diminish with daily use)
  • Insomnia if taken after midday
  • Irritability or agitation at higher doses
  • Headache (mitigated by choline co-supplementation)
  • Appetite suppression
  • Potential overstimulation in sensitive individuals

Drug & Supplement Interactions

  • Stimulants (caffeine, amphetamines) — additive stimulatory effects; use lower doses of both
  • Choline sources — recommended co-supplementation to prevent headaches

  • WADA-banned — prohibited in competitive athletics

Maximum Dose

Do not exceed: 300mg/day (tolerance develops rapidly with daily use)
