Amanita muscaria (fly agaric)

Tier 4 — risky / avoid · Neurotoxin · Psychoactive · Unpredictable

A toxic mushroom increasingly promoted on social media as a microdosing supplement for sleep and anxiety. Contains ibotenic acid and muscimol, which cause unpredictable psychoactive effects ranging from sedation to delirium, seizures, and coma. Potency varies wildly between individual mushrooms, making dosing impossible to control safely. Multiple poisoning cases reported annually. No clinical trial evidence supports any health benefit.
