Apricot Kernels
Apricot kernels — particularly bitter varieties — contain amygdalin, which releases cyanide upon digestion. EFSA established a safety threshold and FDA has warned consumers; multiple cases of acute cyanide poisoning have been documented from supplements and raw kernels marketed as cancer cures.
What it is
The seeds inside apricot pits (Prunus armenicus), containing the cyanogenic glycoside amygdalin.
Used in marzipan-like pastes (bitter apricot kernels) and folk-medicine supplements; sweet kernels used in confectionery.
Why it's flagged
- cyanide poisoning risk from amygdalin
- FDA/EFSA warnings against high consumption
- lethal dose can be reached with small numbers of bitter kernels
What regulators actually say
"Adults should not consume more than three small raw apricot kernels at a time; consumption of more than this can lead to acute cyanide poisoning."
"Laetrile/amygdalin... has not been shown to be safe or effective for the treatment of any condition; products containing amygdalin pose a serious risk to consumers."
Regulatory status
United States — FDA
FDA has warned against laetrile/amygdalin supplements; not approved as a drug.
European Union — EFSA
EFSA recommends max single intake of 20 mcg cyanide/kg bw — about 1-3 small kernels for adults.
