YSK Omega 3 Fish oil supplement capsules can cause horrendous Body Odor if they've gone rancid.
Why YSK: People often misjudge people m with BO (body odor) as being poorly disciplined with their personal hygiene. They judge people harshly often for smelling bad.
An Internet search I did returned this info:
"Rancid fish oil can lead to unpleasant body odors, including a fishy smell, due to the oxidation of omega-3 fats in the oil. This oxidation can produce compounds that may be released through sweat and breath, resulting in a condition known as trimethylaminuria, or fish odor syndrome."
