Allithiamine (thiamine allyl disulfide or TAD) is a lipid-soluble derivative of vitamin B₁ which was discovered in garlic (Allium sativum) in the 1950s along with its homolog prosultiamine.^[1] They were both investigated for their ability to treat Wernicke–Korsakoff syndrome and beriberi better than thiamine.^[2]
