Turmeric & Memory: The 18-Month Trial

Turmeric · ขมิ้น · Curcuma longa

Turmeric — ขมิ้น (kha-min) — Curcuma longa.

In an eighteen-month controlled trial, a lipidated curcumin supplement improved memory and attention scores in older adults. The study tested a formulated curcumin supplement. The edible rhizome provides manganese, iron, and fiber. Southern Thai cooks use it in yellow curry, Gai Tod Khamin, and Khao Mok Gai. Fat and black pepper can increase curcumin absorption. A curry produces a different exposure from the tested supplement. Talk to your doctor before taking high-dose curcumin supplements; ordinary cooking uses much smaller amounts.
