I believe the most beneficial compounds in Tumeric are the curcuminoids. Curcumin supplements are very common but there are different types. The most common being:

C3 Complex - Curcumin with black pepper. This is cheap and effective but can cause medication interactions due to the black pepper.

Longvida - Increases curcumin absorbtion by over 200x. Used in studies for Alzheimers.

Mervia - Another highly absorbed curcumin supplement. Mostly researched in anti-inflammatory studies.

I personally use Longvida. Happy supplementing Steemians.
