Not enough information on exactly what is being taken—8 grams of powdered curcumin, which is the pigment in Tumeric? How much enters the blood as active material? Is per-emptive use a better option, than last resort?

As said, there are ways of enhancing absorption of curcumin by compounding with other ingredients. Here is one supplier that is often recommended.
“Terry Naturally’s CuraMed is a blend of three targeted ingredients that is believed to promote the body’s healthy internal response. This tissue-support formula includes curcumin (BCM-95), phospholipids and turmeric essential oil. BCM-95 is a scientifically researched, highly absorbable curcumin formula. Study results showed blood levels of BCM-95 at 10 times the levels of other curcumin products two hours after ingestion.”
I have heard it is pointless to take turmeric without piperine from pepper. The supplement link in my previous definitely has that assist to help the body take in the nutrients.
