I got an email from Healthspan recently pushing their version.
Rubbished the BBC because you need a lot of powdered Turmeric to absorb enough.
Rubbished versions with black pepper in because. allegedly, it can interact with other medications (although it is difficult to find any evidence online).
Praised their liquid in a capsule version.
I still haven't worked out how much (mixed with fat) you have to consume a day to have a noticeable effect.
