@Bansaw Turmeric is the raw ingredient. It is not very bioavailable at all and is loaded with oxalates, which are sharp crystals which impact mitochondria, cause pain and create oxidative stress.
Curcuminoids are the most widely used bioactive ingredients derived from turmeric, sand are known as curcumin. Curcumin is an antioxidant, broad spectrum phase II detoxer, anti-cancer, a COX2 inhibitor and anti-inflammatory.
I use it to decrease brain swelling after my IVIG treatment and it is very helpful.
I used to get IVs if it and found it very helpful. Unfortunately, it is not available in the US currently, so I had to switch to oral and I tested several brands to see which one work the best. Though I use a lot of Thorne Research products, And I know that Thorne Meriva has good science behind it, I tried up to eight grams a day, and it wasn't as effective as the IVs were. I tested Longvida, Liposomal, Thercumin, Sabinsa's formulations, and all the other "high bioavailability" products on the market, and only two had the power I needed:

and

They are expensive, but effective, and noticably better than any of the others.
