it to my green tea daily for about 2 mos., I haven't noticed any difference in pain yet, maybe I should add more.
I believe they are both (iron) chelators and anti-inflammatories. Thanks for your help
I've read that whole turmeric is about 3 to 4% curcumin by weight. I take 1 tablespoon/day. This weighs 9.3 g. Thus, there's about 280 to 372 mg curcumin present. Since curcumin is lipid soluble and not water soluble, I mix it with olive oil and then add some plain yogurt. My theory is that this will help with absorption.
Since your taking 0.25 tsp of whole turmeric, then I would estimate the weight to be around 775 mg and 4% of that is 31 mg which is nowhere close to your 2000 mg number.
The best forms of curcumin for absorption are the BCM-95 curcumins and the phytosome curcumins. You can read about these different forms on the following thread.natural-approach-f27/topic18585.html
Some folks take curcumin with piperine which is an extract of black pepper. This increases the absorption of curcumin (as well as many other compounds). However, piperine inhibits many of the cytochrome (CYP) enzymes and can interfere with detox of foreign substances as well as drug metabolism.natural-approach-f27/topic18613.html#p181912
However, keep in mind that curcumin isn't the only good thing in turmeric. There is also a class of antioxidants known as turmerones. If memory serves me correctly, these are also present in whole turmeric at around 3% by weight.
Here are some papers on turmerones...

Oh, to answer your question.
If not, how much would I need to use to equal 2000 mg?
Assuming all things being equal such as absorption (which is likely incorrect), then...
2000 mg ÷
1000 mg/g ÷
9.3 g/TB = 5.4 TB
