Jose Sanchez where and how do I get it ,???

Tattva's Herbs Dorinda Busath..no the extract by definition is already "preserved" ...these companies use acetone and sometimes hexane to move the curcumim level from 70% or 75% to 95%..

It is completely unnecessary but they do this instead of using co2 extracts which include the lipids or fat soluble components called turmerones.
Co2 provides a full spectrum product.

95% extracts provide very little bioavailability even with pepper. Oh yes they also provide the carcinogens from these solvents.

Bottom line is that it is driven by marketing and profits. Not your health. And yes these are the powdered extracts in capsules you see in all products that say 95% extract. So it's a huge problem.

And the FDA neither tests for these solvents or cares. Why? Because they are used extensively in the pharmaceutical industry.
