curcumin

The bioavailability of curcumin (found in turmeric) is much better when taken along with piperine (found in black pepper).

The description states: Each serving of Qunol Turmeric capsules' formulation contains 2250mg of curcumin with 95% curcuminoids.

And though you can purchase lab-grade curcumin from Sigma Aldrich, it's fairly pricey (approximately 6 $/g).

Turns out, the compound most likely responsible for a lot of turmeric's biologically active properties (basically inflammation reduction/anti-tumor effects) is curcumin[1].

It's interesting to note here that curcumin's coloration is what gives turmeric it's golden sheen.

People taking turmeric medicinally are not actually interested in the curcumin, if they were they would be taking a concentrated extract.

However, to be perfectly honest, it's likely far more efficient to consume curcumin pills.

If you follow the linked references in the Ars Technica, those reference curcumin unambiguously.

Probably over a million people have taken curcumin+piperine supplements that they bought via Amazon.

For example, the combination of turmeric and black pepper in curry is now scientifically proven to increase curcumin's bioavailability by orders of magnitude.

It contains curcumin, a chemical that has quite good evidence for anti-inflammatory properties.

A lot of the spices used for cooking (especially ones sold cheaply and in bulk) may contain less curcumin[absolutely no citation here] because: 1.

That's unlikely, the turmeric used in asian cuisine contains about 3-5% curcumin while what's commonly sold as "turmeric" capsules/supplement often contain > 90%.

From the linked NIH page on drug-induced liver toxicity: “Importantly, means of increasing the bioavailability of curcumin were developed using piperine (black pepper) or lipid nanoparticle delivery methods to increase absorption.

It's called "Turmeric Curcumin with Black Pepper, 2250mg", and the bottle predominantly says "Turmeric" in a large font with the rest in a very small font.

ADI of 0–3 mg/kg of body weight for curcumin..." ) That's concordant with the "up to 3 mg per kilogram of weight" in Ars, which is phrased ambiguously, as if to refer to turmeric.

Curcumin is poorly absorbed but there are several ways to increase the bioavailability[1].
