The Claim

Oral administration of 2 g curcumin in healthy humans results in undetectable or negligible serum concentrations due to rapid metabolism and limited intestinal absorption.

How it works
1 study reviewed
In plain English

When healthy people take 2 grams of curcumin by mouth, almost none of it enters the bloodstream because it is broken down quickly and not absorbed well in the gut.

See the scientific wording

Oral curcumin at a dose of 2 g produces undetectable or negligible serum concentrations in healthy humans when administered alone, indicating extremely poor oral bioavailability due to rapid metabolism and limited absorption.

Why this might work

When curcumin is swallowed, it gets broken down too quickly by enzymes in the gut and liver before it can enter the bloodstream, and very little of it gets absorbed at all, so almost none shows up in the blood.

  1. Study: Influence of Piperine on the Pharmacokinetics of Curcumin in Animals and Human Volunteers

    When people take 2 grams of curcumin by itself, almost none of it shows up in their blood because the body breaks it down too fast — but when they take it with black pepper, it suddenly shows up in measurable amounts, proving it was blocked before.
