The Claim

In rats, co-administration of 20 mg/kg piperine with 2 g/kg curcumin increases curcumin bioavailability by 154% compared to curcumin alone, associated with a significant reduction in systemic clearance and elimination half-life, indicating that piperine inhibits metabolic breakdown and prolongs curcumin’s presence in circulation.

How it works
1 study reviewed
In plain English

In rats, combining 20 mg/kg piperine with 2 g/kg curcumin results in 154% higher curcumin levels in the blood than curcumin alone, due to reduced clearance and shorter elimination half-life.

Why this might work

When piperine and curcumin are taken together, piperine blocks enzymes in the liver and gut that normally break down curcumin into inactive forms. This allows more curcumin to stay intact and enter the bloodstream, where it remains for a longer time instead of being quickly removed.

    Adding piperine (from black pepper) to curcumin (from turmeric) helps the body keep more curcumin in the blood for longer by slowing down how fast the liver and gut break it down — just like the claim says.
