Benefits

Joint comfort and function

In a randomized, placebo-controlled trial in overweight adults, the extract improved joint-discomfort and function scores during daily activity and exercise compared with placebo, even in people without diagnosed arthritis.

Antioxidant support

The fruit is dense in polyphenols that neutralize free radicals, which the manufacturer links to its joint and recovery benefits.

Mobility during activity

Participants reported easier movement and less exercise-related joint discomfort, suggesting usefulness for active and overweight individuals.

Mechanism of action

1

Polyphenol antioxidant activity

Chebulinic acid and related tannins scavenge reactive oxygen species and dampen inflammatory signaling that contributes to joint discomfort.

2

Support for joint tissue

By lowering oxidative and inflammatory stress in and around the joint, the extract is proposed to support comfortable movement.
