A four-month trial tested turmeric extract alongside standard treatment in 160 people with knee osteoarthritis and measured antioxidant and oxidative-stress markers.

WHAT THIS MEANS FOR ROB’S CHOICE

Antioxidant activity is an ingredient research topic, not proof of a health outcome from Longevity. Its final curcumin amount cannot establish the same biological exposure, and the finished product’s effects remain untested.

The doses above describe research, not personal dosing instructions. Ingredient studies do not diagnose symptoms or establish medical suitability. Discuss medicines, existing conditions and treatment decisions with an appropriate healthcare professional.
