Standardized Morinda citrifolia L. and Morinda elliptica L. leaf extracts alleviated fatigue by improving glycogen storage and lipid/carbohydrate metabolism.
Osman WNW, Mohamed S.

Noni leaf extract significantly increased physical endurance (swim time) of mice via improving lipid catabolism, carbohydrate metabolism, electron transport, antioxidant responses, energy production, and tissue glycogen stores. The extract also reduced blood lactate and blood urea nitrogen levels. It also improved antioxidant responses, electron transport, and energy production biomarkers. Noni leaf extract was better than Morinda elliptica leaf extract and green tea in reducing fatigue. (original abstract available at
