Eurycoma longifolia root extract (Physta®) could increase the serum total testosterone, reduce fatigue and improve the quality of life in ageing men

This randomized, double-blind, placebo-controlled study aimed to evaluate the safety and efficacy of Physta® on the testosterone levels and quality of life in ageing male subjects (n = 105). Participants received either Physta® 100 mg, 200 mg or placebo daily for 12 weeks. Results showed that a significant increase in the total testosterone levels at week 12 (p < 0.05) in the Physta® 100 mg group and from weeks 4 (p < 0.05) in the 200 mg group compared to placebo. Changes in Ageing Male Symptoms score and Fatigue Severity Scale score were significantly reduced (p < 0.001) regarding the total scores within- and between-group in both Physta® groups. DHEA levels significantly increased (p < 0.05) within-group in both Physta® groups from week 2 onwards. Cortisol levels significantly (p < 0.01) decreased in the Physta® 200 mg group, while muscle strength significantly (p < 0.001) increased in both Physta® groups at week 12 compared to baseline. No safety related clinically relevant changes were observed. Authors concluded that supplementation of Physta® at 200 mg was able to increase the serum total testosterone, reduce fatigue and improve the quality of life in ageing men.
