Synergy
What is happening. Tribulus and Tongkat Ali are both used to support libido and male sexual function, with complementary traditional and clinical use for that goal.
Mechanism. Tribulus saponins act largely on libido and nitric oxide signaling while Tongkat Ali quassinoids may support free testosterone by reducing sex hormone binding globulin activity, giving complementary effects on sexual function.
Recommendation. Combination is reasonable for libido support. Monitor for overstimulation and discontinue if restlessness or sleep disturbance occurs.
