Tongkat Ali
Tongkat Ali is a Southeast Asian herb traditionally used as an aphrodisiac and adaptogen. B-grade evidence for erectile function (small effect). C-grade evidence for cortisol reduction. IMPORTANT: Despite heavy marketing as a 'testosterone booster', evidence for testosterone increases in healthy men with normal testosterone is weak and inconsistent. Effects on testosterone appear limited to men with clinically low levels. Most studies have small sample sizes and methodological limitations. May have genuine adaptogenic effects on stress/cortisol.

Citrulline
7 shared conditions · 169 outcomes
L-Citrulline, or simply just citrulline, is a nonessential amino acid. It is efficiently turned into L-arginine in the kidneys after supplementation, which makes it a good choice for increasing nitric oxide synthesis in the body.
L-Carnitine

L-carnitine can relieve leg pain in people with peripheral artery disease (PAD) and treat some aspects of metabolic syndrome. Although it’s often also used for fat loss, its effectiveness for that is questionable.
