This video reviews the effectiveness of five popular testosterone-boosting supplements, comparing their muscle-building and fat-loss potential to creatine (ranked as a 10) and the fat-loss drug, trozepatide (ranked as a 10). The presenter aims to determine whether these supplements live up to the hype.
D-Aspartic Acid: Shows minimal short-term testosterone increase but the body quickly adapts, negating the effect. The evidence is weak, and it's considered largely ineffective for muscle growth in humans.
Fenugreek: May slightly increase free testosterone by reducing sex hormone-binding globulin. Studies are small and often industry-funded; the overall evidence is weak, showing only small increases in muscle mass in novice lifters.
Tribulus Terrestris: Poor oral bioavailability limits effectiveness; human trials show minimal impact. It may slightly increase testosterone in older men with ED, but this effect is insignificant for most people.
Ashwagandha: Primarily works by lowering cortisol, not directly boosting testosterone. Evidence is stronger than other supplements mentioned, showing moderate effectiveness in reducing cortisol. However, its effect on muscle growth is limited.
Tongkat Ali: May increase luteinizing hormone and free testosterone. However, high-quality human trials are limited, with variable concentrations in products. There are rare but real reports of liver toxicity.
The overall conclusion is that most natural testosterone boosters are largely ineffective for muscle growth in healthy individuals. Creatine and proper lifestyle choices (sleep, diet, stress management) are significantly more effective.
