The Claim
Some men use L-Carnitine supplements believing it will naturally boost testosterone levels and improve muscle mass and strength.
Origin
This misconception may arise from the association of L-Carnitine with energy metabolism and muscle performance, often conflated with testosterone's roles.
What Science Says
Research, including controlled trials, does not support the idea that L-Carnitine supplementation significantly alters testosterone levels. Studies primarily focus on L-Carnitine's effects on muscle recovery and performance, with little evidence showing changes in hormone levels.
Verdict
False
