                                L-carnitine is a natural amino acid derivative produced in the body that transports fatty acids to the mitochondria for energy. However, unlike stimulants, its effects build up over time, meaning you won't feel a sudden boost. The timeline for when you start to see benefits from L-carnitine can range from a few weeks to several months, depending on your goals and consistency.
