Brenda Reed3 said:Without L-carnitine, you can't tap into fat stores for energy, so you absolutely have to supplement it, especially during intense workouts.
I think Ms. Vrbanc phrased this poorly. If her logic actually held water, it would imply that getting lean is impossible without L-carnitine.
Let's cut to the chase: carnitine is a total waste of money. Someone who stays consistent with their training and maintains a clean diet won't lose any more body fat by taking carnitine than someone following the exact same diet and workout plan without it. Research backs this up. When people start a diet, grab some carnitine, finally get their training and nutrition on track, and then lose weight, that isn't because of the carnitine. It's the discipline.
Someone mentioned above that carnitine gave them enough energy to swim across an ocean. That is a textbook example of the placebo effect. A single amino acid simply cannot produce that kind of impact. Look, if carnitine were actually that powerful, pro athletes would be loading up on it constantly, and they aren't.
