L-Carnitine
Verified Purchase
Large capsules, but not difficult to swallow. Much has already been said about mitochondria. L-carnitine is an amino acid that helps transport fatty acids to the mitochondria of cells, where they are converted into energy. It is used to support weight loss, improve athletic endurance and increase energy. It is also beneficial for the cardiovascular system, can lower cholesterol levels and helps fight chronic fatigue. Since the beginning of use, I have definitely had more energy. That is why I stopped feeling tired and have such conclusions. Tasteless, the packaging is used to be practical.

big pill
Verified Purchase
It's a large tablet; I crush it. It tastes like a sour berry. I take it before workouts; it boosts endurance. It won't help without training. So if you're just taking it while you're lying on the couch, it won't change anything. I've been taking it for two weeks, training three times a week, and watching my food. I'm 39, and my metabolism isn't like my youth's, so I haven't seen much of a result yet.

I really like this supplement. High dosage and good quality. I take it during my most active periods and feel more energetic throughout the day. The tablets are large but easy to take.

This is my first time using this product, and I'm very satisfied. The taste is tasteless, and the quantity is sufficient. I take it before any exercise.

I drink this before going to the gym. Not only do I sweat more, but my body seems to stay warmer for longer.
