L-carnitine is a nutrient that promotes energy production in cells by transporting fatty acids into the mitochondrion, an intracellular structure that generates metabolic energy in the form of ATP. In this role, L-carnitine helps the body efficiently metabolize fat. Fumarate is a naturally occurring compound in the body. Fumarate serves as an intermediate in the Krebs cycle, a key energy-producing process that takes place in the mitochondrion.

The L-Carnitine Fumarate in this product is derived from a base of pharmaceutical grade L-Carnitine manufactured by a patented, FDA-approved process. It is GMO-free, pesticide-free, and BSE free.

Seems to give me a turbo boost when I play sports

Posted by 4667848491517456360 on Sep 20, 2016

I am 44 and will take 2 pills about 2-3hrs before I go for my badminton game. I have more energy, sweat a lot more, stamina sustain longer. It is like getting a turbo boost. No noticeable side effect so far. If I just take this pill without going for any sports, I don't feel any difference.
