Product Overview


Carnitine Benefits:

When searching for the optimal energy production, we all look at the mitochondria of our cells. This is where the magic happens and where energy is created for our bodies to perform at its best. Found in the mitochondria of a cell is an essential nutrient called carnitine. Fat is the most abundant source of energy in the body and provides over 2x more energy per gram than carbs or protein.

Carnitine (found naturally in the cell), helps utilize fat and turn it into a usable energy source.* 95% of the body’s carnitine is located in skeletal and cardiac muscle. A typical diet only supplies approximately 100mg of carnitine a day (vegetarians are likely to have an even lower amount than that).

Why Should You Use MET-Rx L-Carnitine?

MET-Rx L-Carnitine is one of the most versatile supplements available - perfect for all athletes. Carnitine helps the body convert food to energy - providing support for endurance exercise (aerobic) and during recovery from high intensity activities such as weightlifting and sprinting (anaerobic).*

Supplementing with MET-Rx L-Carnitine helps to promote muscle carnitine concentrations at the gym or before athletic competition—right when you need it most! Start using dietary fat to your advantage!


There is a difference between looking big and being strong. True strength takes dedication.

I bought this item hoping it would help my workouts. But at least for me it did not give me energy, or helped me to loose weight.

I use both Liquid Carnitine and this product to get my full dosage of L-Carnitine through the day. Carnitine works best at higher dosage, ideally 4-5 grams per day. It is a natural supplement from an amino acid in the body, that helps metabolize fat for energy. I take one of these with each meal during contest prep.
