Product Overview

Liquid L-Carnitine

Carnitine Benefits:
  • Assists in fat breakdown of food being used for energy*
  • Assists in fat metabolism*
  • Plays a role in fatty acid oxidation to make more ATP available*
  • May help support heart health*
  • Plays an essential role in making fatty acids available for muscle tissue*
  • Promotes muscular energy*
  • Supports exercise recovery*

Supplementing with our fast-acting liquid formula helps to promote muscle carnitine concentrations at the gym or before athletic competition — right when you need it most!*

Met-Rx® Liquid L-Carnitine 1500 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).*

Our formula is further enhanced with a high amount of Pantothenic Acid (Vitamin B5). Once Pantothenic Acid is converted into Coenzyme A in the body, it works directly with Carnitine to support converting food to Energy.*

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 a 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).


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

I love the MET-Rx Liquid L-Carnitine. It is the first time I have taken the liquid form and I have loved the fast acting effects. I take 1 TBSP in the morn. with breakfast and a second with lunch or dinner. I have had a nice energy and feel that my body is working better since taking it for the last 2 months.

I'm not rating the quality of the product. Just the flavor. I can't take it without gagging. It's disgusting. It kinda burns the back of my mouth.

DO NOT buy this. It's the WORST carnitine liquid I have tried. Its syrupy & has sugar alcohol. It can't be taken on an empty stomach or you'll feel nauseous.

Best tasting liquid L-carnitine! Love this stuff... Both flavors. I take 1 tbsp in the morning before cardio, and 1 tbsp in the afternoon before lifting. I combine that with carnitine tablets to reach my daily dosage of 4-5g per day.
