What the Evidence Says

AI-generated · Qwen 3.6 · methodology

L-carnitine is used to support fatty acid transport and energy metabolism, though research on its efficacy for weight loss is mixed. Pantothenic acid is a critical cofactor for energy production and cellular metabolism. Evidence for these ingredients is generally moderate, and the profile maintains a high safety score.

Formulation Notes

MET-Rx L-Carnitine 1500 is one of the most versatile supplements available - perfect for athletes and anyone trying to get into better shape.

Carnitine helps the body convert food to energy - providing support for endurance exercise (aerobic) and during recovery from high intensity activities such as sprinting (anaerobic).

Our formula is further enhanced with a high potency dosage of pantothenic acid (vitamin B5). Once pantothenic acid is converted into coenzyme A in the body, it works directly with carnitine to convert food to energy - providing synergistic support.

Exercise recovery Helps the body convert food to energy Promotes recovery from high intensity exercise

Vegetarian friendly

Additional Information

Supplementing with our fast-acting liquid formula helps to maximize muscle carnitine concentrations before athletic competition.

Store unopened container at room temperature and avoid excessive heat.
