Also known as PLCAR & GPLC (due to the addition of Glycine in the compound), Propionyl L-Carnitine is an amino acid that primarily promotes the growth and energy of muscles. This makes it a functional performance enhancer but a lackluster cognitive booster.



Propionyl L-Carnitine has a high bioavailability (with a rate of nearly 80%) and acts as a capable cardio antioxidant, ensuring that it has a role to play in the removal of cellular waste and the protection of organs from harmful disease. The glycine in the compound metabolizes into creatine once it is processed, a common supplement used for muscle building. Due to its cardiovascular and metabolic functions it is primarily used as a bodybuilding supplement to enhance its user’s endurance and weight loss goals. Propionyl L-Carnitine’s energy production comes from its ability to deliver fatty acids into the mitochondria. Its properties as an antioxidant helps to efficiently remove waste and ensure that the body is protected from illnesses such as heart disease, type II diabetes, and kidney disease, all to keep it running strong to prioritize muscular growth. It has been shown to reduce the buildup of lactic acid in the muscles, which occurs when a lack of oxygen is present to help break down glucose and glycogen. A smaller production of lactic acid buildup in the muscles results in an increased power potential of up to 15%.

Side Effects & Dosages

Nausea and diarrhea are common side effects, but more rare instances of sleeplessness, an increase in appetite, horrid body odor, and rashes are all possible. Despite this, Propionyl L-Carnitine has been rated as generally safe when taken appropriately. However, it is important to seek the counsel of a qualified medical professional when discussing personal information that could affect consumption. Dosages can vary depending on the age, weight, and reasons for use, but typical reports show that 1-4.5 grams daily is enough to incite the compound’s effects.
