L-Carnitine and acyteyl-l-carnitine are often confused. Though they fall under the same title ‘carnitine’ and are derived from the same amino acid ‘carnitine,’ they are not the same thing. It’s important to know the difference between l-carnitine and acyteyl-l-carnitine, especially in terms of heart health and supplements. What’s also important to understand is the difference between L-carnitine and L-carnitine tartrate.

L-Carnitine Tartrate

L-carnitine tartrate is the purest form of carnitine available, and a key ingredient in Cardio Juvenate. Studies suggest that l-carnitine tartrate is absorbed in the body faster and more efficiently, more directly affecting the metabolism, muscle growth, and aging. L-carnitine is the highest quality, most potent form of l-carnitine, and the type that you will see the greatest benefits from.


According to The Health Sciences Institute, in the process of delivering fatty acids to the mitochondria, L-carnitine is converted to acetyl-L-carnitine, which enhances brain activity. Whiel L-carnitine tartrate excels at weight loss and energy creation, acyteyl-l-carnitine is important for brain development.

Supplments with L-Carnitine

Cardio Juvenate ingredients include l-arginine and l-carnitine tartrate, not acyteyl-l-carnitine, for many reasons. Since l-arginine improves circulation, increases brain function, and lowers the risk of heart disease, we decided to use l-carnitine tartrate instead of acyteyl-l-carnitine since this amino acid and l-argnine serve similar purposes.

However, by combining the amazing benefits of l-arginine with the improved metabolism, muscle building and weight loss benefits of l-carnitine tartrate, we have a formula that is both good for your heart, but good for your exercise and weight loss regiments as well.
