What it is
L-carnitine is a naturally occurring amino acid derivative, which is a compound similar to the building blocks of proteins. It is often sold as L-carnitine or ALCAR, which is a specific version called Acetyl-L-carnitine that can more easily enter the brain.
Why it's used
It is primarily used to support fat metabolism, which is the process the body uses to break down fats to create energy. By helping the body move fatty acids into the cells to be burned, it is used by people looking to improve their energy levels or manage their weight.
How it compares to Fat Burners
While L-carnitine is often found inside fat burner supplements, it works differently than a standard fat burner.

How it's made
To make this supplement, manufacturers typically start with a raw material derived from either chemical synthesis or natural sources. This material is processed into a concentrated powder through a series of purification steps to ensure it is pure. Finally, the powder is either put into capsules or mixed into a liquid syrup for the consumer.
What it typically costs
This supplement is generally mid-range in price. This is because the chemical synthesis required to create a stable, pure powder is more complex than simple vitamin extraction, but the ingredients are common enough that there is plenty of competition among brands.
