## Description

L-carnitine is an amino acid naturally produced in the body. It’s a star player in moving fatty acids into the mitochondria, tiny cellular structures that power every cell in your body. Unfortunately, as we age, energy levels decline because mitochondria aren’t functioning as they used to. Healthy carnitine levels help support mitochondrial performance. L-Carnitine encourages cellular health by supporting energy levels, promoting metabolism health, and encouraging healthy nitric oxide concentrations. Carnitine is even good for your brain!
