About this item
Product details
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, which in turn help maintain already-healthy blood pressure levels. Carnitine is even good for your brain!

Works for me
[This review was collected as part of a promotion.] I am 68. I have been using L Carnitine for about 5 years. For me, it is the difference of being able to do 2 sets of reps and doing 3 sets of reps. It helps release additional energy for me to use.
