Here is an interesting article about the benefits of acetyl-l-carnitine. This article focuses on how this form of carnitine can benefit brain function.
Jigsaw Health just started shipping a new Carnitine Blend product that combines the two most common forms of carnitine in one supplement. Many doctors recommend taking both forms. I like things convenient though and hate taking two supplements when I could take one. That is why we put them together.
L-Carnitine helps with cardiovascular functions and energy while the n-acetyl form crosses the blood brain barrier and helps the brain function at it's peak. This article above talks about studies that show it can help with cognitive decline as well. Jigsaw offers a convenient way to get the benefit of both!
