Combining L-Carnitine With Your Coffee Can Significantly Improve Cardio Performance, Says Research

It’s already well known that a shot of espresso will give your performance a jolt. Caffeine not only counteracts the metabolism- slowing effects of adenosine – an organic compound that naturally builds up in your body to create feelings of tiredness – but it also makes your cells more sensitive to hormones such as adrenalin. As a result, your muscles are able to work harder for longer.
