Fundamental Fitness Supplements – L-Arginine

The final supplement I consider to be foundational to any body shaping goal is another amino acid. L-arginine is the only supplement on the list I suggest you use before exercising. Part on the body's nitric oxide cycle, L-arginine is considered a good vasodilator. Nitric Oxide allows the blood vessels to relax and let more blood flow through them.

Why is that so important?

Allowing more blood flow means several positive things during a workout. Your muscles are being used, creating a need for more energy, and blood delivers that energy. Better blood flow also means the waste your muscles are producing will be rapidly removed. Combined, it means a longer harder workout. Relaxed blood vessels means more space for the blood, therefore lower blood pressure. The idea of a workout is to stress specific muscle groups, not the heart.

If you would like to include L-arginine into your supplement plan, I suggest you try to take 3 grams about 30 minutes before you start to exercise. I like the form known as arginine alpha-ketoglutarate, AAKG. In this form, L-arginine is attached to a glutamine precursor which may spare more muscle.
