Nitric Oxide is something every lifter thinks they need, though most of them don’t have a single #@*&ing clue why. The term is repeated ad nauseam on every website you could visit having to do with lifting, but beyond knowing it produces a pump, they know nothing about it. So for the layman, nitric oxide, or NO for the cool kids, is a gas produced naturally by the body that helps increase blood flow. NO supplements increase the amount of nitric oxide in your body, which should lead to huge muscle pumps, better endurance, and faster recovery.

Citrulline is the grandaddy of NO supplements. Of the three amino acids involved in the production of NO, citrulline produces the greatest increase in blood flow, and has been shown in studies to increase work capacity, decrease fatigue and soreness, improve muscle oxygenation, and increase GH release while training. It’s the perfect addition to any preworkout, and due to the increase in blood flow should improve cognition and mood, so literally any time is a good time to take citrulline.

From increasing blood flow to your junk to making you look huge in the gym and improving your trivia score at the bar, Citrulline is the golden god of supplementation that can make every facet of your life better through its use.

Dosage depends on what you’re going to be doing. If it’s to enhance sports performance, take 6-8 grams of citrulline an hour prior to working out. If it’s just to aid in circulation (whether in the lap region or your brain) take a gram of citrulline three times a day.
