The Best Nitric Oxide Supplement for Muscle Pump & Vascularity

The Best Nitric Oxide Supplement for Muscle Pump & Vascularity

Posted by MRI Performance on 7th Oct 2022

There's no feeling quite like the pump when you're working out. Your muscles feel engorged, tight, and ready to explode. It's a rush that can push you to keep going even when you're fatigued. But what exactly is the pump, and how can you get the most out of it? The pump occurs when blood and fluids are drawn into muscle fibers during high-volume resistance training. This increased blood flow leads to improved nutrient delivery and waste removal, which can help muscles recover from exercise more quickly. In addition, the pump can also help to delay fatigue during exercise by reducing lactic acid build-up. There are several different supplements that claim to increase the pump, but one of the most effective is No2 (nitric oxide). No2 works by dilating blood vessels, which leads to increased blood flow and an improved pump. If you're looking to maximize your gains in the gym, No2 is worth considering.

When you work out and your muscles start to feel engorged and tight, that's what's known as "the pump." But what's actually happening when your muscles experience a pump?

First, it's important to understand that when muscle tension and contraction occur, nitric oxide increases in the body. This increase in nitric oxide then causes your blood vessels to relax, which allows blood flow to happen more easily. As the blood flow fills the area around the muscle cells, it eventually forces the blood to rush into the muscle itself. And this is what produces the tight, engorged feeling that we call "the pump." It's worth noting that this increase in blood flow isn't just temporary. In fact, studies have shown that regular resistance training can lead to long-term changes in blood vessel function, which can ultimately improve blood flow and circulation throughout the body. So next time you're feeling the pump, remember that it's your body's way of telling you that you're doing something good for your long-term health!


If a muscle pump occurs technically because of increased vascularity and blood flow, then a pump supplement should provide ingredients that boost and aid this process. Vasodilating agents, such as pump pre workouts, work to both counteract vasoconstriction and increase nitric oxide (NO) production.

Nitric Oxide’s main job is to deliver messages between the body’s cells. It also plays a key role in controlling the circulation of blood and regulating activities of the brain, lungs, liver, kidneys, stomach and other organs. But from a muscle-building prospective, NO affects the release of hormones and adrenaline. It’s also said to speed growth and recovery time as well as increase blood flow, thus delivering more nutrients to muscles, helping them grow . - increase in NOS production may enhance oxygen and nutrient delivery to active muscles, thus improving tolerance to physical exercise and recovery mechanisms. Several studies using  NO donors have assessed this hypothesis in a healthy, trained population. -

Nitric Oxide is key to a pump occurring and there are agents that aid in its production. Below is a list of the best pre workout ingredients for pump that effective muscle pump supplements should include.


As arginine is converted into nitric oxide, L-Citrulline is also produced. The aminos work synergistically to increase NO and enhance blood flow.

L-Citrulline increases the level of L-Arginine. This is important because when arginine is taken directly, it is broken down in the liver leaving little to be absorbed by the gastrointestinal tract. Citrulline is able to bypass the liver and convert to arginine in the gastrointestinal tract so your body can utilize more of the arginine. Remember, more arginine can help create more nitric oxide.


Here are seven tips to help you maximize a supplement to achieve a great pump.

  1. Apply the time under tension (TUN) method to your weight training
  2. Limit the range of motion when contracting the targeted muscle to optimize the use and contraction of the muscle
  3. Increase your rep count
  4. Decrease your rest time in between sets
  5. Utilize drop-sets and pyramid training
  6. Practice the mind-muscle connection by focusing on every rep, each set
  7. Slow down your tempo to control the movement and squeeze the muscle
