You may know what nitric oxide is yet if you want to enhance your pump then you should be seeing it on labels more often.
Using a variety of ingredients to increase nitric oxide production, you can increase blood flow to working muscles. Without those ingredients in the right doses, there may not be a worthwhile pump at all.
There are so many pump supplements and pre-workouts available, you may struggle to find the right one that works for you. Some manufacturers want to boast that their formula can achieve the best results. However, you could be consuming the wrong formula and actually doing yourself harm.
There is a range of pump supplements available that will be right for you. Knowing which ingredients work best and what has worked before can help you make the right choice. Whether that is the right flavor, value, ingredient combination, or simply comes from a brand that you trust.
Best Overall Pump Supplement
As the original company to introduce the nitric oxide booster, MRI Performance should know what they are talking about.
They have also had the most time to refine their formula and this one is designed to increase your body’s production of nitric oxide by a huge 230%. If that is not enough for a bigger pump, 4g of citrulline should also help.
As a patented version of arginine, nitrosigine is also specially designed to increase vascularity, as well as your energy and blood flow. We really enjoyed the glycerol powder in our experience of this product to hyper-hydrate your muscles.
- Increased Nitric Oxide Production – The formula can increase your nitric oxide production by 230%

There are simply so many pump supplements out there that you can be spoilt for choice. Your first decision should be based on any intolerances you may suffer from, specifically caffeine.
Thankfully, manufacturers have recognized this issue and toned down their doses. Some supplements can come with ingredients that work as caffeine alternatives so you can use the supplements on their own or with other stimulant-based supplements.
There are other factors to look into too. Many supplements will fully disclose their ingredient list and those with fewer ingredients usually have more science behind them.
Around 15-20 is a good number to consider. The label may also mention whether the pump supplement is third-party tested which acts as a guarantee that no banned substances are included.
If the pump supplement was manufactured in a cGMP-approved facility is another great sign that it meets FDA standards.
A lot of the dosing in pump supplements pays attention to its overall effectiveness. Certainly, the caffeine dose should be of high importance if you have several cups of coffee during the day and want to cut down.
The label should be clear and note the clinically suggested doses of each ingredient. You may be aware of your body’s response to certain ingredients, so it would be a good idea to check how high their doses are.
There are simply so many pump supplements out there that you may have been warned about certain ones yet not necessarily know what to look for.
Third-party testing is one such factor that really makes a difference in your conscience. The more renowned supplement manufacturers will go that extra yard to ensure that their products are tested in an outside laboratory.
This shows the confidence that the manufacturer has that its supplements meet recognized standards.
The tests also show that the supplements are free of any contaminants and banned substances.
You can rely on the objective assessment of these laboratory tests, especially if you are an athlete who regularly faces drug testing.
The tests are also based on the label provided by the manufacturer so you can be assured that the label has been thoroughly checked. However, third-party testing is hard to find for pump supplements so you would be advised to research the manufacturer.
Many supplements boast about how delicious they are yet these are not strictly designed to be tasty. Some supplements are even unflavored, such is the insistence that they remain free of artificial flavors, preservatives, and colors.
You may find a pump supplement that has upwards of six different flavors and it may be easy to pick the one you know you will like.
These flavors can get wacky, from sour gummies to blue raspberry. As long as you can stomach it without feeling the jitters, that is usually a good sign.
While flavor can be important, so is how mixable the pump supplement is. There are reports that some powders struggle to fully dissolve so you may have to swallow lumps and suffer a grainy texture.
You should be able to use regular tap water in a bottle to then give it a quick shake. The color may also seem luminous which is to be expected.
Frequently Asked Questions
Which Ingredients Should I Look Out For In A Pump Supplement?
There are three main ingredients that you should look out for in a pump supplement. These include l-citrulline, l-arginine, and betaine.
When combined, these ingredients have been known to increase nitric oxide production. That one process is crucial to increase blood flow to the muscles you are working on and dilate blood vessels.
Those ingredients will also be in specific doses which do come recommended. For l-citrulline, expect six to eight grams, for l-arginine around three to six grams, and just two and a half grams for betaine.
In your workout, these ingredients should boost your performance. Over time, you should see them work wonders on your pump.
How Do I Increase My Pump?
Aside from ensuring that your pump supplement includes those three ingredients mentioned above in the recommended doses, there are further steps you can take.
Maximizing your muscle pump typically comes from high volumes of weight lifting. That means more reps of moderate loads instead of purely increasing the load.
Science has proven that increased muscle contraction gives your body more incentive to increase the blood flow to those specific muscles.
There are further tips you can use to get more out of your weight lifting, thus increasing your pump.
Ensure you are fully hydrated both before and during your session which is really important for water-based pumps.
Another way to increase your fluid maintenance is to eat some carbs before your workout. The carbohydrates will actively hold the water in your body which should help you achieve a better pump.
