8 Health Benefits of L-Citrulline

Key Takeaways

* L-Citrulline is proven to improve muscle endurance and stamina

* Supplementing with L-Citrulline increases blood flow as well as heart health and function

* L-Citrulline is also effective in reducing fatigue and muscle soreness in addition to speeding up muscle recovery


What is L-Citrulline?

L-citrulline is an amino acid that your body converts into both L-arginine and the chemical called nitric oxide. This conversion occurs in the kidneys and the resulting compounds are critical to the health of both your heart and blood vessels.


How Does it work?

Nitric oxide is a compound used by the body to expand the blood vessels which enables the delivery of more oxygen-rich blood to your muscle tissue. This process is referred to as vasodilatation. Both L-arginine and L-citrulline increase nitric oxide levels, however, L-citrulline as a supplement is more effective in doing so because it is far easier for the body to metabolize. L-arginine can also cause nausea, vomiting, and diarrhea when taken in high doses which makes L-citrulline a better choice as a supplement to increase nitric oxide.


The Benefits of L-Citrulline

* Improved Physical Performance

A clinical study has shown that supplementing with L-citrulline prior to workouts provides a substantial increase in muscle endurance. In this case, the number of reps that test subjects where capable of completing increased by 52%. It’s also proven to provide a significant boost in cellular energy production (or ATP) which in turn increases your potential physical output.

* Reduced Soreness and Improved Muscle Recovery

L-Citrulline has been shown to reduce muscle soreness and post-workout fatigue while also boosting creatine phosphate levels which serve as a reserve source of energy for your muscles.

* Improved Erectile Function

With nitric oxide being the key to vasodilation and improved blood flow, it makes sense that the increased nitric oxide levels that L-citrulline provides can give you better, stronger, longer lasting erections. A study determined that not only did supplementing with L-citrulline significantly improve instances of erectile dysfunction but it also increased the satisfaction and frequency of sex for the men in the study.

* Improved Heart Health

The hardening of the arteries, the major pathways through which the heart delivers oxygen-rich blood to the rest of the body, is referred to as arteriosclerosis. This condition can eventually lead to both strokes and heart attacks. Nitric oxide helps the arteries to expand, reducing blood pressure and blockage while maintaining their elasticity. The boost in the nitric oxide that L-citrulline supplementation provides gives the benefit of keeping your heart and arteries healthy.

* Increased Levels of Growth Hormone

L-citrulline increases blood arginine levels. Arginine blocks the release of the hormone that inhibits the growth hormone. A study revealed that cyclists who supplemented with L-citrulline had significantly higher levels of growth hormone after training when compared with a non-supplemented control group.

* Boosted Immunity and Reduced Toxicity

Free radicals, or compounds that have to potential to cause cell or DNA damage in the body, are unavoidable in our body chemistry. The foods you eat and the substances you ingest can also increase your levels of these toxic compounds. Higher amounts of free radicals can contribute to cancer, aging, degenerative diseases, and other conditions. L-citrulline has been shown to not only reduce the number of free radicals that your body produces during exercise but also help prime the immune system for the oxidative burst that occurs during a workout.




L-citrulline combined with malic acid to produce Citrulline malate is superior to supplementation with L-citrulline alone for two key reasons. The first being that malic acid is critical to the creation of cellular energy and has been shown in animal tests to improve endurance. Additionally, Citrulline malate is the form typically administered in most of the studies that have demonstrated the physical enhancement that L-citrulline provides.

Given that L-citrulline has many different benefits, different amounts are necessary to produce each individual desired result. A catch-all dosage, so to speak, would be no less than 3 grams per day to achieve all the positive effects that this amino-acid has to offer.


Potential Side Effects

L-citrulline has not been shown to have adverse side effects from supplementation even at high doses making it not only an extremely effective supplement but also a very safe option. It does, however, have the potential to interact with medications such as nitrates or drugs used to treat erectile dysfunction. You should check with your healthcare provider prior to taking L-Citrulline if you’re taking these kinds of medications.


Natural Sources

L-citrulline can be found naturally in many vegetables of the gourd family such as watermelon, squash, melons, cucumber, and pumpkin. Unfortunately, it’s not present in levels high enough to achieve the desired benefits that L-citrulline has to offer therefore you need a high-quality supplement with an adequate dose of L-citrulline malate like Enzo Nutrition’s Formula Won.


What you can Expect From Formula Won

Time after time the research has clearly shown that L-citrulline can have a huge impact by giving you heightened performance during workouts, faster recovery, a healthier heart and even a boost in the bedroom. The 6g grams of L-citrulline that Formula Won provides is all you need to realize these benefits.

L-citrulline is only one of many synergistic supplements incorporated in the Formula Won blend. This product features 10 total active ingredients that help you by improving circulation, giving you bigger, better pumps, increasing your muscle endurance, reducing your fatigue and speeding muscle recovery.

L-citrulline works even better in conjunction with norvaline, also an ingredient in Formula Won, an amino acid that inhibits the action of arginase (the enzyme that breaks down arginine therefor lowering blood arginine levels). When arginase is inhibited, nitric oxide levels increase due to the continuous production which is possible when adequate L-arginine is present.
