L-citrulline dosage for pump: let’s get the blood flowing!

Taking the right L-citrulline dosage for pump can help athletes increase nitric oxide production, reduce muscle soreness, increase ATP production, and potentially achieve synergistic effects when taken with other supplements. We discuss how much L-citrulline per day to take as well as provide some product recommendations.

What Benefits Can Citrulline Give to Athletes?

Citrulline is an amino acid that is commonly used as a dietary supplement, particularly in the form of L-citrulline or citrulline malate. Athletes often use citrulline for its potential benefits in enhancing exercise performance and recovery. Here are some of the potential benefits for athletes:

✅ Increased Nitric Oxide Production

In the body, citrulline is converted into arginine, which helps to create nitric oxide. Nitric oxide helps dilate blood vessels, improving blood flow and increasing nutrient and oxygen delivery to muscles during exercise. This could help improve exercise performance and endurance.

✅ Reduced Muscle Soreness

Citrulline may help reduce muscle soreness after intense exercise. Studies suggest that citrulline supplementation can alleviate muscle soreness and improve recovery by aiding in the removal of waste products, such as ammonia, from muscles.

✅ Increased ATP Production

Citrulline malate may enhance the production of adenosine triphosphate (ATP), the primary energy currency of cells. This can potentially lead to improved energy levels during exercise and better overall performance.

✅ Combination with Other Supplements

Citrulline is often included in pre-workout supplements alongside other ingredients like beta-alanine, creatine, and caffeine. The synergistic effects of these compounds may provide a more comprehensive approach to enhancing exercise performance.

How Much L-Citrulline to Take for Pump?

The optimal dosage of L-citrulline for achieving a “pump” during exercise can vary among individuals, and it depends on factors such as body weight, individual response, and the specific form of citrulline used (L-citrulline or citrulline malate). Additionally, the timing of supplementation in relation to exercise may influence its effectiveness.

However, a common dosage range for L-citrulline supplementation is typically between 6 to 8 grams taken about 60–90 minutes before exercise. This would be an appropriate range of L-citrulline dosage for bodybuilding. Some individuals may find benefit with doses as low as 3 grams, while others may go as high as 10 grams.

For citrulline malate, the recommended dose to see an effect would be between 10 to 12 grams. It’s advisable to start with a lower dose and gradually increase it while monitoring your body’s response.

It’s worth noting that while citrulline supplementation may contribute to vasodilation and a perceived “pump” by increasing nitric oxide production, individual responses can vary. The overall effectiveness may be influenced by factors such as diet, training intensity, and overall health.

How to Take Citrulline for Best Pump?

To potentially maximize the “pump” effect with citrulline supplementation, it’s essential to consider factors such as dosage (as described above), timing, and synergistic supplements. 

• Timing

Take citrulline about 60–90 minutes before your workout. This timing allows for the amino acid to be absorbed and its effects to be felt during your exercise session. Pre-workout supplementation is common because it aligns with the goal of increasing blood flow and vasodilation during exercise.

• Consistency

Consistency is key. For the best results, incorporate citrulline into your routine regularly rather than using it sporadically. This can help maintain elevated levels of citrulline in the body and potentially enhance its effects over time.

• Combine with Other Supplements

Consider combining citrulline with other supplements known to enhance the “pump” effect. For example, citrulline is often included in pre-workout supplements alongside ingredients like arginine, nitrate-rich foods, beta-alanine, and creatine.

The combination of these compounds may have synergistic effects. In saying this, each nutrient on its own still has a mechanism of action that can help improve performance.

Transparent Labs’ Fermented L-Citrulline

• Serving Size: 1 Scoop
• Servings per Container: 120
• Fermented L-Citruline per Serving: 2000 mg

Transparent Labs’ fermented L-citrulline provides 2000mg of fermented L-citrulline in each 2g scoop. Many studies have reported that L-citrulline supplementation can enhance exercise performance and recovery. Current evidence suggests that in order to enhance exercise performance, supplementing with L-citrulline over the longer term (for example, for more than 7 days) is more effective than single doses at a time.

The minimum effective dose is about 3 g daily of L-citrulline, up to a maximum of 10–15 g daily. The commonly cited range, however, is between 6–8 g daily. Therefore, you would need at least 1.5 scoops of this product to achieve a minimum effective dose. L-citrulline is best taken 60–90 minutes before exercise to enhance performance.

You could mix this supplement with a pre-workout shake consisting of carbohydrates such as juice to achieve this. Sugar from juice is a quick-releasing source of energy that could be used to fuel your training.

Myprotein 100% Citrulline Malate Powder

Citrulline is commonly combined with malate and supplemented as citrulline malate. Malate is a tricarboxylic acid cycle intermediate and has been suggested to enhance energy production, increase the rate of ATP production, and mitigate lactate production.

Therefore, citrulline and malate may have a synergistic effect by increasing skeletal muscle perfusion and enhancing the efficiency of ATP production to improve exercise performance.

Citrulline malate supplement products are often in a 1:1 or 2:1 ratio of citrulline to malate. In order to achieve the ergogenic effects, a citrulline malate dosage of 8–10g daily is recommended, which would translate into approximately 3g of L-citrulline. This product provides citrulline malate in a 2:1 citrulline to malate ratio. In order to achieve at least 6 g of citrulline malate, it is recommended to take 1 tsp mixed with your beverage of choice. 

FAQ

What Is a Safe Amount of Citrulline to Take?

A dose of up to 15g of L-citrulline per day has been tolerated.

Is 10G of L-Citrulline Too Much?

A dose of 10g of L-citrulline daily has been advised as a maximum effective dose, over and above which would not add any additional significant benefits.

Is 2G of Citrulline Enough?

The minimum effective dose of L-citrulline for sports performance is 6–8g daily.

Conclusion

Citrulline has been shown to enhance exercise performance by improving blood flow, reducing fatigue, improving efficiency of energy production, and possibly interacting with other ergogenic ingredients to produce a synergetic response. Generally a dose of 6–8g daily is recommended for optimal exercise performance. Have you supplemented with citrulline? What forms and doses have you tried? Share your experience with us, below!
