Introduction
Sprinting is a physically demanding sport that requires a combination of speed, power, and endurance. As one of the most explosive athletic disciplines, sprinters need to focus not only on their training but also on proper nutrition and supplementation to optimize their performance and recovery.
One such supplement that has gained significant attention in recent years is Citrulline Malate.
Citrulline Malate, by increasing Nitric Oxide levels in the body, increases blood flow which increases nutrient delivery, reduces muscle fatigue, increases endurance and improves recovery.
In this blog post, we will explore Citrulline Malate in detail, discussing its benefits for sprinters, recommended dosage and timing, and how to incorporate it into your training regimen. By understanding the science behind this powerful supplement, you can make informed decisions to improve your sprinting performance and overall athletic prowess.
What is Citrulline Malate?
Definition and chemical structure
Citrulline Malate is a compound made up of two components: L-citrulline, a non-essential amino acid, and malate, an organic salt derived from malic acid.
L-citrulline is naturally produced in the body and can also be found in certain foods, while malate is a key component in the tricarboxylic acid (TCA) cycle, which plays an essential role in energy production.
Sources of Citrulline Malate in nature
Citrulline Malate can be found in nature, primarily in watermelon (hence this article’s image), from which its name is derived. Other food sources include melons, cucumbers, and pumpkins.
However, the concentrations of Citrulline Malate in these foods are relatively low, making supplementation a more practical option for athletes seeking to optimize their intake.
The process of conversion from Citrulline Malate to L-arginine and Nitric Oxide
In the body, Citrulline Malate is converted into L-arginine, another amino acid. L-arginine is then used to produce Nitric Oxide (NO), a molecule that acts as a potent vasodilator.
This means that it helps widen blood vessels, allowing for increased blood flow and improved nutrient and oxygen delivery to muscles.
This process plays a crucial role in the benefits that Citrulline Malate offers to sprinters, as we will discuss in the following section.
Benefits of Citrulline Malate for Sprinters
Improved blood flow and nutrient delivery
1. Nitric Oxide (NO), produced as a result of Citrulline Malate supplementation, is responsible for vasodilation, or the widening of blood vessels. This process allows for increased blood flow throughout the body, including the muscles used during sprinting.
2. Enhanced blood flow means that more oxygen and essential nutrients can be delivered to working muscles during exercise, which is vital for optimal performance, especially in high-intensity sports like sprinting.
Of course, throughout the length of a single 100m race this might not have much of an effect, but over the course of an intense training session such effects are important.
By increasing the blood flow, citrulline malate can improve various elements of athletic performance
Reduced muscle fatigue and soreness
1. Citrulline Malate has been shown to help buffer lactic acid and ammonia production during intense exercise. These by-products can cause muscle fatigue and soreness, limiting performance during sprints and prolonging recovery time.
2. By reducing the accumulation of lactic acid and ammonia, Citrulline Malate can help sprinters recover more quickly after workouts, allowing them to maintain a higher training volume and intensity. This is especially important for 400m sprinters.
Increased muscular endurance and performance
1. The delayed onset of muscle fatigue associated with Citrulline Malate supplementation enables sprinters to maintain their speed and power output for longer durations, potentially leading to better performance in both training and competition.
2. Studies have shown that Citrulline Malate can enhance power output and speed in athletes, making it an ideal supplement for sprinters looking to improve their performance on the track.
By buffering lactic acid and ammonia production, Citrulline Malate can improve athletes’ endurance.

Strengthened immune system
1. Intense exercise, such as sprinting, can produce oxidative stress, which can weaken the immune system. Citrulline Malate has been shown to reduce oxidative stress, helping to support overall health and well-being.
2. A stronger immune system means fewer missed training sessions due to illness and faster recovery from injuries, allowing sprinters to consistently perform at their best.
Comparing Citrulline Malate to Other Nitric Oxide Supplements
L-Arginine
1. L-arginine is a direct precursor to Nitric Oxide and is often used as a supplement for similar benefits as Citrulline Malate. However, L-arginine has lower bioavailability and is more prone to degradation in the digestive system, which can lead to less effective results compared to Citrulline Malate.
2. Additionally, L-arginine supplementation may cause gastrointestinal distress in some individuals, making Citrulline Malate a more comfortable and easily tolerated option.
Beetroot Extract
1. Beetroot extract is a popular Nitric Oxide supplement due to its high concentration of dietary nitrates, which are converted into Nitric Oxide in the body. While beetroot extract has been shown to improve exercise performance, its effects are generally more pronounced in endurance sports rather than high-intensity, short-duration activities like sprinting.
2. Beetroot extract can also cause a temporary reddening of the skin (flushing) and may alter the color of urine and stool, which some users may find off-putting.
Beetroot extract contains relatively high levels of Nitrates, which when consumed can lead to high levels of NO in the body.
Agmatine Sulfate
1. Agmatine sulfate is another supplement that can enhance Nitric Oxide production. However, research on its effectiveness is relatively limited compared to Citrulline Malate, making it a less established choice for athletes seeking performance benefits.
2. Some users have reported mild side effects with Agmatine sulfate, such as gastrointestinal discomfort and lowered blood pressure, which may make Citrulline Malate a more appealing option for some individuals.
Comparing Benefits and Potential Negatives
1. Citrulline Malate has a more direct and efficient pathway to Nitric Oxide production than L-arginine, making it a more effective supplement for enhancing blood flow, reducing muscle fatigue, and improving overall performance.
2. While Beetroot extract offers benefits for endurance athletes, Citrulline Malate’s effects on buffering lactic acid and ammonia production make it more specifically suited to the needs of sprinters.
3. The limited research on Agmatine sulfate, coupled with potential side effects, makes Citrulline Malate a more established and reliable choice for athletes seeking the benefits of Nitric Oxide supplementation.
Recommended Dosage and Timing
Common dosage guidelines for Citrulline Malate
Common dosage guidelines for Citrulline Malate vary, but most studies and experts suggest a daily intake of 6-8 grams for optimal results.
It is important to note that individual responses to supplementation may differ, so some athletes may require more or less of the supplement to achieve the desired effects. As always, individual differences are relevant.
Best time to take the supplement for optimal results
he best time to take Citrulline Malate is typically 30-60 minutes before a workout or competition. This timing allows the body sufficient time to convert the supplement into L-arginine and subsequently Nitric Oxide, ensuring that its benefits are fully realized during the exercise session.
