What is citrulline - the amino acid from watermelon

Citrulline is a non-proteinogenic amino acid that takes its name from the watermelon(Citrullus lanatus). It was first discovered there. Unlike many other amino acids, this substance is not a direct building block of proteins. Instead, it plays a central role in the body's urea cycle, where nitrogenous degradation products are converted into urea and excreted.

The special property of the amino acid is that it is converted into L-arginine in the body. Arginine, in turn, is the starting material for the body's own production of nitric oxide (NO). This process is scientifically well documented and one of the main reasons why athletes value this dietary supplement.

Interesting fact: studies show that oral intake of the active ingredient can raise the arginine level in the blood more effectively than taking arginine directly. This is due to better bioavailability: the body can absorb and utilize the substance more efficiently.

L-citrulline vs. citrulline malate - what's the difference?

You will come across two variants when buying: pure L-citrulline and malate. Both contain the same amino acid, but differ in one important respect.

Pure L-citrulline - What's behind it?

The pure form contains only the amino acid without any additives. It forms the basis for all products in this category. In practice, however, the malate variant has established itself as the preferred form in the sports sector, as the active ingredient is combined with malic acid (malate). In our range you will therefore only find malate powder in a 2:1 ratio, the variant most frequently used by athletes.

Citrulline malate - the popular combination with malic acid

The malate compound, also known internationally as citrulline malate or L-citrulline malate, combines the amino acid with malic acid. The usual 2:1 ratio means that there is one part malate for every two parts of the active ingredient. Malic acid is a natural component of the citrate cycle, the central energy metabolism pathway in our cells.

What is behind this compound? A combination that provides both components and is the most commonly used form in the sports sector. Most studies in the training context have been carried out with precisely this formulation.

Which variant is the better choice? For use as a pre-workout booster, the malate combination is the clear recommendation. The combination of amino acid and malic acid is by far the most popular form in sports.

Citrulline effect - How does it work in the body?

The effect is closely linked to nitric oxide metabolism. The active ingredient is converted in the body to L-arginine, which in turn is used to form nitric oxide (NO), a messenger substance involved in the regulation of blood vessel width. Athletes use the amino acid because they appreciate the so-called "pump effect" during training, which is associated with increased blood flow to the muscles and a better supply of oxygen and nutrients.

Citrulline and arginine - why the combination is appreciated

Arginine and the amino acid are often used together. Studies have shown that the combined intake of both substances can raise the arginine level in the blood more effectively than taking them individually. A ratio of 1:1 is frequently discussed in the specialist literature. Whether the active ingredient is taken alone or in combination, many athletes deliberately opt for an arginine-citrulline combination.

Citrulline in sport - from strength training to endurance

The amino acid is one of the most popular in sport, and not without reason. Whether strength training, endurance or functional training: from strength athletes to endurance athletes to recreational athletes, many rely on this ingredient as part of their pre-workout routine.

Citrulline as a pre-workout supplement

The amino acid is one of the most frequently dosed ingredients in pre-workout boosters. Many athletes appreciate the so-called pump effect, the plump, full feeling in the trained muscles. Whether as a stand-alone supplement or as part of a training booster, it is hard to imagine modern supplement stacks without this active ingredient.

Citrulline malate for endurance athletes

The malate variant is also used in endurance sports. Studies have investigated whether the amino acid can influence oxygen utilization and the time to fatigue. Athletes report that they use the supplement to support their regeneration after intensive exertion.

Effect on men and women

The L-citrulline effect in men is often sought after, particularly in the context of training and pumping. However, the active ingredient is also relevant for women: The amino acid is used regardless of gender and is just as interesting for female athletes as it is for male athletes. The dosage recommendations generally do not differ according to gender.

Dosage and intake - how to take it correctly

The correct dosage depends on the dosage form and your goal. Here you will find an overview of the current recommendations for the active ingredient.

How much citrulline per day?

In most studies, dosages between 6 and 8 grams per day were used. For use as a pre-workout, a dose of 6 to 8 grams of the malate powder is recommended, which corresponds to around 4 to 5 grams of pure amino acid plus malate content.

When to take citrulline?

For use as a pre-workout, the supplement is taken around 30 minutes before training. According to studies, the highest arginine level is reached around 1-2 hours after ingestion. On non-training days, it can be taken in the morning on an empty stomach or with a meal.

Citrulline malate 2:1 powder - flexible dosing

The powder offers the advantage of flexible dosing: you can adjust the amount exactly to your training. Simply weigh out the desired portion, dissolve in water and drink before training. It has a slightly sour taste, which many people find pleasant. The powder form also means that the active ingredient can be easily combined with other supplements in your stack.
