L-citrulline acts as a precursor of nitric oxide

The use of the amino acid L-citrulline focuses on performance, both in sport and in your intimate life. Discover its relationship with nitric oxide and its vasodilating effect.

What is L-citrulline?

L-citrulline is a non-essential amino acid, which means it is produced by the body, but can also be found in foods such as fruit, especially watermelon, as well as in food supplements.

In recent years, the search for improved sports performance has highlighted that amino acids such as L-citrulline are involved at a metabolic level in processes related to physical performance due to their role as precursors of nitric oxide (NO), a molecule that promotes blood flow (vasodilation) and the transport of oxygen and nutrients to the muscles.

Due to the vasodilating effect of nitric oxide, L-citrulline can also be used by those who experience problems in their intimate relationships, regardless of age.

We explain everything in detail below.

What is citrulline used for?

The citrulline molecule stands out for its relationship with nitric oxide, which is a powerful vasodilator and therefore very interesting in different situations such as:

L-citrulline

L-arginine

Nitric oxide

Vasodilating effect

L-citrulline for pre-workout

L-citrulline is usually consumed as a pre-workout supplement, that is, before training, with the aim of:

On the one hand, increasing blood levels of L-arginine. This occurs thanks to the conversion of L-citrulline into L-arginine, an amino acid precursor of nitric oxide, a molecule that causes a vasodilating effect in blood vessels, leading to greater muscle oxygenation. A key point when the goal is to improve sports performance.

On the other hand, reducing fatigue after training. This is due to the involvement of L-citrulline in a series of metabolic reactions that are key in the production of aerobic energy. When these reactions occur, we “gain time” and delay obtaining energy through the body's anabolic pathways, which can accelerate muscle breakdown (catabolism)¹.

L-citrulline for post-workout

Less well known is the use of L-citrulline powder after training. Consuming it in this way is based on the fact that, as a natural precursor of nitric oxide, a substance that improves blood flow, the nutrients circulating in the bloodstream can be optimally available for post-workout muscle regeneration and recovery processes.

L-citrulline for sexual relationships

The vasodilating effect of nitric oxide is a plus during sexual intercourse, allowing greater blood flow. As mentioned, L-citrulline is a natural metabolic precursor of this substance and, thanks to this vascular effect, it can become an ally in intimate relationships².

How does it work?

When taken, L-citrulline is converted into L-arginine, which in turn becomes a molecule called nitric oxide, causing dilation of blood vessels (vasodilation) by relaxing the contracted cells of smooth muscle.

This allows oxygen and other nutrients in the blood to reach the muscles and other parts of the body more effectively.

Why buy L-citrulline powder from Abs^®?

Add to basket

• 100% pure L-citrulline of natural origin

  Our L-citrulline is an amino acid obtained by fermentation, completely natural, with no additives, preservatives or flavourings.

  Its powder format makes it very versatile, allowing it to be mixed into smoothies, recipes or even dissolved in water, as its natural flavour with a slight citrus note is very pleasant.

• Combine it to optimise your training

  L-citrulline is an amino acid that can be perfectly combined with other products commonly used to improve sports performance, such as creatine or whey protein.

• High bioavailability

  At intestinal level it has greater bioavailability than L-arginine, meaning that L-citrulline is better absorbed by the body. In addition, at digestive level and compared to L-arginine, it usually causes fewer stomach discomforts, which can hinder or ruin a good training session.

  Therefore, if the goal is to increase L-arginine levels as a precursor of nitric oxide, consuming L-citrulline powder is always the better option.

• L-citrulline suitable for vegans

  As it is obtained by fermentation, our L-citrulline is ideal if you follow a vegan or vegetarian diet, or if you simply wish to reduce your intake of animal-derived products or avoid synthetic products.

  The fermentation process by which L-citrulline is obtained is completely safe and offers maximum quality.

• Safe L-citrulline

  This is a food supplement based solely on L-citrulline powder, GMO-free (genetically modified organisms), free from heavy metals and manufactured in specialised laboratories under European regulations to offer the highest quality and confidence.

  In addition, we guarantee that our L-citrulline complies with sports regulations and has not been contaminated with any prohibited (doping) substance according to the WADA (World Anti-Doping Agency) list.

What benefits does citrulline offer?

Involved in nitric oxide production (vasodilation)

L-citrulline acts as a precursor of L-arginine, which ultimately forms nitric oxide. This acts as a vasodilator by relaxing smooth muscle and promoting blood flow and the delivery of oxygen and nutrients to the muscles.

The action of nitric oxide is beneficial during training, both in endurance sports, where aerobic energy pathways are activated, and in strength and high-intensity activities.

Well absorbed by the body

Intestinal absorption of L-citrulline is very high, making its intake more efficient than that of other amino acids such as L-arginine, which interacts with other nutrients that may affect its availability.

This is noticeable at intestinal level, avoiding digestive issues that could interfere with training sessions.

Involved in ammonia elimination

At a metabolic level, citrulline participates in the urea cycle. This metabolic process aims to convert excess ammonia in the body into urea, which is then eliminated.

In sport, we often encounter situations where the diet exceeds the recommended protein intake (high-protein diets), consequently increasing blood ammonia levels, which can become toxic if not eliminated. This mechanism helps balance excess ammonia and remove it through urine.

Better to take L-citrulline than arginine

Generally, L-citrulline supplements are taken instead of arginine due to their better tolerance and intestinal bioavailability. In addition, L-arginine is not recommended in cases of herpes allergy or infection, as it may worsen the condition, nor when taking medication for blood pressure.

L-citrulline powder can be combined with other supplements

L-citrulline is a very interesting amino acid in a training routine, as it combines very well with other common products such as creatine or protein.

When combined, each provides specific benefits that help you maximise your effort and training time. In addition, its powder format allows you to mix and create your own pre-workout and post-workout drinks.

How to take L-citrulline powder?

The recommended dose of L-citrulline is 3 grams, exactly the capacity of the level measuring spoon included in the container, dissolved in 250 ml of water.

* You can also mix it with the drink of your choice, even a hot one, without affecting its properties, but water is recommended as it hydrates and has no side effects on performance.

For preparation, we recommend shaking and letting it rest for a few minutes before consumption.

Contraindications

L-citrulline has no contraindications provided it is used as indicated on the label and its precautions for use are respected.

When to take L-citrulline

Depending on your goal, the best time to take L-citrulline may vary. Here we indicate when it is preferable to take it according to your needs:

For training

If you take it for training, we recommend consuming it between 30 and 60 minutes before or after (depending on your goal) physical activity.

When not training

If you are not exercising, you can take it at any time of day as it does not negatively affect sleep. At Anastore we recommend taking it preferably in the morning and on an empty stomach.

For sexual activity

If you are concerned about your intimate life and want to try L-citrulline, we also recommend taking citrulline daily, regardless of timing. On days when you plan to have sexual intercourse, you can take it 30 to 60 minutes beforehand.
