What is L-Citrulline?

L-citrulline is a natural amino acid that occurs in our body. It can be found in foods such as watermelon and is also produced by the body itself. Our body converts L-citrulline into another amino acid called L-arginine. Due to European legislation, we cannot mention the possible benefits of this supplement.

How is L-Citrulline produced?

L-citrulline can be produced as a dietary supplement through a fermentation process. Specific bacterial strains are used to convert precursor molecules, such as glucose or other sugars, into L-citrulline. This product is then purified and processed into various forms, such as powders, capsules and tablets.

In addition, L-citrulline can also be obtained from natural sources, such as watermelons, which are naturally rich in this amino acid. The highest concentrations are in the peel and pulp close to the peel. By extracting and purifying these parts of the watermelon, it can be obtained as a supplement.

Difference between L-Citrulline and L-Citrulline Malate

There are two varieties of citrulline that are commonly found in supplements. Both have similar properties, but there are some important differences:

Get L-Citrulline from food

L-citrulline is found in several healthy foods, although concentrations are usually low. Below are some examples:

• Watermelon: The best known source, with concentrations ranging from 100 mg to more than 250 mg per 100 grams of pulp.
• Cucumbers: About 10-15 mg per cup of cut.
• Other melons: Cantaloupe and honeydew melon also contain small amounts.
• Pumpkins: About 250-300 mg per 150 grams.
• Crustaceans and shellfish: Small amounts present in shrimp and crab.

If you want to experience the benefits of L-citrulline, it is often best to choose a supplement with a higher dose than what you can get from diet alone. Always consult your doctor or a certified dietitian before use.

Is using L-Citrulline safe?

L-citrulline has long been known as a safe dietary supplement that supports certain body processes. However, it can affect how some medications work and can lower blood pressure. People who are already taking blood pressure lowering medications should exercise caution and consult their doctor first before taking this supplement. Supplements are not a substitute for a healthy diet and lifestyle, but they can be a valuable addition.

If you are taking medication or are being treated by a doctor, always inform your doctor about the use of supplements. This allows your doctor to monitor possible side effects or drug interactions.

How do you use L-Citrulline?

There are no specific recommendations for taking L-citrulline on an empty stomach. It can be taken at any time of the day, with or without food. Many people like to take it before exercising, while others prefer to take it at a different time. It is better absorbed when taken with other nutrients such as carbohydrates.

How much L-Citrulline per day?

The recommended daily dose is up to 6 grams, dissolved in water, preferably during a meal in the morning or evening. For use as a pre-workout, take approximately 30 minutes before training. Most studies show that up to 6 grams is most effective.

Additional instructions

Do not take L-Citrulline if you:

• Nitrates used for heart disease.

L-Citrulline effect, advice and European legislation

Because you can buy L-citrulline from us, unfortunately we cannot share any scientific articles or possible health benefits. We would like to refer you to non-profit orthomolecular sites or Pubmed for more information. You can also ask us for advice via WhatsApp or our contact button at the bottom right. It is always wise to consult a doctor or certified dietitian before starting to use any supplement.

Does L-Citrulline affect intermittent fasting?

If you are fasting for religious reasons, any food intake is considered breaking the fast, including supplements such as L-citrulline. However, if you are fasting for health reasons (such as intermittent fasting), taking this powder form will probably not cause significant disruption. Please note: capsules or pills can interrupt the fast due to added substances.

Our pure L-citrulline powder contains only the amino acid and is low in calories, so it does not affect your insulin or blood sugar levels. Although it contains no calories itself, it can be converted into arginine, which contributes to the synthesis of nitric oxide (NO) in the body. Arginine can be converted into glucose in the liver, which provides calories.
