L-citrulline is an amino acid that is converted into L-arginine in the body and thus promotes the production of nitric oxide (NO). Nitric oxide dilates the blood vessels, which improves blood flow and ensures an optimal supply of oxygen and nutrients to the muscles. In the form of L-citrulline malate, a combination of L-citrulline and malate (malic acid), this amino acid is particularly popular among athletes because it can have a positive effect on training due to its effect on blood flow and energy production. We currently use L-citrulline in our pre-workout booster Crank and Crank Pump Pro. We have already received positive feedback on the effectiveness of L-citrulline.

L-citrulline for strength athletes and bodybuilders

L-citrulline is a real insider tip for bodybuilders and strength athletes for a number of reasons. Firstly, it can promote the ‘pump’ – the feeling when the muscles are supplied with more blood during training and appear larger. This pump is not only visually motivating, but also supports the supply of nutrients to the muscles and improves performance.

In addition, L-citrulline can help to delay fatigue. The amino acid ensures that the muscles are better supplied with oxygen, which enables longer and more intense training sessions. Especially during heavy strength training or endurance-focused workouts, L-citrulline can be the deciding factor in getting a few more reps out.

For the best results, we recommend taking about 5 g of L-citrulline malate about 30 minutes before training. This dosage ensures that the effect sets in in good time and that the desired effect on pumping, endurance and regeneration can unfold. It is particularly practical that L-citrulline in powder form can be easily combined with other training boosters and supports fast absorption in the body.

Important: Dietary supplements should only be used as a supplement to a balanced and healthy diet, as well as a healthy lifestyle.

How to take L-Citrulline

• Take 5g L-citrulline malate 20-30 minutes before training with sufficient liquid
• In combination with other NO-boosting supplements and boosters (AAKG, Crank Pump Pro, Crank, Crank Ultimate, etc.), the pump effect can be even more pronounced

FAQ L-Citrulline

How does ESN L-Citrulline work?

L-citrulline malate is converted into L-arginine in the body, which increases the production of nitric oxide (NO). NO dilates blood vessels and improves blood flow, which provides the muscles with a better supply of oxygen and nutrients. These effects can increase endurance, promote recovery and intensify the ‘pump’ effect that many athletes strive for during training.

Are there any side effects I need to be aware of?

L-citrulline malate is generally well tolerated. However, some people may experience gastrointestinal discomfort if taken in too high doses. It is advisable not to exceed the recommended dosage and to consult a doctor in advance if you are unsure.

Can I combine L-citrulline with other boosters?

Yes, L-Citrulline Malate can be combined with other NO-boosting supplements such as AAKG, Crank Pump Pro or other pre-workout boosters. This combination can further enhance the pump effect, which is particularly beneficial for intense training sessions.

Is ESN L-Citrulline also suitable for vegetarians and vegans?

ESN L-Citrulline is vegan. It is therefore suitable for vegans.

Who should not take it?

L-citrulline is not usually suitable for people with certain medical conditions, such as severe cardiovascular disease, without first consulting a doctor. Pregnant and breastfeeding women should also seek medical advice before taking L-citrulline.
