Citrulline

Citrulline is a product category containing dietary supplements with the non-essential amino acid citrulline, which is popular in pre-workout supplements. It is a common substance found in small amounts in the food we consume, for example, in a watermelon. However, it is also naturally present in our bodies, where it serves various functions.

One of its key roles is the ability to transform into the amino acid arginine. From there, it forms nitric oxide, which affects the widening of blood vessels and subsequently, the blood flow to muscles. This is closely related to the delivery of oxygen and nutrients to the working muscles and the removal of metabolic waste produced during physical activity. All these benefits make citrulline a very popular ingredient in pre-workout supplements, which help athletes achieve peak performance.

What is the difference between L-citrulline and L-citrulline malate?

You will often find citrulline in dietary supplements as either L-citrulline or L-citrulline malate. In the latter case, L-citrulline creates a complex with the malic acid salt, known as malate. This complex gets involved in the Krebs cycle in the body, which produces ATP — the primary source of cellular energy. Therefore, the L-citrulline malate complex can offer even more benefits to athletes than L-citrulline alone.

For whom is citrulline suitable?

Citrulline is ideal for all athletes aiming to achieve peak performance and get the most out of every workout. It is therefore sure to be appreciated by powerlifters, weightlifters, bodybuilders, crossfitters, and other strength athletes. However, it's also suitable for endurance athletes like runners and cyclists. Additionally, team sports athletes such as footballers, hockey players, or basketball players, as well as martial artists, like boxers or MMA fighters, can all benefit from what it has to offer.

How to take citrulline?

You can take citrulline as a standalone product in the form of capsules or soluble powder. However, it's also part of complex pre-workout blends and NO supplements. Regardless of the form you choose, make sure to take citrulline according to the recommended dosage, ideally 20–60 minutes before exercise to allow for maximum absorption and to fully utilize its potential during your workout session.
