L-citrulline is a protein-free semi-essential amino acid. It’s an ideal supplement for people involved in high-intensive exercise such as weightlifting and sprinting as citrulline ingestion can indirectly increase nitric oxide production. Citrulline also plays a role in the urea cycle, one of your body’s vital processes.
Take 3 g (3 scoops) either 1 hour before training or divided into morning and evening meals.

L-citrulline is a protein-free semi-essential amino acid. Citrulline is said to be non-protein, because unlike other classic amino acids, food does not tend to provide citrulline.
Only watermelon offers a little (about 1 g per kilo).
Consequently, all our citrulline has to be synthesised from the intestinal destruction of various other amino acids such as glutamine and arginine. On the other hand, in the kidneys, citrulline is largely converted into arginine.
Please consult your healthcare professional before use.

Scientists long thought that citrulline was only a metabolic intermediary with little physiological influence (2). In other words, for glutamine to convert to arginine, you have to go through an intermediate step, which is the conversion of glutamine into citrulline; then, the kidneys convert citrulline into arginine. But citrulline by itself was not presumed to have any effect on our bodies.
It was in 1985 that researchers noted that blocking the intracellular production of citrulline inhibited the growth of animals (3). Reverse experiments were then carried out, in which rats were fed half their usual diet for 12 weeks, with or without citrulline supplementation (3). Muscular anabolism remained twice as high in rats receiving citrulline than in those subjected to calorie restriction alone. In the end, with citrulline, the muscles ended up 40% bigger (4). This anabolic effect of citrulline was then confirmed in humans (5-6-7-8-9).
Effects of citrulline
Taking citrulline increases arginine levels in the same way as taking L-arginine directly (12-13). Arginine supplements are partially deteriorated by digestion, which is not the case with citrulline (14). The latter benefits from almost perfect absorption.
With oral consumption, losses of citrulline via urine are minimal, which proves that the body's absorption and retention capacities are excellent, even at high doses (15). Therefore, 3 to 6 g of citrulline can double the level of arginine in the blood (16).
Citrulline and NO
Sporting activity induces a decrease in the level of citrulline in the blood (19-20). For example, after physical exertion, citrulline levels collapse by almost 50%, indicating that intense sporting activity increases our need for citrulline, but the body doesn't respond to this increased demand by increasing the rate of conversion of glutamine or arginine to citrulline (21).
One of the reasons why exercise consumes citrulline is because it forces the body to produce more NO, which in turn wastes citrulline (19). Whether we are athletic or feeling unwell, paradoxically, it is at times when we have an increased need for citrulline that our body starts to produce less of it (28). The only way to counteract this decline is to supplement with Nutrimuscle L-citrulline base.

You feel a slight boost, and have better concentration. I take only 500 mg, because it is very expensive to buy. But the results are visible, and you can really feel the increase in focus and the energy over time. I've only been using it for a week, so we'll see after a month.

I must say that in my case, every other time, I manage to have good sensations. Combining it with glycerol and bicarbonate there is a significant plus on strength.

L-Citrulline is an essential supplement for the body and the sportsman. I have been taking L-Citrulline for a few years and I am very satisfied! It replaces many other supplements that are supposedly good for the human body. The first thing to understand is how your body works and what it needs! Take care of yourselves.

Mixing it with L Arginine as suggested by Nutrimuscle, there is a real increase in muscle congestion.

Hello, Having purchased 1300g of Citruline powder, I asked if it was possible to have a second doser for someone I share the product with. I was told that it was not possible to send just one dispenser and that I had to find one elsewhere. This is obviously impossible since each product has its own density. THANK YOU NUTRIMUSCLE! That's what I call service.
