Weider Product description Weider Premium Citrulline
L-Citrulline is a nonessential amino acid that plays a key role in the urea cycle and, above all, in the production of nitric oxide (NO) in the body. CitruSyn® is a pure and stable, patented form of this amino acid designed for improved bioavailability.
Unlike direct supplementation with L-arginine, which is rapidly metabolized, citrulline is more efficiently converted to arginine in the kidneys, leading to a longer-lasting increase in blood arginine levels and, consequently, higher NO production.
This mechanism promotes vasodilation—the widening of blood vessels—which improves blood flow to the muscles, increases the delivery of oxygen and nutrients, and reduces the accumulation of waste products such as lactate.
According to systematic reviews and meta-analyses, citrulline supplementation at doses of 3–6 g per day can improve both aerobic and anaerobic performance, for example, by extending time to exhaustion by 10–20% during endurance activities or increasing the number of repetitions in strength training.
Other studies show a reduction in the subjective feeling of fatigue (RPE—rating of perceived exertion) and muscle soreness after exercise, which is associated with better recovery due to improved removal of metabolites.
Pomegranate extract is rich in polyphenols such as punicalagins and ellagitannins, which have strong antioxidant properties and influence endothelial function in blood vessels.
These compounds protect NO from oxidative damage caused by free radicals, which prolongs its biological activity and enhances its effectiveness in regulating blood flow.
Studies show that regular consumption of pomegranate extract stimulates the activity of endothelial NO synthase (eNOS), leading to improved vasodilation and a reduction in inflammatory markers in the vascular system. This has a direct impact on performance: for example, improved blood flow can prolong time to exhaustion during running and reduce fatigue, thanks to higher levels of nitrates and polyphenols that boost NO production. Furthermore, it helps protect against atherosclerosis by improving endothelial health and reducing platelet adhesion, which is beneficial for long-term cardiovascular support in active individuals exposed to oxidative stress from training. When combined with citrulline, it enhances the overall effect on blood flow and recovery. AstraGin® is a proprietary blend of Asian herbal extracts that influences the expression of transporters in the intestinal mucosa, thereby improving nutrient absorption.
According to in vitro and in vivo studies, it can increase the absorption of amino acids, peptides, folate, and other substances by up to 60% by regulating gene expression and protein synthesis in blood cells. This means that, in the context of this product, it helps maximize the utilization of citrulline and vitamins, leading to more effective results without the need for higher doses during exercise, which supports immunity and reduces inflammation.
