Why Citrulline Malate Matters for Muscle Growth#
Citrulline malate is a supplement that combines the amino acid citrulline with malic acid. Citrulline is an amino acid that plays a crucial role in the urea cycle, helping to remove ammonia from the body. Malic acid, on the other hand, is a key component of the Krebs cycle, which generates energy for the body.
The International Society of Sports Nutrition (ISSN) recommends citrulline malate as a potential ergogenic aid for athletes, citing its ability to increase blood flow and reduce fatigue. The American College of Sports Medicine (ACSM) also recognizes citrulline malate as a supplement that may improve exercise performance.
What the Research Says#
Numerous studies have investigated the effects of citrulline malate on exercise performance. A 2010 study published in the Journal of Strength and Conditioning Research found that citrulline malate supplementation increased blood flow and reduced fatigue during high-intensity exercise. Another study published in 2018 in the Journal of the International Society of Sports Nutrition found that citrulline malate improved muscle endurance and reduced muscle soreness after exercise.
A meta-analysis published in 2020 in the journal Nutrients found that citrulline malate supplementation resulted in significant improvements in exercise performance, including increased power output and reduced fatigue. The analysis included data from 17 studies and found that the effects of citrulline malate were most pronounced during high-intensity exercise.
Practical Dosing and Timing Recommendations#
The recommended dose of citrulline malate varies, but most studies use a dose of 2-5 grams per day. It’s essential to note that individual tolerance and response to citrulline malate may vary, so it’s crucial to start with a low dose and gradually increase as needed.
In terms of timing, research suggests that taking citrulline malate 30-60 minutes before exercise may be most effective for improving performance. However, more research is needed to determine the optimal timing and dosing strategy.
Scientific Breakdown#
Citrulline malate works by increasing blood flow and reducing fatigue during exercise. The citrulline component of the supplement helps to increase arginine levels in the body, which can improve blood flow and exercise performance. The malic acid component, on the other hand, helps to generate energy for the body through the Krebs cycle.
Common Myths Debunked#
One common myth surrounding citrulline malate is that it’s a stimulant and can cause jitters or anxiety. However, research suggests that citrulline malate does not have significant stimulatory effects and is generally well-tolerated.
Another myth is that citrulline malate only works for endurance athletes and has no benefits for strength training. However, research suggests that citrulline malate may also improve muscle endurance and reduce muscle soreness after strength training exercise.
Conclusion#
Citrulline malate is a supplement that may improve exercise performance and enhance muscle growth. While more research is needed to fully understand its effects, the current evidence suggests that citrulline malate may be a useful addition to an athlete’s or weightlifter’s supplement regimen. As with any supplement, it’s essential to consult with a healthcare professional or registered dietitian before adding citrulline malate to your routine.
In terms of product recommendations, look for supplements that contain 2-5 grams of citrulline malate per serving and are manufactured by reputable companies. Always follow the recommended dosing instructions and start with a low dose to assess individual tolerance.
Remember, supplementation should always be used in conjunction with a well-balanced diet and regular exercise routine. By combining citrulline malate with a healthy lifestyle, athletes and weightlifters may experience improved performance and enhanced muscle growth.
