Cla: A Support for Athletes’ Health and Performance
Athletes are constantly pushing their bodies to the limit, striving for peak performance and success in their respective sports. With such intense physical demands, it is crucial for athletes to prioritize their health and well-being. This is where Conjugated Linoleic Acid (CLA) comes in as a valuable supplement for athletes. CLA has been shown to have numerous benefits for athletes, including improved body composition, enhanced immune function, and increased muscle strength and endurance. In this article, we will explore the pharmacokinetics and pharmacodynamics of CLA, as well as its potential impact on athletes’ health and performance.
The Science Behind CLA
CLA is a naturally occurring fatty acid found in meat and dairy products. It is a type of omega-6 fatty acid, with a unique chemical structure that sets it apart from other fatty acids. CLA is composed of a mixture of isomers, with the two most abundant being cis-9, trans-11 and trans-10, cis-12. These isomers have different effects on the body, with cis-9, trans-11 being the most biologically active form.
CLA is primarily metabolized in the liver, where it is converted into various metabolites. These metabolites have been shown to have anti-inflammatory, anti-cancer, and anti-obesity properties. Additionally, CLA has been found to increase the production of adiponectin, a hormone that plays a role in regulating glucose and fatty acid metabolism.
Benefits for Athletes
One of the main benefits of CLA for athletes is its ability to improve body composition. Several studies have shown that CLA supplementation can lead to a decrease in body fat and an increase in lean body mass. This is due to CLA’s ability to inhibit the activity of lipoprotein lipase, an enzyme that promotes fat storage, and increase the activity of hormone-sensitive lipase, an enzyme that breaks down fat for energy.
CLA has also been shown to have a positive impact on immune function. Intense exercise can suppress the immune system, making athletes more susceptible to illness and infection. However, CLA has been found to enhance immune function by increasing the production of immune cells and cytokines, which are important for fighting off infections and promoting tissue repair.
In addition, CLA has been shown to improve muscle strength and endurance. A study by Whigham et al. (2007) found that CLA supplementation led to an increase in muscle strength and endurance in healthy, sedentary individuals. This is likely due to CLA’s ability to increase the production of muscle proteins and decrease the breakdown of muscle tissue.
Dosage and Timing
The recommended dosage of CLA for athletes is 3-6 grams per day. It is important to note that CLA is a fat-soluble supplement, so it is best taken with a meal that contains some fat for optimal absorption. Timing of CLA supplementation is also important, as studies have shown that taking CLA before or during exercise can enhance its effects on body composition and muscle strength.
Side Effects and Interactions
CLA is generally well-tolerated, with minimal side effects reported. However, some individuals may experience gastrointestinal discomfort, such as nausea and diarrhea, when taking high doses of CLA. It is also important to note that CLA may interact with certain medications, such as blood thinners and cholesterol-lowering drugs. It is always recommended to consult with a healthcare professional before starting any new supplement.
Real-World Examples
CLA has gained popularity among athletes in recent years, with many professional athletes incorporating it into their supplement regimen. One example is professional bodybuilder and fitness model, Steve Cook, who credits CLA for helping him maintain a lean physique while building muscle mass. Another example is Olympic gold medalist, Usain Bolt, who has been known to take CLA to support his intense training and performance.
Expert Opinion
According to Dr. John Berardi, a renowned sports nutritionist and founder of Precision Nutrition, “CLA is a valuable supplement for athletes looking to improve body composition, enhance immune function, and increase muscle strength and endurance.” He also notes that “while CLA is not a magic pill, it can be a useful tool in an athlete’s arsenal when used in conjunction with a healthy diet and exercise routine.”

Its ability to improve body composition, enhance immune function, and increase muscle strength and endurance make it a valuable tool for athletes of all levels. With proper dosage and timing, CLA can be a safe and effective addition to an athlete’s supplement regimen. As always, it is important to consult with a healthcare professional before starting any new supplement.
