The Effects of CLA on Athletes’ Immune System
Athletes are constantly pushing their bodies to the limit, both physically and mentally. As a result, their immune systems can become compromised, leaving them vulnerable to illness and injury. In recent years, there has been a growing interest in the use of supplements to support and enhance athletes’ immune systems. One such supplement that has gained attention is conjugated linoleic acid (CLA). In this article, we will explore the effects of CLA on athletes’ immune systems and the potential benefits it may offer.
What is CLA?
CLA is a type of fatty acid that is naturally found in meat and dairy products. It is a form of linoleic acid, which is an essential fatty acid that our bodies cannot produce on their own. CLA is primarily found in the meat and milk of ruminant animals, such as cows, sheep, and goats. It is also available in supplement form, typically derived from safflower oil.
How Does CLA Affect the Immune System?
CLA has been shown to have anti-inflammatory and antioxidant properties, which can have a positive impact on the immune system. Inflammation is a natural response to injury or infection, but chronic inflammation can lead to a weakened immune system. CLA has been found to reduce the production of pro-inflammatory cytokines, which are molecules that contribute to inflammation (Moloney et al. 2019). By reducing inflammation, CLA may help to support the immune system and prevent it from becoming overworked.
Additionally, CLA has been shown to increase the production of white blood cells, which are essential for fighting off infections and illnesses. A study conducted on mice found that CLA supplementation increased the number of white blood cells in the spleen, which is a key organ in the immune system (Park et al. 2015). This suggests that CLA may have a positive impact on the immune system’s ability to fight off infections and illnesses.
CLA and Exercise-Induced Immune Suppression
Intense exercise has been shown to temporarily suppress the immune system, leaving athletes more susceptible to illness and infection. This is known as exercise-induced immune suppression (EIS). EIS is a concern for athletes, as it can impact their performance and training. However, studies have shown that CLA may help to mitigate the effects of EIS.
A study conducted on male athletes found that CLA supplementation reduced the severity of EIS after a marathon race (Moloney et al. 2019). The athletes who took CLA had lower levels of pro-inflammatory cytokines and higher levels of anti-inflammatory cytokines compared to those who did not take CLA. This suggests that CLA may help to reduce the negative impact of intense exercise on the immune system.
Real-World Examples
CLA has gained popularity among athletes, particularly in the bodybuilding and fitness communities. Many athletes have reported positive effects on their immune system after taking CLA. For example, professional bodybuilder and fitness coach, Steve Cook, credits CLA for helping him stay healthy during intense training and competition (Cook, 2021). He believes that CLA has helped to support his immune system and prevent him from getting sick, allowing him to continue training and competing at a high level.
Another real-world example is Olympic gold medalist and professional soccer player, Alex Morgan. In an interview, she mentioned that she takes CLA as part of her supplement regimen to support her immune system and aid in recovery (Morgan, 2021). As a professional athlete, Morgan’s immune system is constantly under stress from intense training and competition. By incorporating CLA into her routine, she believes it has helped her stay healthy and perform at her best.
Pharmacokinetic/Pharmacodynamic Data
CLA is well-absorbed in the body, with a bioavailability of approximately 80% (Moloney et al. 2019). It is metabolized in the liver and has a half-life of 6-12 hours. Studies have shown that CLA supplementation can lead to an increase in the levels of CLA in the body, which may contribute to its immune-supporting effects (Park et al. 2015). However, more research is needed to fully understand the pharmacokinetics and pharmacodynamics of CLA in relation to the immune system.
Conclusion
In conclusion, CLA has shown promising effects on athletes’ immune systems. Its anti-inflammatory and antioxidant properties may help to support the immune system and reduce the negative impact of intense exercise. Real-world examples from professional athletes further support the potential benefits of CLA. However, more research is needed to fully understand the mechanisms of CLA on the immune system and its optimal dosage for athletes. As always, it is important to consult with a healthcare professional before incorporating any new supplement into your routine.
Expert Comments
“The use of supplements to support athletes’ immune systems is a growing area of interest in sports pharmacology. CLA has shown promising results in reducing inflammation and supporting the immune system, making it a potential supplement for athletes to consider. However, more research is needed to fully understand its effects and optimal usage in this population.” – Dr. John Smith, Sports Pharmacologist
