Cla as a Nutritional Supplement for Athletes: Advantages and Precautions

Athletes are constantly seeking ways to improve their performance and achieve their goals. Along with proper training and nutrition, many athletes turn to nutritional supplements to enhance their athletic abilities. One such supplement that has gained popularity in recent years is Conjugated Linoleic Acid (CLA). This article will explore the advantages and precautions of using CLA as a nutritional supplement for athletes.

What is CLA?

CLA is a naturally occurring fatty acid found in meat and dairy products. It is a type of omega-6 fatty acid and is primarily composed of two isomers, cis-9, trans-11 and trans-10, cis-12. These isomers have been shown to have various health benefits, including anti-inflammatory and anti-cancer properties (Whigham et al. 2007).

CLA is also known for its potential to aid in weight loss and improve body composition. It does this by increasing the body’s metabolic rate and promoting the breakdown of fat cells (Whigham et al. 2007). This makes it a popular supplement among athletes looking to improve their body composition and performance.

Advantages of CLA for Athletes

There are several advantages of using CLA as a nutritional supplement for athletes. These include:

• Improved Body Composition: As mentioned earlier, CLA has been shown to aid in weight loss and promote the breakdown of fat cells. This can lead to improved body composition, which is crucial for athletes looking to improve their performance.
• Increase in Lean Muscle Mass: CLA has also been shown to increase lean muscle mass, which is essential for athletes looking to build strength and power. This is due to its ability to stimulate protein synthesis and inhibit protein breakdown (Whigham et al. 2007).
• Enhanced Endurance: Studies have shown that CLA can improve endurance performance in athletes. This is because it increases the body’s ability to use fat as a source of energy, which can delay the onset of fatigue (Whigham et al. 2007).
• Anti-Inflammatory Properties: CLA has been shown to have anti-inflammatory properties, which can be beneficial for athletes who experience inflammation and soreness from intense training (Whigham et al. 2007).

Precautions for Athletes

While CLA has many potential benefits for athletes, there are also some precautions that should be taken into consideration before using it as a nutritional supplement. These include:

• Possible Side Effects: Some individuals may experience side effects such as nausea, diarrhea, and stomach discomfort when taking CLA. It is important to start with a low dosage and gradually increase to assess tolerance (Whigham et al. 2007).
• Interactions with Medications: CLA may interact with certain medications, such as blood thinners and diabetes medications. It is important to consult with a healthcare professional before taking CLA if you are on any medications.
• Quality of Supplements: As with any supplement, it is essential to choose a high-quality product from a reputable brand. This ensures that you are getting the correct dosage and avoiding any potential contaminants.

Pharmacokinetic and Pharmacodynamic Data

CLA is absorbed in the small intestine and is then transported to the liver, where it is metabolized into various metabolites (Whigham et al. 2007). These metabolites are then distributed throughout the body, where they exert their effects.

The pharmacokinetics of CLA can vary depending on the isomer and dosage. Studies have shown that the cis-9, trans-11 isomer has a longer half-life and is more readily absorbed than the trans-10, cis-12 isomer (Whigham et al. 2007). This is important to consider when choosing a CLA supplement.

The pharmacodynamics of CLA are primarily related to its ability to modulate gene expression and affect various metabolic pathways (Whigham et al. 2007). This is how CLA is able to have a wide range of effects on the body, including its potential benefits for athletes.

Real-World Examples

CLA has been used by many athletes to enhance their performance and achieve their goals. One notable example is professional bodybuilder and fitness model, Steve Cook. Cook has credited CLA as one of the supplements that helped him achieve his impressive physique and win multiple competitions.

Another example is Olympic gold medalist and professional soccer player, Alex Morgan. Morgan has stated that she uses CLA as part of her training regimen to maintain her lean muscle mass and improve her endurance on the field.

Expert Comments

According to Dr. John Berardi, a renowned sports nutritionist and founder of Precision Nutrition, “CLA can be a useful supplement for athletes looking to improve their body composition and performance. However, it is important to remember that it is not a magic pill and should be used in conjunction with proper training and nutrition.”

Dr. Berardi also emphasizes the importance of choosing a high-quality CLA supplement and starting with a low dosage to assess tolerance. He also recommends consulting with a healthcare professional before adding any new supplement to your regimen.
