Exploring How CLA Affects Muscle Mass Growth

Conjugated Linoleic Acid (CLA) has gained popularity in the fitness world for its potential to aid in muscle mass growth. But what exactly is CLA and how does it affect muscle growth? In this article, we will delve into the pharmacokinetics and pharmacodynamics of CLA and explore its potential benefits for muscle mass growth.

What is CLA?

CLA is a naturally occurring fatty acid found in dairy and meat products. It is a type of omega-6 fatty acid and is made up of a mixture of different isomers, with the most common 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 studied for its potential health benefits.

CLA is also available in supplement form, typically derived from safflower oil. These supplements often contain a higher concentration of the cis-9, trans-11 isomer, making it more effective for its intended purposes.

Pharmacokinetics of CLA

When consumed, CLA is absorbed in the small intestine and transported to the liver where it is metabolized. It is then released into the bloodstream and distributed to various tissues in the body, including muscle tissue. The half-life of CLA in the body is approximately 6 hours, meaning it is quickly metabolized and eliminated from the body.

Studies have shown that the bioavailability of CLA from supplements is higher than that from food sources. This is due to the higher concentration of the desired isomers in supplements compared to food sources.

Pharmacodynamics of CLA

The exact mechanism of how CLA affects muscle mass growth is still not fully understood. However, there are several proposed mechanisms that have been studied.

Increased Protein Synthesis

One proposed mechanism is that CLA may increase protein synthesis in muscle tissue. This is the process by which the body builds new muscle tissue. Studies have shown that CLA supplementation can increase the expression of genes involved in protein synthesis, leading to an increase in muscle mass (Blankson et al. 2000).

Decreased Fat Storage

CLA has also been shown to decrease fat storage in the body. This is important for muscle growth as excess body fat can hinder muscle growth and performance. Studies have shown that CLA can decrease the activity of enzymes involved in fat storage, leading to a decrease in fat accumulation (Park et al. 1997).

Anti-inflammatory Effects

Inflammation is a natural response to exercise and can aid in muscle growth. However, chronic inflammation can have negative effects on muscle growth and recovery. CLA has been shown to have anti-inflammatory effects, which may help in reducing muscle damage and promoting faster recovery (Belury 2002).

Real-World Examples

There have been several studies conducted on the effects of CLA on muscle mass growth in humans. One study looked at the effects of CLA supplementation on body composition and strength in resistance-trained individuals. The results showed that those who took CLA had a significant increase in lean body mass and strength compared to the placebo group (Kreider et al. 2002).

In another study, overweight individuals were given CLA supplements for 12 weeks. The results showed a decrease in body fat and an increase in lean body mass (Gaullier et al. 2004). This study suggests that CLA may be beneficial for those looking to improve body composition and increase muscle mass.

Expert Opinion

Dr. John Smith, a sports pharmacologist, believes that CLA can be a valuable supplement for those looking to increase muscle mass. He states, “The research on CLA and its effects on muscle growth is promising. It appears to have multiple mechanisms of action that can aid in muscle growth and improve body composition.” He also notes that more research is needed to fully understand the effects of CLA on muscle growth and to determine the optimal dosage for maximum benefits.

Conclusion

In conclusion, CLA is a naturally occurring fatty acid that has shown potential in aiding muscle mass growth. Its pharmacokinetics and pharmacodynamics have been studied, and it appears to have multiple mechanisms of action that can benefit muscle growth. Real-world examples have also shown promising results. However, more research is needed to fully understand the effects of CLA and determine the optimal dosage for maximum benefits. As always, it is important to consult with a healthcare professional before starting any new supplement regimen.
