Conjugated Linoleic Acid (CLA) is used for weight loss, muscle building, reducing inflammation, and promoting heart health due to its potential metabolic effects.
What Is Conjugated Linoleic Acid Used For? | A Complete Overview of Its Benefits
Conjugated Linoleic Acid, or CLA, is a type of polyunsaturated fatty acid found naturally in meat and dairy products. Over the years, CLA has gained popularity as a dietary supplement, particularly among fitness enthusiasts and those seeking weight loss support. But what is Conjugated Linoleic Acid used for? CLA is primarily used for its potential benefits in weight management, fat reduction, muscle building, and heart health. Additionally, research suggests that CLA has anti-inflammatory properties and may play a role in improving metabolic function.
In this article, we'll explore the science behind CLA, its potential health benefits, and how it works in the body. We'll also look at how much CLA is recommended, whether you should consider it as part of your diet, and any potential side effects associated with its use.
Understanding What Conjugated Linoleic Acid Is
Conjugated Linoleic Acid (CLA) is a naturally occurring fatty acid found in meat from grass-fed animals and dairy products. It is one of the most studied types of fats in terms of health benefits and biological activity. CLA exists in different forms, known as isomers, and these various forms have been shown to affect fat metabolism, reduce inflammation, and support muscle growth.
1. Where Does CLA Come From?
CLA is predominantly found in the meat and milk of ruminant animals like cows, goats, and sheep. The levels of CLA in these products are influenced by the animals’ diet, with higher amounts found in products from grass-fed animals.
- Example: Grass-fed beef and organic dairy products contain higher levels of CLA than conventionally raised cattle, making these sources more nutrient-dense.
2. How CLA Works in the Body
CLA influences metabolism in a way that may help reduce body fat and increase lean muscle mass. It is thought to work by altering enzymes involved in fat storage and breakdown, as well as by modulating the body’s response to insulin.
- Example: CLA supplementation may help inhibit the activity of lipoprotein lipase, an enzyme responsible for fat storage, while promoting the breakdown of fat for energy.
Table 1: Natural Sources of CLA
| Food Source | Approximate CLA Content (per gram of fat) | Benefit of Grass-Fed Products |
| Grass-Fed Beef | 4.3-5.6 mg | Higher CLA content due to diet |
| Grass-Fed Dairy Products | 3.4-5.5 mg | Richer in CLA and other healthy fats |
| Lamb | 5.6 mg | High CLA concentration in meat |
Health Benefits of Conjugated Linoleic Acid
The potential health benefits of CLA extend beyond just fat loss. CLA has been studied for its role in improving body composition, enhancing muscle mass, reducing inflammation, and supporting heart health. Here's a closer look at some of the key benefits of CLA.
1. CLA for Weight Loss
One of the most popular uses of CLA is in weight management. CLA is believed to help reduce body fat by increasing the breakdown of fat cells and inhibiting fat storage. Several studies suggest that CLA may be effective in reducing body fat and improving body composition, although results can vary from person to person.
- Example: A meta-analysis of multiple studies found that people who took CLA supplements experienced a modest reduction in body fat, typically around 0.2 pounds per week compared to those who didn't take CLA.
2. Enhancing Muscle Growth
In addition to its potential fat-burning effects, CLA may also help increase lean muscle mass. This makes it particularly popular among athletes and bodybuilders who are looking to build muscle while reducing fat.
- Example: Some research indicates that CLA can help promote muscle retention and growth, especially when combined with resistance training.
3. Anti-Inflammatory Properties
CLA has been shown to possess anti-inflammatory properties, which may help reduce the risk of chronic diseases associated with inflammation, such as heart disease and arthritis. By reducing inflammation, CLA may improve overall health and longevity.
- Example: A study published in The American Journal of Clinical Nutrition found that CLA supplementation reduced markers of inflammation in overweight individuals.
4. Heart Health Benefits
There is some evidence to suggest that CLA can have a positive effect on heart health by reducing cholesterol levels and improving overall lipid profiles. CLA may help lower LDL (“bad”) cholesterol and increase HDL (“good”) cholesterol, which can reduce the risk of cardiovascular diseases.
- Example: Animal studies have shown that CLA can help reduce the buildup of arterial plaque, which is associated with atherosclerosis, a major risk factor for heart disease.
Table 2: Key Health Benefits of CLA
| Health Benefit | How CLA Contributes | Example of Effect |
| Weight Loss | Reduces fat storage, promotes fat breakdown | 0.2 pounds fat loss per week in some studies |
| Muscle Growth | Increases lean muscle mass | Supports muscle retention during exercise |
| Anti-Inflammatory Properties | Reduces inflammation, lowers risk of chronic disease | May lower inflammation markers |
| Heart Health | Improves cholesterol levels, reduces plaque buildup | May reduce LDL cholesterol and improve HDL |
How Much CLA Should You Take?
The appropriate dosage of CLA depends on your goals and overall health. While CLA is found naturally in food, many people choose to supplement with CLA to reach higher concentrations that may promote fat loss and other benefits. Here's a breakdown of typical CLA dosages and how to incorporate CLA into your diet.
1. Recommended Dosage for Weight Loss
For those looking to use CLA for fat loss, studies typically use doses ranging from 3 to 6 grams per day. This level of supplementation is thought to be effective for reducing body fat while maintaining lean muscle mass.
- Example: A common CLA supplement regimen might involve taking 1 to 2 grams of CLA with each meal, totaling 3 to 6 grams per day.
2. Dosage for Muscle Building
To support muscle growth and recovery, athletes often take between 3 and 5 grams of CLA per day. Combining CLA with a strength training routine can help maximize muscle retention while promoting fat loss.
- Example: A bodybuilder might take 1 gram of CLA three times a day, in addition to a balanced diet rich in protein and carbohydrates.
3. Incorporating CLA-Rich Foods into Your Diet
If you prefer to get your CLA from natural sources, including grass-fed meat and dairy in your diet can help. However, it's important to note that food sources alone may not provide the high levels of CLA that supplementation can offer.
- Example: A diet that includes grass-fed beef, lamb, and full-fat dairy products can provide natural CLA, but supplementation may still be necessary for higher dosages.
Table 3: Recommended Dosage of CLA for Various Goals
| Health Goal | Recommended Daily Dosage | Method of Intake |
| Weight Loss | 3-6 grams | 1-2 grams per meal, with food or supplement |
| Muscle Growth | 3-5 grams | Take before or after workouts |
| General Health | 1-3 grams | Achievable through diet or lower supplementation |
CLA in Weight Loss and Bodybuilding
Many people turn to CLA supplements to aid in weight loss and bodybuilding. By helping to reduce fat while preserving muscle mass, CLA is often marketed as a dual-purpose supplement for those looking to improve body composition.
1. CLA for Body Fat Reduction
CLA is believed to support fat loss by influencing enzymes that affect fat storage and fat breakdown. Research has shown that CLA may reduce body fat over time, although the results are often modest. CLA works best when combined with a healthy diet and regular exercise.
- Example: A study published in The Journal of Nutrition found that individuals taking CLA supplements lost slightly more body fat compared to those who didn't, especially when combined with regular physical activity.
2. Building Lean Muscle Mass with CLA
Bodybuilders and athletes often take CLA to help maintain or increase muscle mass during cutting phases, where the goal is to lose fat while retaining muscle. By supporting lean muscle retention, CLA may help improve body composition without the loss of muscle that sometimes accompanies fat loss.
- Example: In one study, athletes who supplemented with CLA and engaged in strength training experienced increased muscle retention and fat loss compared to those who did not take CLA.
Table 4: CLA for Weight Loss and Bodybuilding
| Benefit for Athletes | How CLA Supports Fitness Goals | Example of Results |
| Fat Reduction | Reduces fat storage, promotes fat breakdown | Slight increase in fat loss with exercise |
| Muscle Retention | Helps maintain lean muscle during fat loss | Improved muscle retention during cutting |
| Overall Body Composition | Supports balance between fat loss and muscle gain | Enhanced muscle definition with training |
Side Effects and Safety of CLA
