CLA Effectiveness In Weight Loss 2019 - Rip-Off or Worth To Try? Here is Why..
What Is Conjugated Linoleic Acid (CLA)
Conjugated linoleic acid (CLA) is a polyunsaturated fatty acid which occurs naturally in meat and dairy products. There are actually 28 different types of CLA; however, only two are of interest which provides numerous health benefits. CLA is also available in supplemental form; however, it should be noted that this is made from chemically adjusting linoleic acid obtained from safflower and sunflower oils. This results in conjugated linoleic acid, which has a different composition as well as the health benefits which it delivers. 
The mechanisms by which CLA works are by increasing fat-burning capabilities, by stimulating the breakdown of fats as well as inhibiting the production of it. It has been used for the treatment of various diseases and conditions, namely high blood pressure, obesity, diabetes, cancer, asthma as well as for building muscle mass. The US Food and Drug Administration has rated CLA as generally recognized as safe (GRAS) and has approved it as a food additive in milk products, meal replacement beverages, and bars as well as fruit juices. 
The average daily intake of CLA is approximately 151mg for women and 212mg for men. Rich sources of CLA include dairy and beef from grass-fed cows. Research conducted by the USDA and Clemson University found that meat from grass-fed cows possesses 10 characteristics which make it better than beef from grain-fed cows, inclusive of higher amounts of CLA between 300 – 500% more. It is also lower in total fat and saturated fat, which has potential benefits in heart health and disease prevention. Furthermore, it is also higher in vitamins and minerals such as beta-carotene, vitamin E, thiamin, riboflavin, calcium, magnesium, and potassium. Additionally, grass-fed beef is also higher in total omega-3 fatty acids as well as there are a healthier omega-6 and omega-3 fatty acids ratio. Finally, beef from grass-fed cows is higher in vaccenic acid than that found in beef from grain-fed cows; vaccenic acid can be also be converted into CLA which further increases the content found in beef from grass-fed cows. back to menu ↑
Facts About Conjugated Linoleic Acid
- When CLA is fed to mice, their body fat is reduced by 60 percent.
- CLA is a mixture of over 28 isomers of linoleic acid.
- CLA was first discovered in 1987 by Dr. Pariza of the University of Wisconsin
- CLA is considered to be “good fat.”
- Conjugated linoleic acid was first isolated from a fried hamburger.
- The best source of conjugated linoleic acid is beef, and dairy obtained grass-fed cows.
- CLA is the first substance that has been discovered by a University which has been approved by the US FDA as a GRAS substance.  
Foods Containing Conjugated Linoleic Acid
Conjugated linoleic acid may be obtained from foods such as butter from grass-fed cows, eggs, dairy products such as cream, milk, cheese or yogurt obtained from sheep, goats, and cows, grass-fed beef as well as grass-fed lamb and veal. Additionally, CLA may also be obtained from supplements in various forms of capsules, powder, or tablets. back to menu ↑
Conjugated Linoleic Acid: Is It Bad For You?
Conjugated linoleic acid is safe when obtained from food sources, and when taken as a supplement, it is also safe to otherwise healthy individuals when taken as recommended. There are, however, some concerns for persons in a specific class and those suffering from certain diseases and disorders. For persons with bleeding disorders taking CLA may worsen this condition as it slows down the clotting process. Additionally, persons with diabetes or metabolic syndrome should also avoid CLA as it may worsen the symptoms of the former and increases the risk of developing diabetes in the latter. Furthermore, if you have or had surgery, it is recommended that you avoid CLA as it may delay healing. For children and pregnant or nursing women, CLA should also be avoided so as to prevent complications. back to menu ↑
Benefits Of Conjugated Linoleic Acid
The benefits of Conjugated linoleic acid include weight loss, increased muscle mass, lower cholesterol and blood sugar levels, boost the immune system, high blood pressure, cancer, and arthritis. CLA plays an integral role in weight management in that it increases the basal metabolic rate or index (BMI), that is, it increases the rate which food is converted to energy, therefore, giving the resultant effect of increasing one’s energy as well as fat that the body stores . It should be noted that CLA does not actually make one loses weight what it does is that it quickly converts fat into energy, and as fats are consumed, they are also burned up. Therefore, CLA inhibits any excess fat stores from forming. 
CLA also has functionality in bodybuilding as it increases muscle building capabilities as well as repairs damaged muscle tissues. CLA also provides a protective effect as it relates to muscle building due to the fact that whenever a muscle is built, CLA prevents these muscles from being broken back down. 
CLA plays a role in cholesterol and blood sugar regulation, which may also reduce the risk of heart disease and enhances overall heart health. Additionally, it helps in the treatment of diabetes as it lowers blood glucose levels and improves insulin sensitivity. 
Hay fever, also known as allergic rhinitis occurs when the immune system reacts to some kind of allergen in the atmosphere, be it from trees or flowers. It is characterized by nasal congestion, runny nose with clear mucus, sneezing, itchy and watery eyes. Taking CLA for 12 weeks alleviates these symptoms and improves this condition. Asthma is a life-threatening respiratory condition which is characterized by coughing, wheezing, chest tightening, and shortness of breath. This condition may be treated using CLA when taken for 12 weeks. CLA renders this treatment by inhibiting the enzyme 5-lipoxygenase, which breaks done arachidonic acid, the causative agent in asthma attacks. Conjugated linoleic acid is converted into Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA) both of which exert anti-inflammatory effects on the respiratory system, thereby alleviating these symptoms. 
CLA may also be used to treat Rheumatoid arthritis, a condition in which the immune system does not function normally in that, instead of providing protection, the joints of the body are adversely affected. Symptoms of this condition include swelling and pain in the joints, damage to the tissues, and cartilage in the joints as well as decreased mobility. back to menu ↑
Negative Impact Of CLA On The Body
Conjugated linoleic acid obtained from food sources are safe for otherwise healthy individuals; however, when obtained from supplements it may pose some problems or cause complications in individuals who are suffering from certain conditions. Side effects which may be encountered are fatigue, diarrhea, nausea, vomiting, loose stools, heartburn, throat irritation, insulin resistance, and acid indigestion. The fatigue experienced due to the supplement may affect one’s sleep patterns as more sleep is required in order to feel rested. If diarrhea occurs as a result of CLA, there is also the risk of additional complications such as cramping, bloating, and dehydration, which further compounds the problem as dehydration may also cause dizziness, dry skin, or headache. 
At very high doses, CLA may cause more severe side effects such as rash, limb swelling, difficulty breathing, hyperglycemia (high blood sugar), increased C-reactive protein which is indicative of inflammation associated with other underlying conditions. Another side effect of high doses of CLA is decreased amounts of low-density lipoproteins, which may lead to other health conditions. back to menu ↑
How To Minimize Exposure
CLA obtained from foods has no side effects associated with it; however, there are some mild to moderate side effects which may occur when it is obtained in supplemental form. Therefore in order to minimize one’s exposure, it is recommended that all supplemental forms of CLA be avoided.back to menu ↑
