What is CLA?
CLA or conjugated linoleic acid is a polyunsaturated omega-6 fatty acid and is found naturally in the digestive system of goats, cows, buffalos, and sheep.
Meat and dairy products are the best natural sources for CLA in the human diet.
CLA has shown to inhibit the activity of enzymes like lipoprotein lipase (1). LPL is responsible for picking up fat cells from the blood circulation and converting it to body fats for storage.
Hence, CLA plays a significant role in breaking down body fat, inhibiting the conversion of energy from body fat, and destroying fat cells (2).
Summary: CLA is a fatty acid that prevents the body from storing fat and promotes fat-burning action.
CLA Supplements and Weight Loss
Naturally-available CLA may not be enough to bring about the desired effects. Therefore, you may resort to over-the-counter supplements like Tonalin and CLA-80.
Though these supplements claim to burn fat and aid in weight loss, studies have shown mixed results.
In September 2015, the Journal of the International Society of Sports Nutrition published a review on the basis of 16 studies conducted from 2010 to 2015 (3).
According to the review, 9 studies revealed no benefits of CLA Those cases that showed a positive impact on the body composition had physical activity combined with CLA supplementation.
On the other hand, a study conducted on postmenopausal women showed considerable improvement in fat mass and body weight when they were given 5.5grams of mixed CLA for a period of 16 weeks (4).
CLA supplements can be coupled up with other supplements when the goal is not just limited to weight loss. Here are a few of the most common examples of supplements taken along with CLA-
- Acetyl carnitine plus CLA- Due to its ability to cross blood-brain barrier acetylcarnitine, commonly called ALCAR, helps in supporting brain health and improving focus and memory while CLA helps in weight management (5).
- CLA with Quadracarn- Quadracarn, as the name suggests is a dietary supplement consisting of 4 types of carnitine namely L carnitine, N-Acetyl L-Carnitine HCl, L-Carnitine L-Tartrate, and Propionyl L-Carnitine. It helps in muscle building, faster recovery after a strenuous workout, and promotes longevity. As a fat burner, Quadracarn is inadequate and hence the combination of CLA with Quadracarn works great.
- CLA Carnitine Collagen- Collagen promotes healthy and supple skin and strengthens the joints. Hence, these three C’s can guarantee you nothing less than a healthy mind and a fit body!
Summary: CLA supplements have shown mixed results in terms of weight loss. Few studies indicate that they bring about a significant reduction in weight whereas some fail to show any positive impact.
The Benefits and Side Effects of CLA

CLA vs Thermogenic Supplements
Thermogenesis is the process by which our body produces heat by burning calories. ic Thermogenic supplements are meant to boost your body’s metabolism (8).
When taken half an hour to an hour before workouts, these supplements may help you perform intense exercises for a longer duration.
One of the most common ingredients of thermogenic supplements is caffeine. Owing to its stimulant properties, caffeine can pose sleeping difficulties in caffeine-sensitive individuals (9).
Moreover, caffeine can have serious side effects such as rapid or erratic heartbeat.
On the other hand, CLA supplements have proved to be comparatively safe. It is safe for the heart as it prevents the thickening of arteries and enhances immunity.
Summary: CLA supplements are safe when compared to thermogenic supplements as the latter contains caffeine as its main ingredient.
What is L Carnitine?
L carnitine is an amino acid that is formed inside our kidney and liver with the help of two other amino acids namely, lysine and methionine.
Meat, milk, fish, and poultry are rich in carnitine with beef being the best source as just 4 ounces of beef contains 56 to 62 milligrams of carnitine (10).
L carnitine acts as a transporter of long-chain fatty acids and carries them to the cell’s mitochondria so that these fatty acids can be burnt to release energy.
L carnitine increases the amount of fat that the body can burn during a workout or even while resting. Studies have shown that the efficacy of the fat-burning effect of L carnitine is more during a training session than during rest.
Summary: L Carnitine, basically an amino acid, is a fatty-acid transporter and boosts the fat-burning action during a workout.
L Carnitine Supplements for Endurance Training
Due to its function of promoting fatty acid oxidation, L carnitine supplements are often marketed as a weight-loss supplement.
According to the National Institutes of Health Office of Dietary Supplements, L carnitine can bring about only a moderate bodyweight reduction whereas another systematic review published in Obesity Reviews suggests that carnitine can assist in maintaining a healthy body weight (11), (12).
It can be extremely effective in athletes for enhanced physical performance. In a study on a group of 25 men carnitine and placebo were given along with strength training for 9 weeks (13).
Those who were put on carnitine showed an improvement in their antioxidant capacity and strength. Hence, it was concluded that carnitine can increase athletic performance.
Summary: L carnitine can help in body weight maintenance and improve athletic performance.
