L-carnitine and Omega-3 Fatty Acids Support Weight Loss

When it comes to losing weight the body must be able to effectively burn fat deposits. Many body builders, professional athletes and individuals that have successfully lost weight have successfully utilised the synergistic combination of L-carnitine and omega-3 fatty acids. Together, these natural compounds work to elevate energy levels and burn fat.

Carnitine and fat metabolism

l-caritine and omega 3 for weight lossThe amino acid L-carnitine is found in almost every cell in the body. It is created from two other amino acids, methionine and lysine. L-carnitine is an effective fat burner as one of its roles it to transfer stored fat into the cells to be metabolised for energy.

Increasing the concentrations of carnitine in the muscles can help to elevate fat-burning potential and boost energy levels.  However, to make the most out of the weight-loss mechanisms associated with carnitine, omega-3 fatty acid intake should also be increased.

Benefits of omega-3 fatty acids

Omega-3 fatty acids are essential for the body. They help to maintain a healthy cardiovascular function, lower inflammation, support healthy bones, and enhance cognitive function. These are just a few of the roles these fatty acids play within the body. When it comes to weight loss, omega-3 fatty acids enhance the actions of carnitine.

Fat loss accelerated by carnitine and omega-3 fatty acids

Cells contain two layers of fats or lipids. The type of fat consumed in the food will influence the type of fat stored in the cells. When the body has access to more omega-3s the cells within the body will be healthier.  Consequently the cells become more sensitive to insulin. This has important benefits for carnitine loading.

“Higher insulin sensitivity enables carnitine to burn more fat as omega-3 fatty acids elevates the metabolic rate.”

Simultaneously, by increasing l-carnitine levels more long chain fatty acids can be transported for energy production. This increases fat burning and reduces fat storage. At the same time the body is more energised and this translates into more motivation and stamina to support lasting weight loss.

No need for carb loading

When combining omega-3s with l-carnitine there is no need for carb loading. For a long-time there has been a firmly held view that loading the body with carbohydrates prior to exercising will help to enhance carnitine fat-burning activity. Although studies have proven that this does work1, 2, it is not necessarily the healthiest approach to weight loss.

Increasing omega-3 levels together with carnitine can achieve similar results, but with better overall health benefits. One study has shown that this combination can increase energy levels and reduce triglycerides and free fatty acids3. Not only does this improve weight loss results, it also improves cholesterol levels for better cardiovascular health.

Elevating carnitine and omega-3 fatty acid concentrations

l-carnitine and omega-3 for weight lossEating a diet rich in lean pasture-raised red meats, dairy products, nuts, seeds, collard greens, broccoli, bananas, and whole grains helps to elevate l-carnitine concentrations.

The best natural source of omega-3 fatty acids comes from fish with a high fat content, such as salmon, sardine and tuna. Other food sources include eggs, walnuts, flaxseeds, cauliflower, mustard seeds, and Brussels sprouts.

There are plenty of supplements available that contain l-carnitine and/or omega-3 fatty acids. These can help accentuate weight loss during exercise regimes. Always consult with a doctor before taking supplements to ensure suitability. Follow the recommended dosage unless otherwise directed by a health professional.


L-carnitine can help to accelerate weight loss. However, it must be accompanied by insulin to be effective. Improving the availability of omega-3 fatty acids can help to mobilise insulin and elevate metabolism to support the fat burning actions of carnitine. This is an excellent example of a synergistic combination of nutrients with several positive health benefits.
