As the name suggests, non-thermogenic fat burners are mostly stimulant-free.

This quality makes them an ideal and effective alternative for those who are sensitive to stimulants, but you can also combine them with thermogenic products, or use them between cycles to aid your weight management efforts.

Non-thermogenic fat burners generally contain ingredients that can:

  1. Assist your body to release stored body fat
  2. Reduce fat deposits in cells
  3. Help transport fatty acids into cells to increase energy metabolism and efficiency.

Two effective and popular non-thermogenic fat burners include L-carnitine and conjugated linoleic acid (CLA).


Fats are burned for energy inside muscle cells at structures called the mitochondria but can’t pass efficiently through the mitochondrial membrane without sufficient L-carnitine.

Therefore, the amount of fat you can conceivably burn is related to your L-carnitine levels. Research also shows that L-carnitine supplements can increase the use of fat as an energy source, which may assist with weight management.

Scientific evidence supports L-carnitine’s efficacy at:

  • Supporting fat metabolism for energy by mobilising fatty acids from fat cells.
  • Promoting increased energy, stamina and enhanced exercise endurance.
  • Optimising metabolic processes.

Conjugated Linoleic Acid

CLA is a fatty acid naturally present in meat such as beef and lamb, as well as in various dairy products. Modern-day diets and food processing practices can reduce the amount of CLA we consume, which suggests that we could benefit from supplementing with this omega-6 polyunsaturated fatty acid.

CLA supplements that provide a free fatty acid mixture high in isomers such as cis-9, trans-11 and trans-10, cis-12 help to mobilise stored fat so that the body can more easily burn it for energy.

CLA may also prevent fat accumulation by inhibiting enzyme action related to the fat storage process, which can improve body composition and toning.

Quality CLA supplements use advanced lipid technology to create convenient, easy-to-swallow soft gel capsules that enable precise CLA intakes at predetermined time intervals. Research shows that CLA supplements can reduce body fat, increase muscle tone and improve health.

Better together

Based on the individual benefits of each product, combining CLA and L-carnitine can be an effective supplement strategy for weight management and body conditioning.

CLA diverts fatty acids to muscle cells and, once there, L-carnitine can improve the efficiency with which these fatty acids are transported into the mitochondria of the cell, where they are metabolised for energy.
