Conjugated Linoleic Acid (CLA) is one of the few supplements on the market today that advertise fat loss and have legitimate scientific backing to legitimate. CLA is an omega-6 polyunsaturated essential fatty acid aimed at the breakdown of fat in fat cells to free the fatty acids into the blood stream.
Fatty acids successfully break down the fat from the fat cells which will reduce the total amount of fat in your body. Subsequently, the ratio of fat-free to fat mass in your body will go up as well. CLA also has proven qualities that increase fatty acid oxidation from fat stored in the skeletal muscle and fat cells. It essentially starves the fat cell and keeps the fat cells small and from getting any bigger. Fatty acid oxidation is the breakdown of fat cells that are then used for energy for the body. Therefore, the more fat cells that are oxidized, the less fat that is in your body. CLA also reduces resting metabolic rates in the body which helps your body deal with fat more efficiently and keeps the heart healthy!
Dosage of CLA widely varies anywhere from one gram to seven grams a day. Most experts and research sites have different opinions on what dosage works best. It really comes down to individual sensitivity and what works best for you. From anecdotal research and personal experience, I have concluded that the optimal dosing level hovers anywhere from three to five grams daily. Anything lower than three will not be enough to make a discernible difference, and anything over five can be too much over time for certain body types.
In addition, you will need to take the product for four to six weeks to begin to notice any lasting effects as a saturation point has to be reached in the body for the effects to take full effect.
