Ultimate Nutrition CLA - 90 softgels is a supplement containing Conjugated Linoleic acid, which is a naturally occurring essential fatty acid. It is obtained only from eating foods that are rich in it, as the body cannot produce its own supply of this fatty acid. CLA is popular as an effective weight loss and muscle-building product, which people use to improve the shape of their body. Like other types of oils, CLA is fully absorbed and utilized by the body after digestion. Studies have demonstrated that this fatty acid can inhibit lipoprotein lipase, an enzyme which is responsible for breaking down fats from our diet, leading to their absorption and storage in the body. By stopping the action of this enzyme, CLA helps decrease the amount of fat stored in the body, especially when coupled with regular exercise and a healthy diet.
