Protein World Premium CLA Review

CLA Powder is a product from UK based company Protein World. The supplement is a naturally occurring fatty acid and this review is will aim to understand what this supplement can achieve.



Conjugated Linoleic Acid (CLA) has been shown to have weight loss properties (1); there are several reasons for this which includes an increase in energy metabolism (2), insulin resistance (3), stimulation of lipolysis, which is due to an impaired signalling which reduces triglyceride synthesis and releases free fatty acid which normally occurs when energy demand rises (4). Other mechanisms include a suppression of appetite (5), induced adipocyte apoptosis which decreases body fat mass and increased energy expenditure (6).

Gelatine (capsule)

Gelatine is a protein which is made from amino acids glycine and proline. The suggested benefits of gelatin have been to boost metabolism and increase satiety, however there is insufficient evidence to reinforce these claims.


Glycerin is a thick colourless, odourless liquid which has been suggested to be a hyper hydrating agent (7). The main reason for this is that it can increase blood osmolality which augments the retention of water (8). It has been suggested to lower heart rate and prolonged exercise (9), however research is still sparse on this ingredient further studies are needed in order to fully understand the capabilities of glycerin.

Purified Water

Water is water and can hydrate.
