Matrix Nutrition Night Shredder Review

Matrix Night Shredder is from UK based company The description of this product states that it is a non stimulant with fat burning properties and has sleep promoting properties. This review will aim to examine the ingredients to understand this product can achieve this.


Raspberry Ketone

Raspberry Ketone is derived from the chemical of red raspberries. It has been found to prevent and reduce obesity and fatty liver (1). This is due to raspberry ketone altering lipid metabolism by stimulating lipolysis and fatty acid oxidation (2) and reducing fat mass in adipocytes (3).


L-Carnitine is a dipeptide made from the essential amino acids lysine and methionine. L-Carnitine plays an important role in fat metabolism by allowing long chained fatty acids to pass through the mitochondrial membrane (4, 5).

Irvingia Gabonensis

Irvingia Gabonensis is a water soluble dietary fibre (6). It has been found to delay stomach emptying which leads to the gradual absorption of dietary sugar (7). The lowering of cholesterol has also been found to be a key component of this ingredient by binding to bile acids (8).


Conjugated Linoleic Acid (CLA) has been shown to have weight loss properties (9); there are several reasons for this which includes an increase in energy metabolism (10), insulin resistance (11), 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 (12). Other mechanisms include a suppression of appetite (13), induced adipocyte apoptosis which decreases body fat mass and increased energy expenditure (14).


Magnesium has been found to be used for 300 biochemical reactions in the body (15). It has been found to maintain muscle function (16), supports a healthy immune system (17), keeps the heart beat steady (18), and helps strengthen bones (19). It has also been found to maintain blood glucose levels (20) and aid in the production of energy and protein.


Theanine is an amino acid that is found in green tea. Green tea supplementation has been shown to have several health properties including an increase in plasma antioxidant which will lead to a lowering of oxidative damage (21, 22), decreased blood pressure (23, 24) and it can protect against coronary atherosclerosis (25). Other health effects that green tea can have includes a lowering of cholesterol, an increase of insulin activity (26) and a regulation of blood glucose levels which can help reduce body fat.


5-HTP has been known to produce significant effects on food intake in obese populations; research has found that this is done by increasing serotonin which will help avoid food craving, post meal satiety and reduction of pre meal appetite. (27)


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 (28). The main reason for this is that it can increase blood osmolality which augments the retention of water (29). It has been suggested to lower heart rate and prolong exercise (30), however research is still sparse on this ingredient further studies are needed in order to fully understand the capabilities of glycerin.
