Natural Power Weight Manager Review
Weight Manager is a product from Austrian based company Natural Power. The description of this product states that it has important nutrients designed for weight loss whilst supporting physical vitality and efficacy when dieting. this review will aim to understand if/how these ingredients can achieve this.
Dextrose is a fast absorbing carbohydrate that gives a quick release of energy. It is usually found in supplements as its properties mix very well with other substances.
Cocoa powder has been found to include flavonoids which are antioxidants, they can aid in the oxidation of LDL, (1,2) and augments the antioxidant defense system (3). Cocoa powder has also been found to stimulate nitric oxide production which can reduce oxidative stress and reduce the risk of heart attack (4).
Maltodextrin is a polysaccharide which is a complex carbohydrate. This ingredient is water soluble and unlike other carbohydrates, is easily digestible (5) and can give a quick release of energy without any spikes of glycaemia (6).
Whole milk powder/Soy protein isolate/ Milk protein hydrolyzate/ egg white powder
Whole milk powder, soy, milk protein and egg white powder helps aid muscle protein synthesis when combined with resistance training (7, 8). Other key features include increasing muscle mass (9), an increase in lean body mass (10, 15) and greater recovery from exercise (11). Longer periods of supplementation have shown greater gains in fat free mass (12).
The reason for greater recovery of exercise can be due to a post exercise insulin response (13, 14, 16) which means glycogen resynthesis occurs rapidly so exercise can be prolonged, with greater training volume increased hypertrophy and decreased muscle damage.
Vegetable oil can be used in many diets, one of the main uses of this product is that it can raise LDL cholesterol and lower HDL cholesterol and lipoproteins (17).
Guar gum is a dietary fibre that has been reported to decrease plasma cholesterol concentration (18) and increased satiety (19). However a meta-analysis found that although this product is safe no benefit has been found compared to a placebo (20).
Artificial chocolate flavour
Artificial chocolate flavour gives the product the chocolate flavour.
Sodium saccharin is a sweetener that is calorie free. This ingredient is used in many products and is used to make the product taste sweeter and does not have any nutritional benefit.
Vitamin and mineral blend
