Protein World Whey Protein Concentrate

Whey Protein Concentrate is a product from UK based company Protein World. The supplement claims that it can contribute to the growth and maintenance of muscle. This review will aim to examine the ingredients listed to see if it can achieve these claims.

Whey Protein Concentrate (Milk) (96%)

Whey protein helps aid muscle protein synthesis when combined with resistance training (1, 2). Other key features include increasing muscle mass (3), an increase in lean body mass (4) and greater recovery from exercise (5). Longer periods of supplementation have shown greater gains in fat free mass (6).

Muscle protein synthesis is increased due to high concentration of Leucine (BCAA) which is a signalling molecule needed to increase muscle protein synthesis (7). Consumption of whey protein helps increase muscle mass due to a greater amount of peripheral nitrogen retention whereas soy protein has been found to have a greater effect on splanchnic protein synthesis (8).

The reason for greater recovery of exercise can be due to a post exercise insulin response (9, 10) which means glycogen resynthesis occurs rapidly so exercise can be prolonged, with greater training volume increased hypertrophy and decreased muscle damage.

Sucralose

Sucralose 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.

The claim for this supplement was that it can help to contribute to the growth and maintenance of muscle. Based on the available research it is clear that the ingredients within this supplement can back up the claims of this supplement. It is recommended that this product be taken post workout. This product has no banned substances when referring to the WADA prohibited list when observing the label / ingredients posted on the website.
