Peeroton Recovery Shake Review
Recovery shake is a product from Austrian based company Peeroton. This supplement claims that it is ideal to use post-workout and its ability to enable fast regeneration can promote an increase in performance. This review will aim to assess the ingredients in this supplement to see if it is capable of backing up these claims.
Maltodextrin is a polysaccharide which is a complex carbohydrate. This ingredient is water soluble and unlike other carbohydrates, is easily digestible (1) and can give a quick release of energy without any spikes of glycaemia (2).
Dextrose monohydrate 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.
Whey protein concentrate/ Milk protein concentrate
Whey and milk protein helps aid muscle protein synthesis when combined with resistance training (3, 4). Other key features include increasing muscle mass (5), an increase in lean body mass (6) and greater recovery from exercise (7). Longer periods of supplementation have shown greater gains in fat free mass (8).
Muscle protein synthesis is increased due to high concentration of Leucine (BCAA) which is a signalling molecule needed to increase muscle protein synthesis (9). 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 (10).
The reason for greater recovery of exercise can be due to a post exercise insulin response (11, 12) which means glycogen resynthesis occurs rapidly so exercise can be prolonged, with greater training volume increased hypertrophy and decreased muscle damage.
Cocoa powder has been found to include flavonoids which are antioxidants, they can aid in the oxidation of LDL, (13,14) and augments the antioxidant defense system (15). Cocoa powder has also been found to stimulate nitric oxide production which can reduce oxidative stress and reduce the risk of heart attack (16).
Latte Macchiato flavor (milk)
Latte Macchiato flavor provides no nutritional benefit and is included in supplements as a flavour enhancer.
Wheat protein hydrolyzate
Wheat protein hydrolyzate has been found to absorb more rapidly than free form amino acids and intact proteins (17), which can lead to a greater delivery to muscles and a greater post exercise muscle protein synthesis after exercise (17). It has been shown that wheat protein hydrolyzate can increase insulin response dramatically and is ideal for recovery post exercise (18).
Guar gum is a dietary fibre that has been reported to decrease plasma cholesterol concentration (19) and increased satiety (20). However a meta-analysis found that although this product is safe no benefit has been found compared to a placebo (21).
Magnesium stearate does not induce any nutritional benefits. The main reason for this substance being in the supplement is that it is a lubricant for the machinery that manufactures the product.
Sodium cyclamate 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.
Silicon Dioxide doesn’t add any nutritional benefits to this supplement. The main reason for silicon dioxide in this supplement is that it aids in the even distribution of the active ingredients in this supplement.
Zinc has been identified as a factor for many enzymes responsible for the synthesis, storage and release of insulin (22), with increases in lean body mass while fat mass either remains stable or decreases, depending on the degree of baseline zinc deficiency (23). With this evidence is has been shown that this ingredient is important for the growth and development of body tissues as well as this a variety of biological processes including wound healing and muscle cramps (24) have been found.
Ascorbic acid is known to be a powerful antioxidant (25). Studies have suggested that it can increase endothelial nitric oxide by protecting it from oxidation and increase synthesis, another function that Vitamin C has suggested includes reducing blood pressure (26), however the only proven function of vitamin C is the prevention of scurvy (27).
Ferrous sulphate is also known as iron sulphate, common uses for this ingredient are for people with iron deficiency. Iron levels have been found to decline due to exercise (28) with findings showing that it can help with fatigue (29).
Dl-alpha tocopheryl acetate
Dl-alpha tocopheryl acetate is otherwise known as vitamin E and is an antioxidant (30). This means that it protects the muscles from free radicals, which causes muscle soreness and damage to the muscle tissue and fat cells (31). Dl-alpha tocopheryl acetate can counteract these free radicals before damaging these parts of the body which can allow exercise to be prolonged (32).
Sweetener sodium saccharin
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.
Niacin is otherwise known as vitamin B3 and in an antioxidant. Research studies have shown that niacin supplementation increases growth hormones in response to anaerobic exercise (33) as well as a reduction in fasting triglycerides (34). An increase in fasting insulin has been found due to a decrease in insulin sensitivity (35). Further research is needed for this supplement in order to understand the mechanisms.
Cupric gluconate or copper gluconate as it is also called, has been suggested to contribute to the formation of red blood cells, healthy contribution to the growth and development of bones and organs as well as a participation in cholesterol and glucose metabolism (36). However although there has been evidence for this it is debated and others have found no change when administering copper gluconate compared to a placebo in healthy individuals (37, 38).
Calcium D-pantothenate (pantothenic acid) is otherwise known as vitamin B5 and is water soluble. This ingredient helps keep a healthy digestive tract (39) and uses vitamin B2 (40). Pantothenic acid has pantethine which has been found to lower cholesterol (41).
Pyridoxine hydrochloride is a form of Vitamin B6. The active form of vitamin B6 is known as P-L-P (42), which is stimulated by exercise (43). During exercise the body relies on the liver to produce glucose via glycogenolysis, for which vitamin b6 is essential for, and is an integral part of the glycogen phosphorylase enzyme and thus will provide energy to the bodies’ muscles (44).
Thiamine hydrochloride is also known as vitamin B1 (45) and is essential in carbohydrate metabolism and oxidation (46). The reported effect that have been found includes, a decrease in heart rate, blood glucose and lactate concentrations (47).
Riboflavin is a nutrient that has been found to help in fat metabolism via the electron-transport chain (48) and an antioxidant (49). It is also one of many nutrients that helps in the production of red blood cells. Levels of riboflavin has been found to diminish during exhaustive exercise (50).
Folic acid is also known as folate is a water soluble mineral that, along with other nutrients is necessary for red blood cell production (51). It can also help regulate nitric oxide levels in the blood (52).
Potassium iodide is known as a thyroid mineral (53) as it keeps iodine levels regulated in the thyroid (54). To date there is no research examining the effects of potassium iodide on athletic performance.
Biotin can also be know as vitamin B7 or Vitamin H. it has been found that it can contribute to metabolism and cell development (55) as well as providing energy during exercise (56).
Cyanocobalamin is also known as Vitamin B12. Research studies on vitamin B12 have found that it is required for red blood cell production (57), Protein synthesis and the repair and maintenance of tissue cells. (58).
This supplement’s vast number of ingredients can achieve the claims that it is a good recovery shake as it includes ingredients which help metabolise carbohydrates and fats as the vitamins to help protein synthesis, it also contains antioxidant properties. This product should be consumed post-workout. This supplement has no banned substances when referring to the WADA prohibited list when observing the label/ingredients posted on the website.
