Natural Power ISO Fit Review
ISO Fit is a product from Austrian based company Natural Power. The product description stats that this product is designed for athletes in pre competition or in competition to avoid muscle cramps and power loss. This review will aim to understand how these ingredients can achieve these claims.
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.
Sodium chloride is otherwise known as salt. It is theorised that sodium chloride can help prevent cramps as the key mechanism in muscle contraction is the flooding of the action potential in the muscle membrane, and so if there is a sodium deficiency it may cause the muscle to cramp (1).
Magnesium gluconate 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.
Calcium lactate has been found to treat and prevent calcium deficiencies as it helps aid bone formation and density. Research has not found this substance to be effective, (2), however more studies are needed to determine this.
Ascorbic acid (vitamin C)
Vitamin C is known to be a powerful antioxidant (3). 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 (4), however the only proven function of vitamin C is the prevention of scurvy (5).
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 (6) as well as a reduction in fasting triglycerides (7). An increase in fasting insulin has been found due to a decrease in insulin sensitivity (8). Further research is needed for this supplement in order to understand the mechanisms.
DL-alpha-tocopherol acetate 50% (vitamin E)
Dl-alpha tocopheryl acetate is otherwise known as vitamin E and is an antioxidant (9). This means that it protects the muscles from free radicals, which causes muscle soreness and damage to the muscle tissue and fat cells (10). Dl-alpha tocopheryl acetate can counteract these free radicals before damaging these parts of the body which can allow exercise to be prolonged (11).
Calcium D-pantothenate (pantothenic acid)
Calcium D-pantothenate (pantothenic acid) is otherwise known as vitamin B5 and is water soluble. This ingredient helps keep a healthy digestive tract (12) and uses vitamin B2 (13). Pantothenic acid has pantethine which has been found to lower cholesterol (14).
Pyridoxine hydrochloride (Vitamin B6)
The active form of vitamin B6 is known as P-L-P (15), which is stimulated by exercise (16). 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 (17).
Riboflavin (Vitamin B2)
Riboflavin is a nutrient that has been found to help in fat metabolism via the electron-transport chain (18) and an antioxidant (19). 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 (20).
Thiamine Mononitrate (Vitamin B1)
Thiamine is also known as vitamin B1 (21) is an essential role in carbohydrate metabolism and oxidation (22). The reported effect that have been found includes, a decrease in heart rate, blood glucose and lactate concentrations (23).
Folic acid is also known as folate is a water soluble mineral that, along with other nutrients is necessary for red blood cell production (24). It can also help regulate nitric oxide levels in the blood (25).
Biotin can also be know as vitamin B7 or Vitamin H. it has been found that it can contribute to metabolism and cell development (26) as well as providing energy during exercise (27).
Cyanocobalamin 0.1% (vitamin B12)
Research studies on vitamin B12 have found that it is required for red blood cell production (28), Protein synthesis and the repair and maintenance of tissue cells. (29).
Calcium citrate is used as a preservative, a food additive that enhances the flavour and regulates acidity.
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.
Calcium carbonate is used as an acidity regulator, anticaking agent, stabiliser or colour.
Maltodextrin is a polysaccharide which is a complex carbohydrate. This ingredient is water soluble and unlike other carbohydrates, is easily digestible (30) and can give a quick release of energy without any spikes of glycaemia (31).
Zinc gluconate is used to help aid in the growth and development of body tissue (32) as well as a variety of biological processes including wound healing and muscle cramps (33). Zinc supplementation has also been found to improve muscle strength and endurance (34)
Ferric pyrophosphate is a water – insoluble iron compound which is used to fortify ingredients (35).
The main function of citric acid is the reduction of physical fatigue (36). The reason for this is due to citric acid being a major component of the tricarboxylic acid (TCA) cycle. TCA cycle is the process of converting carbohydrates, fats and proteins into carbon dioxide and water (37). By increasing citric acid it activates the TCA cycle and in turn speeds up ATP production thus replenishing energy.
Natural pineapple aroma
Natural pineapple aroma is used to enhance the flavour of the product.
Acesulfame K 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.
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.
Riboflavin is a nutrient that has been found to help in fat metabolism via the electron-transport chain (38) and an antioxidant (39). 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 (40).
