Maltodextrin is apolysaccharide, astarchy complex carbohydratemade up of a chain of glucose molecules. It is similar in composition to glycogen. Despite beingformed ofglucose molecules, it’s not sweet. It also triggers an insulin spike, so it can get to the muscles fast. Unlike some polysaccharides, the molecular bonds between glucose molecules aren’t strong.So you can break it down and metabolise italmost as fast as pure glucose. All these factors combine to make maltodextrin the carbohydrate of choice for energy drinks. Our energy, hydration and recovery ranges include everything you need to push the boundaries of performance. From protein powder to handy tablets and energy bars for when you’re on the go, you can find them all in our sports nutrition sale. Whether you’re training for your next marathon or just need that nutritional boost, SiS is here to help. EXPLORE OUR OTHER PRODUCTS
My closest friends have been mountain bike enthusiasts for as long as I’ve known them.I’ve never caught the bug in the same way until recently. There are different types of sugars, depending on their formulation. Glucose is theform used by the body, also referred to as blood sugar, andsold as a supplement called Dextrose. Fructose is the form found in fruit. Then you have sucrose, a disaccharide, made up of a glucose and a fructose molecule bound together. Sucrose is what we know as white table sugar. There are other disaccharides such as lactose,found in milk,and maltose,found in malt and beer. These other formsaren’t as relevant to exercise. The three sugars above are the important ones for this discussion.Hypotonic drinks (the lowest concentrations)replace fluids lost through sweating without replacing much carbohydrate. These can be useful for low-intensity exercise. You might think ‘just drink water’, but there is a risk to drinking too much water without replacing salt and sugar. You’d have to drink a lot of water for this to become a problem, but the potential is there and hypotonic drinks are the solution. Boost your training with Science in Sport, a top-tier sports nutrition brand. Discover our high-quality products, supported by science and loved by world-class endurance athletes. Elevate your performance with natural, carb-rich energy gels and more. SiS gels are highly beneficial as part of your fuelling strategy without the liquid volume that can leave you feeling bloated and sluggish. Our complete product range has been developed using a world-class approach to banned substance testing, providing assurance for athletes. The ‘Team Sky Bundle’ (while it’s half price). This consists of 18 gels, 20 hydro tablets and 500g of rapid recovery powder.
Our complete product range is developed using a world-class approach to banned substance testing, providing assurance for athletes. Muscle glycogen can only be usedby muscles,whereas liver glycogencan be used for energy throughout the body. But, muscles can store up to 400g of glycogen, whereas the liver can only store up to 100g. REGO Rapid Recovery contains high quality protein with a complete amino acid profile enhanced by the addition of 2g of Leucine. A vitamin and mineral profile has also been included to support the recovery process by contributing to normal muscle function and protein synthesis There’s also a lot of conflicting evidence about consuming carbohydrate with protein post workout. One would think that the insulin spike from high-GI carbs like glucose and dextrose would allow for faster protein absorption. But some studies suggest it has no effect. It would also sound sensible to consume carbs as soon as possible after exercise to replenish glycogen stores. Again some studies show this isn’t essential in the same way as post-exercise protein. This is partlybecause your body will replenish those stores itself.
If you wanted to include fructose in your energy drink mix for longer rides, you could add sucrose (plain old white sugar) to a maltodextrin mix. This will give you all the fructose you need, along with a bit of glucose — so it’s a win-win. Out of all the SiS products, the energy bar contains the most fructose; because of the dried fruit pieces it contains. They also contain protein (good for muscle recovery) and fibre. Based on my research, these aren’t ideal during exercise. This is partly due to the fibre, which can be hard to digest and cause an upset stomach. Like the gels, they are a good way of getting large quantities of carbs in a small volume. I think if you wanted some variety from the gels during your ride, there are tons of energy bar recipes online that will be better.
So you can see that the majority of the contents is maltodextrin, with a much smaller percentage of fructose. SiS no doubt use fructose instead of glucose because of the benefits relating to the 60g/hour carb intake without it. This fits in with their alignment to top athletes, but it’s less critical for your average hobbyist. Using dextrose (glucose) instead of fructose would be more beneficial in all but the longest exercise sessions.

As with the carb discussion, I think the type of exercise you’re doing will dictate what ratio you need. SiS are aiming at pro athletes, so hypertonic ratios could be beneficial forsustained, high-intensity exercise. For most of us, isotonic ratios should be more than enough for all but the most strenuous exercise.
