Benefits
Maltodextrin: the benchmark glycogen replenishment carbohydrate in sports:
Maltodextrin is a glucose polysaccharide obtained by controlled partial hydrolysis of corn starch (or other cereals), resulting in a mixture of glucose oligosaccharides with varying degrees of polymerisation (DE — Dextrose Equivalent — typically between 5 and 20 for sports maltodextrin). Maltodextrin is the most widely used carbohydrate in sports supplementation and functional foods due to a unique combination of properties: very high water solubility (unlike native starch), neutral or slightly sweet taste (unlike glucose/dextrose which has a very sweet taste), low to moderate osmolality (unlike pure glucose/sucrose, which have very high osmolality and can cause gastrointestinal discomfort in high doses), and intermediate intestinal absorption rate (faster than native starch but slower than free glucose, which provides a moderate insulin peak instead of the sharp peak of dextrose).
High Glycemic Index with lower osmolality than simple sugars: the ideal combination for glycogen replenishment:
Despite being a polysaccharide, maltodextrin has a very high Glycemic Index (GI) (GI ~85 to 105, comparable to or higher than pure glucose with GI = 100) — because the short glucose chains are hydrolysed very rapidly by intestinal alpha-amylases, resulting in glucose release into the blood almost as fast as free glucose. However, maltodextrin has a much lower osmolality than glucose and sucrose in equivalent aqueous solution — because each osmotically active maltodextrin molecule contains multiple glucose units (unlike pure glucose where each molecule is an individual osmotic unit). This lower osmolality means that concentrated maltodextrin solutions (which provide large amounts of carbohydrates) are much less irritating to the gastrointestinal mucosa than equivalent glucose solutions — explaining why maltodextrin is tolerated in much larger doses (40 to 80g/serving) than pure glucose (>30g/serving often causes osmotic diarrhoea).
Rapid energy supply pre and intra-workout:
As a pre-workout supplement, maltodextrin taken 30 to 60 minutes before exercise provides glucose for muscle and liver glycogen stores and for the bloodstream, ensuring immediate available energy substrate for the start of training — especially important for morning workouts or fasted workouts (more than 4 hours after the last meal). As an intra-workout supplement in long-duration sessions (>60 to 90 minutes), maltodextrin provides continuous energy to maintain blood glucose levels and delay muscle glycogen depletion — the main factor of fatigue in prolonged endurance training.
Post-workout glycogen replenishment: the carbohydrate anabolic window:
In the immediate post-workout period (first 30 to 60 minutes), the rate of muscle glycogen resynthesis is maximal — GLUT4 transporters are maximally expressed on the myocyte membrane by the exercise itself (regardless of insulin) and glycogen synthase is maximally activated. Maltodextrin, with its high GI and rapid glucose availability, is the most efficient substrate for glycogen replenishment in this window. For maximum glycogen replenishment, maltodextrin can be combined with fast-absorbing protein (whey) in a 3:1 to 4:1 ratio (carbohydrates:protein) — the combined insulin response from maltodextrin + protein maximises glycogen synthesis and amino acid uptake by the muscle simultaneously.
Versatility of use: the basis of homemade mass gainers:
One of the most popular uses of maltodextrin in sports nutrition is the preparation of homemade mass gainer shakes — mixing maltodextrin with whey protein, rolled oats, peanut butter, or other caloric ingredients to create a personalised gainer with macronutrients and calories controlled by the athlete, without the fillers, colourings, and sweeteners of commercial mass gainers. This approach is preferred by bodybuilders and strength athletes who want total control over the composition of their mass gainer.
100% corn maltodextrin, no additives: maximum purity and versatility:
The product contains only 100% corn maltodextrin without any additives, excipients, sweeteners, colourings, or flavourings — which gives it a neutral taste and maximum mixing versatility. It can be added to any protein shake, fruit smoothie, juice, or water without significantly altering the taste or texture of the base drink. It is the "blank carbohydrate" to add to existing sports nutrition.
Uses
Recommended dosage: Mix 0.5 to 1g per kg of body weight (35 to 70g for a 70kg athlete) in 350ml of water or other beverage. Consume before, during, or after training as per energy needs. For intra-workout use in long sessions, prepare a solution of 30 to 40g in 500 to 750ml of water with a pinch of salt (electrolyte). For post-workout combination with protein, mix 60g of maltodextrin with 30g of whey for a 2:1 carbohydrate:protein ratio. 500g = 14 servings of 35g.
