Maltodextrin: benefits, uses and consumption tips to optimize sports performance
Maltodextrin: Boost your athletic performance with this key carbohydrate. Energy, endurance, recovery, and practical tips for better training.

Nutrition plays a key role in preparing for and successfully completing every athletic challenge. Maltodextrin, a complex carbohydrate derived from starch, is now an essential ally for endurance athletes and athletes seeking performance. But what is it really used for? Why and how should you consume it before or during exercise? What precautions should you take? Find out everything you need to know to incorporate maltodextrin into your routine, boost your energy reserves, and achieve your goals.
What is maltodextrin?
Maltodextrin is a complex carbohydrate obtained by hydrolysis of starch, most often from corn, wheat or rice. Thanks to its chemical structure, it is quickly assimilated by the body while providing long-lasting energy, making it a central ingredient in the formulation of sports drinks and many dietary supplements dedicated to athletes.
The corn maltodextrin used by Impulse Nutrition has a high glycemic index, which allows for rapid release of glucose into the blood and efficient assimilation, even during exercise or recovery. This rapid assimilation power sets it apart from other sources of carbohydrates, while avoiding the excess of simple sugars that can cause sudden fatigue.
The technical specificities of maltodextrin
-Ultra-soluble powder form, easy to mix with water or other beverages
-Virtually free of fat and saturated fatty acids, therefore perfectly suited to high-quality sports nutrition
-Natural, additive-free bulking agent for readable and transparent formulas
The benefits of maltodextrin for athletes
Adopted by many endurance athletes and performance-seeking athletes, maltodextrin provides key benefits:
Immediate and lasting energy supply
Optimization of glycogen stores
Performance support during exercise
Improved recovery
Ease of use and assimilation
Its perfect solubility, neutral taste and easy digestion make it suitable for all profiles, even in cases of very intense physical activity.
Helps maintain concentration
What are the purposes for which maltodextrin can be consumed?
Maltodextrin has applications in many sporting contexts:
-Endurance sports (running, cycling, triathlon, trail, running, swimming, etc.) where the duration and intensity require a regular carbohydrate intake
-Weight training or crossfit sessions, to maintain energy during prolonged or split sessions
-Weight gain : during the weight gain phase, maltodextrin makes it easy to increase calorie intake without overloading the stomach.
-Rugby, team or combat sports, to support the effort during intense training or long competitions
-Daily food supplement for athletes with high energy needs, while ensuring that consumption matches actual expenditure
When and how should you consume maltodextrin? Before, during, or after exercise?
The use of maltodextrin is adapted to different key moments, depending on the objectives and specific needs of each athlete:
Before exercise: build up glycogen reserves
Consuming maltodextrin in the 3 days before an endurance event is a common practice among demanding athletes. This protocol, called "carbohydrate loading," aims to optimize muscle glycogen stores, allowing you to enter the competition with optimal energy reserves.
How to proceed?
-30 to 50g of maltodextrin per dose, diluted in 500 ml of water, 2 to 3 times a day in addition to a diet rich in complex carbohydrates (wholemeal pasta, rice, fruit, legumes)
-This strategy is particularly effective for endurance races, half marathons, marathons or trails
During exercise: maintaining performance
During prolonged physical activity, the body first uses stored carbohydrates (glycogen), then gradually switches to using fatty acids for energy when reserves are depleted. However, the priority use of fatty acids is often accompanied by a decrease in intensity and a feeling of fatigue.
Consuming maltodextrin during exercise allows:
-To prolong the availability of carbohydrates
-To avoid the “cravings” or the famous energy slump
-To support normal muscle function
Recommended dosage
-30 to 50g of maltodextrin per hour of effort, to be adapted according to the kg of weight and the physical intensity
-Mix in 500 to 750 ml of water for a fast-acting energy drink
Impulse Nutrition Tip: During exercise, remember to split your energy drink intake to avoid blood sugar spikes and promote constant energy.
After exercise: speed up recovery
Consuming maltodextrin during recovery promotes rapid replenishment of glycogen stores. Combined with protein and vitamin/mineral intake, it optimizes muscle repair and reduces the risk of post-exercise hypoglycemia.
In practice
-30 to 50g of maltodextrin in a post-workout drink, accompanied by a source of protein
-Ideal within 30 minutes of completing the activity
Focus on managing energy reserves before an endurance competition
Why increase your energy reserves before a competition?
Before a half marathon or marathon, the body must store as many complex carbohydrates as possible in the form of glycogen. This helps delay the transition to the fatty acid pathway, which, although necessary for very long efforts, remains less efficient than the use of carbohydrates for sustained effort.
Carbohydrate loading protocol:
| Day | Objective | Maltodextrin intake | Recommended diet |
|---|---|---|---|
| D-3 to D-1 | Increase glycogen stores | 30-50g, 2 to 3 times/day | Favor rice, pasta, fruit, legumes, avoid excess fat |
| D-Day (morning) | Maintain energy before the test | 30-50g, 1 to 2 hours before exercise | Breakfast rich in complex carbohydrates, low in saturated fat |
| During the race | Support the effort | 30-50g/h, split | High-carb energy drink |
Supplement the carbohydrate recharge with foods with a moderate glycemic index (rice, whole-wheat pasta) and fruits for stable energy.
Side effects and precautions to take
Well tolerated, but be careful with the dosage
Maltodextrin is well tolerated. However, if consumed in excess or too quickly, it can cause certain undesirable effects:
-Significant variations in blood sugar, especially in people who are sensitive or prone to metabolic disorders
-Digestive discomfort (bloating, intestinal problems), particularly in the event of an overdose or if the product is taken in too concentrated form
-Possibility of reactive hypoglycemia if the intake is not adapted to the energy requirement
Tips for limiting risks
-Respect the recommended dosages: 30 to 50g per hour of effort, depending on level and weight
-Split intake to avoid blood sugar spikes
-Test digestive tolerance during training, never on the day of a competition
