What are the Benefits of Maltodextrin?  

Fitness fans – this is what you came here for. The main benefit of maltodextrin is it’s use as a great source of energy when you need it – we’re talking high calories and fast. So, when you’re working on explosive power, or hitting the drop sets and you feel your levels plummeting towards the end, supplements and sports drinks containing maltodextrin have got you covered.  

Maltodextrin is a rapidly digestible sugar. It provides you with 4 calories per gram and because it is so readily absorbed into your system, it gives a quick energy boost, which is particularly beneficial to bodybuilders and weight lifters in general. When your energy levels plummet, maltodextrin helps you recover for that extra-hard set.  

Maltodextrin can also be used for improved endurance, enabling you to keep going during a longer cardio workout or HIIT session.  

Another key benefit of maltodextrin is the way it will help you recover from high intensity exercise.   

 

Dosage  

To help you recover for your next training session, and train at a high level again, it is important to replenish your depleted glycogen stores. The faster you can replenish your glycogen, the quicker the recovery.   

To maximise glycogen replenishment rates after high intensity exercise lasting longer than 90 minutes, it recommended that you consume 1-1.2g/kg/hr of high GI carbohydrates (e.g. maltodextrin) in the first 4 hours of recovery.  

Whether you need to follow this recommendation will depend on the intensity and duration of your exercise session and how long you have to recover before your next session.  

  

What are the Dangers of Maltodextrin?  

The main risk with maltodextrin is also linked to its benefit: the ability to give you a lot of sugar – fast! Maltodextrin has a high glycaemic index (GI), which means that it can cause a spike in your blood sugar. It’s safe to consume in very small amounts but always consult a GP if you have any concerns. 

For anyone on a low-carb diet, maltodextrin would need to be considered as part of your daily carb intake. 

There is also evidence to suggest that maltodextrin consumption may affect the composition of your gut bacteria. An unhealthy gut can cause a number of problems so this is another thing to keep in mind when taking maltodextrin.

 

Maltodextrin vs. Dextrose  

Maltodextrin and dextrose are both carbohydrate supplements that come in powder form. You’ll find both supplements in shakes that are geared to build mass and aid in recovery.

While they share many properties in common, dextrose is the simpler form of sugar of the two. Your body doesn’t need to break it down as much as maltodextrin for energy – maltodextrin features a string of glucose molecules, which can be easily broken down, but not quite as quickly as dextrose.
