Dextrose vs Maltodextrin

[ThePolishHammer]

Whats the diffrence between the two?
What is each used for?
are they the same thing?

 

[MuscleDm]

Dextrose is a monosaccharide with a very high GI rating. Maltodextrin is a polysaccharide with a very high GI rating, this is because of the amylose to amylopectin ratio. Either/or will do a great job of replenishing muscle glycogen post training.

Both have a GI of 100.

Dextrose is higher on the GI (Glycemic Index) list than Maltodextrin, however, Maltodextrin is higher on the Insulin Index. For a better explanation, I've taken this from one of Mr. Nobody's posts, over at AF.net

GI in ascending order; Maltose elevates blood sugar the most:
Lactose
Honey
High fructose corn syrup
Glucose
Glucose tablets
Maltodextrin
Maltose


Then there is this to think about:

insulin response to different foods

not the same as glycemic index:
read:
The popular glycemic index is a measure of the speed at which carbohydrates enter the blood after a meal. A high-glycemic index means that blood sugar rises rapidly in response to a meal while a low-glycemic index means that blood sugar rises very slowly. Traditionally, nutritionists thought that the faster the carbs got into the blood, the bigger the insulin response. So in an attempt to manage insulin, they recommended always eating low-glycemic foods.

However, several studies since have shown that some low glycemic index foods have huge insulin responses! So the correlation between glycemic index and insulin response breaks down with some foods. For example, milk products have a very low glycemic index. But they promote insulin responses parallel to the highest glycemic foods. What's the deal? Well, it appears that there are several other factors that determine insulin release besides carb content and the rate of carb absorption.

This is why the insulin index was generated. This index actually measures insulin response to a food. So rather than assuming insulin response is correlated with carb absorption, these researchers decided to go ahead and measure it. And their results were eye opening!

Bodybuilding and Athletic Supplementation Description
Dextrose gained its popularity in the bodybuilding community for basically one reason, creatine monohydrate. Dextrose is the premiere ingredient in the so-called "Performance Creatine's". Why? Dextrose is equal to maltodextrin on the glycemic index having a score of 100. Which means that when you take dextrose at the same time with creatine its intake into the muscle is far greater than taking creatine alone. Dextrose or any high glycemic carb causes insulin levels to go up rapidly, thus bringing more creatine into the muscle cells. Bingo, high performance creatine.

Whats the difference between Maltodextrin and Dextrose?
1. TASTE, maltodextrin has an extremely weak sweetness to it. Plus it doesn't mix as well as dextrose. Dextrose on the other hand is very sweet and DISAPPEARS in water when stirred with a spoon. Hence, it is very friendly to the user. Adding dextrose to creatine makes it taste good and mix easily. Both are derived from corn strach which gives them their high glycemic level rating. But maltodextrin is complex and dextrose is simple.

maltodextrins are polymers of dextrose

maltodextrin’s glycemic index should be considered metabolically equivalent to glucose (dextrose).

The filler used is commonly maltodextrin, dextrose, or corn syrup solids, all made from manipulating the starch contained in corn. These additives are all carbohydrates and must be counted. In fact, all three of these fillers have the same glycemic index as does glucose.

THEMACHINE...that was VERY well defined and very informative. I was wondering the same things and you clarified that SIMPLY and UNDERSTANDABLY. thank you. Never done the karma thing but am starting now

Dextrose has alot more calories also, I use about 50 post workout wtih whey and creatine.

 

[ThePolishHammer]

So post workout, dextrose is slightly better for creating a mass building insulin spike?

Actually, maltodextrin and dextrose have almost identical calories; maltodextrin has about 368 cal/100 grams; dextrose has about 366 cal/100 grams.

You may be getting a higher calorie content due to volume differences (i.e. you are taking in a higer volume of dextrose in the same size of serving due to the difference in weight between the two). If you measure them equally though, they are almost the exact same calorically.

I don't know for sure -- they are probably pretty comparable as they both have the same GI. Dextrose is sweeter and mixes better. You'd probably be fine with either.

 

[muskate]

dextrose is a simple sugar. maltodextrin is a polysaccharide comprised of glucose molecules. They are both very similar and have similar GI ratings and insulin release. You can use them interchangeably.

The best carbohydrate powder in my opinion is waxy maize. It's a high molecular weight carbohydrate. What that means is it shuttles what you take with it into muscle cells. It's great to take post workout with a high quality whey protein.

I use isolation from n2bm.com and waxy maize after each workout.

Maltodextrin isn't very sweet so it's a lousy choice since you;ll need more to get the same flavor as dextrose or sucrose.
