Maltodextrin? Or Dextrose?- Which One???

[Texas Ranger]

I hate to sound like a broken record, but which one would you use in your post-workout drink? Maltodextrin? Or Dextrose? Or does it matter? Currently, I'm using 16 oz. of Grape Juice mixed with 2 scoops of Protein Powder with good results. i take one of these immediately after working out and another an hour later. Should I use Dextrose or Maltodextrin in place of the Grape Juice? What do you think?

Apparently the latest advice is to take a combo of maltodextrin and dextrose post-workout....with other added goodies like glutamine and creatine, etc., at your discretion - and of course protein...

I might replace your second shake with a bigger meal and comprise it of real food....

...bottom line of course are the results you see - so if grape juice is working for you - I don't see why you should switch to malto and dextrose....

Thanks bro! Anymore opinions?

even though maltodextrin has a high GI, it is still a glucose polymer so it is a complex carbohydrate. which means it is not going to digest as rapidly as the dextrose due to the slightly longer chain. for the purpose of insulin spiking dextrose is the best. a 50/50 combination in the post workout drink of 35 grams of each one does the job.

A combination of dextrose and malto works very well post workout.

The slower digestion of maltodextrins is only true when it is in a branched-chain. A straight-chain maltodextrin of fragmented amylose, will have a faster digrestion. BTW...GI refers to how fast a carbohydrate is digested and absorbed...therefore, in the case of the higher GI maltodextrin, it will digest quicker than dextrose. The faster a carbohydrate is absorbed through the small intestine, then the higher the blood glucose levels will be, and the more of an impact it will have on blood glucose levels.

Thank you for the info MR. BMJ...however straight-chain maltodextrins are not used in nutritional supplements used today. That comes straight from a personal friend of mine who engineered APM60 for Met Rx. 99% of the maltodextrins used today in nutritional supplments and sold in supplment stores are of the brainched chain variety.

So, dextrose would be the best bet, right?

Yes, the branched chain maltodextrins are commonly used by meal-replacement powders, which will help keep GI levels more stable. Duchaine was big on using these in his diet meal relacements. I thought we were specifically talking about the high GI maltodextrins for post-workout drinks though...lol. The branched chain malto's would negate the whole purpose of the post-workout sugar spike with their low GI's. The only reason I pointed it out was because most people don't know that their are different malto's out there which illicit different digestive effects. The uncertainty of which kind of maltodextrin a consumer may be getting is the main reason why I stray away from useing malto's as a post-workout drink...you never know what your getting. Besides, I think the differences between malto's and dextrose are pretty negligible in difference on their effects for insulin spikes. They're both gonna get 'em way up there. And...to make matter more interesting, this whole straight and branched chain differences go right out the window nowadays since the use of the newer specific engineered maltos (both straight and branched) actually can illicit whatever response the manufacturer wants to set them up for. Hey...take it easy, and nice meetin' ya!
