Scientific Description
Dextrose is derived from corn starch, (very similar to maltodextrin) and is used in several manufacturing applications for several reasons. It is produced by the enzyme conversion of corn starch and refined by ion-exchange demineralization. Dextrose is a fine white powder, hygroscopic and dissolves in water instantly (disappears).
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.
What is 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.
Recommended Usage
Take dextrose after you workout out, when glycogen levels are low. Approximately 50 to 100 grams. Using creatine with dextrose is an excellant anabolic agent.
