If you’re asking, it’s because IMHO it is the best digesting, most stable carb powder I’ve found for intraworkout use besides cyclic dextrin, which is also faster but costs substantially more. And I can still digest & utilize large amounts well, like up to 75g intra without issue (I don’t get to have a meal before many morning sessions, just a Rice Krispies bar).
So Karbolyn for me outperforms dextrose, maltodextrin, fructose, carb10/pea starch, waxy maize/corn starch, Vitargo (blend of some of those), oat powder, sweet potato powder, and so on.
It’s made of pulverized potato, corn & rice. The flavors taste good, the unflavored goes well with anything, not too thick and works in fairly small or large amounts of water.
Cyclic Dextrin is king, but I don’t need that as often so I buy less of it. It offers more rapid & specific/acute blood sugar control.
