I’ve been using tart cherry juice concentrate in my bottles because I like the taste, not because of any particular alleged performance benefit. I’ll add maltodextrin and some fructose to get about 80 grams of carbs in a bottle.
I can’t find a definitive source that the sugar in TCJ is fructose. It makes sense that it would be, but I’m often surprised by what I don’t know. Can anyone confirm what type of sugar in in TCJ?
