I have a quick question about my post workout shake. I know Dextrose is thrown around as a good supp to put in their whey shake, but should I bother if i get my carbs through blended food in my shake? My post-workout shake is usually 2 scoops of whey, I glass of 100% fruit juice, 1 banana, a half a cup of frozen fruit and a cup of yogurt...doesn't this cover all my post carb needs? Any thoughts would be great, thanks!
