I haven’t noticed a significant impact on my blood sugar or ketone levels after drinking MUD\\WTR, but everybody reacts slightly differently to foods. For example, I heard from one of my followers on Instagram that drinking MUD\\WTR kicked her out of ketosis.  I think that most people will not see an impact, even if they follow a ketogenic diet, because one serving of MUD\\WTR has only three grams of net carbs.
