I drink water and get my carbs from things like a fresh garden salad.
I'm so confident that no such product is worthwhile that I haven't bothered to look into any of them at all, never tried them, don't want to.
So I guess I'm responding just in case you or any other readers are open to the idea that these things are pointless. They just make money for some company and do us no good whatsoever. They're pricey, they are marketed with words like "convenient" and "great tasting", they come from factories.
I could be wrong, but I would be very surprised to discover that I am.
