I've been type 2 diabetic for 12 years now and with some new medications I'm on, plus my constant lack of appetite, I just recently started buying these. I bought these small tubes for $1.00 at my walmart and I must say, these grape ones taste like candy. Almost like they're grape flavored smarties giant size. Very worth buying. Not chalky tasting at all. I keep a vial in my purse, on my night stand, in my bookbag for day trips.
