So I'm over a year late seeing this post lol but I only found it just now after writing to Robek's myself. Has there been any confirmation or word from the company with a definitive answer on this topic since you all last posted? I wrote to them inquiring specifically about their protein powders and nutritional boosts which I know could very likely contain gluten ingredients. I'll post again when I hear back, but in the meantime, if anyone else has confirmation one way or the other, please post! Thanks!
