Absolutely love this and can attest to some of these add ins! No joke, since I started adding collagen, a little coconut oil, and raw honey to my coffee, I 1) no longer get the caffeine jitters, due to the protein content in the collagen and 2) my lower back pain has significantly reduced, almost to the point of being gone. (It only really bothers me if I've been at the computer for too long.) It's amazing and I never go a day without it now! I like Vital Proteins collagen and get raw honey from TJ's. I'll definitely have to try some of the spice combinations you recommend—they sound amazing!
