I've only recently received my mixed box of collagen bars. I don't have a favourite, because they all taste delicious. I am 77 (so I've been around for a while) and go to the gym twice a week, walk my dog 7 days a week rain, hail or shine. I've tasted a lot of different 'health' bars in my time and finally gave up buying them all together because they never did the job and tasted disgusting. When I saw the ingredients in Raised bars I decided that I would give them a try. So glad I did, and I would happily recommend them to anyone. Keep up the good work and keeping it real.
