Grüns Comprehensive Daily Nutrition ($59, originally $79)
"I carry packets of Grüns and give them out like candy to family and friends. They're delicious enough that you'll look forward to having them (no chalkiness or bitterness you have to choke down like some green products), but more importantly, they pack vitamins, minerals, prebiotics, and whole-food ingredients into a daily ritual. Who doesn't want the gift of health and a little treat-yourself practice?" — Angelica Marden, publisher
