Vega Health Optimizer (Vanilla Chai) as a gift last month from Robert Cheeke, I'm officially hooked on it. I've since grown to love the Chocolate and Berry flavors, and the Whole Food Vibrancy Bars. I'm not a huge fan of sport drinks though.
I use the Whole Food Health Optimizer as a meal replacement, usually for breakfast. I feel very full and satisfied after drinking it. Sometimes I'll just have it as a snack or a treat, or to curb a sugar craving. Though I can't say they're filling, the Vibrancy Bars are great snacks - I love the buckwheat crunch. The Sports drinks are OK - they remind me of a vitamin drink or Red Bull in taste, but apparently they're great if you need some extra energy (I drink them fast because I don't like the flavor)

Building Muscle on a plant-based Diet). Vega is used by many athletes as a protein supplement, pre and post workout drink, and energy boost. Bredan Brazier, a vegan triathlete, developed the formula to assist with his training - you can read the full story here.
I've met Brendan a few times through Robert and he's a great guy - really mellow and modest. Both Brendan and Robert have books out right now - Thrive and Vegan Bodybuilding and Fitness.
