We're used to slurping down spinach in our green juices...but in sports drink powder? As if we needed another reason to guzzle down green stuff, Brendan Brazier and the Vega team come along and formulate Vega Sport, a beyond-healthy alternative to those sugar and chemical-filled drink mixes we see so often on the market. Popeye was onto something when he hopped on the spinach train - this veggie is actually a pretty lean, mean, green machine when it comes to your fitness.  It's an excellent source of iron, an essential mineral that carries oxygen to the blood and sustains energy for muscle-building, as well as flavinoid-filled for optimal cardiovascular health - so you're all set for the long run.
