Why is everybody so excited about Super Greens? What are Super Greens, and just why are they so super? If you're like me, you've probably occasionally strayed into the supplement aisle (aisles) of a Whole Foods store or the like, and seen endless bottles and boxes and tubs of all sorts of enigmatic and obscure supplements. A whole bunch of them fall under the 'Super Greens' label, and include such suspicious sounding substances like 'Spirulina' or 'Chlorella'. Green powders, basically, and people claim they can work miracles. Others sound pretty mundane, like 'Wheat Grass' or 'Wild Barley', and are common additives to smoothies and shakes. So why are they so popular with people who seem to be in the know?
