I like the convenience of powders. I put them in smoothies. I can't taste the kale so that's good. I like this company's powder products and their prices and healthy ingredients. I can't tell if they're helping me or not, for sure, but don't notice any negative effects, and my smoothies energize me, though I put a bunch of other stuff in them, too, like collagen powder, liquid multi, uti herbal, blueberries, etc. This is an easy way to get kale. If I buy fresh kale, it ends up spoiling before I get around to eating it.
