If you are over 40 and never heard of Maca, it's worth 10 minutes of your life to look up maca's health benefits. Lab rat tests for "red maca" suggests it can possibly help shrink the size of prostate in men, and help women with PMS and menopause symptoms, and much more.
My personal experience is it gives you great energy and vibrancy. After years of tinkering, I have used a Maca product called MaCafe, a powdered coffee substitute, and with my additions, I simply love it, and I'll never go back to coffee. It gives a "smooth" energy boost as opposed to that "jerky" caffiene jolt that can keep me awake occasionally at night.
My standard recipe is a half teaspoon or so of MaCafe powder, will vary from person to person depending on taste of course, added to hot water, then add a teabag of Tazo Organic Apple Red. I tried many different flavor teas but this one works best for me. I have this awesome blend of spices consisting of Cacao Chocolate powder, nutmeg, cinnamon, and real vanilla powder when I can find it. The other things I add are the standard things added to coffee, either and organic half and half cream (I am still evolving to grass fed dairy), or coconut milk, although I am trying to stay away from using canned products because of the linings of cans. So far as sweeteners, my article on coffee addresses the sweeteners I use, which can vary, but basically I use Sweet Leaf Stevia, Ultimate Sweetener Birch Xylitol (no aftertaste like stevia), or real raw honey. An important note is that the MaCafe is roasted and the enzymes and nutrients that give maca its wide array of health benefits are no longer there I think, so to really get the benefits of maca, you should use the raw maca in smoothies or sprinkled on cereal or elsewhere. It has the most amazing sweet nutty smell that will tell you it is something special and begs you to "try me". I buy my raw smoothie maca here which is red maca. But before I get into red maca for prostate health, I got my regular (yellow) maca from this HIGHLY recommended online company called Imperial Gold. ~dw~
