I just found another website with info on Maca Root and they sell the product for less than I've seen it anywhere else. I paid only $29.95 for a kilogram. They also sell capsules for $14.99, but like many other sources, they recommend using it as a food and getting the powder instead. You certainly save money doing it that way. I don't know how many capsules I'd need to make up a teaspoon. That's what I take every day mixed in a shake with low carb whey protein and DaVinci syrup.
It does add a few carbs to the total, but I'm inclined to think it's worth it. Maca root is a vegetable, and I eat other vegetables with carbs. I prefer to pick and choose the ones that give the most benefit. Potatoes, for example, are worthless but garlic is not, even though it's high in carbs, and a little garlic goes a long way.
The product at this website http://macaweb.com
is certified and each shipment is analyzed for quality. Interesting in the testimonials page there was an entry by someone who was diabetic and hypothyroid who had profound improvement in his lifestyle and was able to lower his thyroid medication much to the surprise of his doctors. Usually, I don't put much stock in testimonials, but they don't mention thyroid in most of the promotional material on Maca Root. You have to hunt for it. A big problem with most botanicals is that no one is willing to pay for a big expensive study to see what they do because you can't patent it, so it's highly unlikely that you'll recover the cost of your study.
Since this product is perfectly safe, I decided the best way is to try it and see what it does. I've been taking Maca root for about a month now and I like the way it makes me feel: more energetic, mentally sharper, and I don't get cold. I think it's a little early to say much more than that.
