Well, I will say I was my own experiment, did a lot of research and then bit the bullet. This product is fantastic!!! Within 2-3 weeks I started noticing the difference. I have thyroid issues (plus other issues at 51) But I tell you, this made me feel 'lifted'. I feel energized and younger, so much healthier than what I have in years. I just mix it into a wee amount of water and down the hatch. Now Im being honest here, what it smells like (grass) is what it tastes like, but its over n done with and for the benefits you receive its a no-brainer. You get used to it quickly and we just need to put our big pants on and get the job done because the pay off is terrific. 2 final words...'Do it'!
