My wife and I have been using New Earth products (formerly Cell Tech) since 1994. My wife received almost immediate results. I did not realize my results until I stopped using the products during a downturn in our financial income. Within weeks certain maladies returned, relief of which I had attributed to other remedies. I was persuaded to start the products again as an experiment. The immediate result was undeniable! I have since repeated the experiment just to prove to my skeptical ego it was indeed the nutrients and other healthful ingredients relieving my discomforts. We have continued to purchase and use the products faithfully.
