My first contact with StemEnhance® was in 2006 when a Canadian friend recommended it to me. Because it was sold in a MLM framework, I resisted trying it until 2008 when the same friend happened to be in the Seattle area and again brought it to my attention. During a recent winter flooding in my basement, I had fallen on both of my arthritic knees a couple months before that and one knee was still painful. I was finding long walks -- my preferred form of physical exercise -- impossible due to the discomfort. Literally after taking the recommended dose of StemEnhance® for two days. I was again able to walk my usual 2.5 miles near Lake Washington in nearby Seward Park. Also I find I have a different increased sense of well-being. Visually I am seeing clearer and my eye doctors confirm that. I highly recommend StemEnhance®, StemFlo™, and StemSport® as well as StemPets® and StemEquine® (now available in chewable form) for your pets. Thanks for visiting my website!
