I take severral supplements from Stop Aging Now, including Vitamin D, Astaxanthin, and Magnesium 360. THEY ARE ALL IMPORTANT, but CUR-Q10 Ultra is one of the most important. I take two tablets every day, one with Breakfast and one with Dinner. Of coourse, a healthy diet is also important, and I usually have Blueberries, Walnuts, and Non Fat Greek Yogurt for breakfast. But I ATTRIBUTE MY EXCELLENT HEALTH AT AGE 86 TO THE FACT THAT YEARS AGO i DISCOVERED STOP AGING NOW, AND STARTED USING CUR-Q10 ULTRA.
