I am 71 yrs old & I have always been DOG TIRED for over 10 years now! I have Chronic Anemia too - so that doesn't help. I researched CoQ10 for hours & hours - website after website. I also read all the reviews on AMAZON.com for ALL CoQ10 Products. I wasted so much money trying one Brand after another. Many of the CoQ10 Products I bought with additives nearly killed me because they made my "already HIGH BLOOD PRESSURE" SPIKE! I assumed the more "other ADDITIVES" the better it would be... NOPE! I was about to GIVE UP & just face the fact that CoQ10 doesn't WORK. But all the Great Reviews on AMAZON.com that I spent so much time reading about ON THIS PRODUCT HAUNTED ME. So I had to try it. This was "a lot pricier" than all the different CHEAP Brands I tried - but I GAVE ULTRA CoQ10 a try only because of the RAVING REVIEWS I read on AMAZON.com. But I really didn't want to spend this much money, especially IF IT WORKED. Well - in less than 2 weeks I KNEW IT WORKED. It perked me right up as long as I took it TWICE a day. I know within an hour when I forget my afternoon pill. I have been using it now faithfully for at least two years, maybe more. It is worth every Penny NOT to feel like I wanted to crawl in a hole & just die. This "ULTRA" HITS MY SYSTEM SO FAST. Within a half hour I am Bright Eyed & Bushy Tailed. It works even FASTER if I take it with my morning HOT Coffee or TEA. I have spent so much money on so many different Natural Homeopathic WORTHLESS ENERGY products over the years. Short of taking DRUGS, (LOL) I was just trying to find something that would take the EDGE OFF MY SLUGGISHNESS & that tired to the bone feeling that I would WAKE UP FEELING - ALL DAY - EVERY DAY of my miserable life. This is a MIRACLE PRODUCT for me not only because it WORKS, because it is SAFE & it doesn't Spike my Blood Pressure or give me "the Jitters." THANK YOU - THANK YOU - THANK YOU for this AMAZING PRODUCT! I now have a much better "Quality of Life.
