  This 60+ Year Old Noticed A Difference In My Thinking Sharpness

  I tend to trust the Jarrow brand so decided to gave it a try. It does seem to make my thinking a little faster and sharper and I like that. Not dramatic. Just a little. A lot better than nothing. I'm over 60 and I can tell that compared to my 20's, 40's and even early 50's my thought processes and focus are not as sharp as they were. I was hoping for any improvement in this PQQ supplement. After 3 days I feel there has been a small but noticeable improvement. It feels like a bit of the often mentioned "brain fog" has been lifted or thinned out a little. For me this is not dramatic. I have noticed no negative side effects. I'm no biochemist or expert in how PQQ works or how to tell who it might work for I can only guess about that stuff. So, I'm guessing that being an "old fart" may mean I'm more likely to benefit from PQQ than someone younger whose brain may be operating closer to optimal already.

  like "Lucy in the candy factory"

  I am certainly not getting any younger. Being well into my 50's and working a nightshift for 7 twelve hours shifts in a row has taken a toll on my body and mind. Not complaining, its just the career path I chose. I work in a hospital lab and have to have my game on all night, like "Lucy in the candy factory". I read an article about PQQ and decided that I would like to try it. I have been taking CoQ10 and NAC on and off for years. I started taking the PQQ approx. a week ago and Wow, my physical stamina has increase quite a bit. I'm still a little worn out at the end of the shift but don't have to push myself to get all those end of shift duties done in a hurry. I'm more alert, memory is better, I'm 2 steps ahead of myself, more organized - its like I have a better rythmn as I work, like I used to when I was younger. I hope this lasts, I love this stuff and can't wait until my days off to see what I can get accomplished as switching over from nights to days is TOUGH. I am pretty non-productive for several days. I would not take this at any other time except when I wake up, I may not be able to go to sleep

  High quality supplement as usual for Jarrow

  PQQ is a supplement just becoming available the last couple of years; it is reported in research studies to improve the function of mitochondria in your cells and is even capable of stimulating mitochondrial biogenesis. It is reported to improve cognitive performance as well as physical endurance and performance under hard exercise. My own experience as an active 62 year old man confirms these claims in a relatively short time frame, much to my surprise. I do use ubiquinol CoQ10 also, which is recommended in combination with PQQ.I've been using CoQ10 for a long time, and would not say I notice any particular effects physically, but add PQQ to the equation and I was surprised at the results, which in a sense rules out Placebo effects. What I found was that in general I felt lighter on my feet and more agile just for every day physical motion, and my workouts show an improvement in stamina and strength.Gauging the mental effects if any is a little tougher, as I had come off a period of intensive work and long hours just before the holiday break, but it seems to me I'm even more OCD and assiduous about being organized and responding rapidly and effectively to issues, so perhaps there is benefit there, also. This is all after 3 weeks of use.There are many supplements which I think are of more benefit to older people, due to the decline in liver function with age and the body's lower effectiveness in synthesizing necessary nutrients and utilizing those which are consumed. I would recommend anyone 50 or over give this a try in combination with CoQ10 (ubiquinol variety). The more physically active, the greater the benefit may be.

  It works for my sleeping

  I am 51 years old female and I wake up twice at 1am and 3am every night . Then I took 20mg for daily for a week, it does not work and I cannot get significant change. Then I took 80 mg yesterday, I only wake up 4:30am this morning , I have taken Coq 10 for years and I have not felt any significant changes. It could reach equilibrium point.Since it cost $36 because of made in USA, I would give a try of another brand,even though I am a loyal fan for Jarrow. This is the first time write review for supplementary.
