PQQ - 10 mg is too much

7 people found the following review helpful

Posted by Reviewer2882806 on Dec 28, 2014

I use 2.5 mg (1/4 capsule) of PQQ once a day for certain health problems. Life Extension PQQ capsules are currently made large enough to divide into smaller doses - I use 3 oz paper dixie cups. I tried Jarrow PQQ, but the capsules were too small to divide. 10 mg of PQQ daily gave me insomnia and a facial rash. You would never get 10 mg of PQQ in a healthy diet. Too much PQQ is obviously not natural, so I only use the lowest possible dose.

After taking this supplement for one week, I can tell the difference in my workouts. I have more energy, I feel stronger and less fatigued after workout. I will keep taking as long as I can afford buying it. Thanks Iherb for the hands down fastest shipper on the net :-).
