Recently I tried PQQ (10mg) + ubiquinol (50mg). It was too much, I had heart palpitations. I tested PQQ only. After 1 week, today, I do not take phenylalanine/Korean ginseng anymore. I have a better, smooth, not too high, level of energy. I re-ordered 4 bottles of PQQ, I want to give it to my mother (she has weak thyroid and surrenals as well) Pay attention, the first 3 days, I had the weird feeling that my legs and my arms were flooded by electricity. And coffee made it worst. Please note that when I started PQQ, I was taken other supplements: ashwaghanda, rhodiola, American ginseng, Korean ginseng, maca + vit C + acetyl-l-carnitine + iron + phenylalanine + glutamine + pregnenolone (I have hormonal imbalances) Excuse-me for the possible mistakes, english is not my mother language.
PQQ - 10 mg is too much

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.

I take these in combination with other pills but I have noticed that my memory has gotten so much better. I think these are working!
Good little energy booster

I've needed a little less sleep with PQQ over time, definitely notice less fatigue in my day too. It's a little pricey for me to take all the time but worth a try at least once.
