not so good

I have CFS/ME and tried it for mitochondrial support. It did boost my energy but made me jittery like caffeine does. It also caused heart palpitations so I stopped using it after 3 weeks.

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.

These truly are life extending and will take these the rest of my life and in combination with all the other supplements I take I have more energy with these and a quicker recovery time after my daily 5 miles of jogging and walking each day and I am 68 and just keep going and going all day and half the evening now. Really an excellent supplement

Some very impressive studies on this new super-nutrient. Been using it for a couple of weeks now -- still experimenting but can say I do feel a difference in my energy levels and my workout performance.
