PQQ - 10 mg is too much
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.
I think these help me

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!

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.
I did not like it

The product did not suit to me but stimulated the frontal lobe of my brain in a way, which was very disturbing.

My Doctor put me me on this product and it seems to be helpful. I would suggest you ask your Doctor first rather than self 'guess' on any product you choose. My Doctor has recommended them all and I am very grateful. I am 81 and going strong.Thank you very much.
GOOD SUBSTANCE BUT A BIT COSTLY
Posted by Reviewer2283477 on Nov 28, 2011
lots of favourable research has been carried out with this vitamin like substance which is why I decided to purchase. It has potent neuro and cardio protective properties that are somewhat unique. I certainly dont feel any better (or worse) after one month however Im not entirely sure if one should "feel" anything from taking PQQ. I only wish it could be less costly. Hope this helps.

Have been taking one each morning for last few weeks and definitely beginning to notice that I have more energy - will keep taking them
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.
Helps on CFS symptom relief.
