Here is a very complete article on PQQ I found:
Pyrroloquinoline quinone - Scientific Review on Usage, Dosage, Side Effects | Examine.com
It might be an alternative to take this separately, instead of mixed with the same vitamins as in your other, product.
You can get Jarrow brand at Amazon... this is a very well known quality manufacturer.
Amazon.com: Jarrow Formulas Pyrroloquinoline Quinone, Supports Heart and Cognitive Function, 2 mg, 3 Caps: Health & Personal Care
From what I have read so far, PQQ has to be taken for a while to see any benefits. There is however little human study done on it.
