Question:
What is PQQ? Does it help with aging and memory? Is it similar to CoQ10?

Answer:
Both PQQ (Pyrroloquinoline quinone) and CoQ10 (ubiquinone) are antioxidant compounds used by the body, but they differ in many ways and, unlike CoQ10, which has been extensively researched in well-controlled clinical studies, only a few, small and relatively short clinical studies have been conducted with PQQ.

I used to get debilitating headaches within half hour after taking this supplement (20 mg). The headaches stopped after I stopped taking it. I'm considering trying a lower dose: 10 mg or lower if I can find it.

Please review some PQQ products that contain also Ubiquinol!

This has a high PQQ and Ubiquinol to Price ratio:

Jarrow Formulas, Ubiquinol, QH+ PQQ, 30 Softgels or 60 Softgels.

At least if you look at iherb prices

I also am interested in knowing test results of Ubiquinol +PQQ from Jarrow. I’ve read that Ubiquinol is much better absorbed than Ubiquinone, especially as one ages, but don’t know how valid that assertion is.

Thank you for your suggestion Angelika. Please see this CL Answer about the difference between CoQ10 and ubiquinol, and more about their absorption: https://www.consumerlab.com/answers/what-is-the-difference-between-coq10-and-ubiquinol/coq10_ubiquinol_difference/

I am extremely fond of all the advice, accuracy and sound information found on this highly rated website. Please keep us all apprised and once again Thanks!!!

Thanks for the article. Perhaps this particular quinone will upstage CoQ10 (ubiquinone)? It seems possible, judging from the many studies on PQQ linked on PubMed, where researchers are stating that PQQ is known to enhance mitochondrial function. I keep hearing about how mitochondrial function figures prominently in our health, whether the issue is metabolic disturbance, heart disease, dementia or cancer. I greatly look forward to Consumer Lab's test of PQQ supplements! I am eager to purchase some, but I always like to consult your database first. Thanks!

Have no financial interests in this or any other competing product(s). Have been taking P.Q.Q. for one month. Perhaps it's a placebo effect that explains the following comment, but I'm 65 years old and I've been ... introduced ... to mild "brain fog." I do believe this supplement has helped me in terms of better concentration. Feel less distracted. Once again, my report is strictly anecdotal, but for now, I'm staying with this product. I'll report (positively or negatively) if and when any changes occur.

Alan11348 -- My husband's brain scan shows amyloid plaques and he is receiving two rx Alzheimer drugs that have only short term effect in slowing the process. He's 72 and quite highly functioning but the senior moments -- hard recalling names of people and places instantly although the data show up after 20-30 minutes, etc. -- are present.

Anything further to report after six months on PQQ?
