Health Thru Nutrition PQQ 20mg 120 Servings Pyrroloquinoline Quinone as PureQQ | Promotes Mitochondrial Biogenesis | Certified Vegan | Non-GMO Gluten Soy Free Capsules| Clean Label PQQ Supplement

This product is very potent and effective. And it did not cause any sleep problems which I was a little worried about because 20 mg is a higher dose. I’m very satisfied.

Looks like a well made product.

Effective supplement at reasonable price.

It seems to work, though I would have expected a little more. Mental clarity enhanced to a degree.

It is a very good product and the dosage and quantity per bottle allows me to take more per day at the same price as the lower dosage.

I took a chance on this, having read a brief article about how PQQ is what the mitochondria need to perform at their best. The mitochondria are called the powerhouse of the body's cells, and when ramped up, they deliver the energy to run the body efficiently. PQQ appears to be the nutrient that is needed and is often in short supply, especially among the elderly. I am elderly and was disappointed to note how little energy I could find to do the things I wanted to do.So I bought a bottle of PQQ and shared it with my wife — 60 caps divided by the 2 of us = a one month trial. Honestly, at the end of the month I hadn't noticed anything, so I didn't reorder. but a week or two later I thought that perhaps a one month trial wasn't a fair trial, so I ordered a second bottle. Within a week I began to find the energy to get at some of the home projects that had languished sometimes for years. I now regularly tackle physical tasks that have been waiting for me to get around to it. I can't prove the PQQ is the reason, but it seems likely. It might be one of those mind-over-matter things or a kind of placebo effect, but no matter, my life has improved, my satisfaction with it anyway.My wife thinks it has perhaps helped her a bit, which is not such a resounding report, but that just reminds me that everybody's body is different, and what works for one may work differently for another.It's not fearfully expensive and I'd gladly recommend that you try it and give it time to kick in, but keep my wife's experience in mind too.

I bought these to help improve energy and help my mitochondria to power up.. I have been taking them for 2 months and even with my B12 and as I’m still crashing in the afternoon.. I guess they work at different levels for different people.

Seem fine so far but too early to tell if it working
