In this review, I am going to cover a cell energy nootropic that is big in Japan: PQQ (Pyrroloquinoline quinone).
Just think of all the great things from Japan that become massive cultural trends in the West. Sushi! Ninja warrior! Iron Chef!
And now… PQQ? Maybe. PQQ is a prized nutritional supplement in Japan, where its purported anti-aging benefits include support for sharp mental clarity.
PQQ has a compelling back story and some off-the-charts antioxidant activity… but can it deliver enough nootropic benefits to live up to all its hype? Let’s check it out.
Let’s review PQQ in more detail.
How PQQ is Supposed to Work
In this review were talking about PQQ is a nootropic. But if we step back and look at the bigger picture, PQQ appears even more significant.
PQQ is important for cellular health. Okay, so maybe that sounds a little boring. But as it turns out, PQQ’s role in cellular health borders on the cosmic – literally.
Here’s the PQQ marketing story (and I am NOT sticking to it):
PQQ is reputedly present in Stardust.
We are talking literal Stardust here, i.e., interstellar particles.
Supposedly, at least according to the sci-fi marketing stories, PQQ carried to earth at the beginning of time played a role in the genesis of life itself on our planet.
Just imagine it: A comet streaking through the interstellar dust clouds, picking up some PQQ along the way, and streaking through the universe for millions and millions of years until getting sucked into the atmosphere of a newly formed planet Earth, breaking up and plunging into the primordial soup below.
Does it sound like BS?
Yeah, kinda. I think the PQQ-Stardust story is great, but is also likely greatly exaggerated.
But here’s the thing: PQQ is one of those life-promoting nutrient that sparks a number of different biological activities we need to survive. It is a cofactor for enzymes, a growth factor for newborns, and a key player in the bioenergetic processes that power all life forms. As a supplement, it is noted for helping immune function, cardiovascular health, nervous system health, and yes, cognitive function.
When it comes to cognitive function, one of PQQ’s many beneficial bioactivities has drawn the most attention:
Optimizing Mitochondria in Brain Cells
Mitochondria are the power plants that generate energy for all cells. But since the brain is such an energy intensive organ, mitochondrial function seems especially important for healthy cognition.
As we age, mitochondria may start to malfunction due to the damage accumulated from destructive free radicals over the course of years. Some research has suggested that damaged, misfiring mitochondria appear to be linked to cognitive decline, including neurodegeneration.
PQQ appears to help mitochondria in a few different ways:
Powerful Neuroprotective Antioxidant Activity
PQQ appears to be an incredibly potent antioxidant.
- In fact, it has been suggested to possess up to 5,000X the redox capacity (antioxidant potency) of vitamin C.
PQQ’s high antioxidant activity has been suggested in animal research to protect cells against oxidative stress while maintaining healthy mitochondrial function. It seems to suggest that protection extends to provide specialized support for the mitochondria.
Helps with Creation of Fresh New Mitochondria
In addition to protecting existing mitochondria, PQQ has been suggested to stimulate the biogenesis of fresh new mitochondria. Researchers have suggested that by sparking the creation of new mitochondria, PQQ multiplies its benefits, indirectly supporting longevity, cell energy efficiency, and resistance to free radical damage.
Stimulates Nerve Growth Factor Production
Additional research seems to attribute PQQ’s mitochondria-Genesis activity to act as a potent enhancer of nerve growth factor (NGF) production. Those same researchers suggested that PQQ esters may have potential to be developed into therapies for some neural problems in both the central and peripheral nervous system.
Fight Amyloid Plaques in the Brain
This potential PQQ benefit is hard to validate, but appears highly significant to brain health. Researchers have suggested that PQQ appears to inhibit the formation of amyloid proteins, dangerous irregular clusters and tangles that are strongly linked to onset of Alzheimer’s and other neurodegenerative problems. Researchers suggested that PQQ’s anti-amyloid activity has potential as a therapy in these cases.
Supplement makers claim that PQQ helps with long-range brain health. Some of them seem to place PQQ in an anti-aging category; for example, saying that cognitive health is just one extension of its overall whole-body anti aging benefits. Others will make performance-oriented claims that PQQ promotes mental energy, memory, and overall cognition. Still others will claim PQQ is some extraterrestrial life-sparking space-dust from Planet Queen.
If you ask me, PQQ is an intriguing nootropic that likely offers reliable support for healthy aging of the brain. In other words, to me it seems more of a brain health nutrient than a brain power-boosting nootropic. In theory, PQQ’s unique support for mitochondria might result in greater overall brain energy and enhanced brain cell energy efficiency. Whether or not this feels like an “energized brain“, I am not so sure… but some reviews do seem to reflect some mental energy effects.
Let’s see what the researchers have to say.
Researchers have Suggested that PQQ might:
Enhance “High-Level Cerebral Functions”
In this study, 71 volunteers aged 45 to 65 took PQQ 20 mg capsules, or 20 mg PQQ caps with co-Q10 300 mg, or a placebo daily for a span of 12 weeks. Throughout the study, subjects underwent a cognitive performance testing. At the study’s conclusion, researchers reported that PQQ supplementation brought significant enhancements to word memorization, attentional performance, and recall. Researchers also reported in improved some aspects of mental processing. PPQ seemed to work better when it was paired with the coenzyme Q10.
Improve Mental Energy and Mood
This study seems more than a little questionable, quality-wise, but here we go: 17 adult study subjects with sleep problems and fatigue took 20 mg of PQQ every day for a span of eight weeks. Throughout, the study subjects took questionnaires that covered several aspects related to quality of life, including mental performance. At the study’s end, researchers reported that PQQ supplementation seemed to improve quality of sleep, mood and emotional balance, and suggested PQQ may help with fatigue. The researchers tied these benefits to PQQ’s antioxidant and mitochondria-supportive benefits.
How to Take Pyrroloquinoline quinone (PQQ)
- Human research has used PQQ at a 20 mg dosage
- Retail PQQ supplements are typically 10 mg or 20 mg caps
- Keep in mind the limitations on human research for PQQ – because of this, it is impossible to determine what the “right” dosage is.
- Animal research supports PQQ’s safety; no surprise here as it is naturally present in ourselves anyway.
- BioPQQ is a fancy branded form of PQQ that is backed by a good deal of research
My Experience with PQQ
I have not taken PQQ as a standalone supplement. I believe in the bioactivities behind PQQ, especially as they relate to brain health. However, in my opinion, CoQ10 is a better option for me. Like PQQ, CoQ10 has unique energizing antioxidant activity, and seems to concentrate that activity in the mitochondria of cells.
- The big difference when it comes to CoQ10 vs. PQQ? CoQ10 is way more researched than PQQ, and usually cheaper to buy as a supplement.
Is PQQ a Good Nootropic?
I say yes. BUT, The Geek’s thumbs-up is tentative here. Perhaps the best way to say it, is that PQQ is loaded with potential. Its close connections to mitochondrial performance and sell health, especially in brain cells, seems to suggest an important role in overall brain health. The anti-amyloid research makes PQQ even more intriguing.
The animal research on PQQ is compelling, even exciting, and there’s a boatload of it (relatively speaking). But for some reason, human research lags way behind on supplemental PQQ. For that reason, I can’t get super excited about PQQ, but I do expect we’ll see some more positive brain research on it in the future.
Maybe then this Japanese import will be vaulted to prominence like the Iron Chef and Ninja Warrior that came before it.
