PQQ for Athletes: My Mitochondrial Biogenesis Reversal

Okay, confession time: I used to roll my eyes at PQQ supplements. Back when I was competing in triathlons, everyone was chasing the next exotic compound, and pyrroloquinoline quinone felt like just another buzzword. I'd tell my athletes, "Focus on your basics—protein timing, electrolyte balance, sleep—before you mess with mitochondrial biogenesis."

Then I actually read the research. And not just the marketing abstracts—the full studies. A 2023 systematic review in Nutrients (doi: 10.3390/nu15081923) analyzed 11 human trials and found something I couldn't ignore: PQQ supplementation at 20 mg/day for 8-12 weeks consistently improved mitochondrial function markers by 27-42% compared to placebo (p<0.01 across studies).

So I tested it on myself during a heavy training block. And... well, I'm writing this article now, aren't I?

Quick Facts: PQQ for Athletic Performance

What the Research Actually Shows

Here's where it gets interesting—and where I had to change my mind. The mitochondrial biogenesis mechanism isn't just theoretical.

A 2020 randomized controlled trial (PMID: 31968348) had 40 healthy adults take 20 mg of PQQ daily for 12 weeks. The researchers measured something called PGC-1α expression—that's the master regulator of mitochondrial biogenesis. The PQQ group showed a 37% increase in PGC-1α activity compared to placebo (95% CI: 28-46%, p=0.002). More mitochondria means more cellular ATP production, which translates to... well, less fatigue during your third workout of the day.

But here's what really convinced me: the crossover with athletic performance. A Japanese study published in Journal of the International Society of Sports Nutrition (2021;18(1):45) had 24 trained cyclists take 20 mg PQQ daily for 8 weeks. They didn't just measure blood markers—they did actual performance testing. Time to exhaustion at 80% VO₂ max increased by 12.3% in the PQQ group versus 3.1% in placebo (p=0.01). That's not marginal—that's potentially race-winning.

Now, I need to be honest about limitations. The sample sizes in these studies are small (n=20-40 typically), and most are industry-funded. But the mechanistic data is solid, and my clinical experience with about two dozen athletes over the past year aligns with the findings.

PQQ vs CoQ10: Which Should You Take?

This question comes up constantly. They're different—and honestly, you might benefit from both.

CoQ10 (ubiquinol) is an electron carrier in the mitochondrial respiratory chain. It helps existing mitochondria work better. PQQ stimulates the creation of new mitochondria. Think of it this way: CoQ10 is like tuning up your car's engine; PQQ is like adding more cylinders.

Dr. Bruce Ames' work on the triage theory of aging suggests that both compounds address different aspects of mitochondrial decline. In practice, I've had CrossFit competitors report better recovery with the combination—especially those over 35 who are dealing with age-related mitochondrial efficiency drops.

A 2022 pilot study (doi: 10.3389/fnut.2022.987234) actually tested the combination in 60 adults with fatigue. The PQQ+CoQ10 group showed significantly greater improvements in energy scores than either supplement alone (p=0.03). Sample size was modest, but it's promising.

Dosing, Timing & What I Actually Recommend

Look, I've experimented with this myself—different doses, different timing. Here's what works:

Dose: 10-20 mg daily. I start most athletes at 10 mg. The 20 mg dose has more research behind it, but 10 mg seems effective for maintenance. There's no established upper limit, but I wouldn't exceed 40 mg without medical supervision.

Form: BioPQQ® is the patented form used in most studies. I usually recommend Jarrow Formulas' PQQ (they use BioPQQ®) or Life Extension's PQQ. Both are third-party tested.

Timing: Morning with food. PQQ is fat-soluble, so take it with a meal containing some fat. I tried it pre-workout—didn't notice acute effects. This isn't a stimulant; it's a structural nutrient that works over weeks.

Stacking: If you're going to combine with CoQ10, take both in the morning. Some evidence suggests they're synergistic. I've had marathoners take PQQ with omega-3s (also support mitochondrial membranes) with good results.

One of my clients—a 42-year-old ultrarunner—started 10 mg PQQ daily during his 100-mile training block. After 10 weeks, he reported: "Not faster, but the late-race energy crashes disappeared." That's exactly what mitochondrial biogenesis should do: improve energy substrate utilization when glycogen runs low.

Who Should Avoid PQQ?

It's generally safe, but:

Pregnant/breastfeeding women: No safety data. Skip it.

People on blood thinners: Theoretical interaction (PQQ may have mild antiplatelet effects). Check with your doctor.

Those with mitochondrial disorders: Paradoxically, stimulating biogenesis might stress already-dysfunctional mitochondria. Medical supervision required.

Honestly, most healthy athletes: Probably fine. But if you're under 25 with great recovery? You might not need this yet. Mitochondrial density naturally declines with age—that's when supplementation makes the most sense.

FAQs

How long until I feel effects? Most studies show measurable changes at 8 weeks. Don't expect overnight energy—this is structural change at the cellular level.

Can I take PQQ with stimulant pre-workouts? Technically yes, but... why? PQQ isn't acute. If you're relying on stimulants for energy, fix your sleep and nutrition first. This drives me crazy—the stim-junkie culture in sports supplements.

Is PQQ better than NAD+ boosters? Different mechanisms. NAD+ supports mitochondrial function via sirtuin activation; PQQ creates new mitochondria. Some evidence they're complementary, but the research on NAD+ precursors in athletes is thinner.

Will it help with muscle growth? Indirectly maybe—better recovery might allow more training volume. But it's not an anabolic agent. If muscle growth is your goal, prioritize protein and creatine first.

Bottom Line

So yeah—I was wrong about PQQ. Not completely wrong—it's still not a substitute for sleep, protein, and periodization. But for athletes pushing volume or dealing with age-related energy declines? It's one of the few "advanced" supplements that actually has mechanistic plausibility and decent human data.

I've got a 50-year-old CrossFit Games masters competitor on it now. After 12 weeks, her repeat sprint recovery improved by 15%. She said, "I feel like I have my 30-year-old mitochondria back."

That's the goal, isn't it?
