Real people. Real fog. Real relief.

What people just like you
are saying.

From the third period to hour eight of back-to-back meetings — real feedback from people who used Headstrong to think clearly again.

★★★★★

"By the third period my legs were fine but my head wasn't. I could feel myself half a step slow on reads I'd normally make without thinking. Headstrong is the first thing that actually fixed that, not just masked it with caffeine."

"I'm not an athlete, I run a 12-person team and my fog hits at 2pm like clockwork. I used to just push through it foggy. A few weeks on Headstrong and that afternoon crash basically disappeared. No jitters, no crash later."

Priya D. — Product LeadBay Area tech · Verified buyer
★★★★★

"Training hard and working a demanding job at the same time was wrecking my focus by the end of most days. I didn't expect a supplement built around dosing I could actually verify but the NSF cert is what got me to try it, and the fog relief is what kept me on it."

Understand the enemy

Brain fog isn't in your head. It's in your brain chemistry.

That heavy, slow, can't-quite-focus feeling has real physiological drivers: chronically elevated cortisol from training or work stress, oxidative stress building up in neural tissue after sustained exertion, dopamine and norepinephrine running low after hours of demand, and a brain energy system that starts running short on fuel when you push it for long enough. It's not a willpower problem. It's a supply problem. Nothing on the market was built to address the actual causes — until Headstrong.

✕Coffee and energy drinks spike you, then drop you into a worse fog than before
✕Recovery stacks cover protein, hydration, sleep — never the cortisol and oxidative load actually driving the fog
✕No other formula is NSF Certified and built specifically to clear and prevent brain fog

Sports nutrition brands with an NSF Certified, brain-fog-specific formula — before Headstrong
Every other brand treats mental fatigue as an afterthought — one token nootropic bolted onto a protein or creatine base, never at a clinical dose, never independently verified, never addressing what's actually causing the fog.
The dose comparison

Full clinical doses. Sub-clinical doses don't clear brain fog.

Most brands include a fraction of the studied dose so they can list an ingredient on the label. That's not enough to actually move the needle on brain fog. Every ingredient in Headstrong is dosed at or above the level used in the research it's based on.

Why Headstrong exists

Built by a scientist who studies fatigue.
Demanded by an athlete who lived it.

Headstrong was not invented in a boardroom. It was built because one professional athlete lived brain fog from the inside — and a PhD sports scientist had spent two decades studying exactly why it happens.

Co-Founder  ·  Chief Science Officer
Dr. Darren Burke
PhD, Sport & Exercise Science

Darren spent two decades in elite sports nutrition research, studying how the brain holds up — or doesn't — under sustained physical and mental load, and testing products for the biggest brands in the world. He kept seeing the same gap: everyone was formulating for the body under fatigue and nobody was formulating for the brain under fatigue. He previously founded and scaled a sports nutrition company from zero to category leader.

"Fog isn't in your head. It's a chemistry problem. So we built a chemistry solution."
Co-Founder  ·  Active Professional Hockey Player
Evan Nause
Professional Hockey Player  ·  Co-Founder

Evan did not build Headstrong because it was a good business idea. As an active professional hockey player, he lived the fog firsthand — brain fog that didn't clear, mental fatigue that outlasted physical recovery, focus that wasn't there when he needed it late in a game. Nothing on the market addressed it, so he built the product himself.

"I knew exactly what I was feeling. So we built the product that didn't exist."
The only brain-fog-first formula

Every quick fix stops at the spike. We stop the fog at the source.

Sports nutrition has spent 40 years optimizing the body. Protein for muscle. Creatine for power output. All of it matters. None of it addresses the organ that decides whether you're still sharp in the fourth quarter or the fourth meeting of the day.

Why brain fog happens — and how Headstrong ends it

Five ingredients.
Each one targets a different cause of brain fog.

Brain fog isn't one thing — it's the result of several systems running short at once. No proprietary blends, no underdosed fillers. Every ingredient at its clinically-studied dose, independently verified by NSF Certified for Sport.

i
Creatine Monohydrate

Your brain runs on ATP just like your muscles do. Under sustained physical or mental exertion, the brain's rapid-energy reserves (phosphocreatine) run low — and that energy shortfall is one of the most direct drivers of the slow, heavy feeling of brain fog. A full 5g clinical dose keeps that energy system topped up.

5g Dose
ii
Lion's Mane Mushroom

Studied for its support of Nerve Growth Factor (NGF), which is tied to neuron health and everyday cognitive clarity. It's the ingredient working to keep the "haze" from setting in as mental fatigue accumulates over the day.

Brain Hero
iii
Ashwagandha KSM-66®

Chronically elevated cortisol — from training stress, poor sleep, or a demanding schedule — is one of the most common root causes of "I can't think straight" days. KSM-66 is clinically studied to help lower cortisol, addressing fog at the hormonal level instead of just powering through it.

KSM-66®
iv
NAC — N-Acetyl Cysteine

Precursor to glutathione, the body's primary antioxidant. Intense physical or cognitive exertion generates oxidative stress in neural tissue, which is linked to the mental sluggishness of brain fog. NAC helps clear that oxidative load and build resilience against it recurring.

NAC
v
L-Tyrosine

Precursor to dopamine and norepinephrine — the two neurotransmitters that deplete first under sustained stress or fatigue, and the ones directly responsible for that "can't focus" feeling. L-Tyrosine replenishes the raw material for both, so focus holds instead of collapsing under load.

The standard that actually means something.

Most professional leagues and NCAA programs require it. If you compete — and especially if you get tested — this is the standard that protects you. And if you're not an athlete, it's still the fastest way to know a brand's dosing claims are real, not marketing.

Questions answered

What people ask about brain fog.

A mix of factors: elevated cortisol from stress or training load, oxidative stress in neural tissue after sustained exertion, depleted dopamine and norepinephrine, and a brain energy (ATP) system running short after hours of demand. Headstrong's five ingredients are each chosen to target one of these directly.

That's exactly the scenario Headstrong is built for. Because it works on the underlying causes of fog rather than a caffeine spike, most people find the 2–3pm slump gets noticeably shorter and shallower within a few weeks.

Neither. It's a daily formula with five ingredients at full clinical doses — no caffeine, no stimulant spike. It's built to reduce the causes of brain fog over time, not to make you feel wired for an hour.

No stimulants. No caffeine. Nothing that spikes and crashes. You can take it any time of day without disrupting sleep.

Headstrong is NSF Certified for Sport, which means every batch is independently tested against the full WADA prohibited substance list. No banned substances, no surprises.

Yes. Brain fog from training and brain fog from a demanding job come from overlapping causes — cortisol, oxidative stress, and depleted focus chemicals. The formula was developed with elite athletes but the underlying science applies to anyone under sustained mental or physical load.

Most people notice improvements in focus and afternoon energy within two to four weeks of daily use, as the ingredients build up and address the underlying causes rather than delivering a one-time spike.

Your first tub ships immediately, billed $39.99 monthly. Skip, pause or cancel any time before the next billing date — no fees, no phone call.
