NSF Certified for Sport
Your brain is about 2% of your body weight and uses about 20% of its energy. Sports nutrition spent forty years on the rest. Every Headstrong formula is built for that 2%. Raichle & Gusnard, PNAS, 2002
No single ingredient is the star.
Most brands start with an ingredient and look for a benefit. We start with the job, then build a lineup where every ingredient plays a role. Like a good team, the formula is designed around how the parts work together.
Same clock.
Different arenas.

Julia Gosling
Olympic silver medalist in 2026. Scored the first goal in Seattle Torrent history.
“What I do after the game matters as much as the game itself. SLEEP is part of every night for me.”
SLEEPIn her routine
Zack Bolduc

“After a night game my head is still going. SLEEP is how I shut it down and recover.”
SLEEP
Sophie Shirley
Boston Fleet
“I take SLEEP before bed on the road. It's how I'm ready to go again the next morning.”

SLEEPThe roster
From every arena.
“I stay locked in through the last rep instead of fading. No jittery crash afterward, and it's NSF Certified so I don't have to think twice about what's in it.”
“Between classes and late study sessions I needed something I could take daily. Steady focus in the afternoons, no jitters, no 3pm wall.”
“A friend at work said his son was taking it, so I tried it. I'm hooked. I've had the best sleep scores in a very long time.”

Questions, answered.
Ask us anythingWhat's the difference between PROTECT and FOCUS?
PROTECT is the daily foundation: stimulant-free, taken every morning, the way you'd take a multivitamin. FOCUS is for a moment, like a game, a pitch or an exam, and it does contain a stimulant. Most people take PROTECT daily and add FOCUS when they need it.
Can I take all three?
Yes. The Daily Brain Stack is built for it: PROTECT at the start of your day, FOCUS when it counts, SLEEP before bed. Each has one job, and together they cover a full day.
Are they NSF Certified for Sport?
Yes. Every Headstrong formula is NSF Certified for Sport, tested for banned substances and label accuracy.
Why no hero ingredient?
Because each formula is built around a job, not an ingredient. The benefit comes from how the ingredients work together, and every dose is printed on the label.
