How Flykitt Is Eliminating Jet Lag and Redefining Human Performance
Few things kill performance like jet lag. Whether you’re a pro athlete flying across continents or an executive closing global deals, crossing time zones often means brain fog, poor recovery, and missed opportunities. But Andrew Herr, founder of Flykitt, believes he’s cracked the code — and the data backs it up.
The First Jet Lag Solution That Actually Works
In a study run with Inter Miami, Flykitt users saw a 94% reduction in travel-related symptoms during a brutal five-game, four-city trip around the world. According to Herr, “93% of people can fly anywhere in the world with minimal to no jet lag.”
What started as a typed-out Word doc with supplement timing, blue-light glasses, and circadian rhythm hacks is now a fully integrated system. Flykitt provides users with upgraded supplements, an adaptive AI-powered app, and real-time guidance that adjusts for flight delays, sleep patterns, and body type.
The Military Origins of Flykitt
Herr’s path into performance science wasn’t typical. With graduate degrees in immunology, health physics, and national security policy, he was recruited by the Secretary of Defense’s private think tank to study the future of human enhancement in warfare.
While advising the military, he began coaching high-level executives on the side. One asked for help managing jet lag during Asia business trips — where local negotiators often used fatigue as a tactical advantage. Overnight, Herr created his first protocol. Days later, that client emailed from Seoul: “What did you do? I just slept eight hours my first night.”
That moment planted the seed for what would eventually become Flykitt.
Why Pressure, Not Just Sleep, Causes Jet Lag
Herr’s breakthrough insight was that rapid cabin pressure changes trigger inflammation in the body — the equivalent of climbing an 8,000-foot mountain in 15 minutes. This, combined with sleep disruption and circadian misalignment, makes travel especially brutal. By tackling all three factors, Flykitt redefines what recovery in the air looks like.
From Pros to Frequent Flyers
Today, dozens of professional and Olympic teams use Flykitt, including U.S. Soccer, NFL teams, and elite athletes who need to perform the day they land. Beyond pros, Herr recently launched Flykitt Domestic, a new product aimed at reducing inflammation and fatigue on shorter flights.
The results? Travelers report being able to treat trips to Asia like short domestic hops — landing, performing, and returning home without losing days to recovery.
More Than Jet Lag
Flykitt is evolving into a complete performance ecosystem. The app doesn’t just handle flights — it also builds custom workouts based on any gym’s equipment and locates healthy restaurants worldwide.
We have the most advanced tech in the world to find healthy restaurants, whether you're in Bangkok or Bangalore or Sydney or London. So really, we want to make it easy and smooth to be healthy while you travel." - Andrew
Andrew Herr’s Flow Stack
Workout every day — a simple, low-tech anchor, with a current focus on longer runs.
King Orchards Tart Cherry Juice — his go-to recovery tool, stored in the freezer or in stick packs, cutting soreness and nearly doubling recovery speed after long sessions.
Blue light blocking glasses and a cold, dark room — essential for quality sleep and consistent recovery.
Shower before bed — raises body temperature, then cools it down to signal sleep, while also washing off allergens.
Flykitt Gen5 — Andrew is testing the newest version of his own system to push its evolution forward.
Salomon running pack — his favorite piece of gear for carrying essentials on the move without bounce.
Brooks running shoes — chosen for the right fit and arch support, not the brand name.
Wool or cotton clothing — a natural choice to minimize plastic contact during training and in hot conditions.
