She stepped off the plane in London at 6 AM, walked straight into boardroom negotiations, and closed a major deal. While her competitors nursed coffee and struggled through business trip jet lag, she was sharp, focused, and fully present.

What made the difference? A patented system initially designed for Navy SEALs that’s now quietly revolutionizing how elite business travelers perform internationally.

As a full-time traveler, I’ve spent more hours on a plane than I care to admit, and when I first encountered Flykitt, my initial reaction was, “Another travel supplement promising to solve jet lag? Haven’t we heard this before?”

But the more I researched founder Andrew Herr’s background and the science behind the Flykitt Complete Jet Lag + Flight Inflammation System, the more compelling the evidence became.

The Military Discovery That Changed Everything

Andrew Herr spent seven years running human performance programs for U.S. Military Special Operations. Working with Navy SEALs and fighter pilots who couldn’t afford performance degradation, his team made a crucial discovery that explains why traditional jet lag advice fails.

The breakthrough wasn’t about sleep schedules or hydration, which almost all jet lag advice revolves around. Their research showed cabin pressure changes trigger inflammation, which interferes with circadian rhythms, creating mental fog and fatigue. Traditional advice like adjusting sleep schedules or drinking more water only treats symptoms, not the underlying issue.

Managing both the body’s inflammatory response and circadian alignment is critical for maintaining performance during international travel. The team’s findings laid the groundwork for solutions that let travelers arrive alert, focused, and ready to perform at their best.

What Makes Flykitt Different?

Flykitt International offers several key advantages:

• Contains four targeted supplement formulations based on military research
• Uses a protocol addressing both inflammation and circadian disruption
• Includes precision-timed blue light blocking glasses
• Features app-customized protocols for your specific itinerary
• Works during transit without lengthy pre-adjustment periods

The Science: What’s In The Packs

Flykitt International includes four research-backed formulations, each targeting a specific aspect of travel stress. All use highly bioavailable nutrient forms and are timed for maximum effectiveness via the Flykitt app:

• ADVANCE: Activated forms of Vitamin B6 and B12 support energy production and help realign circadian rhythms disrupted by international travel. These methylated forms are designed for faster absorption and more reliable effectiveness than standard B vitamins, helping travelers stay alert, focused, and ready to perform immediately upon arrival.*
• PROTECT: Organic pomegranate extract combined with Vitamin C helps reduce inflammation triggered by cabin pressure changes. By combating oxidative stress that contributes to fatigue and mental fog, PROTECT supports overall recovery and resilience during and after long flights.*
• MELLOW: Magnesium glycinate paired with melatonin improves sleep quality without next-day grogginess. The glycinate form enhances absorption, promoting restorative rest and allowing travelers to recover efficiently, even during short or disrupted sleep windows.*
• SUSTAIN: High-dose omega-3 fatty acids (EPA and DHA) reduce inflammation and support cognitive function. SUSTAIN helps maintain mental clarity, focus, and decision-making ability during recovery, ensuring travelers are prepared for critical work immediately after landing.*

Each supplement pack is individually sealed and labeled with specific timing instructions generated by the app based on your flight details and circadian preferences.

Why You Can’t Just Buy These At CVS

While the individual ingredients in Flykitt may exist elsewhere, it’s the formulation, timing, and integration that make the system unique. Standard melatonin doses vary widely, and generic B vitamins often use forms with poor absorption. Additionally, most omega-3 supplements lack sufficient EPA/DHA ratios for their anti-inflammatory effects. 

Taking random supplements without coordination won’t address the root problem. The Flykitt Complete Jet Lag + Flight Inflammation System combines targeted compounds with precise light exposure, meal timing, and sleep schedules to shift circadian rhythms and reduce jet-lag symptoms effectively.

With Flykitt, there’s no need to spend hours researching doses, nutrient forms, and timing protocols. The app provides exact instructions for when to take each supplement, when to use the blue-light filtering glasses, and how to align meals and sleep with your flight schedule. What you get is a fully integrated, automated system that addresses the underlying causes of jet lag, not just the symptoms.

The Business Performance Investment

Jet lag isn’t just uncomfortable; it is a measurable drain on corporate performance. In the $1.57 trillion U.S. business travel industry, each international trip can cost companies an average of $662 in lost productivity. Executives averaging 6.8 international trips per year risk $4,502 annually in lost performance, and these costs multiply quickly across teams.

The impact is immediate. Jet-lagged executives may experience impaired decision-making, miss critical details, and perform below their usual standard in high-stakes negotiations. One poorly executed presentation or delayed decision can set back months of relationship-building and business development.

Smart organizations recognize jet-lag mitigation as a strategic performance investment rather than a minor travel perk. Compared with the potential cost of lost productivity, tools like Flykitt help executives arrive alert, focused, and ready to perform from the moment they land.

But does it work?

Flykitt reports a 93% success rate in user surveys, although individual results may vary based on health, travel frequency, and adherence to the protocol. For context, Timeshifter shows 96% effectiveness based on over 130,000 post-flight surveys, while melatonin research indicates 50–90% success rates in multiple randomized controlled trials.

Flykitt founder Andrew Herr has stated that the company is “working on applying for grants” to run their first randomized controlled trial. Current effectiveness claims are based on user feedback rather than peer-reviewed studies.

User testimonials reveal consistent patterns. One family traveling to Finland reported: “I was pretty skeptical going in, but everyone felt amazing on arrival and return. I bought kits for all four of us and it worked for each of us.”

Fully Automated System For Busy Travelers

The Flykitt app eliminates guesswork by providing exact timing for every element. Enter your flight details, personal sleep preferences, and any dietary restrictions. The app generates a customized plan with push notifications telling you precisely when to take each supplement, wear the glasses, eat meals, and target sleep windows.

Flight delays or itinerary changes? The app updates your protocol automatically. No complex calculations or confusing instructions.

The Investment Perspective

At $99+ per international trip, the Flykitt Complete Jet Lag + Flight Inflammation System costs more than alternatives I’ve researched. Budget travelers can use free solutions like Jet Lag Rooster or pay $24.99 annually for Timeshifter’s unlimited plans. Light therapy glasses range $69 to $299 for lifetime use.

But consider what you’re actually purchasing: formulations developed through military research, precision timing technology, blue light filtering glasses engineered for travel, and app-driven customization that adapts to your specific needs.

More importantly, calculate the cost of suboptimal performance during critical business travel. Missing peak cognitive function during international negotiations can set back months of relationship building.

For executives averaging 6.8 international trips yearly, the annual cost approaches $670. That’s still less than the productivity loss from one severely jet-lagged trip. Considering these factors, Flykitt transforms this from an expense into a performance investment.

Measurable Results, Risk-Free

With a 30-day money-back guarantee, you can test the system on actual business trips and return it if results don’t meet your performance standards.*

For business travelers who can’t afford to be exhausted, Flykitt International offers an approach to eliminating jet lag instead of just managing the aftermath. While competitors focus on preparation protocols, you’ll be ready to perform from the moment you land.

Based on my research, Flykitt fills a specific niche for travelers who prioritize convenience and are willing to pay premium prices for unproven but promising innovation. Whether that innovation justifies the cost compared to established alternatives with transparent effectiveness data remains a personal calculation.
