Does FlyKitt Work? Buying to Beat Jet Lag

I’m just home from a lovely trip to China. It wasn’t for work or anything, just for fun. But when ever I go on a big holiday like this, I shortlist some items to test out. The kinds of items you can best test out on a holiday, like the Samsung Galaxy S25 Ultra.

Another key piece of kit for this holiday was FlyKitt, a pack you purchase to overcome jet lag on a holiday. Here’s what how I got on with it.

What is FlyKitt?

I once read that there are no magic cures for time zones. Travelling long haul can, and likely will, take its toll on you. But I disagree with the sentiment that there is nothing you can do. As I’ve shown in the past, apps like Timeshifter help you manage your circadian rhythms and light exposure to regulate your energy as best you can. Even on flights, the crew will usually tailor lighting and food to best prepare you for your arrival timezone.

FlyKitt builds on the idea of an app and regulating your body clock by adding in a pack of supplements and blue light glasses.

The FlyKitt app takes in your flight details and then tells you when to take your supplements.

Advance prepares your body for the upcoming travel stress by boosting energy metabolism and balancing your circadian rhythm. Protect shields your body from the oxidative stress and inflammation caused by altitude changes and cabin pressure. I also wore compression socks as is regularly recommended for long haul flights.

Mellow was my favourite. You take this around your intended bedtime in your destination’s time zone. Mellow encourages restful sleep to help reset your internal clock and ease the transition across time zones. Included in the ingredients is melatonin to help you rest.

Finally, there’s Sustain which you typically take after your flight, to support ongoing recovery and daytime energy.

The pack also included some instant coffee and two sachets of “Circadian Reset”, which was just lots of sugar from what I could see at the bottom of my cup.

How Does FlyKitt Work?

The idea behind FlyKitt is to give you an app to manage your energy, and supplements to optimise your body’s reaction to the stress and unusual times of long haul travel. Before travel, the app told me the best time to go to sleep based on my flight details, and when to start taking supplements.

Dublin to Beijing, is a direct route with ten hours of fly time. Shortly after takeoff, the app told me to take some more supplements and to don my blue light glasses. These glasses are designed to filter out the specific wavelengths of blue light that can suppress melatonin production, the hormone responsible for sleep regulation.

By wearing them at strategic times (as guided by the Flykitt app), you can effectively “trick” your body into preparing for sleep earlier or staying alert longer, depending on your destination’s time zone. This light management helps shift your internal clock more smoothly, making it easier to fall asleep and wake up in line with your new schedule.

Between the Mellow supplements and the blue light glasses, I slept for about 8 hours on the flight. Something I’ve never even nearly achieved while travelling before. I woke up once to use the bathroom, but felt the blue light glasses, which I fell asleep wearing, kept my mind in a state of sleep. So when I went back to my seat, I fell back asleep.

The Goosed Verdict: FlyKitt – Is It Worth It?

The big question for me after this trip remains whether or not I would buy a FlyKitt for myself considering that FlyKitt sent this over to me for testing.

It’s really not a cheap product. €90 will get you a FlyKitt Starter pack, which includes the blue light glasses and enough supplements for a round trip. After this, a FlyKitt refill will set you back about €60.

With Timeshifter, I said you need to understand that you’re paying to have the holiday of a lifetime run smoothly by doing everything you can to kill jet lag. This is a sizeable price jump. I will accept that I now use the blue light glasses before bed and am looking into getting some melatonin (which you can’t buy in Ireland). One additional point is that some of the capsule were quite big, if swallowing large tablets might be a problem for you.

I think the final assessment is that for €90, if you have a big long haul trip coming up, this isn’t a bad investment. Oddly is buying just the refills at €60 feels harder when a good sleep only needs melatonin and the glasses.

But I do have to admit that the sleep I had with FlyKitt, both on the flight and on night one in China was some of the best sleep I’ve ever had.
