FlyKitt Rescue


We discovered that inflammation is the key to jet lag. Based on our research with Navy SEALs and fighter pilots, we found that the pressure changes in flight cause the immune system to overreact, which then prevents resetting your circadian rhythm. This inflammation also causes low energy, brain fog, gut issues, low mood, and more.

FlyKitt Rescue is our post-flight formula for use when the inflammation has already started. It helps decrease inflammation, restore normal immune activity, support sleep, boost energy, and get you back on rhythm through a natural, timed supplement program.
