Glutathione could be something to look into.
Around here, the S. Korean versions tend to get picked over the Chinese ones.
Doing a bit of digging on it might be worthwhile for you.
For someone who flies as often as you do, glutathione might lend a hand in supporting cellular and immune resilience by countering oxidative stress brought on by high-altitude air, tiredness, and packed terminals — that said, ordinary oral versions tend to break down readily in the digestive tract unless they come as liposomal, acetylated, or are given through IV/topical routes.

Ways Glutathione Can Benefit Travelers
- Master Antioxidant: It shields immune cells (such as white blood cells) against oxidative stress and inflammation set off by flying, dry cabin air, and insufficient sleep.
- Antioxidant Recycling: It assists in recycling and recharging other antioxidants that support immunity, including Vitamin C and Vitamin E.
- Detoxification: It supports the liver and cellular pathways in coping with environmental stressors tied to travel. [1, 2, 3, 4]
Key Points to Keep in Mind When Supplementing
- Absorption Challenges: Plain, generic oral glutathione pills don't get absorbed well, since they have a tendency to break down in the gut. [1, 2, 3]
- Better Delivery Options: When people do take glutathione, they frequently turn to liposomal glutathione (encased in a fat-based shell to improve absorption), S-acetyl-glutathione, precursors such as N-acetyl-cysteine (NAC) that assist the body in producing its own glutathione, or specific IV/topical uses. [1, 2, 3]
- Not a Substitute for Basics: Medical and health resources stress that supplements aren't some magic shield. Fundamental habits—including consistent hydration, handwashing, adequate sleep, and proper nutrition—stay the most dependable means of guarding your immune system while traveling
