During the winter months, I also add 2 to 4 caps of Immune Renew daily to bolster my defensive reserves and substitute one daily tonic of Effer-C effervescent powder in place of my calcium ascorbate. I take along extra packets of Effer-C to add when my immune system is threatened, such as on my rescent flight. Immune Renew is an equal blend of 8 medicinal mushrooms and the Chinese Herb Astragalus membranaceous. Both medicinal mushrooms and Astragalus are known for boosting immune fighting T-cells, macrophages, and natural kiler cells.
The smaller travel bag that goes with me to my seat always contains a big bottle of water, organic nuts and snack bars such as the Real bars, Verta and In Your Face Snacks. I also take along fresh fruit and something for my plane meal such as yogurt, soup or leftover casserole from home. Airline food has always been sorely lacking, but now it''s non-existent unless you want to purchase one of the less-than-healthy "snack boxes".
