TSA Rules: When you're passing through security, ensure that your gummy vitamins are packed in compliance with the TSA's 3-1-1 rule. Each container should be no more than 3.4 ounces (100 milliliters) and placed in a quart-sized, resealable plastic bag.

To pack gummy vitamins for travel in 2026, the most critical factor is temperature control and moisture protection. If you are traveling to a hot climate, keep your gummies in your carry-on luggage rather than a checked bag, as the aircraft hold can become extremely warm on the tarmac, causing the gummies to melt into a single, inseparable mass. It is best to keep them in their original bottle to avoid any issues with TSA or customs, who prefer to see clearly labeled supplements. If you must use a pill organizer, ensure it is airtight to prevent the gummies from becoming sticky or hardening due to humidity changes. For long-haul flights, placing a small silica gel packet (often found in the original bottle) in your travel container can help maintain their texture. In 2026, some travelers also use small, insulated "snack pouches" to keep their vitamins cool during transit, especially if they are traveling to humid tropical destinations where the "blooming" of the gelatin can occur.
