TSA Guidelines for Vitamins and Supplements

1. Solid Supplements (Pills, Capsules, Gummies)

Solid forms of supplements are the easiest to travel with. Tablets, capsules, and gummies are allowed in both carry-on and checked luggage with no special restrictions. You don’t need the original packaging, though a labeled pill organizer can make things easier during security checks.

2. Liquid Supplements

Liquid vitamins, syrups, or drinkable supplements must follow the TSA 3-1-1 rule for carry-ons:

• Each container must be 3.4 ounces (100 ml) or less

• All containers must fit into a single quart-sized clear plastic bag

Larger containers are allowed in checked baggage but not in your carry-on.

3. Powdered Supplements

Protein powders, greens powders, or other powdered supplements are also allowed. However, if you carry more than 12 ounces (350 ml), TSA may require you to place them in a separate bin for additional screening. To avoid hassle, pack larger amounts in your checked luggage.

Packing Tips for Smooth Travel

• Label and Organize: Keeping your supplements labeled helps TSA officers identify them quickly.

• Use Travel-Friendly Packaging: Single-dose packets or a weekly pill organizer save space and make routines easier to manage on the go.

• Separate Liquids: Store liquid vitamins in your quart-sized liquids bag for quick screening.

• Protect Against Spills: Double-bag powders and liquids to prevent leaks inside your luggage.

• Mind the Climate: Some supplements, like probiotics or oils, are sensitive to heat. Consider insulated cases if traveling to warm destinations.

International Travel Considerations

While TSA rules are straightforward, international regulations can vary. Some countries restrict certain supplements or require them to be declared at customs. To avoid problems:

• Research the supplement laws of your destination in advance

• Keep original packaging and documentation if possible

• Carry only the amount you’ll need during your trip

By packing smartly, labeling clearly, and keeping essentials in your carry-on, you can maintain your health routine no matter where your travels take you. A little preparation ensures your supplements fly as smoothly as you do.
