Carry-on details
Allowed. Vitamins and supplements as pills, capsules, or gummies have no quantity limit in carry-on — they aren't a liquid, so the 3-1-1 rule doesn't apply, and original packaging isn't required (though it helps avoid extra questions). Liquid vitamins or supplements follow the standard 3.4 oz (100 ml) per container / quart-bag rule, since they generally don't qualify as medically necessary the way a prescribed medication does. Powdered supplements (like protein powder) are allowed in carry-on in containers of 12 oz (350 ml) or less; larger containers need extra screening or should go in checked baggage.
Checked-bag details
Allowed without restriction, in pill, liquid, or powder form.
Special instructions
Unlabeled pills or powder can look ambiguous on an X-ray and lead to additional screening — original, labeled packaging makes the process faster.
