常见问题解答 (FAQ)

Frequently asked questions

Can you bring Creatine in a carry-on?

Yes — but containers over 12 oz (350 ml) of powder go in a separate X-ray bin; unclearable powder may be disposed of.

Can you pack Creatine in checked luggage?

Yes, any quantity is allowed in checked bags. Full-size tubs belong here.

Can you bring creatine through TSA?

Yes. Creatine is a powder, not a liquid, so the 3.4 oz rule does not apply. Up to 12 oz (350 ml) passes normally; containers above that go in a separate X-ray bin for extra screening.

Does protein powder count as a liquid for the 3-1-1 rule?

No — dry powders are exempt from the liquids rule. They instead fall under the separate 12 oz / 350 ml powder-screening rule in the US and the 350 ml/g total limit in Canada.

Can I bring protein powder on an international flight?

Security treats it like any powder. Sealed retail packaging is the smooth route through both screening and customs at agricultural-strict destinations; unmarked bags of loose white powder invite questions everywhere.
