How many Creatine / Protein Powder can you bring on a plane?
Standard carry-on baggage size allowances apply; TSA publishes no individual numerical cap for personal use.
Are brand models like Optimum Nutrition Micronized allowed through airport security?
Yes. Major brands such as Optimum Nutrition Micronized, Thorne Creatine, BulkSupplements must comply with standard security limits based on physical properties rather than brand labels.
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.
