Protein Shake / Powder
Common questions
No, dry protein powder is not a liquid and is not subject to the 100ml liquid rule. However, TSA and some other security agencies may screen powder containers over 350ml (12oz) separately.
Pre-mixed shakes are liquid and must follow the 100ml/3.4oz carry-on rule. Pack larger quantities in checked luggage in sealed containers.
Large quantities of any fine powder can trigger additional screening. TSA introduced extra powder screening measures in 2018. Consider packing in smaller sealed bags or carrying the original labelled container.
No weight limit exists, but the US TSA recommends containers under 350ml (12oz) to avoid extra screening. Other countries have no specific quantity limits for powder.
