Can You Take Protein Powder on a Plane?

If you’re planning a holiday or travelling for work, staying on track with your fitness routine can be tricky — especially when it comes to nutrition. One of the most common questions fitness enthusiasts ask is: can you take protein powder on a plane?

The good news is yes, you can. However, there are a few important rules and travel tips to keep in mind to make sure your supplements make it through airport security without any hassle.

You can also stock up on your favourite travel-sized tubs and sample packs from Nutrition Now, featuring top brands like NXT, Naughty Boy, and Per4m.

Can You Take Protein Powder in Hand Luggage?

Yes, protein powder is allowed in your hand luggage on most airlines. The UK Civil Aviation Authority (CAA) and airport security across the UK and Ireland permit powders to be carried through airport checkpoints.

That said, there are a few guidelines to be aware of:

• You can bring powders in containers up to 350g (around 12oz) through security without issue.

• Anything larger may be subject to additional screening.

• It’s best to keep your protein powder in its original, clearly labelled packaging to avoid confusion.

If you’re flying internationally, check the airline’s website or the country’s import regulations, as some destinations have restrictions on bringing food supplements or powders.

For example, the NXT Pure Whey Deluxe 510g is an ideal travel-sized option — compact, resealable, and easy to fit into your luggage.

Can You Take Protein Powder in Checked Luggage?

Absolutely. If you’re taking a larger container of protein, such as Naughty Boy® Advanced Whey 2010g, it’s best to pack it in your checked baggage.

Here are a few tips for packing protein powder safely:

• Seal the tub tightly to prevent leaks.

• If you’re taking single servings, use labelled plastic bags or travel containers to save space.

• Keep the scoop inside the tub to make mixing easier when you arrive.

It’s a good idea to pack it near the top of your suitcase so that security staff can easily inspect it if needed.

How to Carry Protein Powder While Travelling

If you want to make things even simpler, pre-portion your protein before you travel. Using small, clear bags or shaker cups, measure out your servings — this saves time and prevents mess.

The Per4m Whey Protein 900g is a great choice for travel thanks to its lightweight tub and smooth, easy-mixing formula. Just add water or milk at your destination for a quick shake that keeps you on track.

Alternatively, single-serving sachets or sample boxes are ideal for short trips. They’re TSA and CAA-friendly and take up virtually no space in your bag.

Can You Bring Protein Shakes Through Airport Security?

Liquids are a different story. Pre-mixed protein shakes count as liquids, so they must follow the 100ml rule for hand luggage. That means you can only carry small ready-to-drink bottles in a clear 1-litre plastic bag.

If you want a full shake for your flight, bring an empty shaker and mix your protein with water after security. Most airports have water stations available, making this the easiest way to stay fuelled while travelling.

Final Thoughts

So, can you take protein powder on a plane? Yes — and it’s actually quite simple. Keep your powder under 350g in hand luggage, or pack larger tubs in your checked bag, and you’ll have no problems.

With travel-friendly options like NXT Pure Whey Deluxe 510g, Per4m Whey Protein 900g, and Naughty Boy® Advanced Whey 2010g, it’s never been easier to stay on top of your nutrition while you travel.
