Best protein bars in Bangkok: what to buy and where
A good protein bar delivers roughly 15 to 20 g of protein for a convenient snack when you cannot cook. In Bangkok, UnReal Supplements on Sukhumvit Soi 24 stocks genuine Barebells, Kauai and BSN Protein Crisp bars by the box, with pickup at the gym two minutes from Phrom Phong BTS and delivery across Thailand. Read the label for protein per bar versus sugar and total calories before you buy.
What makes a protein bar worth buying
A protein bar is a convenient way to add 15 to 20 g of protein when a proper meal is not an option, not a health food by default. The useful ones are high in protein relative to their calories and low in added sugar. Many bars marketed as healthy are really candy with a protein claim, so the label matters more than the front of the wrapper.
For most training adults the daily target is roughly 1.6 to 2.2 g of protein per kg of bodyweight from all sources. A bar helps fill the gap food leaves on a busy day or a travel day, alongside your main protein sources.
How to read a protein bar label
- Protein per bar: aim for 15 g or more. A bar with 6 to 8 g is a snack, not a protein source.
- Sugar: lower is better. Compare total sugar to protein; you want more protein than sugar.
- Calories: a bar is a snack, so 200 to 250 kcal is normal. Much higher and it is closer to a meal-replacement or a candy bar.
- Fibre and ingredients: whole recognisable ingredients over long chemical lists, and watch for sugar alcohols if they upset your stomach.
Protein bars in stock at UnReal Supplements
The shop carries protein bars by the box so you keep a steady supply rather than buying one at a time. Barebells bars are a popular lower-sugar option at around 20 g of protein per 55 g bar. Kauai and BSN Protein Crisp give you more flavour variety, sold as boxes of twelve.
Buying in person at the gym means you can check the box, the seal and the expiry before you pay, which an online marketplace listing cannot offer.
