Searching for a quality protein bar in Singapore in 2026? You may have come across the thinkThin brand (now called think!) — an American protein bar popular for its high-protein, low-sugar positioning. While think! bars are not currently stocked at local retailers in Singapore, the demand for convenient, high-protein snacks has never been higher. This guide covers what makes a great protein bar, how think! stacks up on paper, and which locally available protein bars in Singapore deliver better value and convenience.
What Is a Think Protein Bar?
The think! (formerly thinkThin) protein bar is a US-based brand known for producing high-protein, low-sugar snack bars. Their flagship bars contain 20g of protein per bar with 0g sugar, using a blend of whey protein isolate and milk protein isolate. Popular flavours include Brownie Crunch, Chunky Chocolate Peanut, and Salted Caramel.
Key specs (think! High Protein Bar): - Protein: 20g per bar - Sugar: 0g - Calories: ~230–240 kcal - Format: Chocolate-coated snack bar - Available in Singapore: ❌ Not stocked locally
While the product quality is respectable, think! bars are imported and unavailable through major Singapore supplement retailers, making them difficult to purchase consistently. Shipping from the US adds cost and delivery time.
The Best Protein Bars Available in Singapore Right Now
Here are the top protein bars you can buy locally today.
1. Barebells Protein Bar — Best Overall

Barebells is the best-tasting protein bar available in Singapore in 2026. Originally from Sweden, Barebells has built one of the most loyal followings in the global protein snack market — and for good reason. Each bar delivers 20g of protein from a milk protein blend with no added sugar, wrapped in a genuinely indulgent chocolate coating that rivals real confectionery.
Why Barebells wins: - 20g protein | 0g added sugar | ~200–210 kcal - Flavours include Cookies & Cream, Caramel Cashew, Hazelnut & Nougat, Peanut Caramel - Texture and taste are consistently rated among the best of any protein bar globally - Available at Ultimate Sup Singapore with fast local delivery
Verdict: If you only buy one protein bar brand in Singapore, make it Barebells. It solves the classic protein bar problem — bars that taste like cardboard or bars that are basically candy — by delivering genuine dessert-level flavour with a clean macronutrient profile.

What to Look for in a Protein Bar in Singapore
When choosing a protein bar for the Singapore climate and lifestyle, consider:
- Protein source — whey isolate and milk protein are most bioavailable; plant proteins from pea or rice are best for vegans
- Sugar content — aim for under 5g of sugar per bar
- Fibre — higher fibre slows digestion and keeps you full longer
- Texture in heat — some bars melt or become too soft in Singapore's humidity; Barebells and Quest hold up well
- Price per bar — buying boxes of 12 is always more cost-effective than individual bars

Frequently Asked Questions
Are think protein bars available in Singapore?
think! protein bars are not currently stocked at local Singapore retailers including Ultimate Sup. You can import them, but shipping costs and delivery times make locally available alternatives like Barebells and Quest more practical.
What is the best protein bar in Singapore in 2026?
Barebells is the best protein bar in Singapore in 2026 for taste, texture, and nutritional profile. Quest is the best choice if you prioritise high fibre content alongside your protein intake.
How much protein should a protein bar have?
Look for protein bars with at least 15–20g of protein per bar to make them worth the calorie cost as a supplement snack. Bars with fewer than 10g of protein are closer to ordinary snack bars with a marketing spin.
Can I eat a protein bar instead of a meal?
Protein bars are designed as snacks, not meal replacements. A 200–240 kcal bar is significantly less than a typical meal. For meal replacement, look for dedicated meal replacement shakes or bars with 400+ kcal and a full micronutrient profile.
