Live prices
Looking for affordable protein powder without leaving your local Coles? This comparison shows what's currently available sorted by price, accurate as of May 2026 and updated regularly. Right now, Coles' own Wellness Road Pea Protein sits at $10, making it the cheapest option on the shelf. If you prefer whey or vegan blends, you'll find options from Happy Way and Muscle Nation starting around $13.50 to $17.50. When comparing different sized tubs, always check the cost per gram of protein rather than just the sticker price. A larger container might look expensive upfront but could work out cheaper per serve. The table below breaks down the actual value of each product so you can see which options give you more protein for your dollar, whether you're after plant-based, whey, or casein formulas.
Check the price per 100g of actual protein, not just the tub price. A $40 tub with 80% protein beats a $30 tub with 50% protein.
How the live ProteinPrice Value Score is calculated
Coles Wellness Road Pea Protein ranks 1st on this list with a perfect 10/10 value score. At $2 per 100g, it's the most affordable option available. Being unflavoured means you can mix it into anything without clashing tastes, though some might prefer a ready-to-drink flavoured option. It's plant-based, making it suitable for vegans and those avoiding dairy.
Muscle Nation's Custard Protein ranks 3rd on this list at $17.50 for 400g. At $4.38 per 100g, it's positioned in the mid-range rather than truly budget territory. The cookies and cream flavour offers variety if you're after something different from standard chocolate or vanilla. Its value score of 2.3 out of 10 suggests you're paying more for the brand name and unique custard format than pure protein value.
Muscle Nation's Custard Casein ranks 5th on this list at $17.50, currently half price at Coles. With a perfect 10/10 value score, it's solid for overnight protein release given casein's slow digestion. The cookies and cream flavour adds variety to the usual whey options. At 2.87 cents per gram of protein, it's genuinely affordable for a specialty casein product, though you'll need to grab it during this sale.
