Protein Supplies Australia WPI Whey Protein Isolate 500g is a whey protein isolate powder for shoppers who want a lighter milk-based protein format in a trial-friendly pouch.

Choose chocolate, vanilla, banana, unflavoured, strawberry or white choc caramel depending on taste and how you plan to use it. The 500g size is useful when you want a lower-commitment way to compare flavour, sweetness and mixability before moving to a larger bag.

This range is best compared by flavour, ingredient panel and how you plan to use it in shakes, smoothies, oats or simple protein baking. The unflavoured option is the most flexible for recipes, while flavoured options suit shoppers who want a ready-to-mix shake.

Mix the labelled serve with water, milk or your preferred milk alternative, then reseal after use. Review the milk allergen and sports-food warning before purchase, especially when buying for children, pregnancy, breastfeeding or supervised diets.

For best comparison, check the flavour selector, pack size and ingredient panel together before adding to cart. This helps match the pouch to taste preference, allergen needs and how often the product will be used.
