Protein Supplies Australia WPI Whey Protein Isolate 1kg is a whey protein isolate powder for shoppers who want a larger repeat-use milk-based protein pouch.

Choose unflavoured, vanilla, banana, chocolate, strawberry or white choc caramel depending on taste and recipe use. The 1kg size suits shoppers who already know WPI fits their routine and want fewer reorders than a smaller pouch.

This range is best compared with whey concentrate, plant protein and egg-white protein by ingredient base, flavour choice, texture and serving flexibility. The unflavoured option is useful for recipes, while flavoured options are easier for simple shakes.

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 larger pouch to taste preference, allergen needs and repeat-use value.
