About Whey Protein supplements in NZ
Whey protein is derived from milk during the cheese-making process and is one of the most studied and effective supplements for muscle growth and recovery. It is a complete protein, meaning it contains all nine essential amino acids. Whey is fast-digesting, making it ideal for post-workout consumption when muscles need rapid nutrient delivery.
Whey Protein — Frequently Asked Questions
Whey concentrate (WPC) typically contains 70–80% protein and retains more of the natural fats and lactose from milk. Whey isolate (WPI) is further processed to achieve 90%+ protein content with minimal fat and lactose — making it a better option for those who are lactose sensitive or want a leaner supplement.
Most whey protein products have a serving size of 25–35g of protein per scoop. One to two scoops per day is typical depending on your total daily protein needs. Always check the label for the specific product's recommended serving.
Some people experience bloating from whey concentrate due to its lactose content. Switching to whey isolate, which has most lactose removed, or a plant-based protein, usually resolves this.
