Informed Choice is a global standard in sports nutrition quality control. The certification means that this product has been regularly tested for banned substances by a world-class anti-doping laboratory, providing assurance for athletes.

The number of servings can vary slightly based on the exact scoop size and density, but a 900g tub typically provides around 29-30 servings when using the recommended one-scoop serving size.

While technically possible, mixing whey protein with very hot liquids is generally not recommended. High heat can denature (cook) the protein, which doesn't harm its nutritional value but can change its texture, making it lumpy or gritty. For best results, use cold or room-temperature liquids.

Yes, as long as it contains no animal-derived ingredients other than dairy (which whey protein is). The product description does not indicate otherwise, making it generally suitable for ovo-lacto vegetarians. It is not suitable for vegans.

As a whey protein derived from milk, this product naturally contains lactose. While the processing for whey protein isolate can reduce lactose content significantly, it is not entirely lactose-free. Individuals with severe lactose intolerance should consult a healthcare professional or consider lactose-free protein alternatives.

Absolutely. Protein is an essential macronutrient for everyone, including women, to support muscle growth, recovery, and overall health. There are no gender-specific contraindications for using this product.

Ensure you're using cold liquid, as warmer liquids can sometimes cause clumping. Use a shaker bottle with a mixing ball or mesh screen, or a blender. Add the liquid first, then the powder, before shaking or blending.

The unflavoured variant is designed for versatility. Mix it with juice, milk (dairy or non-dairy), or blend it into a fruit smoothie. You can also add a small amount of unsweetened cocoa powder, a splash of vanilla extract, or natural sweeteners like stevia to enhance the taste.

Start with a smaller serving size to allow your body to adjust. Ensure you are adequately hydrated throughout the day. While whey protein is generally well-tolerated, individuals sensitive to lactose might experience mild issues. If discomfort persists, consult a healthcare professional.
