FAQs



What is whey protein powder?

Whey protein powder is a supplement derived from whey, the liquid portion of milk that separates during cheese production. It's processed and dried into powder form, creating a concentrated protein source that contains all nine essential amino acids.


Whey powder comes in different forms including concentrate, isolate, and hydrolysate. Concentrate typically contains 70-80% protein, whilst isolate undergoes additional processing to reach 90% or higher protein content with reduced lactose and fat.


How is whey protein isolate different from whey protein concentrate?

Whey protein isolate undergoes more extensive processing than concentrate, resulting in higher protein content per serving (typically 90%+ versus 70-80%). This additional filtration removes more lactose, fat, and carbohydrates from the final product.


Concentrate retains more of the beneficial compounds found in whey, including immunoglobulins and lactoferrin, though in smaller amounts. Isolate suits those who want maximum protein with minimal calories from other macronutrients, whilst concentrate offers a more economical option with a slightly richer nutritional profile.


How do I choose the right whey protein powder?

Consider your nutritional goals, dietary preferences, and budget when selecting whey protein powders. If you're managing your calorie intake closely, isolate provides more protein with fewer calories from fats and carbohydrates.


Those sensitive to lactose often find isolate easier to digest due to its lower lactose content. Flavour preference matters too – try sample sizes before committing to larger quantities, and check the protein content per serving to ensure it meets your requirements.


How much whey protein powder should I take?

The amount depends on your overall protein requirements, which vary based on activity level, body weight, and training goals. A typical serving provides 20-25g of protein, though your total daily protein intake should come from a combination of whole foods and supplements.


Many people take one to three servings daily, timing them around workouts or using them to supplement meals. Check your total protein intake across all food sources to ensure you're meeting your individual needs without excessive consumption.


Can I use whey protein powder for cooking and baking?

Whey protein powder works well in various recipes beyond shakes. You can add it to pancakes, porridge, smoothie bowls, protein balls, and baked goods like muffins or protein bars.


Keep in mind that high heat can affect texture, sometimes making baked goods denser. Start by replacing a portion of flour in recipes rather than substituting entirely, and experiment with liquid ratios as whey powder absorbs moisture differently than traditional flour.


What flavours of whey protein are available?

Myprotein offers whey protein powders in over 40 flavours, ranging from classic options like Chocolate Smooth, Vanilla, and Strawberry Cream to more adventurous choices such as Salted Caramel, Birthday Cake, and Rocky Road.


Unflavoured versions are also available for those who prefer to add their own flavourings or use the powder in savoury recipes. Sample pouches let you test different flavours before purchasing larger quantities.


How do I mix whey protein powder?

Add one scoop (typically 25-30g) to 200-300ml of water or milk in a shaker bottle. Seal the lid and shake vigorously for 10-15 seconds until fully mixed. The powder dissolves more easily in room temperature or cool liquids rather than very cold ones.


For smoothies, blend the powder with your chosen liquids, fruits, and other ingredients. Using a blender creates a smoother consistency than hand-shaking, particularly when adding ingredients like frozen fruit or nut butters.


Who developed Myprotein's whey protein powders?

Myprotein's expert nutritionists developed these whey protein formulations, focusing on quality protein sources, effective dosing, and great taste. The range includes options tested under the Informed Sport programme, providing additional assurance for athletes who undergo regular testing.


Each product undergoes rigorous quality control processes to ensure it meets the stated nutritional profile. The team continuously refines formulations based on customer feedback and advances in sports nutrition science.


Are Myprotein whey protein products tested for banned substances?

Selected Myprotein whey protein products carry Informed Sport certification, meaning they're tested for banned substances on the World Anti-Doping Agency (WADA) list. This certification provides additional confidence for competitive athletes subject to drug testing.


Products with Informed Sport certification are clearly marked on their packaging and product pages. If you compete in tested sports, look for this logo when selecting your whey protein powder.


How should I store whey protein powder?

Keep whey protein powder in a cool, dry place away from direct sunlight and moisture. Seal the bag or container tightly after each use to prevent the powder from absorbing humidity, which can cause clumping.


Avoid storing it in humid environments like bathrooms, and use a clean, dry scoop each time to prevent introducing moisture into the container. Properly stored whey powder maintains its quality until the best-before date printed on the packaging.
