Your Questions Answered

What is whey protein?

Whey protein is a high-quality protein powder derived from the liquid by-product of cheese production, known as whey. Packed with essential amino acids, it's an excellent supplement for muscle repair and growth, making it a go-to supplement for athletes and gym-goers.

How much whey protein powder should I have per day?

The amount of whey protein you have daily depends on several factors, including body weight, activity level, and overall protein requirements. A general guide suggests that 1.2 to 2.2 grams of protein per kilogram of body weight benefits those doing regular training or exercising. Every whey protein powder will have its own dosing information on the back, which you should follow. If in doubt, consult your clinician to tailor the suitable amount for your needs.

What is the difference between whey protein and whey isolate?

Whey isolate is a more refined form of whey protein, which goes through further processing to remove most fats and lactose. This means whey isolate has a higher protein content by weight than standard whey protein powder concentrates. This makes whey isolate an excellent option for those looking to increase their protein intake without the additional fats and carbohydrates or for individuals sensitive to lactose.

How is whey protein made?

Whey protein is made from the coagulation of milk during the cheese-making process, which separates the solid curds from the liquid whey. The liquid is then pasteurised and dried into a powder. Whey protein powder is a great supplement that can be easily mixed into shakes, smoothies, and other recipes to increase protein intake.
