Understanding protein types
What is the difference between whey isolate and whey concentrate?
Whey isolate is usually processed further, which often means more protein per serving and less lactose. Whey concentrate is typically less refined and can contain slightly more fat and carbohydrate. Neither is automatically better. It depends on your budget, digestion and what you want from the shake.
How do people usually use protein powder?
Most people use it to help top up daily protein intake. That might mean a shake after training, a scoop in porridge or a quick option between meals. It is a convenience product, not a requirement for everyone.
What should I check first on a label?
Start with the protein per serving, the size of the serving, the ingredient list and whether the format suits your diet. Then look at extras such as sweeteners, fibre, creatine or vitamins if they matter to you.
