Whey is the liquid remaining after milk has been curdled and strained and is the primary ingredient in most protein powders.
When looking at purchasing some whey there are often 2 or 3 different choices. The most common types are whey concentrate and whey isolate.
- Whey concentrate contains both fat and carbohydrates & usually 80% protein.
- Whey isolate has been processed more than whey concentrate to remove the fat and lactose and is 90%+ protein. Because it has been processed more than whey concentrate, it is often more expensive.
It is worth remembering whey is naturally low in fat & carbohydrates - when comparing a major supplement retailer, there is only one major difference and that is the price!

Whey is most commonly used in protein shakes, which can be a very easy and low calorie way of ensuring that you consume sufficient protein. Whether this be part of a meal or as a convenience tool.
However, a protein shake is still a supplement and therefore should only be used as a supplement to your diet and not form a major part of your diet or protein intake.
Supplements are often expensive per gram of protein in comparison to food!
