What Is Whey Protein: The Beginner’s Guide

What Is Whey Protein: The Beginner’s Guide

What is whey protein? And what does it do? You may have seen or heard about whey protein online, in the gym, or on TV, but do you know if you should be using it? Here is the complete guide to help you find out!


What Is Whey Protein?

Whey is a natural by-product of milk that comes out of cheese production. During cheese making, milk is pasteurised, incubated, and incubation, which makes it coagulate into curd and whey. If you have ever opened a yoghurt and seen a little bit of liquid on top, you will have been looking at whey.

Whey Protein is a little more than the liquid on top of your yoghurt though. It goes through a special process to turn it into a fine powder for use in shakes, bars, and more. This process determines what type of whey the powder becomes.

Types Of Whey Protein


Continuous filtration of curds and whey liquid produces an 80% concentrated protein solution. Further microfiltration that we use at myvitamins can increase this concentration to 90%.


Removing water, lactose, and fat from the whey liquid results in protein isolate, which is even more concentrated at 95%.


This protein solution can then be pre-digested to help to break down amino acids into short chains to accelerate absorption.


Why should I Take Whey Protein?

Despite its reputation, whey protein isn’t just for muscle building, as increasing protein intake is thought to improve satiety. Whey protein also includes lactoferrin, beta-lactoglobulin, alpha-lactalbumin, and immunoglobulins, which are thought to have a range of benefits on our overall health.


What Is Protein Powder Good For?

In theory, you could drink gallons of milk instead. But cow’s milk contains both whey and casein protein, and so whey protein only makes up around 20%. Therefore, gulping litres of milk might provide you with a good source of whey protein but that amount of calcium, lactose and fat could cause some adverse health effects. That is where you might find a whey protein supplement particularly useful. So how do we use it?


How Should You Use Protein Powder?

Whey protein on its own doesn’t taste particularly great, so it often comes flavoured to be drunk as a shake. However, unflavoured whey protein can be added to foods and drinks, like smoothies and porridges, without affecting the taste!
