How To Choose A Whey Protein Powder   

Whey protein is one of the most popular and widely consumed sports supplement products in the world. But there are so many forms of whey, from whey protein concentrate and whey protein isolate to hydrolysed whey protein isolate. With so much to choose from, how can you select the best whey for your diet and goals? 

Let’s take a closer look at the different types of whey protein, and why you should add them to your next order. 

 

What Is Whey Protein? 

Whey protein powder is the powdered form of whey, which is a byproduct of milk. When milk is separated into its component parts, we are left with whey and casein. Are we the only ones old enough to remember the nursery rhyme about Little Miss Muffet, eating her “curds and whey”? Curds are the casein (think curd cheese) and the rest is whey. Cow’s milk has around 20% whey to 80% casein content. 

Whey is a popular choice of protein because it is so easy to use, convenient to store, and has impressive nutritional benefits. It is digested quickly, is high in important amino acids, and contains glutamine. Whey contains very little carbohydrate and fat, so you are getting tons of protein per serving. 

 

How Is Whey Protein Made? 

Every type of whey goes through a different manufacturing process – we’ll go into this shortly. But all whey starts life as a component part of milk. The liquid whey is filtered off, before being freeze-dried and sprayed into the powder form we all recognise. 

 

Is Whey A Food Or A Supplement? 

This is up for debate, but we think whey is a legitimate real food. After all, it’s really just powdered milk (or part of milk, anyway). Although whey protein is developed and sold by sports supplement companies like us, it’s really a convenient form of natural food. What do you think? Is whey food or supplement? 

 

The Differences Between Types Of Whey 

The most common kind of whey protein is Whey Protein Concentrate (WPC). WPC tends to be 80-82% protein, with small amounts of carbohydrates (from milk sugars) and fats. WPC is widely available and tends to have a massive array of flavours to choose from. WPC is a solid choice for anyone who wants a convenient way to add more protein to their diet. Even though it contains more carbohydrate and fat than whey isolates, the numbers are pretty minimal, so it’s fine for anyone on a normal diet, a mass gain phase, or even a cutting diet. WPC is a complete protein, containing all nine of the essential amino acids and BCAAs you need. It’s the workhorse of the whey protein stable: reliable and ready to go with everything you need. 

Whey Protein Isolate (WPI) is higher in protein at around 90%, with less carbohydrate and fat than WPC. It has gone through a further filtration process to remove more of the sugars, fats, and lactose. This makes WPI a good choice for anyone who is really watching their macros, or who wants to minimise lactose. It’s no good for anyone who is intolerant or allergic to dairy, of course. But it does have less lactose than WPI. It’s also thinner than WPC, so you might find WPC a more satisfying drink. 

Hydrolysed Whey Protein Isolate (HWPI) has gone through a hydrolysation process to break the proteins down into smaller elements, so it is digested extremely quickly. This makes HWPI ideal for taking just before training, or even for adding to an intra workout drink. 

Whey protein products can range from pure protein with nothing added, to complete all-in-one solutions with smart carb sources, digestive enzymes, MCT fats and more. 

 

Choosing The Best Whey Protein  

A quality WPC is a great choice if you want to bump up your protein intake, or have a whey protein for adding to smoothies, proats, or other protein concoctions. Choose a really good WPC like CNP Pro Whey (which also contains whey protein isolate) or our ever-popular Pro Peptide and it will stand you in great stead all year round, whether you are training, competing, massing or cutting. 

If you prefer to minimise lactose or really need to get ultra specific with your macros, then a WPI like CNP Pro Isolate will help you keep fats to the bare minimum and avoid milk sugar carbs and lactose. WPI isn’t lactose free, but it’s extremely low in lactose and carbs.
