Whey Protein: Why You Shouldn’t Just Buy The Cheapest & How Premium Grade Whey Could Be Better

Article At A Glance:

Have you ever walked into a Supplements store to buy some whey protein? Do you find yourself constantly asking, which protein powder do I buy?

The market is flooded with online sports brands practically shouting from the rooftops that their whey protein powder is the cheapest (and the best for you) but is it really?

In this article, we will discuss some of the differences you may find between protein powder brands, and learn that sometimes paying more gives you better bang for your buck.

Let’s dive in.

What is Whey Protein

The best way to wrap your head around whey protein is if we zoom out and look at the process of making cheese.

Cheese is pressed through many stages of the cheese-making process, and the liquid by-product that comes from this pressing process is called whey.

This liquid whey is then dehydrated into powder, which is done through various low-temperature and ultra-filtration stages, and the end result is whey protein powder.

Usually, on the first filtration will result in Whey Protein Concentrate (WPC), and any additional filtration can result in a finer, pure protein extraction with fewer sugars known as Whey Protein Isolate (WPI).

Of course, this is an oversimplification of whey processing, but this gives you an idea of where whey actually comes from.

Not All Whey Protein is Created Equal

When it comes to buying cheap whey protein, you will generally compromise on raw ingredient quality, questionable ingredients, poor quality whey and protein content.

Let’s break these down further to give you an understanding of what these areas of purchasing mean.

Raw Ingredient Quality

When purchasing a cheaper whey protein, the ingredients may be sourced from cheaper ingredient suppliers. 

Although this is good for the cost of the product from a manufacturing perspective, This could lead to ingredients that contain traces of harmful compounds, such as pesticides, or whey sourced from cows raised in less-than-ideal environments or poor diet regimes.

Questionable Ingredients

Sometimes, cheaper protein powders contain questionable, or more so, unnecessary ingredients that could impact your health.

Some ingredients include artificial sweeteners (such as sucralose) or an array of thickeners (such as guar gum) that alter the flavour or texture of the end product.

Although these again significantly lower the cost of producing the product, some of these compounds can have a negative impact on our health.

Some studies have begun to show changes in the human gut microbiota on supplementation of sucralose (del Pozo et al., 2022), and others may even suggest sucralose’s ability to decrease insulin sensitivity, reducing our ability to process sugars in the body (Romo-Romo et al., 2018).

Poor Quality Whey

This one loops back to our first point slightly, but we’ll go into a little further detail.

Purchasing a whey protein powder with good quality whey will tend to be sourced from pasture-raised cattle, which is better described by a more common phrase known as Grass fed whey.

Grass-fed whey contains practically zero harmful ingredients (such as antibiotics) and contains a higher quality amino acid profile, including higher levels of Branched Chain Amino Acids (BCAAs) than regular whey proteins.

Protein Content

Most cheaper whey products tend to have a lower protein per serve content, which is often due to the quality of whey paired with added sugars and flavouring.

When looking for a higher quality whey protein powder, look at how many serves you get from the tub. Most cheaper whey products will sit under the 24g per serve mark, whereas higher quality will sit higher.

Tips on Buying Whey Protein

Of course, we can’t all afford premium quality whey protein, and sometimes it’s okay to compromise on some of the above to fit supplements into your budget.

That being said though, here are some tips to use when shopping for your next whey protein powder.

  • Look at the protein per serve – A good quality whey protein will be higher than 24g per serve, giving you more bang for your buck.
  • Avoid artificial sweeteners (if you can) – Most cheaper protein powders will use artificial sweeteners such as sucralose, this drastically lowers the cost but could be harmful long term.
  • Study the label – It’s always best to check the label and most importantly, the ingredients used before buying. Most companies will disclose if they use high-quality ingredients, and do not always state grass-fed (due to Australian labelling laws). 
  • Check the brand’s website – Things that usually can’t be disclosed on the label will end up on the company website, so it this always good to check if the label isn’t hitting the mark.

Taste it first – Always jump at the opportunity to sample a product first before buying. Most premium whey proteins aren’t overly sweet, and this is due to using less sweetener and keeping more of the protein content in the formula.

The Brand I Recommend

One company that I recommend for high-quality, premium-grade whey protein is UM Sports.

Full disclosure, I am affiliated with this brand and manage the operations and formulation of everything that goes on in the background.

But… This is why I recommend it because I know what goes in. UM Sports uses only Grass-fed premium Fonterra New Zealand-sourced whey, some of the highest-grade whey on the market.

On top of this, other key benefits of UM Sports include:

  • 100% use of Natural Sweeteners in all UM Sports labelled products.
  • Gluten-free tested and labelled.
  • Manufactured and produced in Queensland, Australia.
  • Tried and tested formulas for over 15 years, used by world-class bodybuilders and sports athletes.

UM Sports also do a clean Whey Protein Isolate Flavoured and Whey Protein Isolate Natural!


When it comes to buying whey protein, it can be challenging due to the sheer overwhelm of whey products that fill the shelves.

To reduce overwhelm, always take your time and consider the ingredient quality, protein content and ingredients used in all formulas.

Using the tips provided above, you can begin to find the protein powder that works for you. If you want to jump the gun and try a premium whey protein that ticks all the boxes, I highly recommend UM Sports Platinum Blend or UM Sports Whey Protein Isolate.
