Applied Nutrition is one of those UK brands that flies under the radar. While everyone talks about Optimum Nutrition and MyProtein, Applied Nutrition quietly delivers some of the best value supplements on the market. Their Critical Whey is a prime example.
I picked this up on a whim because it was on offer at the time, expecting it to be average. It was not. Here is my honest review after using it properly.

About Applied Nutrition
Applied Nutrition is a UK-based supplement company founded in 2014. Despite being younger than giants like ON or MyProtein, they have built a solid reputation in the UK fitness scene. You will find their products in most UK supplement shops and they sponsor several professional athletes. Being UK-based means they understand the local market and price their products competitively.
Nutritional Breakdown
| Per 30g Serving | Amount |
|---|---|
| Calories | 118 kcal |
| Protein | 22g |
| Carbohydrates | 2.5g |
| Fat | 2.1g |
| Sugar | 2.1g |
That gives you a protein ratio of around 73%, which is standard for a whey concentrate product. It is not as high as ON Gold Standard (80%), but for the price difference it is perfectly acceptable.
My Personal Experience
Taste
I went with Chocolate flavour and was genuinely impressed. It is not as rich as ON Double Rich Chocolate, but it is smooth, pleasant, and not overly sweet. Some budget proteins have that fake, chemical aftertaste — Critical Whey does not have that at all.
It tastes like a decent chocolate milkshake. Nothing fancy, nothing offensive. For a protein you are drinking every single day, that is exactly what you want.
Mixability
Good but not perfect. With a shaker and cold water it mixes well — maybe 10-15 seconds of shaking. Occasionally you get a tiny bit of residue at the bottom, but nothing like the clumpy mess you get with some cheap proteins. It is slightly thicker in consistency than ON Gold Standard, which some people actually prefer.
Digestion
No issues for me personally. Being a whey concentrate, it does contain more lactose than isolate-based products, so if you are particularly sensitive to dairy you might want to try a small tub first. For most people though, it should be absolutely fine.
The Real Test: Would I Buy It Again?
Yes. And here is why — the price-to-quality ratio is the best I have found in the UK market. You are getting solid protein from a reputable UK brand at a price that is genuinely hard to beat. Is it as premium as Gold Standard? No. But it is 70-80% as good at 60-70% of the price, and for most people that maths makes a lot more sense.
Available Sizes and UK Prices
| Size | Servings | Approx Price | Price Per Serving |
|---|---|---|---|
| 450g | 15 | £10-13 | £0.67-0.87 |
| 900g | 30 | £18-22 | £0.60-0.73 |
| 2.27kg | 75 | £35-42 | £0.47-0.56 |
Look at those prices per serving compared to ON Gold Standard. At the 2.27kg size, you are paying roughly £0.50 per serving versus £0.70+ for Gold Standard. Over a year of daily shakes, that saving adds up to over £70.
Pros and Cons
What I Like
- Outstanding value for money — one of the cheapest quality proteins in UK
- Solid taste with no chemical aftertaste
- UK brand with good quality control
- Widely available in UK supplement shops and Amazon
- Good flavour range including Chocolate, Vanilla, Strawberry
- Mixes well with just a basic shaker
- 22g protein per serving is respectable
What I Do Not Like
- Slightly thicker consistency than premium proteins
- Whey concentrate only — no isolate in the blend
- Protein ratio (73%) is lower than isolate-based products
- Not as many flavour options as ON or MyProtein
- Less well-known brand so fewer independent reviews available
Applied Nutrition vs The Competition
| Product | Protein/Serving | Price/kg | Type | Best For |
|---|---|---|---|---|
| Applied Nutrition Critical Whey | 22g | ~£18-22 | Concentrate | Best value |
| ON Gold Standard | 24g | ~£28-30 | Isolate blend | Premium quality |
| MyProtein Impact Whey | 21g | ~£15-20 | Concentrate | Cheapest (on sale) |
| Bulk Pure Whey | 22g | ~£18-24 | Concentrate | Clean ingredients |
Applied Nutrition sits in the sweet spot between premium and budget. It is consistently priced (unlike MyProtein which varies wildly depending on sales), and the quality is reliable.

Who Should Buy Applied Nutrition Critical Whey?
Buy it if:
- You want quality protein without paying premium prices

- You are a beginner and do not want to overspend on your first protein
- You want consistent pricing (not dependent on sales like MyProtein)

Frequently Asked Questions
Is Applied Nutrition a good brand?
Yes. They are a legitimate UK supplement company with proper manufacturing standards and a growing reputation. They are not as established as ON or MyProtein, but the product quality is solid and consistent.
What is the best flavour of Critical Whey?
Chocolate is the safest bet and the one I personally recommend. Vanilla is also solid. I have not tried all flavours but the popular ones are reliable.
Is it good for building muscle?
Yes. 22g of protein per serving is more than adequate. Muscle building comes from total daily protein intake and progressive training — the brand of protein you use makes virtually no difference to your results.
Applied Nutrition vs Optimum Nutrition — which is better?
ON Gold Standard is objectively the better product in terms of protein content, mixability, and taste. But Applied Nutrition is significantly cheaper. If budget matters, Applied Nutrition gives you 90% of the results at 70% of the price. I have used both and built the same amount of muscle on either. Read my full ON Gold Standard review for a detailed comparison.
Can I use it for baking or smoothies?
Absolutely. The Chocolate and Vanilla flavours work well in protein pancakes, smoothies, overnight oats, and baking. The slightly thicker consistency actually works in your favour for thicker smoothies.
Final Verdict: 8.5/10
Applied Nutrition Critical Whey is the best value protein powder I have found in the UK. It does not have the premium feel of Gold Standard, but it delivers where it counts — decent protein content, good taste, and a price that will not hurt your wallet.
If you are spending your own money and want honest value, this is the protein I would point you towards. It is exactly what I wish someone had recommended to me when I first started training and was wasting money on overpriced supplements.
