Adding extra dietary protein has benefits for gym-goers wishing to build, maintain and repair muscle mass, but it’s also a smart option for a filling, healthy snack for weight loss for both men and women.

We all have different goals when it comes to our health and fitness, so it’s important you choose the right whey protein for your lifestyle. In this article, we’ll examine ingredients, shed some light on isolates and BCAA’s, and hopefully find your flavour amongst our top picks in the UK from Amazon. Time to get strong!

How to Choose Whey Protein in the UK

In order to find the best whey protein for your needs, you’ll need to assess your goals and choose a powder with the appropriate nutritional profile, as well as making sure you get the right size delivered to your door. Here are our top tips to get you started.

1

Understand Which Type of Protein Is Best For You

Understand Which Type of Protein Is Best For You

There are three main types of whey protein: whey concentrate, isolate and diet whey. We'll explain the options available so you can pick the one that enables you to conquer your goals.

Standard Whey Protein Is Cheaper, Whey Isolate Is More Digestible

The most readily available protein will be labelled as straight-up whey protein, and is a blend of proteins taken from the liquid part of milk as well as various flavourings. They’re usually the most affordable, but they can range from budget to expensive depending on the brand and quality.

Whey isolate is a more processed form of milk protein, that has literally been isolated from the other components it contains, namely the fats and sugars. This purer form will usually be more expensive, however those looking to lose fat and lean out may find it appealing as it is by default lower in fats, carbs, and calories.


Isolate is also lower in lactose, the enzyme found in dairy products that some people are intolerant or sensitive to. Therefore, whey isolate may be a good choice for those who want maximum digestibility, although some standard whey proteins do feature added enzymes that aid in digestion.

Diet Whey: Added Ingredients, Beneficial to Weight Loss

Proteins labelled as diet whey usually contain a slew of other ingredients alongside whey protein, such as carbohydrates, caffeine sources such as green tea extract, and the usual flavourings and sweeteners. This variety is a tool for weight loss and can be implemented as part of a low-calorie diet.

On the other hand, some fitness buffs believe sticking to a purer protein with ingredients you can recognise and eating a wholesome diet is the best and healthiest way to lose weight, but it’s up to you to decide which camp you fall in when it comes to these additives.


Bulk up your protein intake with protein bars or vegan protein bars.

Check the Ingredients to Get the Protein, Calories and Amino Acids You Need

Check the Ingredients to Get the Protein, Calories and Amino Acids You Need

A bodybuilder wanting to gain sizeable muscle mass won’t have the same nutritional needs as someone wanting to tone up or supplement protein as part of a busy lifestyle, so it’s important you find out what's inside your whey protein before you buy.

More Grams of Protein Per Serving Are Better for an Active Lifestyle

In terms of gaining mass, the more grams you see on the label, the better. There are specific mass building powders available with a very high protein content of around 80-90%, which will make it easier to eat 50g or more if that’s your goal.

Otherwise, the average gym-goer or active type who requires whey for building and repairing muscle and staying on top of their protein intake will find a 20-30g content sufficient. Isolate is usually higher in protein than standard whey, but only by a few grams. 


If you prefer a plant-based protein product, consider vegan protein powders.

Note the Amount of Fat, Carbs, Sugar and Calories

Whey powder contains 80-90% protein, with the macronutrients fat and sugar making up the remaining 10-20%. If you’re on a weight loss journey or counting your macros, you may want to choose a whey protein with low amounts of sugar, carbohydrates and fat

Even if you’re not looking to shed the pounds, a healthy whey should contain at most 3g of carbs with 2 of those from sugars, and only 1 or 2 grams of fat. Some will contain real sugar, but usually artificial or natural sweeteners to keep the calories down. 


A calorie content of 150Kcal per 25g of protein (which is also approximately a serving size) is considered a good ratio for supplementing the growth and repair of muscle after exercise whilst dropping fat, so check the label for a figure around this size. You may want to go lower if weight loss is your main priority, though.

Does It Have the Right BCAA’s for Muscle Growth and Preventing DOMS?

There are 9 branched-chain amino acids (BCAA’s) that the body does not produce on its own, and should therefore be included in our diet. Three of them occur naturally in protein-rich foods such as dairy and whey lend a hand in the growth of muscle and the reduction of DOMS (delayed onset muscle soreness) which we could all do without!

So, it’s safe to say that a whey protein with a good amount of these BCAA’s is going to benefit not only our wellbeing, but our performance too. Make sure the protein mentions BCAA’s on the label, and look for around 5 grams.

Diet Whey For Everyone, Minus the Additives

Pro: value for money, natural | Con: does not mix well with water

TPW prove that diet whey doesn’t have to mean a chalky protein powder full of rubbish additives and fillers. It’s one of the lowest on our list in terms of calories and carbs and is very natural, with the 90 from the name denoting the protein percentage of the isolate.


Reviews go so far as to say it’s “Heaven in a cup”, and actually, they are spot on! There are sizes available from 500g up to 4kg, so you can treat yourself to a few of the tempting flavours or stock up on a large tub for a good price. Yum!

Pro: moderate carbs and sugars | Con: contains allergens

Bringing to the table 24g of pure whey protein that has been thoughtfully instantised for zero chance of lumps, ON’s Gold Standard definitely lives up to its namesake.


Containing 5.5g of BCAA’s and only moderate carbs and sugars, it’s the perfect whey for fitness and nutrition enthusiasts of every ilk. Choose from several flavours including banana cream and rocky road, and reap the rewards of this awesome product.

From blueberry cheesecake to tiramisu and cinnamon danish, if you’ve got a sweet tooth that needs a healthy fix, MyProtein are your saving grace. They’re extremely popular for a reason, and have simple but effective ingredients that will help to build lean muscle mass.


The super smooth formula is also a match when it comes to baking with your whey, and is low in fat, carbs and sugars so you can chow down on your creations guilt-free.

Natural Whey and Isolate Blend With Digestive Enzymes

Pro: no sweetener added, no sugar | Con: somewhat bland taste

An excellent pick for those who weight train whether light or heavy, active types or those who want a clump-free whey based on natural ingredients. A digestive enzyme complex is also added that makes it simple to digest, even for sensitive tums.


The protein is derived from the milk of only grass-fed cows, which is richer in omega-3 fatty acids that are beneficial to overall health and can aid in fat loss. It’s also pretty good value, and will last you a while if you have one after a few sessions a week.

Basic Whey in Tasty Flavours for Any Time of Day

Pro: unflavoured option available | Con: low protein content 

Whilst the protein content is on the lower end of the recommendation, this does mean it’s a sound option for drinking throughout the day if you’re upping your intake or need a helping hand with weight loss. The specs are good too, and each shake is only 100 calories.


Where The Protein Works really excel is in their flavours, the likes of which have even won awards. Millionaire’s shortbread anyone? Or, there is an unflavoured option if you prefer.

High Calorie and Protein for Weight Gain

Pro: best for home use | Con: may be a sickly flavour to some

Whether it’s bulking season, you train intensely or you’re trying to gain some weight, ON’s coveted mass gainer delivers the results with added carbohydrate powder, a high calorie formula and 50 grams of protein.


As it is recommended that you use a blender and add other calorie-dense foods for best results, it is perhaps best for use at home. Or if not, remember to prep a shake before you head to the gym. You will need to take a lot of this as well in order to get the best results.

Brilliant Value and Great Tasting Whey

Pro: great taste, smaller pack size available | Con: sweetener used is hard to digest for some

Perhaps one of the most value for money whey proteins available, this standard whey would be a great starter protein with the 1kg option too. Each serving provides 23g of protein, and it’s highly rated for its great taste whether you opt for strawberry, chocolate or vanilla.


The sweetener Sucralose is used which some people find hard to digest, but the rest of the ingredients are few and natural, so it gets our vote nonetheless.

Clean and Digestion-Friendly Unflavoured Whey

Pro: digestion-friendly, great for casual consumption | Con: small packet, runs out quickly

If you’re after the cleanest and most natural whey for baking or boosting your intake, look no further. You have to be willing to pay for it, but this whey isolate is 92% of pure, grass-fed, hormone-free protein with absolutely no sugars or sweeteners.


It’s also very easy to digest, low in fats and calories, and is naturally high in BCAA’s. It doesn't come in the biggest packets, so you might have to buy more than one if you want to stock up.

Extreme Protein for Extreme Gains

Pro: contains performance-enhancing enzymes | Con: high price point

Definitely one for the mass gainers, popular brand Reflex’s One Stop Xtreme lives up to the name, supplying your muscles with an impressive 55g of protein and 10g of BCAA’s per daily serving. The carbs and cals are high, but that’s what’s going to give you those gains!


Again the ingredients list is very long, but there’s nothing artificial and 17 added vitamins, performance enhancing creatine and digestive enzymes are among them. It’s expensive though, and probably only worth it if you’re a dedicated lifter.

Low Calorie Whey With Added Nutrition

Pro: contains green tea extracts, fatty acids | Con: added sweeteners

At only 91 calories per serving and with low carbs and fat, this diet shake will help your body refuel and stay lean. The protein is low, but you may take a double serving after weight training.


The whey is blended with soy, flax and barley for a rounded nutritional profile, as well as including added green tea extracts and fatty acids to kick start the metabolism. On the other hand there are a lot of ingredients and added sweeteners, which do make us question how good for us it really is.

Frequently Asked Questions

Frequently Asked Questions

Can You Have Whey Protein Everyday?

Whey protein is generally well tolerated, so it’s perfectly fine for you to consume it every day. That said, most of us tend to get all the protein we need from our regular diets. Nevertheless, it is a quicker and somewhat cheaper alternative if needs be but it should be paired with a healthy diet.

When Should You Take Whey Protein?

This is largely down to personal preference, but if you are seeking the benefits alongside a workout regime, then taking the protein before or a little after exercising seems to harbour the most benefits. Whey protein is also great if you’re short on time for breakfast, or need a snack during the day too. 

Can I Drink Whey Protein Without Exercise?

Yes, you may drink whey protein without exercising because regardless of whether your protein source is from a supplement or actual food, it will have the same effect on your body. However, you should always keep in mind that this must be balanced out with a healthy diet of other macronutrients.

Summary

Match the whey protein type and its nutritional profile to the needs of your exercise routine, dietary goals and ingredient preferences and you’ll be on your way to a healthy body inside and out. Hopefully you’ve learnt a thing or two from our guide and have managed to find the shake to get you closer to your fitness goals.
