The Complete Guide to Protein Powder: Which Protein Is Right for You?

Protein powder is one of the most popular supplements in sports nutrition — and for good reason.

Whether you're trying to build muscle, improve recovery, increase your daily protein intake, support a fat-loss phase or simply make hitting your nutrition goals easier, protein powder can be a convenient addition to your diet.

The difficult part is choosing the right one.

Whey concentrate, whey isolate, hydrolysed whey, plant-based protein, collagen, casein, protein water and mass gainers can all serve different purposes.

In this guide, we'll break down the different types of protein powder, what they do and how to choose the best option for your goals.

What Is Protein?

Protein is one of the three major macronutrients, alongside carbohydrates and fats.

It is made up of amino acids, which your body uses to build, repair and maintain tissues throughout the body.

Protein plays an important role in:

• Building and maintaining muscle

• Exercise recovery

• Supporting healthy bones and connective tissue

• Producing enzymes and hormones

• Maintaining everyday body functions

• Helping you feel fuller as part of a balanced diet

People who train regularly generally have greater protein requirements than people who are less active.

Whole foods such as meat, fish, eggs, dairy, legumes and other protein-rich foods should form the foundation of your diet, but protein powder can make reaching your daily protein target considerably easier.

What Is Protein Powder?

Protein powder is simply a concentrated source of dietary protein that can be mixed with water, milk or other foods.

Depending on the product, that protein may come from:

• Whey

• Milk

• Casein

• Peas

• Rice

• Other plant sources

• Collagen

Different processing methods create different types of protein powder, each with its own nutritional profile, texture, digestion characteristics and price point.

That is why there isn't one protein powder that is automatically best for everyone.

Your ideal protein will depend on your goals, diet, budget and personal preferences.

Benefits of Protein Powder

Protein powder isn't magic, but it can make good nutrition considerably more convenient.

It can help you:

Support Muscle Growth

Resistance training combined with adequate protein intake helps support the development and maintenance of muscle.

Improve Exercise Recovery

Training places stress on muscle tissue. Dietary protein provides amino acids that your body can use as part of the recovery and repair process.

Reach Your Daily Protein Target

Eating enough protein every day can sometimes be difficult, especially when you're busy.

A shake can provide a convenient protein source without requiring another full meal.

Maintain Muscle While Dieting

When you're consuming fewer calories, maintaining an adequate protein intake alongside resistance training can help support the preservation of lean muscle.

Stay Fuller Between Meals

Protein is generally more satiating than simply adding additional carbohydrate or fat calories, making protein-rich meals and snacks useful when managing overall food intake.

Add Protein to Everyday Foods

Protein powder doesn't need to be limited to shakes.

It can also be added to:

• Oats

• Smoothies

• Yoghurt

• Pancakes

• Baking

• Desserts

You can also explore our Protein Baking Mixes if you're looking for more convenient high-protein food options.

What Are the Different Types of Protein Powder?

There are now more protein options available than ever.

Here's how the major types compare.

Whey Protein Blends

Whey Protein Blends are one of the most popular choices for everyday protein supplementation.

Rather than using only one form of whey, a blend may combine different protein sources such as:

• Whey Protein Concentrate

• Whey Protein Isolate

• Whey Protein Hydrolysate

The exact combination varies between products.

Whey blends are popular because they can provide an excellent balance between protein content, flavour, texture and price.

Whey protein blends may suit:

• Everyday gym-goers

• Beginners

• Strength training

• Muscle-building phases

• Post-workout nutrition

• General daily protein intake

• Anyone wanting a versatile protein powder

If you're unsure where to start, a quality whey blend is often one of the easiest options.

Explore Whey Protein Blends.

Whey Protein Concentrate — WPC

Whey Protein Concentrate, commonly called WPC, is one of the most widely used forms of whey protein.

It contains complete dairy protein and naturally provides all nine essential amino acids.

Compared with whey isolate, concentrate generally retains slightly more naturally occurring carbohydrate, fat and lactose.

For many people, that's perfectly fine.

WPC is popular because it can offer:

• Quality complete protein

• Great taste

• Creamy texture

• Good mixability

• Excellent value

• A wide range of flavours

Whey concentrate may suit:

• Beginners

• Everyday gym-goers

• Muscle-building goals

• People wanting good value per serve

• Anyone without significant issues digesting dairy

For most people looking for an everyday protein powder, WPC can be an excellent choice.

Shop Whey Protein Concentrate.

Whey Protein Isolate — WPI

Whey Protein Isolate, commonly known as WPI, undergoes additional filtration compared with whey concentrate.

This generally results in a higher percentage of protein while reducing the amount of carbohydrate, fat and lactose in the final product.

That makes isolate popular among people who want a leaner nutritional profile.

Whey isolate may suit:

• Lean muscle goals

• Body composition phases

• People monitoring carbohydrate or fat intake

• Athletes

• People wanting a higher protein percentage

• Some people who prefer a lower-lactose whey option

It's important to remember that whey isolate isn't automatically "better" than concentrate.

It is simply a different type of protein.

If a whey concentrate fits your calories, digestion, budget and protein requirements, there may be no reason to switch.

Explore Whey Protein Isolate.

Whey Protein Hydrolysate

Whey Hydrolysate is whey protein that has undergone additional processing to partially break the protein into smaller peptide chains.

You'll often see it described as hydrolysed whey protein.

Hydrolysed whey products are generally positioned as highly refined protein options and are popular with athletes and serious trainers.

Whey hydrolysate may suit:

• Athletes

• High-volume training

• Post-workout nutrition

• People looking for highly processed whey formulas

• Those comparing premium whey options

Hydrolysed whey is generally more expensive than standard whey concentrate, so whether it's worth choosing will depend on your budget and individual requirements.

Explore Whey Hydrolysate.

Plant Based Protein

You don't need dairy to increase your protein intake.

Plant Based Protein provides an alternative for people following vegan or plant-based diets, as well as anyone who simply prefers to avoid dairy.

Depending on the formula, plant proteins may use sources including:

• Pea protein

• Rice protein

• Blended plant proteins

Some formulas combine multiple plant protein sources to create a broader amino acid profile.

Plant based protein may suit:

• Vegan diets

• Vegetarian diets

• Dairy-free diets

• People avoiding whey

• Everyday protein supplementation

The most important factors are choosing a formula that fits your dietary requirements and ensuring your overall daily diet provides adequate protein and essential amino acids.

Explore Plant Based Protein.

Protein Water

Don't like thick or creamy protein shakes?

Protein Water offers a lighter alternative.

Rather than drinking like a traditional milkshake-style protein powder, protein water products are generally designed to create a refreshing, water-based drink.

This makes them particularly appealing during warmer weather or around training.

Protein water may suit:

• People who dislike creamy shakes

• Post-workout hydration routines

• Hot weather

• People wanting a refreshing protein option

• Anyone looking to increase protein without another milk-style drink

Explore Protein Water.

Casein Protein

Casein Protein is another dairy-derived protein, but it behaves differently from whey.

Casein forms a thicker mixture and is digested more gradually than whey protein.

For this reason, it is commonly used later in the day or before bed.

Casein may suit:

• Evening protein intake

• Before-bed shakes

• People wanting a thicker protein shake

• People looking for a slower-digesting dairy protein

• Anyone wanting more variety in their protein intake

You don't need casein specifically before bed, but it can be a convenient way to increase your total daily protein intake.

Explore Casein Protein.

Collagen Protein

Collagen Protein is different from traditional whey or plant-based protein.

Collagen contains a different amino acid profile and is commonly used by people looking to support their overall intake of collagen peptides.

Collagen is a major structural protein found throughout areas including:

• Skin

• Tendons

• Ligaments

• Cartilage

• Bones

• Connective tissue

However, collagen shouldn't necessarily be viewed as a direct replacement for a quality whey or plant protein when your primary goal is increasing high-quality dietary protein for muscle development.

Think of it as a different type of supplement serving a different purpose.

Explore Collagen Protein.

Mass and Weight Gainer Protein

If gaining body weight and consuming enough calories is difficult, a Mass & Weight Gainer may be worth considering.

Mass gainers generally combine protein with a significantly larger amount of carbohydrates and total calories than a standard protein powder.

They are designed to make increasing overall calorie intake easier.

Mass gainers may suit:

• Muscle-building phases

• Bulking

• Hard gainers

• People with high calorie requirements

• Athletes with demanding training schedules

• People who struggle to eat enough food

The key difference is that a mass gainer isn't simply "more protein."

It's generally designed to deliver more calories.

If you already consume enough calories through food, a regular protein powder may be all you need.

Explore Mass & Weight Gainer Protein.

Weight Loss Protein

Weight Loss Protein products are generally formulated for people focused on calorie control or body composition.

Protein itself doesn't automatically cause fat loss.

Fat loss ultimately requires an appropriate overall calorie intake.

However, consuming adequate protein during a calorie deficit can be useful for maintaining muscle and helping build filling meals and snacks.

Weight-loss focused protein products may also include different ingredients or nutritional profiles depending on the formula.

These products may suit:

• Calorie-controlled diets

• Body composition goals

• People looking for convenient higher-protein meals or snacks

Always compare the nutrition panel and ingredients rather than assuming a product will create weight loss simply because it's marketed as a "weight loss protein."

Explore Weight Loss Protein.

Which Protein Powder Is Best?

There isn't one universal "best protein powder."

The best protein powder is the one that suits your:

• Goal

• Diet

• Digestion

• Protein requirements

• Calorie requirements

• Taste preferences

• Budget

As a simple starting point:

Your Goal	Protein to Consider
Everyday protein intake	Whey Protein Blends
Value and everyday use	Whey Protein Concentrate
Higher protein, lower carbs and fat	Whey Protein Isolate
Highly refined whey	Whey Hydrolysate
Vegan or dairy-free	Plant Based Protein
Light and refreshing option	Protein Water
Evening protein	Casein Protein
Collagen supplementation	Collagen Protein
Increasing calories and body weight	Mass & Weight Gainer Protein
Calorie-controlled nutrition	Weight Loss Protein

If you're still unsure, start by browsing our complete Protein Powder range and compare the nutrition information of each product.

Whey Concentrate vs Whey Isolate: What's the Difference?

This is one of the most common questions people have when buying protein.

Both WPC and WPI come from whey.

The main difference is filtration.

Whey Protein Concentrate

Typically:

• Contains slightly more carbohydrate and fat

• Contains more naturally occurring lactose

• Has a creamy texture

• Is generally less expensive

• Provides high-quality complete protein

Whey Protein Isolate

Typically:

• Undergoes additional filtration

• Contains a higher percentage of protein

• Contains less carbohydrate and fat

• Contains less lactose

• Is generally more expensive

For most people, both are perfectly valid choices.

Choose Whey Protein Concentrate if you want an excellent everyday protein with good value.

Choose Whey Protein Isolate if you specifically prefer the leaner nutritional profile of WPI.

How Much Protein Do You Need Each Day?

Your protein requirements depend on factors including:

• Body weight

• Training volume

• Training type

• Age

• Overall calorie intake

• Muscle-building goals

• Whether you're dieting

• Your broader health and lifestyle

Someone who performs regular resistance training will generally have different protein requirements from someone who is largely sedentary.

Rather than focusing only on how many protein shakes you drink, think about your total daily protein intake from all foods and supplements combined.

Protein powder should supplement your diet — not replace a balanced diet.

If you want personalised nutrition advice or have specific medical or dietary requirements, speak with an accredited practising dietitian, sports dietitian or another appropriately qualified health professional.

How Much Protein Powder Should You Take?

There's no universal number of protein shakes that everyone needs each day.

Someone who obtains most of their protein through food may only use a protein shake occasionally.

Someone with higher requirements or a busy schedule might use protein powder more regularly.

A better question is:

How much protein am I already getting from my diet, and how much more do I need?

Use protein powder to conveniently fill the gap.

Always follow the serving directions on the individual product.

When Is the Best Time to Take Protein?

Protein can be consumed whenever it helps you meet your overall requirements.

Common times include:

• After training

• At breakfast

• Between meals

• In a smoothie

• Before bed

• As part of a snack

• Whenever your normal meals are low in protein

You don't need to panic about drinking a protein shake the second your workout finishes.

Your total daily intake and consistency over time are generally much more important than obsessing over a tiny post-workout window.

Should You Drink Protein Before or After Training?

Both can work.

If you've eaten a protein-containing meal relatively close to training, you may not need another protein shake before you start.

After training, a protein shake is simply an easy way to begin your next feeding opportunity.

For most people, convenience matters more than trying to perfectly time every gram of protein.

Can You Take Protein Powder Every Day?

Protein powder can be used regularly as part of a balanced diet.

The important distinction is that it should be viewed as a convenient food supplement, rather than something that needs to replace whole foods.

Your overall diet should still provide a variety of nutrient-dense foods.

If you have a medical condition, allergies or specific dietary requirements, seek appropriate professional advice before changing your diet or supplement routine.

Do You Need Protein Powder to Build Muscle?

No.

You can build muscle without ever using protein powder.

Protein powder is simply convenient.

If you can consistently consume enough protein from food, you don't necessarily need a supplement.

But for many people, preparing enough high-protein meals every day isn't always practical.

That's where protein powder becomes useful.

Does Protein Powder Make You Bulky?

No.

Protein powder doesn't automatically make someone bulky.

Increasing muscle mass requires appropriate resistance training, sufficient nutrition and time.

A protein shake is simply a source of protein.

This applies equally to men and women.

Is Protein Powder Only for Bodybuilders?

Definitely not.

Protein is important for everyone.

Protein powders are commonly used by:

• Gym-goers

• Athletes

• Runners

• Team-sport athletes

• Busy professionals

• People trying to increase protein intake

• People dieting

• People building muscle

• People simply wanting a convenient snack

You don't need to be a competitive bodybuilder to benefit from convenient dietary protein.

Is Protein Powder Good for Women?

Yes.

Women require dietary protein for the same fundamental reasons as men, including maintaining muscle and supporting normal body functions.

There is no special reason women need to avoid protein powder.

The appropriate amount depends on individual nutrition requirements rather than gender alone.

Is Plant Protein as Good as Whey?

Both can contribute to your daily protein intake.

Whey naturally provides a complete essential amino acid profile and is a particularly popular sports nutrition protein.

Plant-based proteins can also provide an effective protein source, particularly when formulas use complementary plant proteins or when the person's overall diet provides sufficient essential amino acids.

If you don't consume dairy or follow a vegan diet, Plant Based Protein can be a practical option.

Is Collagen the Same as Whey Protein?

No.

Whey and collagen have very different amino acid profiles.

Whey is commonly chosen as a complete dietary protein for supporting overall daily protein intake and muscle-related goals.

Collagen is commonly chosen for its particular collagen peptide profile and its role as a structural protein.

If your main goal is increasing high-quality dietary protein for training, whey or a suitable plant-based protein will generally serve a different role from Collagen Protein.

Should You Take Protein on Rest Days?

Yes — your body still requires protein on days you don't train.

Training stimulates adaptation, but recovery doesn't stop when you leave the gym.

Your protein target shouldn't suddenly disappear because it's Sunday and you aren't training.

Aim for consistent protein intake across your week.

Can Protein Powder Help With Weight Loss?

Protein powder doesn't directly burn body fat.

Fat loss requires an appropriate overall energy balance.

However, protein can play a useful role during a fat-loss phase because adequate protein intake can help support muscle maintenance and make it easier to build filling meals.

Protein powder can therefore be a convenient tool within an appropriately structured diet.

You can compare products in our Weight Loss Protein range.

Can Protein Powder Help You Gain Weight?

It can — but only if it contributes to consuming more energy than your body uses.

A regular protein shake may contain relatively few calories, so someone trying to significantly increase their calorie intake may prefer a Mass & Weight Gainer Protein.

These products generally combine protein with substantially more carbohydrates and calories than ordinary protein powders.

What Should You Mix Protein Powder With?

The simplest option is water.

You can also mix protein with:

• Milk

• Plant-based milk

• Smoothies

• Yoghurt

• Oats

• Cereal

• Pancakes

• Baking recipes

Using milk instead of water will generally increase the calories and nutritional content of the finished shake.

The right option depends on your goals.

What Should You Look for When Buying Protein Powder?

Don't choose a protein just because the label looks good.

Check the product carefully.

1. Protein Per Serve

Look at how much actual protein you're receiving per serving.

2. Serving Size

A product containing 25g of protein from a 30g scoop is very different from one requiring a much larger serving to deliver the same amount.

3. Protein Source

Check whether you're buying:

• WPC

• WPI

• Hydrolysed whey

• A whey blend

• Plant protein

• Casein

• Collagen

• Another protein source

4. Carbohydrate and Fat

This becomes particularly relevant if you're closely managing calories or macronutrients.

5. Ingredients

Read the full ingredient list, particularly if you have dietary preferences or allergies.

6. Flavour

A protein may have excellent nutritional numbers, but if you hate drinking it, you're unlikely to use it consistently.

7. Value Per Serve

Don't only compare the price of the tub.

Compare:

• Number of serves

• Protein per serve

• Total protein

• Serving size

• Product quality

The cheapest tub isn't necessarily the best value.

What Supplements Can You Take With Protein?

Protein powder doesn't need to be "stacked" with anything.

However, depending on your training goals, people commonly combine their protein routine with other supplements and gym essentials.

Creatine

Creatine is one of the most widely used sports nutrition supplements and can be taken independently of when you consume your protein shake.

Pre-Workout

A Pre Workout is typically used before training rather than as part of the protein shake itself.

Amino Acids

Depending on your training and nutrition preferences, you may also explore Amino Acids.

EAAs and BCAAs

Explore our EAAs & BCAAs range for additional amino acid products.

Healthy Snacks & Food

Protein doesn't always need to come from a shake.

Browse Healthy Snacks & Food for convenient nutrition options.

Gym Essentials

A quality shaker makes protein considerably easier to use while travelling, working or training.

Frequently Asked Questions About Protein Powder

What is the best protein powder for beginners?

For most beginners who consume dairy, a quality Whey Protein Blend or Whey Protein Concentrate is a straightforward place to start.

They provide complete protein and are available across a wide variety of flavours and price points.

What is the best protein for building muscle?

There isn't one special muscle-building protein.

Your overall protein intake, calorie intake and resistance training matter more than choosing one particular tub.

Whey concentrate, whey isolate and whey blends can all help contribute towards your protein requirements.

Explore our complete Protein Powder collection.

What is the best protein for getting lean?

Getting lean primarily depends on your overall calorie intake.

If you're looking for a protein with a high protein percentage and generally lower carbohydrate and fat content, Whey Protein Isolate is worth considering.

You can also explore Weight Loss Protein.

What's the difference between whey protein and whey isolate?

Whey protein concentrate and isolate both come from whey.

Isolate undergoes additional filtration and is generally higher in protein while containing lower levels of carbohydrate, fat and lactose.

Neither option is automatically better for everyone.

Is whey isolate lactose free?

Whey isolate generally contains less lactose than whey concentrate, but this doesn't automatically mean every whey isolate product is completely lactose free.

Always check the individual product label if lactose is a concern.

What protein should I use if I don't consume dairy?

Explore Plant Based Protein.

These formulas are designed for people seeking alternatives to dairy-based whey products.

What protein should I take before bed?

You don't need a special protein before sleeping.

However, Casein Protein is commonly used in the evening because of its slower digestion and thicker texture.

Can I use protein powder without exercising?

Yes.

Protein is an essential nutrient regardless of whether you exercise.

Your total requirements will vary depending on your lifestyle, activity level and individual circumstances.

Does protein powder damage your kidneys?

Protein powder isn't inherently harmful simply because it contains protein.

However, people with existing kidney disease, medical conditions or specific dietary restrictions should follow advice from their doctor or qualified healthcare professional regarding protein intake.

Can teenagers take protein powder?

Nutrition needs during adolescence can differ considerably between individuals.

Food should remain the priority, and parents or young athletes with questions about supplementation should speak with an appropriately qualified health professional or sports dietitian.

Can I have more than one protein shake per day?

How many shakes you need depends on how much protein you're already consuming through food.

There's little benefit in simply adding protein shakes without considering your total nutrition.

Use protein powder to help meet your requirements rather than treating a particular number of shakes as the goal.
