02 Sep How to Choose the Right Protein Powder for You

Protein powder isn’t just for bodybuilders anymore. It’s become a popular choice for anyone who wants to gain muscle, manage their weight, or stay fuller for longer. Whether you’re looking to support muscle recovery after a workout or simply want to increase your daily protein intake, a clean protein powder can be a convenient way to support your nutrition and health goals. 

But with endless options on the shelf, choosing the right one can feel like a workout in itself. Whey or plant? Isolate or concentrate? And where does collagen fit in? Our simple guide is here to help you find a protein powder that fits your lifestyle and your goals. 

Why is clean protein powder important? 

When choosing a protein powder, it’s easy to focus on the number of grams of protein per serving and overlook everything else in the tub. But the quality of the ingredients matters too. 

In 2025, the US-based Clean Label Project tested top-selling protein powders and found that many of them contained heavy metals and bisphenol A (which is used to make plastic). These ingredients are also linked to increased cancer risk and other health concerns. 

That doesn’t mean every protein powder is a problem. But it does highlight why it’s important to pay attention to what else is in your protein powder. A clean protein powder should provide a good source of protein without relying on unnecessary fillers, excessive added sugar, or ingredients that don’t add nutritional value. 

A high-quality protein powder can help you:

• Support muscle growth and recovery: Protein provides the amino acids your body needs to repair and build muscle, making it ideal if you exercise regularly. 
• Maintain lean muscle: Protein is important for maintaining muscle, especially when you’re active or working towards a weight-management goal. 
• Meet your daily protein needs: Adding a scoop of protein powder to a smoothie or overnight oats makes it easier to increase your protein intake.  
• Stay fuller for longer: Protein is more satiating than carbohydrates, so adding protein to your breakfast or midday snack can help keep hunger at bay. 

Whey vs plant vs collagen protein: what’s the difference?

When it comes to choosing the best protein powder for you, three of the most popular options are whey protein, plant-based protein, and collagen protein. While they can all have a place in a healthy lifestyle, they’re not interchangeable. They come from different sources, have different amino-acid profiles, and are suited to different goals. 

Whey protein: great for muscle growth and recovery  

Whey protein comes from milk and is a complete protein, meaning it naturally contains all nine essential amino acids your body needs. It’s a popular choice for muscle growth, muscle recovery, and post-workout nutrition because it provides a concentrated source of protein that’s easy to add to shakes and smoothies. 

You’ll generally find two main types: whey concentrate and whey isolate. Whey concentrate contains some naturally occurring fat and lactose, while whey isolate is more highly filtered and typically contains a higher percentage of protein with less fat and lactose. 

Whey could be for you if: You eat dairy and want a complete protein that’s particularly suited to muscle building, workout recovery, and post-workout nutrition. 

Plant-based protein: a dairy-free, plant-powered option 

Plant protein comes from sources like peas, rice, and hemp, making it a popular choice for anyone following a vegan, vegetarian, or dairy-free diet. Different plant proteins have different amino-acid profiles, which is why many vegan protein powders combine sources like pea and rice protein to provide a more complete amino-acid profile.

Plant protein can be a great everyday option if you want to increase your protein intake without using dairy. Hemp protein can also provide additional nutrients like fibre and healthy fats, depending on the product.

Plant protein could be for you if: You’re vegan, vegetarian, or lactose intolerant, or simply prefer to get your protein from plant sources. 

Collagen protein: targeted support for skin and joints 

Collagen protein works a little differently from whey and plant protein. Collagen peptides are rich in amino acids like glycine and proline and are commonly taken to support skin health, joints, bones, and connective tissue.

Collagen isn’t a complete protein because it doesn’t contain all nine essential amino acids in the amounts your body needs. This means it’s better viewed as a targeted supplement for collagen support rather than your main source of dietary protein. 

Collagen could be for you if: Your main focus is supporting skin, joints, and connective tissue rather than using a protein powder primarily to meet your daily protein needs. 

Comparing whey, plant, and collagen proteins: 

Protein type	Best for	Complete protein?	Dairy-free?	Plant-based?
Whey Isolate	Muscle building, recovery & high-protein diets	Yes	No	No
Whey Concentrate	Everyday protein & general fitness	Yes	No	No
Plant Protein	Vegan, dairy-free diets & everyday protein	Depends on the blend	Yes	Yes
Collagen	Skin, joints & connective tissue support	No	Usually no*	No*

*Most traditional collagen is bovine or marine-derived, although vegan collagen-support products are available at Faithful to Nature. 

Vegan but interested in collagen? Meet Vollagen™

If you follow a vegan or strict vegetarian diet, The Harvest Table Vegan Vollagen™ Powder offers a plant-based alternative. With a base of pea protein and brown rice protein, Vollagen™ combines plant-based protein with The Harvest Table’s trademarked CollaV blend. Made from natural plant sources, CollaV contains glycine and proline, along with bamboo silica. 

Vegan Vollagen™ Powder provides a complete amino-acid profile while supporting your skin, hair, nails, joints, ligaments, and gut lining. This makes it a great option if you want to combine plant-based protein with collagen support in one product, without using animal-derived collagen. 

It’s also easy to work into your everyday routine and can be added to smoothies and shakes, or used in cooking and baking.

What should you look for when choosing a protein powder?

The right protein powder needs to work for real life, too. Think about your diet, activity level, ingredients, taste, and how easily it fits into your daily routine. 

• A quality protein source: Look for protein from sources that suit your diet and preferences, whether that’s whey, pea, rice, hemp, or another quality source.
• A simple ingredient list: Fewer unnecessary ingredients can make it easier to know exactly what you’re putting into your body.
• A protein content that suits your needs: Check how much protein you’re actually getting per serving, rather than relying on the front-of-pack claims.
• Ingredients that fit your lifestyle: If you’re vegan, dairy-free, or have specific dietary preferences, check the full ingredient list to make sure the product works for you.
• A flavour and format you’ll actually enjoy: The best protein powder is one you’ll use consistently, whether that’s blended into a smoothie, stirred into oats, or added to your post-workout shake.

Our verdict: which protein powder should you choose?

There isn’t one protein powder that’s best for everyone. The right choice depends on what you’re trying to achieve, what you eat, and what you’ll actually enjoy using. 

Match the protein powder to your goal, rather than simply choosing the one with the biggest tub or the trendiest label.

If you’re focused on muscle building and recovery, whey isolate is a strong choice. For a simple everyday protein boost, whey concentrate can be a practical option. If you avoid dairy or follow a vegan diet, look for a quality plant protein blend. And if your priority is skin and joint support, collagen offers a more targeted approach.

For vegans who want both everyday plant-based protein and collagen support, Vollagen™ offers an alternative that combines the two in one formula.

Ultimately, the best protein powder is the one that fits naturally into your lifestyle and helps you consistently meet your nutrition goals.

How to get the most from your protein powder

Protein powder works best as part of a balanced diet, not as a replacement for whole-food protein.

Try adding it to:

• Smoothies with fruit, nut butter, and milk or a plant-based alternative
• Overnight oats or porridge
• Yoghurt or chia pudding
• Pancakes and healthy baking
• Post-workout shakes
• Breakfast bowls

And remember, more protein isn’t automatically better. Your total daily protein needs depend on factors like your body size, activity level, age, and goals. A protein powder is simply a convenient way to help you reach an appropriate intake.

Q: What is the difference between whey isolate and whey concentrate?
A: Whey concentrate is less processed and retains some naturally occurring fat and lactose, making it a practical everyday option. Whey isolate is more highly filtered, resulting in a higher protein percentage per serving with less fat and lactose. If you are sensitive to lactose or want a leaner protein source, isolate is generally the better choice.

Q: Is plant protein as effective as whey for building muscle?
A: Research suggests high-quality plant protein blends, particularly pea and rice combinations, can support muscle growth comparably to whey when consumed in adequate amounts. Whey has a slight edge in leucine content, the amino acid most directly linked to muscle protein synthesis, but the practical difference for most people is modest, especially with consistent training and sufficient total protein intake.

Q: Can I use protein powder if I am lactose intolerant?
A: Yes. Whey isolate is lower in lactose than whey concentrate and is tolerated by many people with mild sensitivity. Plant-based protein powders from pea, rice, or hemp are completely dairy-free and naturally lactose-free, making them the cleaner option for anyone who is strictly dairy-free or highly sensitive to lactose. Browse our protein powders for women for curated options across both categories.

Q: What makes a protein powder “clean”?
A: A clean protein powder provides a quality protein source without unnecessary fillers, excessive added sugar, artificial flavours, colours, or preservatives. Independent testing has found that some popular protein powders contain heavy metals and plasticisers, which is why checking the ingredient list and choosing transparent brands matters. Every product at Faithful to Nature is screened against a strict Ingredient Policy before it is stocked.
