What's the Difference Between Protein Powders?
With so many protein powders available, choosing the right one can feel overwhelming. The good news? Each type has its own strengths.
- Whey Protein Concentrate (WPC): Our most popular all-rounder, offering excellent value, great taste, and high protein.
- Whey Protein Isolate (WPI): The highest protein per serve, with very low levels of carbohydrates, fat, and lactose.
- Protein Matrix+: A multi-source protein blend offering great value for money, with a smooth, creamy texture and added lactase enzyme to support easier digestion.
- Plant-Based Proteins: Earth Protein, Pea Protein, Soy Protein, and Rice Protein provide dairy-free and vegan-friendly alternatives.
- Micellar Casein: A slower-digesting protein that's popular before bed or between meals.
- Protein Water: A light, refreshing alternative to traditional protein shakes.
- Collagen Protein: A specialised protein for those looking beyond traditional whey or plant-based options.
- Muscle Food 101: A protein and carbohydrate blend designed for those looking to increase their calorie intake.
There isn't one "best" protein powder - only the best protein powder for your goals, diet, and lifestyle.
How to Choose the Best Protein Powder
The best protein powder depends on what you need it to do.
The Best Value Protein Powder
Choose Whey Protein Concentrate if you want a cost-effective, high-protein option for everyday use.
WPC is a great starting point for most customers who tolerate dairy and want reliable protein without overcomplicating the choice.
The Best Lean Protein Powder
Choose Whey Protein Isolate if you want a higher-protein, lower-lactose option with minimal fats and carbohydrates.
WPI is popular with customers who want a cleaner macro profile or a lighter whey protein shake.
The Best Vegan or Dairy-Free Protein Powder
Choose Earth Protein, Pea Protein, Soy Protein Isolate or Rice Protein Isolate if you avoid dairy or follow a vegan diet.
These options make it easier to increase protein intake without relying on whey.
The Best Natural Protein Powder
Choose Natural WPC, Natural WPI or selected plant proteins if you want a protein powder with no artificial flavours or sweeteners.
These are a good fit for customers who prefer a simpler ingredient profile.
The Best Weight Management Protein Powder
Choose a high-protein option that helps you meet your protein intake while fitting your daily calories.
Thermowhey, Protein Balance, WPI, Protein Bars and selected plant-based proteins can all fit into different weight management routines, depending on your diet and preferences.
The Best Mass Gainer Protein Powder
Choose protein powders that help you reach your daily protein and calorie targets.
WPC , WPI, Protein Matrix+, Muscle Food 101 and Micellar Casein can all play a role depending on whether you need a lean protein top-up or extra calories.

How to Use Protein Powder
Protein powder is easy to use: add water or milk to a shaker, add your protein powder, shake well and drink.
You can also add protein powder to:
- Smoothies
- Oats
- Yoghurt
- Pancake mixes
- Baking recipes
- High-protein snacks
The amount of water or milk is flexible. Use less liquid for a thicker, sweeter shake, or more liquid for a lighter drink.
When to Take Protein Powder
Protein powder can be taken at any time of day.
Many customers use it:
- After training
- Between meals
- With breakfast
- As a snack
- To top up a low-protein meal
- Before bed, especially with casein
Post-workout is a popular time, but the bigger picture is your total daily protein intake. Timing helps, but consistency does the heavy lifting.
