When it comes to boosting your protein intake, few supplements are as popular or as versatile as protein powder. But with so many types available, it can be hard to know which one is right for you. Whether you're looking to build muscle, recover faster, or simply hit your daily protein goals, understanding the differences between each type can help you make a smarter choice. For a sport-specific breakdown, see our guides on whey protein for runners and best supplements for CrossFit athletes.
Whey Protein Concentrate
All-round daily use and a budget-friendly protein option.
Creamy texture, around 70–80% protein, nutrient-rich and useful for muscle building and recovery.
Contains small amounts of lactose.
Whey Protein Isolate
Lean muscle goals, low-calorie diets or people wanting lower lactose.
90%+ protein, fast-digesting, low lactose and ideal as a post-workout protein.
Usually slightly more expensive and less creamy than concentrate.
Clear Whey Isolate
Anyone wanting a refreshing, juice-style alternative to a traditional protein shake.
Light and fruity, easy to digest, refreshing and made from a whey isolate base.
More processed and typically comes at a higher price point.
Plant-Based Protein
Vegan and dairy-free diets, or people with digestive sensitivities.
Pea protein is easy to digest, while hemp contains all nine essential amino acids. Both can support recovery and nutrition.
Can have slightly lower bioavailability than whey and may have earthier flavours.
Whey Protein Concentrate
Whey Protein Concentrate (WPC) is the most common and cost-effective form of whey protein. It's made from milk and typically contains around 70–80% protein, with the remainder made up of fats and carbohydrates.
Rich in essential amino acids, especially leucine, which supports muscle growth and recovery. It also retains more of the natural nutrients found in milk, giving it a creamier texture and taste.
Contains small amounts of lactose, which may cause discomfort for those with sensitivities.
Whey Protein Concentrate is ideal for most people looking for a well-rounded, budget-friendly option that supports muscle building and recovery.
We changed our well-loved Efectiv Whey, removed the skimmed milk powder, and it now consists of 100% whey protein concentrate.
Whey Protein Isolate
Whey Protein Isolate (WPI) goes through an additional filtration process to remove more fat, carbohydrates, and lactose, resulting in a product that's typically 90%+ pure protein. Not sure whether concentrate or isolate is right for you? Our whey isolate vs whey protein guide breaks down the key differences in detail.
Fast-digesting, low in lactose and leaner than concentrate. A strong option for post-workout recovery or people monitoring calorie intake.
Slightly more expensive and may lack some of the natural flavour and nutrients found in concentrate.
If you want a cleaner, more refined protein with minimal carbs and fats, Whey Protein Isolate is a great choice.
Clear Whey Isolate
Clear Whey Isolate offers a refreshing twist on traditional milky protein shakes. Made using the same isolate base, it's processed to remove the creamy texture, resulting in a light, juice-like drink.
Crisp, fruity flavours, easy to digest and ideal for people who dislike thick shakes or want a refreshing post-workout drink.
Typically more processed and can be pricier than standard whey.
Clear Whey Isolate is perfect for anyone wanting a lighter, refreshing way to boost protein intake without the heaviness of a standard shake.
Plant-Based Protein: Pea and Hemp
Plant-based protein powders are excellent alternatives for vegans, vegetarians, or those avoiding dairy. Two of the most popular sources are pea and hemp protein.
Made from yellow split peas, pea protein is rich in branched-chain amino acids and easy to digest. Its smooth texture and neutral flavour make it useful in shakes, smoothies and recipes.
Derived from hemp seeds, it contains all nine essential amino acids alongside omega-3 fatty acids and fibre. Its earthier flavour works particularly well in smoothies and baking.
While plant proteins generally have slightly lower bioavailability than whey, they're still highly effective for supporting muscle maintenance, recovery, and overall nutrition, especially when combined.
Choosing the Right Protein for You
The best protein powder depends on your goals, dietary needs, and preferences. If you train for a specific sport or event, it's also worth reading our sport-specific guides, such as whey protein for runners or best supplements for CrossFit athletes, to understand how protein fits into a broader nutrition plan.
Choose this if you want a budget-friendly everyday protein with good taste and texture.
Choose this if you want high protein, fast digestion and lower levels of lactose, carbs and fat.
Choose this if you prefer a light, fruit-flavoured protein drink rather than a creamy shake.
Choose plant-based protein if you follow a vegan diet or want to avoid dairy.
There isn't one protein powder that's best for everyone. Choose the format that makes it easiest for you to consistently hit your daily protein target.
No matter which type you choose, consistency is key. Pair your protein with a balanced diet and regular training, and you'll be well on your way to hitting your fitness goals. Many athletes also stack protein with creatine for additional strength and recovery benefits. See our creatine guide for more detail.
