Whey protein comes in many forms, each created through a specific process that affects its nutritional profile, texture, and taste. Among the most popular options are the traditional creamy shake, often exemplified by Myprotein's Impact Whey, and the modern, light, and fruity alternative, Clear Whey. While both are effective for muscle growth and recovery, their differences can significantly impact your daily intake and overall experience.
What is Clear Whey Protein?
Clear whey is a highly refined protein derived from whey protein isolate. Unlike standard whey, it undergoes a special process that includes additional filtration and hydrolyzation. This breaks the protein down into smaller components, which results in a fine powder that dissolves completely in water, creating a translucent, juice-like beverage. It is then flavored with fruity options like tropical, lemonade, or berry flavors.
Because of this advanced processing, clear whey is low in calories, fat, and carbohydrates, with significantly less lactose than whey concentrate. This makes it an excellent option for individuals who are lactose sensitive or those on a strict calorie-deficit diet. The light, refreshing consistency is particularly appealing for post-workout hydration, especially in warm weather, as it avoids the heavy, creamy feel of a traditional shake.
Key characteristics of Clear Whey:
- Source: Hydrolyzed Whey Protein Isolate.
 - Process: Advanced filtration and hydrolyzation to break down proteins.
 - Texture: Light, clear, and juice-like when mixed with water.
 - Flavors: Fruity and acidic, such as peach tea, lemon, and berry.
 - Digestion: Faster absorption and easier on the stomach, particularly for those with mild lactose intolerance.
 - Ideal Use: Post-workout recovery, hot weather hydration, and cutting phases.
 
What is Impact Whey Protein?
Impact Whey, often referencing a brand's standard whey concentrate, is a less processed form of whey. The manufacturing process involves filtering the liquid whey leftover from cheese production and then drying it to create a powder. This process leaves a higher concentration of beneficial nutrients like calcium and potassium, but also retains some fat, carbs, and lactose.
This composition gives Impact Whey its classic, creamy, and milky texture, making it ideal for traditional protein shakes mixed with milk or blended into smoothies. Its flavor profile typically includes rich dessert-like options such as chocolate, vanilla, and salted caramel. As a versatile, all-purpose protein, it offers great value and is a robust choice for a variety of fitness goals.
Key characteristics of Impact Whey:
- Source: Whey Protein Concentrate.
 - Process: Standard filtration of liquid whey.
 - Texture: Creamy and milky when mixed with liquid.
 - Flavors: Dessert-like, such as chocolate, vanilla, and cookies & cream.
 - Digestion: Generally fast-digesting, though the higher lactose and fat content may cause bloating for some individuals.
 - Ideal Use: Post-workout shakes, meal replacement smoothies, and general protein supplementation.
 
The Scientific Difference in Processing
The core distinction between these two protein types lies in the level of processing. Whey concentrate is the least refined form, containing around 70-80% protein by weight, along with some fats and lactose. This is a cold-temperature separation process using porous membranes. To create a higher-purity product like whey isolate (the base for clear whey), the concentrate undergoes further microfiltration to strip away more of the fat and lactose, achieving 90%+ protein content. Clear whey takes this a step further with hydrolyzation, pre-digesting the protein to increase its solubility and transparency.
This additional processing for clear whey explains its higher cost and unique characteristics. The pre-digested proteins are often advertised as being absorbed more quickly, though research to fully substantiate this claim specifically for clear whey is limited. However, the real-world benefits of better digestibility for sensitive stomachs and a lighter texture are well-documented.
Clear Whey vs. Impact Whey Comparison
| Feature | Clear Whey | Impact Whey | 
|---|---|---|
| Protein Source | Whey Protein Isolate (often hydrolyzed) | Whey Protein Concentrate | 
| Processing | Highly refined, extra filtration and hydrolysis | Standard filtration | 
| Texture | Light, thin, and juice-like | Thick, creamy, and milky | 
| Flavors | Fruity (e.g., tropical, berry, lemonade) | Dessert-like (e.g., chocolate, vanilla) | 
| Digestion | Easier on the stomach due to low lactose content | May cause bloating for those sensitive to lactose | 
| Lactose Content | Very low to virtually zero | Small amounts present | 
| Calorie Count | Lower per serving (~80-90 kcal) | Slightly higher per serving (~100-115 kcal) | 
| Cost | Generally more expensive due to extra processing | More budget-friendly | 
| Ideal For | Hydration, post-workout refreshment, cutting phases | All-purpose protein, meal replacement, bulking | 
Which One Should You Choose?
The decision between clear whey and Impact whey depends largely on your personal goals, preferences, and dietary needs. Consider the following factors:
- Taste and Texture: If you find creamy, milky shakes unappealing, especially after a tough workout or in hot weather, clear whey’s refreshing, juice-like consistency is a game-changer. If you enjoy a thick, classic milkshake-style shake, Impact whey is the clear winner.
 - Digestion and Lactose Sensitivity: For anyone with a sensitive stomach or mild lactose intolerance, clear whey's low-lactose content offers a more comfortable and bloat-free experience. Impact whey contains small amounts of lactose, which can be an issue for some.
 - Nutritional Goals: If you are in a calorie deficit or cutting phase and need to minimize fat and carbohydrate intake, clear whey's leaner profile makes it the more precise choice. For those looking for an affordable, general-purpose protein to supplement their diet, Impact whey is a high-value option.
 - Hydration: Clear whey, mixed with water, can contribute significantly to your hydration levels alongside your protein intake, making it perfect for intense, sweaty workouts.
 
Conclusion: Prioritizing Your Personal Preference
Ultimately, there is no single 'better' option between clear whey and Impact whey; it's about finding the right fit for you. Both deliver high-quality protein to support muscle repair and growth. The real difference lies in the sensory experience and minor nutritional variances due to different levels of processing. Whether you crave a light, fruity thirst-quencher or a rich, creamy shake, both options serve the fundamental purpose of meeting your daily protein needs. The best protein is the one you will consistently enjoy and stick with, so experimenting with both can help you decide which one earns a permanent spot in your gym bag.
