Protein blends combine multiple protein sources into a single formula, giving you a broader amino acid profile than single-source options alone. Whether that's whey concentrate paired with casein, or a plant-based combination of pea and rice, each source digests at a slightly different rate — meaning your muscles have access to amino acids over a longer window after training. Protein contributes to the growth and maintenance of muscle mass1, making a well-formulated blend a smart choice for anyone serious about their training.
The range here covers everything from high-calorie mass gainers and meal replacement blends to lighter everyday shake options, so there's a protein blend to fit almost any training goal or dietary preference. Formats include powders, pancake mixes, and mug cake mixes — making it straightforward to hit your daily protein target without it feeling like a chore.
Who Protein Blends Are For
Protein blends are a solid fit for gym-goers and athletes who want more from their protein powder than a single-source option can offer. If you're in a building phase, a blend like a mass gainer with carbohydrates and protein is designed for high-volume training demands. If you're watching calories more closely, a blend formulated with a lower calorie count still delivers a meaningful protein hit — typically 20g or more per serving.
They're equally well suited to people who simply want a convenient, versatile protein source for everyday use — not just around workouts. Protein blends that incorporate meal replacement formats work just as well at breakfast or as a between-meals option as they do post-training, making them a practical pick for busy lifestyles.
When to Use Protein Blends
The multi-source nature of a protein blend makes timing more flexible than with a fast-digesting single-source powder. Post-workout is the most common use case — pairing protein with carbohydrates after training is a well-established approach, and blends that combine both macronutrients are built with exactly that in mind. Protein contributes to the maintenance of muscle mass1, so getting enough across the day matters as much as when you take it.
Beyond post-workout, protein blends work well first thing in the morning, between meals, or as a higher-protein alternative to a standard snack. Mass gainer blends with a higher calorie and carbohydrate content are particularly well suited to use around training sessions or as an addition to meals, for those who struggle to hit their daily calorie targets through food alone.
Protein Blends Benefits
Multiple Protein Sources in One Formula
A protein blend draws from more than one protein source — often a combination of fast and slower-digesting proteins. This gives you a more complete amino acid profile in a single serving, without needing to mix and match separate products.
Formats for Every Routine
The range extends well beyond shakes. Protein pancake mixes, mug cake mixes, and meal replacement blends mean you can hit your protein target across breakfast, snacks, and main meals — not just in a post-gym shake. Protein contributes to the maintenance of normal bones2 too, so meeting your daily intake across a variety of meals makes sense.
Options Across the Calorie Spectrum
Whether you're tracking a lean intake or actively trying to eat more, there's a blend built for it. Mass gainer blends deliver serious calorie and carbohydrate counts per serving, while lighter options come in under 150 calories — so the range genuinely covers both ends of the goal spectrum.
Developed by Nutritionists
Every protein blend is formulated by Myprotein's expert nutritionists, with dosing, ingredient selection, and flavour all considered from the ground up. That means you're not just getting protein — you're getting a product built around how people actually train and eat.

FAQs
What is a protein blend?
A protein blend is a powder that combines two or more protein sources — for example, whey concentrate and casein, or pea and rice protein — into a single formula. Because each source has a slightly different digestion rate, a blend delivers amino acids across a broader timeframe than a single-source powder. Protein contributes to the growth and maintenance of muscle mass1, and blends are one of the most flexible ways to hit your daily target.
What's the difference between a protein blend and a single-source protein?
A single-source protein — like a pure whey isolate — is derived from one ingredient and digests at a predictable rate. A protein blend combines multiple sources, each with a different absorption profile, so the amino acid supply is more sustained. Blends also tend to have a broader nutritional makeup, particularly when they include carbohydrates, making them suitable for a wider range of goals and timings.
What is the best protein blend for building mass?
For serious mass-building goals, Origin Mass Gainer delivers 1,000 calories and 50g of protein per shake, contributing to muscle growth and maintenance1. Impact Whey Mass Gainer is another strong option, providing 30g of protein and 50g of carbs per serving — a well-rounded formula for high-volume training phases. Both are designed to make hitting a significant calorie surplus more manageable.
How much protein is in a typical blended protein powder?
Protein content varies by product and format. Standard protein blend shakes typically deliver 20–30g of protein per serving, while mass gainer blends can reach 50g per shake. Lower-calorie options like Essential Whey Protein Shake provide at least 20g per serving at under 150 calories. The right amount depends on your overall daily protein intake and training demands.
Can protein blends be used as meal replacements?
Several products in the range are formulated specifically as meal replacement blends, designed to deliver protein alongside other macronutrients in a balanced format. These work well at breakfast or as a structured between-meals option. Standard protein blends are generally intended to complement meals rather than replace them, so it's worth checking the product format before using it that way.
Are protein blends suitable for vegans?
Yes — Impact Vegan Protein is among the options on this page, combining plant-based protein sources to deliver a complete amino acid profile without any animal-derived ingredients. Vegan protein blends typically combine pea and rice protein, which together provide all nine essential amino acids. Check the product page for full ingredient and allergen information.
When is the best time to take a blended protein powder?
Protein blends are versatile enough to use at several points in the day. Post-workout is a popular choice, particularly blends that also include carbohydrates. First thing in the morning, between meals, or as part of a higher-protein snack are all practical options too. Mass gainer blends with higher calorie counts are best timed around training sessions or added to meals when daily intake needs a significant lift.
Who develops the protein blends at Myprotein?
All protein blends are developed by Myprotein's expert nutritionists, who determine ingredient selection, protein source combinations, macro ratios, and dosing. The range is built around real training needs — whether that's a high-calorie shake for mass building, a lighter everyday option, or a food-format blend like pancake or mug cake mixes.
What formats do protein blends come in?
The range includes powder shakes, mass gainers, meal replacement blends, protein pancake mixes, mug cake mixes, and breakfast smoothies. This variety means you can work protein into your routine across multiple meals and snack occasions — not just as a post-workout shake. All powder formats are designed to mix easily with water or milk.
How do I choose the right protein blend for my goal?
Start with your daily calorie and protein targets. If you're in a calorie surplus phase, a mass gainer blend with 50g protein and significant carbohydrate content is the logical starting point. If your priority is protein intake without adding a lot of extra calories, a standard blend delivering 20–25g per serving at under 150 calories is more appropriate. For plant-based diets, a vegan protein blend combining pea and rice protein covers the essential amino acid bases.
