Meal replacement shakes are one of the most practical ways to hit your nutrition targets without spending time prepping every meal from scratch. Each product in this range is built around high protein content and a broad spectrum of vitamins and minerals, giving you a structured, convenient alternative to a sit-down meal — whether you're at your desk, on the go, or post-training.
The range spans shakes, blends, bars, and snacks, so there's a format to suit every routine. From creamy protein shakes to on-the-move bars, every option is formulated by Myprotein's expert nutritionists to deliver real nutritional value in a format that actually fits into a busy life.
Who Meal Replacement Shakes & Snacks Are For
These products are built for people who want to eat well without it taking over their day. If you're managing a calorie-conscious diet but still need to hit your protein and micronutrient targets, meal replacement shakes and snacks give you a structured, measured option that removes the guesswork from your nutrition.
They're equally useful for active individuals who train regularly and need fast, reliable nutrition around their schedule. Whether you're an early morning gym-goer, someone managing multiple meals across a long workday, or simply looking to add more structure to what you eat, this range is built to slot in wherever a full meal can't.
When to Use Meal Replacement Shakes & Snacks
The most common use case is as a direct swap for one or two meals during the day — typically breakfast or lunch, when time is tight and cooking isn't practical. Protein Meal Replacement Blend and Breakfast Smoothie, for example, are designed with this in mind: high in protein and dietary fibre, packed with vitamins and minerals, and quick to prepare.
Bars and snacks from the range work well between meals when you want something with nutritional substance rather than empty calories. Keep one in your bag for the commute, between meetings, or post-training when you need something fast. Timing is flexible — these are designed to work around your day, not the other way around.
Meal Replacement Shakes & Snacks Benefits
High in Protein
Protein is the headline ingredient across this range. Products like Impact Diet Whey deliver up to 36g of protein per serving, while Breakfast Smoothie provides 23g. Protein contributes to the growth and maintenance of muscle mass1, making it a non-negotiable part of any structured diet.
Packed with Vitamins and Minerals
These aren't just protein shakes — they're formulated to cover a broad nutritional profile. Many products in the range are high in vitamins and minerals that you'd typically source from a full meal, making them a genuinely complete option rather than just a protein hit.
Supports a Structured Diet
Used as part of an energy-restricted diet, substituting one daily meal with a meal replacement contributes to the maintenance of weight after weight loss2. Substituting two daily meals of an energy-restricted diet with meal replacements contributes to weight loss3. Having a consistent, measurable option makes it easier to stay on track day to day.
Multiple Formats for Every Routine

FAQs
What are meal replacement shakes?
Meal replacement shakes are nutritionally formulated drinks designed to substitute a full meal. They're built around high protein content and enriched with vitamins and minerals to deliver the kind of nutritional profile you'd expect from a balanced meal — in a fast, convenient format. Most are available as powders you mix with water or milk.
What are the best meal replacement shakes for a high-protein diet?
Impact Diet Whey is one of the strongest options in the range for protein content, delivering up to 36g per serving alongside choline, which contributes to normal lipid metabolism4. Protein Meal Replacement Blend is another solid pick — it's high in both protein and fibre, and packed with vitamins and minerals for a more complete nutritional profile.
Can meal replacement shakes be used for weight management?
Substituting one daily meal of an energy-restricted diet with a meal replacement contributes to the maintenance of weight after weight loss2. Substituting two daily meals of an energy-restricted diet with meal replacements contributes to weight loss3. The key is using them as part of a calorie-controlled diet rather than as an add-on to your usual meals.
Are meal replacement shakes available in Ireland?
Meal replacement shakes from Myprotein are available to order online and delivered to Ireland. The full range — including shakes, blends, bars, and snacks — is accessible through the website, with the same product selection available regardless of location within Ireland.
What's the difference between a meal replacement shake and a protein shake?
A protein shake is primarily designed to deliver a high dose of protein and is typically used alongside regular meals. A meal replacement shake is formulated to stand in for a full meal — it contains protein but also a broader range of vitamins, minerals, and fibre to more closely replicate the nutritional value of eating. They serve different purposes and are built to different nutritional specs.
Are there meal replacement bars as well as shakes?
Protein Meal Replacement Bar is available in this range for those who prefer a solid format over a shake. It delivers the same structured nutritional profile in a portable, no-prep format — useful when you're travelling, between meetings, or anywhere mixing a shake isn't practical.
Who developed the meal replacement products at Myprotein?
Every product in the Myprotein meal replacement range is developed by Myprotein's expert nutritionists. Each formula is built to precise nutritional standards — protein content, vitamin and mineral profiles, and macronutrient balance are all carefully considered to ensure every product earns its place in a structured diet.
How do I choose the right meal replacement shake for me?
Start with what you want from it. If maximum protein per serving is the priority, Impact Diet Whey is hard to beat at up to 36g per serving. If you want something that functions more like a complete breakfast, Breakfast Smoothie provides 23g of protein alongside high dietary fibre. For the most comprehensive nutritional coverage, Protein Meal Replacement Blend is formulated to be high in protein, fibre, vitamins, and minerals.
How many meal replacement shakes can I have per day?
Most people use one or two meal replacement shakes per day as substitutes for regular meals. Using two per day as part of an energy-restricted diet is the basis for the authorized weight loss claim3. Beyond that, it's worth ensuring your overall diet still includes a variety of whole foods to cover the full range of nutritional needs.
What formats are available in the meal replacement range?
The range includes powder-based shakes you mix yourself, pre-formulated blends, breakfast-style smoothies, bars, and specialist snacks — including keto-focused options.
