Shop Protein Bars at Myprotein
Protein bars are one of the most practical ways to hit your protein targets without preparing a full meal. Whether you're training hard or just trying to eat a bit smarter, having a bar that delivers real protein content in a format you actually want to eat makes a genuine difference. The range here covers everything from chewy layered bars and crispy wafers to flapjacks and snack-sized bites — so there's something to suit every preference and routine.
With protein content ranging from around 5g to 20g per bar, and formats built around flavour as much as function, these aren't the dense, chalky protein bars of a decade ago. Each product is developed with nutrition at the core, giving you a convenient source of protein that fits alongside a balanced diet and an active lifestyle.
Who Protein Bars Are For
Protein bars work for a wide range of people — not just those who train every day. If you're someone who finds it difficult to hit a decent protein intake through meals alone, or you're regularly on the go and need something convenient that doesn't compromise on nutrition, a protein bar does the job cleanly. Gym-goers, runners, cyclists, and anyone working towards a body composition goal will find them a natural fit.
That said, you don't need a gym membership to get value from them. Office workers looking for a smarter mid-morning snack, people managing busy schedules, or anyone trying to move away from lower-quality convenience foods will find plenty of options here. The variety of formats and flavour profiles means there's a bar for every eating preference, from those who want something indulgent-tasting to those who prioritise a cleaner ingredient list.
When to Use Protein Bars
The most common use case is post-workout, when getting protein in quickly and conveniently is the priority. Protein contributes to the growth and maintenance of muscle mass1, making bars with a higher protein content — like the Oat Protein Flapjack with 20g per bar — a practical choice after training when you're not in a position to prepare food straight away.
Beyond training, protein bars slot in well as a mid-morning or afternoon snack, as a desk lunch supplement, or as a pre-workout option when you want something light but substantial. They're particularly useful when travelling, commuting, or during long days where meal timing becomes unpredictable. Keep one in your bag and you've always got a reliable, protein-rich option within reach.
Protein Bars Benefits
Convenient Protein Source
The biggest draw of a protein bar is simplicity — no prep, no shaker, no fuss. With protein contributing to the growth and maintenance of muscle mass1, having a portable bar that delivers anywhere from 5g to 20g of protein makes it far easier to stay consistent with your intake across the day, regardless of your schedule.
A Wide Range of Formats
This isn't a one-size-fits-all category. Crispy wafers, layered bars, flapjacks, oatbakes, snack rolls, and variety boxes all sit within this range, covering textures and flavour profiles that rival standard confectionery. Whether you prefer something light and crunchy or dense and chewy, there's a format that actually appeals to eat.
Designed Around Real Nutrition
Every bar in this range is developed by Myprotein's expert nutritionists with a clear nutritional purpose. That means protein content front and centre, alongside considered macros — some options come with significantly fewer carbs and less fat compared to standard supermarket snack bars, without sacrificing the flavour that makes you want to eat them in the first place.
Variety to Keep Things Interesting
Sticking to the same bar every day gets old fast. With over 20 products across the range — from the Crispy Protein Wafer and Lean Layered Protein Bar to variety boxes — there's enough choice to rotate regularly and keep your snack routine from going stale. Different flavours, sizes, and protein levels mean you can match the bar to the moment.

FAQs
What are protein bars?
Protein bars are ready-to-eat snack bars formulated to deliver a meaningful amount of protein per serving — typically between 5g and 20g — in a convenient, portable format. They come in a wide range of textures and flavours, from crispy wafers and layered bars to flapjacks and oatbakes, and are designed to make hitting daily protein targets easier without needing to prepare a meal.
How many protein bars should I eat per day?
Most people find one to two protein bars per day fits naturally into a balanced diet. They work well as a snack between meals or alongside a lighter meal, rather than as a full replacement. The right amount depends on your overall diet and daily protein targets — check the nutritional information on each product to see how it fits into your intake for the day.
What are the best protein bars in Ireland?
The best protein bars depend on what you're after — protein content, format, or flavour. For high protein per bar, the Oat Protein Flapjack delivers 20g of protein per bar and is one of the most popular options. If you prefer something lighter and crunchier, the Crispy Protein Wafer offers 15g protein with 60% fewer carbs than supermarket alternatives. Both are available for delivery across Ireland.
Are protein bars good for muscle growth?
Protein bars can be a practical way to contribute to your daily protein intake. Protein contributes to the growth and maintenance of muscle mass1, so including protein bars as part of a diet that meets your overall protein needs makes sense for those focused on muscle development. The Oat Protein Flapjack, with 20g protein per bar, is a strong option for those with higher protein requirements.
Can I eat protein bars as a snack?
Protein bars are built for exactly this purpose. They're portable, require no preparation, and come in formats that genuinely taste good — from the Filled Protein Wafer, a lighter option at 4.8g of protein per bar, through to higher-protein options like the Layered Bar. Keep one in your bag, desk drawer, or gym kit for a reliable snack whenever you need it.
What's the difference between protein bars and protein flapjacks?
Protein flapjacks use oats as their base, giving them a chewier texture and a more substantial carbohydrate content alongside their protein content — the Oat Protein Flapjack delivers 20g of protein per bar. Standard protein bars vary more in format, from wafers and layered bars to crispy squares, and typically have different macro profiles. Both are valid options; the choice comes down to texture preference and your nutritional goals.
Are there different types of protein bars available?
The range covers a broad selection of formats: layered bars, crispy wafers, filled wafers, flapjacks, oatbakes, snack rolls, crispy squares, and variety boxes. There are also vegan options, high-carb bars designed around training, and single-serve samples if you want to try before committing to a full box. With over 20 products in the range, there's plenty of variety to suit different tastes and nutrition goals.
Who develops the protein bars?
All protein bars in this range are developed by Myprotein's expert nutritionists. Each product is built around a clear nutritional brief — prioritising protein content, flavour, and texture — while being manufactured to high quality standards. The range spans everything from indulgent-tasting layered bars to lighter wafer formats, all with the same attention to what's actually in them.
Are protein snack bars suitable for a high-protein diet?
Protein bars are a practical fit for anyone following a high-protein diet. With options ranging from around 5g to 20g of protein per bar, they give you a convenient way to add protein to your intake between meals. Protein contributes to the maintenance of muscle mass1, making regular protein distribution across the day — including through snacks — a sensible approach for those with active lifestyles.
Can I buy protein bars in bulk or as a variety pack?
Yes — several options in the range are available as variety boxes or multipacks, including the Layered Bar Variety Box and the Crispy Wafer Variety Box. These let you sample multiple flavours within a single purchase, which is useful if you're new to the range or want to avoid committing to a single flavour. Individual sample sizes are also available for some products.
