Protein bars
Protein bars for the days you don't have time to sit down and eat. Discover our own-brand protein bars: chocolate-coated ones, a vegan bar with plant protein, one with probiotics, one with creatine and an oat flapjack for breakfast.
When should you eat one? After training, between meals when dinner is still hours away, or as an afternoon snack on a busy day. Choose the texture: a dense flapjack for breakfast, crunchy coating for a mid-afternoon treat.
If you'd rather set the grams of each serving yourself, check protein powder and shakes; if what you need is carbs during exercise, energy bars. Own brand, with full composition on every product page.

Protein that fits in your jacket pocket
Protein bars to take with you
Protein bars solve a serving when you can't cook one. The difference between them isn't the flavor: it's how much protein they carry relative to their calories, and what else they add, from plant protein to creatine.

Choose by your goal
Your total daily protein matters more than the exact moment you eat it.
To build muscle mass
Protein contributes to a growth in muscle mass, and that claim can only be used if the food is at least a source of protein. Look for 'high protein' on the label and fit it into a 20-40g serving.
If you're cutting calories
Check the kilocalories per unit first: a bar with plenty of protein but very calorie-dense won't fit. Then, grams of sugar per 100g. Here calories set the limit, not protein.
After training
The bar covers the serving you need when a meal is two hours from your session. Between meals it competes with whatever you'd have snacked on instead: that's where it adds the most.
By your sport
In strength training, your daily protein total is what counts. In endurance sports, what you need during the effort is carbs: that's what energy bars give you.
The types you'll find here
Same job in all five, different base, texture and extra.
Flavored, with a coating
The flavored bar is the standard option: one for an afternoon snack or after training. There are chocolate, peanut, cookie and coffee flavors, for anyone who doesn't want to give up something sweet.
Vegan, with plant protein
The vegan bar swaps whey and casein, which come from milk, for plant protein. It's the first filter if you follow a vegan diet or lactose doesn't agree with you.
With probiotics
Probiotic bars carry added live cultures on top of the protein. The amount is on the product page, and the rest of the format is in probiotic bars.
With creatine
The creatine bar provides 3g of creatine monohydrate, the daily intake the EU ties its authorized claim to: on the day you eat it, that covers your intake. On days without the bar, stick with creatine powder.
Oat flapjack
The protein flapjack has an oat base and a dense, chewy texture, so it fits well at breakfast or mid-morning. If you want the oats without added protein, there are oat bars.
What to check before buying
Four facts that separate a protein bar from a sweet with added protein.
The claim, not your own math
'High protein' can only appear if protein supplies at least 20% of the energy value; 'source of protein', from 12%. Regulation (EC) No 1924/2006 sets it: reading the claim saves you the calculation.
Sugar, per 100g
'Sugar-free' requires no more than 0.5g of sugar per 100g, and 'low sugar' allows up to 5g: ten times more. It's the figure that changes most between two bars with the same protein.
Where the protein comes from
Whey and casein come from milk; pea, soy or rice protein doesn't. It's the first filter if you're vegan or don't tolerate lactose, and it's in the ingredients on the product page.
Allergens and the oat base
Several bars contain nuts or peanuts, and the oat-based ones aren't suitable for celiacs unless the page states certified oats. Check the ingredients, especially if you're buying for someone else.
Tip: a bar only works if you're carrying it: one in your gym bag and another in your office drawer keep the vending machine off your afternoon. For the rest of the post-session meal, see what to eat after the gym.
Frequently asked questions
When should I eat a protein bar?
After training and between meals. If you're torn between before and after, it matters less than it seems: according to the International Society of Sports Nutrition, your total daily protein counts for more than the exact minute. After is handy if your next meal is a long way off; before, pick one low in fat and fiber and give it an hour. Between meals, it replaces snacking.
Which protein bars are good?
There's no good one in the abstract: there's a good one for what you want it for. For muscle mass, the one that claims 'high protein'. To carry as a stand-in for snacking, the one with the fewest calories per unit. For a vegan diet, the plant-protein one. The label answers all three.
Which protein bars are good for gaining weight?
The ones with the most calories per unit, not necessarily the most protein: a 60-gram protein flapjack carries quite a few more calories than a flavored protein bar. Eat them on top of your meals, not instead of them, and compare each product page per whole bar.
Are protein bars healthy?
It depends on the composition, not the category. It works well when protein genuinely carries weight against the bar's calories and sugar stays low; it works badly when it's a cake with a bit of added protein. The ingredient list runs in order of weight: you can see it there in ten seconds.
Are there sugar-free protein bars?
There are none here that are 'sugar-free' in the legal sense (0.5g per 100g or less), but several are low in sugar (5g per 100g or less). 'No added sugars' only applies if no sugar or sweetening ingredient has been added, sugary chocolate included; the fruit's own sugar, as in dates, is still there, and the label must say 'contains naturally occurring sugars'.
Are there vegan or lactose-free protein bars?
Yes, there's a vegan bar with plant protein in the range. If you follow a vegan diet, also check two ingredients that sneak into sweet bars: honey and milk chocolate. If lactose is your only issue, any plant-protein bar works, and the product page states where each one's protein comes from.
What's the difference between a protein bar and an energy bar?
The macronutrient split and when you use it. The protein bar concentrates protein against its calories and covers part of your daily intake. The energy bar concentrates fast-absorbing carbs and is taken during a long effort. We compare them in energy bars vs protein bars.
How many protein bars can I eat a day?
One or two, as a practical rule. Useful servings sit at 20-40g of protein every 3-4 hours, and a bar only covers part of that. In a meta-analysis of 49 studies, going past 1.62g per kilo a day didn't add more lean mass.
What happens if I eat a protein bar every day?
Nothing problematic if it fits your calories and your daily protein: EFSA's reference for an adult is 0.83g per kilo of body weight, and people who train work with 1.4-2.0g per kilo. Do check the label: bars with polyols (maltitol, sorbitol) warn that excessive consumption may have laxative effects, so don't eat them back to back.
Do protein bars make you gain weight?
Not on their own. Body weight depends on the energy balance of your whole diet, not one food in isolation: a bar can fit into a deficit or break it, depending on what it replaces. The EU doesn't authorize any claim linking protein to body weight.
Is it worth making protein bars at home?
Homemade gives you full control over ingredients, but with a date-and-nut base they usually fall under the 12% energy-value threshold, so they aren't 'protein' bars in the legal sense. The blog has a homemade chocolate and nut bar recipe; to make them protein bars, add protein powder until you pass 12%.
