Real reviews from real customers
This is the ONLY protein mix that doesn't make me feel bloated and gassy. Mixes well! I have used both milk and water with it. Both are fine, milk makes it just a little better. Isn't overly sweet which I very much like. I will try the vanilla this time but I'm sure it will be great.
Strawberry flavour are easy the best. My go to protein treat. Don't make you feel crap like some protein bars do
Will be buying again. Nice and cheap and tasty. They're on the drier side but not enough to put me off. I usually pick up 3 or 4 boxes and stock up for a few weeks
The best protein flapjack for breakfast time
These are literally the best vegan bar I’ve ever tasted. I can’t even Tell you how many I’ve eaten since they launched. You would not think you were eating a protein bar. These are better than the real thing!
I drink this at work in the morning. It does have kind of an oatmeal taste, so it's perfect in the morning. I wish there were a few more flavor a but the three they have are pretty good. Overall, worth the money
Not usure if I like banoffee caramel but the rest of the flavours are absolutely delicius will be buying again soon! They're ideal as a bit of a mid morning snack!!
Great for only £20 and not bad macros at all actually
the salted caramel protein bar is the nicest I’ve ever tried. I’m amazed that it’s vegan too, these satisfy a sweet craving and I can’t get enough
Really didn't expect these to be as good as they are, especially for a vegan protein bar. Most of them are rank. Chocolate orange is just like terry's love it
Love these. I really struggle finding snacks that suit my diet. These are great during the day whne I don't have time to prepare food
Got these as a Christmas present and never thought I’d jump ship from carb killer but these bars beat them in every way, tastes, macros and calories. Salty caramel is absolutely amazing
"Great taste and great macro !
Really tasty brownie, one of the best I’ve tried, easy to consume, doesn’t taste like the other dry protein brownies I’ve tasted and lovely dipped into a cup of tea. Low sugar & 17g protein per bar! "
Millinoaire Crunch is amazaing. Didn't expect something this good considering its vegan and gluten free AND low in sugar. Hazelnut is lush. They're a bit dangerous though i could easy get through abotu 10 boxes
Delicious, soft and there is no protein taste! My favourite flavour is Cookies & Cream and Strawberries :)
Great tasting protein, have it every morning to supplement my fibre intake!
15 seconds in the microwave is the sweet spot to choccy heaven!
They're a little bit dry but for the money they're incredible!!
Double choc chip cookie, not bad, nice chunks of chocolate, juicy, no powdery taste like some cookies
I’ve now become addicted to the salted caramel
Thanks Oatein these are AMAZING. If you ever want to send me some freebies I'm all game for them :PP
these are some of the best protein bars on the market I dunno how Oatein have done it. Wooooowww. Geif mor lol
favourite is the salted caramel. I'm a vegan and these are some of the best protein bars I've had in ages. Will be ordering again soon
These flap jacks are great to eat anytime. Great tasting and just the right texture. Whether it's brownies or cookies Oatein is always my 1st choice.
Great snack for my sweet tooth ....great company to deal with
Great products at a fantastic price! Much better alternative to all the mainstream brands out there, will continue buying!
Love these protein flapjacks, so tasty!
I'm an avid eater of protein bars and purchased a box of 20 of these in 3 different flavours. My husband and I are totally loving them (my personal favourite being the cookies and cream flavour). They're super tasty and great as a protein packed snack
The running Tan
Was really impressed with this, plenty of white chocolate chunks distributed throughout and it had a bit of an Oreo taste to it which I loved!! Would definitely recommend it as a treat but the macro's are a little high for it to fit in my every day eats :)
Got them for £1 so wouldn't complain whatever they are like. They're actually mint though!! Nice and soft texture they're spot on when I got out running
Nom nom nom nom nom nom Nom nom nom nom nom nom
One of the few bars that actually tastes like the flavour it it meant to. Picked up 2 boxes at FIBO this year and can't wait to replace the grenade flapjack with this!
Got 40 bars for £20, that’s 50p a bar!!! They taste great and I have 2 every morning for my breakfast. Cherry bakewell is my favourite
Nice cheap little snack. Can't go wrong when they're on offer for next to nothing. Favourite is cookies and cream
They taste seriously brownie-alike but really, really low in sugar. Won't have them every day because I like to keep my food clean even if it's not really bad - if that makes sense! Basically I don't want to get into the habit of eating brownies all the time.
Absolutely delicious, they've got the flavour and texture completely down. Very impressed. Can't really say anything negative except i hope for a larger version of this bar in the future maybe in the 300 calorie range. Salted caramel best but all flavours spot on 5*
Tastes so good that I would actually choose one over a chocolate bar! Only 'downside' is that it doesn't 'taste' healthy, so it feels like you're cheating... But you're not!
Only 10 of protein isn't great but considering theyre half the size of other protein bars it makes sense lol. I like the strawberry ones, they taste pretty 'authentic' if that makes sense
Great taste and nice soft texture would buy agaib
Favorite protein. I mix with unsweetened almond milk post workout and the added fiber keeps me full longer. Tastes great too.
These are with out a doubt the best tasting, healthiest protein flapjacks I’ve ever had. Cherry bakewell and cookies and cream are my favourites
Best protein I've used, good taste easy to blend no bloating and good service from seller!
These cheeky devils hit the spot they are the most nutritious tasting flapjacks I have ever eaten with a whopping 18g protein great for breakfast or before your workout or with your coffee in the afternoon. My favourite so far cookies and cream.
I got these in January from Aldi, and they are amazing! I'm yet to find a better tasting vegan protein bar. Salted caramel is my new favourite
Just had the Salted Caramel Millionaire Crunch and it is without a doubt the best protein bar on the market! I hadn’t found any nice protein bars being vegan so the fact this is nicer than normal ones and such a good price is amazing! Pass me a whole box!
Best texture / natural tasting flapjack I have ever tried tbh. Easy to smash one back for a snack.
Really chocolatey with no chemical aftertaste
Picked them up on special offer in a taster box with some other oatein products. salted caramel is my new faovurite. They're spot on
These taste amazing better than any protein bar I've tried so far. Warmed up in the microwave for a few seconds makes a great dessert with a little ice cream
Really nice snack I have one of these every day when that mid afternoon lull kicks in.
Got to try these in the vegankind box. Loved it, way better than most vegan protein bits. Especially when they're this low in sugar
Bought them on a bit of a whim but they're probably one of the better protein bars out there. Nice for a change from grenade and rbars
I love sncaking on something with a bit of natural oats in to keep me going. Just feels abit more wholesome and like real food than a protein bar does. The oatein flapjacks look a bit shit but they're actually delicious. Would recommend!
Not normally what I'd buy but got them in the taster box with all of oateins other products and was pleasantly suprised. Definitely what you want if you're looking for something that feels more like real food
I tried one of these today and it was absolutely amazing (salted caramel)! I can't recommend these enough!!! 5*
the new flapjacks are much better than the old ones. Softer, chewier and waay better macros.
Milk and cookies can only be described as absolutely lush. Hype are now my favourite protein bar
these are kind of like a millionaire shortbread (duh!). Obvioulsy they don't contain any sugar so they're not sweet in quite the same way as the real thing. They're incredible though. 2 seconds in the microwave and they're unbelieveably goood!
Nice and natural, cheap. Box make a bit battered so for the money they taste spot on
Fast delivery. Good product
Couldn’t find a single thing that brings it down. Gorgeous smooth chocolate coating, good tasting protein, lovely gooey caramel-like layer and little crunches on top. Try shopping through my link :) https://www.oatein.com/r/O5qAF4Ea/
Found these in Aldi and as a chocolate lover who has been vegan 2 years and goes to gym they ticked all my boxes, didn’t expect much and was blown away. Definitely one of the best vegan treats I’ve had in 2 years, and I’ve had almost all of them!
Millionaire Crunch is UBELEIVEABLE. Really didn't know what to expect but I'm addicted lol
Stupidly cheap reallly arent they!! Love them for how cheap they are
One of the best vegan protein bars i have tried, will be ordering more!
I bought these bars when they were on special offer. Didn't expect much from the low cost, but I have to say I was very pleasantly surprised. Very tasty little brownie. Very crumbly like it has been bought from the bakers. Taste was spot on too, very easy to consume, which could be a negative if you...
I am obsessed with the salted caramel millionaire crunch. The taste is unbelievable and feels like such a decadent treat when In fact they aren’t that high in calories for a treat. The fact they have 15g protein and are vegan all for 215 calories is a winner for me Also a bonus is palm oil free ...
Give these 2 seconds in the microwave and they're even better. Good macros, and a good taste i'll be buying again
The best protein I've had. The taste is good and the nutritional benefits are great. It's a very filling shake. Would highly recommend!
got these when on offfer for £20 for 40. Weeelll worth it. Good macros, healthy ingredients really cheap
Woke up later than planned today, didn’t have time to eat before training so mixed up my aminos and grabbed another on of Daves’ samples from the goody bag. ——————————————————- I’ve tried the @oatein bars before and really liked them, last time I used the 1...
Wow ridiculously good value.
