How Are These Different From Other Protein Bars?

Protein bars come in all shapes, sizes, and varieties these days. You don’t have to look hard to find high carb ones, low carb ones, high protein, high fat, gluten free, or low carb. However, most bars have that cardboard taste, cost too much, and leave more to be desired. The last few years, Quest Nutrition has been at the top with their Quest Bars, providing a filling protein bar with great taste to help build muscle. Now, ISS Research has noted what Quest has accomplished and brought forth the even better Oh Yeah! One Bar. This bar isn’t just a candy bar with protein added to it. They’ve taken the great macronutrient profile of Quest Bars and combined it with the amazing taste of their original Oh Yeah! Bar. And the name One Bar refers to the one gram of sugar!

ISS Research Oh Yeah! One Bar Key Ingredients Rundown

Whey Protein Isolate - This form has the most available protein you can get, generally over 90% without any carbs, lactose, or fat. It is more purified than whey concentrate, and is more easily digestible because it is lactose free. It also has a high BCAA content.

Milk Protein Isolate - This contains whey and casein proteins, which places it between the digestion rate of the two. Whey digests very quickly while casein has a much slower release. This consists mostly of casein, giving the bars a rich texture.

Isomalto-oligosaccharides - These are a combination of short-chain carbohydrates that are able to resist digestion, meaning you won’t get any particularly valuable nutrients from them. However, that doesn’t mean they are without benefits. They are low glycemic, resist cavities and are a source of prebiotics. Prebiotics promote the growth of healthy bacteria in the gut, resulting in smooth digestion. This ingredient is also what is used to sweeten the bars without raising the amount of sugar.

Maltitol - This is a type of sugar alcohol that’s used as a replacement for sugar. It has 75-90% of the sweetness of sucrose, but with half the caloric count. This also doesn’t promote cavities just like IMO, and it can be found in a wide range of foods like chewing gum, sugar-free chocolate, and hard candies. You might experience the “cooling feeling” that some get when consuming sugar alcohols.

Glycerine - The last major sweetener in these bars is glycerine. Another common sugar alcohol used in the food industry. This has 27 calories per teaspoon and has a lower glycemic index than sucrose. It won’t make your blood sugar skyrocket or give you the bottom out that comes with regular candy bars containing sugar and high fructose corn syrup.

One Bars.. incredibly Delicious, and healthy?!? What?!?

I ordered 2 different kinds and while Birthday Cake has initially been my favorite, starting to like the Almond more. One would think that would be plenty to keep people coming back for more, yet the kicker is, that unlike other snack bars, I do not get cravings for sweets. In a nutshell: LOVE, LOVE, LOVE One Bars!!!!


Best Price Nutrition

Hi Jennifer - These bars are fantastic aren't they! I personally used to be hooked on Quest Bars, but since these came out, I only eat Oh Yeah One Bars now! Birthday Cake is delicious. My other favorite is Salted Caramel...mmm! Anyway, thank you for taking the time to review your purchase. We really appreciate it!


White Chocolate Raspberry vs Quest

I was very impressed with the new One bar flavors: Birthday Cake, Almond Bliss, and to a lesser extend Chocolate Mint. However I am not as big of a fan of White Chocolate Raspberry. It it like a Raspberry flavored bar with White Chocolate coating, which is as described, however I found the Quest interpretation to be a lot better (more like a White Chocolate Raspberry cup cake). If you have tried Quest and were looking for more intense flavoring, then the One bar should hit the spot, however I didn't like it as much. Birthday Cake, and Almond Bliss are king, but this one is still pretty royal.



OMG the BIRTHDAY CAKE flavor is UNREAL. I'm sure everyone has heard the rave about this flavor! The best tasting birthday cake bar out there, for sure! The peanut butter one and the cookies and cream one and lemon pie are also in my top ranks, however, I really didn't like the raspberry white chocolate. I also really enjoyed the crunchy whey protein crispies inside the bar, making it the perfect on-the-go bar.


Chocolate Mint vs Quest

This morning I opened up a Chocolate Mint One bar. A simple description is that it is a spearmint flavoured bar with a chocolate coating. If that sounds good to you then you won't be disappointed (I wasn't). Previously I have had a Quest bar, and comparing to the mint flavour this one is quite different. Quest has nice mint chunks, but the rest of the bar isn't quite as chocolatey as hoped. Still enjoyable, but not passing as a chocolate bar. The One bar doesn't have any chunks of any kind, but the flavours are stronger and distinct. I like both, but I would suggest it would depend on my mood.


Almond Bliss has actual whole almonds!

I was really surprised to open up my first Almond Bliss bar and find real whole almonds coating the top! A real step up from the chunks a lot of bars have (that, while nice, lets face it, they often aren't real chunky). The centre of the bar is quite coconutty, making the whole thing great. In Australia we have a bar called 'Bounty' which this is really similar to. I've seen pictures of Almond Joy bars as well, which I guess this would be a lot like. I was really surprised. I expected something similar to Quest Coconut Cashew and was really impressed by this. I love it.


Birthday Cake has sprinkles!

The birthday cake bar had sprinkles! Very tasty and soft bar, and was amazing from the first bite. It may be a bit sweet for some, but you would expect a flavor called 'Birthday Cake' to be sweet! 210 calories per bar, 21g of protein, I have never had a protein bar quite like it.I was thoroughly impressed, and I'm sure you will be too. Once I ate my first I thought I made a mistake not ordering a second box! I would recommend this to anyone on a diet with a sweet tooth.



Looking at the other reviews I expected the One bars to be the next big thing. Lemon was called the best flavour and I had high hopes since I love lemon stuff. They were OK. But they weren't anything particularly special. I still prefer Quest bars. These were a great change, but I think in a market not oversaturated with Quest these wouldn't do so well. I think people rate them so highly because they are different. They are good, but I wouldn't crave them.


Not bad.

Not a bad bar. I had the opportunity to give the Chocolate Chip Cookie Dough flavor a go and i liked it a lot. Had a great texture not your usual health bar ***** consistency thing going on. The bar has a good amount of protein so that helped me meet my protein needs while also having a little snack. It is not loaded with a bunch of sugars and garbage which is great. The price is typical high quality protein bar cost.


Amazing protein bar

Oh yeah one bar is so good. I am used to the soybean type crisps in protein bars, but these do not contain soy and has a protein blend. It contains little to no sugar and contains 22 grams of protein. The best part of these bars is that they do not have that aftertaste some protein bars have due to artificial sweeteners. Def recommend these bars and is a must buy. My favorite is the peanut butter flavor.
