About RXBAR
RXBAR is an egg-white protein bar. RXBAR describes their bars as using “real ingredients” you might find in your kitchen or pantry. They claim to source their ingredients responsibly, with most ingredients coming from the United States.
RXBAR flavors:
Peanut butter, Chocolate Sea Salt, Blueberry, Banana Chocolate Walnut, Chocolate Chip, Peanut Butter Chocolate, Coconut Chocolate, and Vanilla Almond.
Taste & Texture
For this review, I sampled the peanut butter flavor (though I’ve previously tried several other flavors). The main textural properties are from dates and peanut butter, the two main ingredients. I would describe the texture of these bars as chewy and gummy. The bars are oily to the touch due to the peanut butter in them. There are chopped peanuts throughout the bar that add a nice crunch. The egg whites are not evident in this bar and blend in well. The flavor of this bar was pleasant and not overly sweet.

ARE RXBARs HEALTHY? Bottomline
We gave RXBAR a score of 88/100, meaning they are an excellent option for regular use. These bars contain a good balance of carbs, protein, and fat. They are also made with good-quality ingredients and are less processed than other protein bars on the market.
On the negative side, RXBAR contains a high amount of total sugar. However, this sugar comes from dates, which are considered low glycemic index (meaning dates will digest slower than other forms of sugar). Although the total amount of sugar appears high, RXBARs contain the same sugar as 3-4 dates, which is an appropriate serving size for a snack.

Frequently Asked Questions
ARE RXBARs a healthy pre-workout snack?
The best pre-workout meal or snack will depend on the individual’s digestive tolerance, nutritional needs, and daily nutrient distribution. Generally speaking, the carbohydrate-to-protein ratio in RXBARs is suitable for pre-workout. The protein, fat, and fibre content of RXBAR may increase the risk of adverse gastrointestinal symptoms if consumed too close to a workout. However, most individuals will tolerate an RXBAR ~2 hours pre-workout.
Are RXBARs a healthy post-workout snack?
RXBARs are a source of carbohydrates and protein and may be suitable as a post-workout snack for those struggling to meet their needs from whole food. The amount of carbs and protein is sufficient for most recreational athletes post-workout as long as they get enough protein elsewhere throughout the day. Elite athletes or those with higher nutritional needs may require more carbohydrate and/or protein post-workout than RXBARs provide.
Do RXBARs help you gain weight?
No single food will cause weight gain alone. RXBARs can contribute to weight gain if the overall calorie intake is higher than the individual’s needs. It is easier to consume excess calories from energy-dense foods such as protein bars, as they are generally denser and less filling than whole foods.
Do RXBARs help you lose weight?
No single food will cause you to lose weight, however, RXBAR is a balanced option for those struggling with eating properly on the go. RXBAR can certainly be consumed as part of a healthy and balanced diet, however, we always suggest consuming most of your calories from whole foods first before relying on packaged items.
Are RXBARs keto?
RXBAR contains carbohydrates and is not keto-friendly.
Are RXBARs vegan?
RXBAR contains egg whites as a protein source and is not vegan.
Are RXBARs processed?
As a packaged food product, RXBARs have gone through processing in their development. However, the ingredients used in RXBAR are less processed compared to some other bars on the market.
Are RXBARs low FODMAP?

Is it OK to eat RXBARs every day?
An RXBAR can certainly be consumed daily as part of a healthy, balanced diet, however, we always suggest trying to get your daily meals and snacks from whole foods first.
How many RXBARs can you eat in a day?
For the purpose of getting enough variety in your diet and adequate nutrients, we suggest limiting your intake of RXBAR to no more than one per day.
Are RXBARs a healthy breakfast?

Are RXBARs gluten-free?

Snack bars can be a convenient snack option on the go. But with so many options out there, it can be overwhelming to find the best one for you. Check out these protein bar reviews to learn how your favourite bar measures up.
Are RX bars healthy for Type 2 Diabetes. Do the dates raise the blood sugar ?
Thanks for your question! Blood sugar response will vary depending on the person. Generally speaking, RX bars contain carbohydrates which will raise blood sugar. However, dates are considered a low glycemic index food and will result in a smaller rise and fall in blood sugar. In addition, RX bars contain protein and fats, which will lower the blood sugar response.
Wondering what amount of potassium and phosphorus per bar…are they safe for dialysis patients?
Thank you for your question! There are 410-480mg potassium per bar. The phosphorus content isn’t listed, but based on the ingredients, this flavour (peanut butter) has an estimated 76mg phosphorus.
I read an article from 2018, stating the egg whites are actually powdered egg whites. Is this true?
PS: I still enjoy this product.
Thank you for your comment! I haven’t been able to find what type of egg whites are used but I assume they would be using some form of dried egg white powder as the product is shelf stable.
I’ve been eating Rx bars for over 10 years now and have always loved their approach with “no BS” ingredients and tasty bars. They fit well into our healthy eating and active lifestyle. Recently, my wife bit into a bar that was months away from its expiration date that cracked her front teeth. We took pictures of the bar, the wrapper, expiration dates, product code, my wife’s now chipped teeth, and copy of a $2,000+ emergency dental bill. We contacted Rx bar on their site to which they responded promptly and gave us information to submit a claim. All they seemed to care about was finding out who in their facility was responsible for making this defective product. We followed all of their instructions, gave a detailed description to only be told 45 days later that because we threw out the defective product (the bar), they would be not help us at all. It was a very callus and uncaring response that showed zero empathy for our situation. All they did was send me two coupons for Rx bars that expired 30 days later…This has been extremely disappointing from a long time customer that will be telling every single one of my friends, gym members, and online communities what type of company Rx bar and Kellogg truly is.
The Blueberry bar says “3 Eggs, 6 Almonds 4 Cashews, 2 Dates, No B.S.”
Combining these ingredients does not result in a blueberry flavor so there is definitely some B.S. in the bar.
The list of ingredients on the front of the package is not the complete list. The full ingredient list is on the back of the package above the nutrition facts table. In the case of the blueberry flavour, it contains the ingredients you listed as well as blueberries and natural flavour.
