RXBAR - Dietitian Review




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 is available in seven flavours: 

Peanut butter, Chocolate Sea Salt, Blueberry, Banana Chocolate Walnut, Chocolate Chip, Peanut Butter Chocolate, Coconut Chocolate.

For the purpose of this review, we sampled the peanut butter flavour. The main textural properties are from dates and peanut butter, two main ingredients. We would describe the texture of these bars as chewy and gummy. The bars are oily to 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 flavour of this bar was pleasant and not overly sweet.

The ingredients in RXBAR are simple, and each flavour only has a handful of ingredients. The peanut butter flavour contains egg whites, peanuts, dates, natural flavours, and sea salt. We consider these bars to be high quality because the ingredients haven’t been ultra-processed like some other protein bars on the market.

Are RXBARs good for you?


RXBAR is an excellent choice for a healthy snack on the go. It has a good balance of fat, protein, and carbohydrate to keep you sustained, and good quality ingredients. 



ARE RXBARs a good 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: 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 good 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. 





RXBAR is not low FODMAP as dates are a source of FODMAPS.

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?


RXBAR provides a balance of healthy fats, carbs, and protein. As such, it can be a suitable option for a breakfast or snack on the go. RXBARs contain ~200 calories per bar and may not be adequate for those accustomed to having a larger breakfast. 



Are RXBARs gluten-free?


RXBARs do not contain any gluten in their ingredients, however, wheat is included in the ‘may contain’ statement. RXBARs are made in a facility that also processes gluten so they may not be safe for those with allergies. 



Are RXBARs dairy-free?


RXBARs do not contain any dairy in their ingredients, however, dairy is included in the ‘may contain’ statement. RXBARs are made in a facility that also processes dairy so they may not be safe for those with allergies.
