RxBar is a snack brand that offers protein bars available in flavors like Chocolate Sea Salt, Peanut Butter, Blueberry, and Vanilla Almond.
The brand’s product range also combines Rx Minis (smaller versions of the original bars), oat-based breakfast bars, and standalone nut butters. RxBar offers products in multiple pack sizes, including single-flavor boxes and mixed variety packs. The overall range spans snack, breakfast, and on-the-go formats, with a focus on protein delivery.
In this RxBar review, we will explore the brand offerings of RxBar, along with the brand's advantages and limitations. To provide a comprehensive view of RxBars, we’ll also compare it with other similar brands in the snack space.
RxBar claims to offer a wide variety of protein bars made with whole-food ingredients. The brand claims that each bar includes egg whites for protein, dates as a binder, and nuts like cashews or almonds for texture. Depending on the flavor, other ingredients may include cinnamon, natural flavors, pumpkin, and cloves.
RxBar highlights this minimal approach, signaling the absence of additives such as artificial sweeteners, preservatives, or fillers. The core product line consists of RxBar combines protein bars providing about 12 grams of protein per serving. These are available in 12-bar packs, as well as in multi-flavor options like the Classic 4-Flavor Variety Pack, Chocolate Lovers Pack, and Sampler Pack. The brand also releases seasonal flavors like Pumpkin Spice, which combines ingredients such as pumpkin, cinnamon, and cloves.
RxBar has also expanded into other formats, including its Nut Butter & Oat series. These bars feature oats, honey, egg whites, nuts, and crispy brown rice, offering around 10 grams of protein per bar. Flavors in this line include Blueberry Cashew Butter, Dark Chocolate Peanut Butter, and Honey Cinnamon Peanut Butter.
The brand also offers mini versions of these bars are also available in various mixed-flavor packs. These are designed for you if you are looking for smaller portions or convenient, on-the-go options. Examples include the Strawberry & Blueberry Minis and the Chocolate Sea Salt & Peanut Butter Chocolate Minis. According to the official website, RxBar maintains a consistent formulation strategy focused on ingredient transparency and minimal processing across all product lines.
The RxBar Pumpkin Spice Protein Bar (Box of 12) provides 12g of protein, primarily from egg whites, which serve as a lean, high-quality protein source without added fat or cholesterol. It also includes dates, which are used to hold the bar together while providing natural sweetness and fiber.
Cashews and almonds in the Pumpkin Spice Protein Bar provide healthy monounsaturated fats and plant-based protein, which may support heart health and muscle maintenance. Their crunchy texture enhances satiety by increasing chewing time and stimulating satiety hormones like GLP-1 and peptide YY, helping with appetite regulation. Pumpkin adds soluble fiber and micronutrients such as beta-carotene, supporting digestion and immune function.
Cinnamon and cloves in Pumpkin Spice Protein Bar contribute natural flavor and contain bioactive compounds like cinnamaldehyde and eugenol, which have antioxidant and anti-inflammatory properties. These ingredients create a seasonal flavor profile without relying on synthetic additives.
The makers state that the Pumpkin Spice Protein Bar is intended as a portable protein snack and may be used to supplement energy needs throughout the day or around workouts. These bars are also available in different flavors such as strawberry, coconut chocolate, vanilla almond, chocolate sea salt, peanut butter, peanut butter chocolate, and blueberry.
RxBar Nut Butter & Oat Protein Bar in Blueberry Cashew Butter flavor contains 10 grams of protein, primarily sourced from egg whites. It includes ingredients such as cashew butter, blueberries, whole grain oats, almonds, and cashews. The brand claims that the protein content, sourced from oats and nut butter, may help with satiety and muscle recovery.
As per the official website, the Nut Butter & Oat Protein Bar line also offers bars available in Dark Chocolate Peanut Butter and Honey Cinnamon Peanut Butter flavors.
The Chocolate Sea Salt & Peanut Butter Chocolate Minis are a protein snack by RxBar as a 24-count variety pack. Each box contains individually wrapped mini bars featuring two flavors, such as Chocolate Sea Salt and Peanut Butter Chocolate. These bars are compact and portable, with each mini containing 6 grams of protein.
According to the brand, the minis are intended to provide a convenient, on-the-go source of energy. RxBar claims that each mini bar may help with muscle maintenance, cellular repair, and enzyme production.
The bars in The Chocolate Sea Salt & Peanut Butter Chocolate Minis contain peanuts or peanut butter, depending on the flavor. These contribute to the fat content of the bar and supply monounsaturated fats, which could support cardiovascular health and sustained energy. The brand claims these minis help support satiety, energy, and nutritional balance during busy parts of your day.
The RxBar Sampler Variety Pack contains 10 protein bars with a mix of standard RxBar flavors and selections from the Nut Butter & Oat line. It is intended to help you if you want to try multiple varieties without purchasing full-size packs.
As per the official website, each protein bar provides approximately 190 calories, along with 7 grams of fat, around 1 gram of saturated fat, 0 grams of trans fat, about 5 milligrams of cholesterol, and 140 milligrams of sodium. Carbohydrates total 24 grams, including 6 grams of dietary fiber and around 14 grams of total sugars, with 0 grams of added sugar. Each bar contains 12 grams of protein. Bars from the Nut Butter & Oat line typically contain 10 grams of protein and may vary slightly in weight and nutritional profile.
Flavors commonly included in the sampler Variety Pack are Chocolate Sea Salt, Blueberry, Coconut Chocolate, Peanut Butter, Strawberry, Peanut Butter Chocolate, and Vanilla Almond. Nut Butter & Oat varieties may include Honey Cinnamon Peanut Butter, Blueberry Cashew Butter, and Dark Chocolate Peanut Butter. Ingredient combinations vary slightly by flavor. For example, some bars contain almonds or cashews, while others include oats and honey.
According to the official website, RxBar Minis Variety Pack contains 32 mini protein bars, which provide 100 calories, 6 grams of protein, 4.5 grams of total fat (1 gram saturated), 11 grams of carbohydrates, 2 grams of fiber, and 6-7 grams of sugar with no added sugars. Sodium content is 90 mg, and the bars contain no cholesterol or trans fats.
The protein source in each mini protein bar is primarily egg whites, and other key ingredients include dates for sweetness, nuts for fats and texture, and natural flavors such as fruit or spices, depending on the variety.
The Minis Variety Pack includes multiple flavors, such as Chocolate Sea Salt, Peanut Butter, Strawberry, and Blueberry. These are smaller versions of RxBar’s regular bars, intended for controlled portions or portability.
The RxBar Variety Pack contains 12 full-sized protein bars across six different flavors. These typically include Chocolate Sea Salt, Peanut Butter Chocolate, Blueberry, Mixed Berry, Vanilla Almond, and Coconut Chocolate. This pack is structured to offer multiple flavor types in a single box. All bars in the pack contain egg whites, dates, and nuts. These ingredients are used to provide protein, natural sweetness, and dietary fat. Each bar in this variety pack includes approximately 12 grams of protein.
RxBar lists its main ingredients on the front of each package, for example, “3 Egg Whites, 6 Almonds, 4 Cashews, 2 Dates” on the Chocolate Sea Salt bar. This format simplifies the ingredient breakdown, eliminating the need to examine a full panel on the back. According to the brand, their bars use pasteurized egg white powder as a protein source, dates for texture and sweetness, and heat-treated nuts like almonds, cashews, and peanuts. The bars do not include artificial flavors, preservatives, added sugars, or protein isolates.
As per the official website, RxBar uses unsweetened cacao in some bars for chocolate without dairy or soy, and the natural flavors come from plant-based oils and extracts. This labeling approach allows you to identify what you're consuming without interpreting complex ingredient lists. If you're limiting processed additives, tracking allergens, or avoiding unfamiliar substances, RxBar’s ingredient format may make comparison and selection more straightforward.
RxBar’s core brand advantage lies in its functional protein sourcing. Each bar contains 12 grams of protein derived primarily from egg whites, which are a complete protein source, meaning they include all nine essential amino acids your body cannot produce on its own. Egg whites are also highly bioavailable, allowing for efficient absorption and utilization by the body. Egg whites are gentle on the digestive system and require minimal processing, aligning with RxBar’s “clean label” philosophy of using simple, whole-food ingredients like dates and nuts without artificial additives or preservatives.
Compared to other brands, RxBar takes a more natural and functional approach to protein formulation. Kind bars, for example, often use soy protein isolate to boost protein content, especially in their Protein MAX line, which can reach up to 20 grams of protein.
However, soy protein isolate is a processed ingredient and not a whole food, which may be less desirable if you're avoiding additives or prioritizing digestibility. Mezcla uses a plant-based protein blend of pea and quinoa to deliver a complete protein profile, but typically contains only 10 grams of protein per bar.
While Mezcla is suitable for plant-based diets, its protein content is lower, and its plant proteins may not be as bioavailable as RxBar’s egg whites. This can be especially beneficial if you have dietary sensitivities, prefer minimal processing, or want to avoid common allergens like soy or dairy found in other protein bars.
RxBar markets its products as gluten-free gluten-free label, based on compliance with FDA guidelines, which permit formulations that contain less than 20 parts per million of gluten to carry the gluten-free label.
This approach reflects adherence to a regulated, external standard rather than relying on the brand’s definitions. RxBar claims to use ingredients such as egg whites, dates, and nuts, and intentionally avoids gluten-containing grains like wheat, barley, and rye.
As RxBar avoids gluten-containing grains and processed additives, its products are more likely to align with a gluten-free diet without requiring you to closely inspect each label for hidden sources of gluten. This can save time and add confidence to your food choices, especially when selecting items for regular use.
The official RxBar website provides ingredient and nutrition details for its protein bars, but does not mention any third-party testing or independent quality certifications. This absence can be a notable limitation for the brand, especially if you prioritize verified transparency, safety, and consistency in packaged food products.
Without third-party testing, there is no independent verification that RxBar products are free from contaminants like heavy metals, pesticides, or allergens.
While the ingredient list may appear clean and minimal, you’re relying entirely on the company’s internal standards and claims.
The lack of certifications such as NSF, USP, Non-GMO Project, or USDA Organic means RxBar isn’t held to documented third-party manufacturing or sourcing standards. This could mean a greater risk of variability in quality, particularly if you rely on these bars regularly or have specific dietary sensitivities.
Mezcla is a plant-based, flavor-forward protein bar brand, while RxBar focuses on performance, simplicity, and higher protein density. Both fall into the premium snack category, but they cater to different user needs, from dietary preferences and taste to availability and use cases.
In terms of pricing, Mezcla’s 8-bar Variety Pack costs $24.99, averaging about $3.12 per bar. It's 12-bar single-flavor packs featuring options like Maple Blueberry, Pistachio Chocolate, and Almond Butter Chocolate are priced at $32.99, or about $2.75 per bar.
With a 10% subscription discount, Mezcla’s cost can drop to around $2.48 to $2.79 per bar. Each bar contains 10 grams of pea protein. RxBar, on the other hand, offers a 12-bar Variety Pack for $28.99, which comes to roughly $2.42 per bar.
Single-flavor 12-packs such as Peanut Butter, Blueberry, and Chocolate Sea Salt are slightly lower at $27.99, or about $2.33 per bar. Each RxBar delivers 12 grams of egg white protein, making it more protein-dense and slightly more cost-effective per gram of protein than Mezcla.
When it comes to flavor approach, Mezcla differentiates itself with globally inspired, unconventional flavors such as Matcha Vanilla, Hot Chocolate, and Hazelnut Chocolate. RxBar sticks to familiar combinations like fruit and nut blends, which appeal to a broad base but can feel repetitive.
Mezcla is still building its retail presence. It’s available in select locations like Whole Foods and Albertsons but depends more on direct-to-consumer sales through its website, making it less accessible for the average buyer. RxBar, meanwhile, its distribution reach is significantly broader. Its acquisition by Kellogg’s has positioned it in major retail chains, including Target, Walmart, Whole Foods, and Amazon, making it readily available.
Mezcla claims to offer creative flavors, lighter texture, and plant-based appeal, while RxBar prioritizes protein content, straightforward ingredients, and wide availability.
Kind Snacks presents a broader and more varied alternative to RxBar, especially when comparing price, product range, and retail accessibility. The brand’s lineup extends beyond protein bars to include Nut Bars, Healthy Grains Bars, Zero Added Sugar Bars, and even Frozen Treats. These offerings include Cranberry Almond, Caramel Almond and Sea Salt, Peanut Butter Dark Chocolate, and Nut. It also offers Kind Kids Bars, which are smaller, nut-free options designed for children and available in flavors like Blueberry muffin and Chocolate Chip. These additions make Kindmore suitable for households with different age groups or dietary needs. Kind Snacks products are available for purchase through multiple channels like, Amazon and Instacart.
RxBar’s range, on the other hand, is more limited, focusing primarily on its standard protein bars. While it has expanded into Nut Butter & Oat Bars and Mini Bars, these are variations of its original concept rather than distinct new product lines. The oat-based bars like Blueberry Cashew butter and Dark Chocolate Peanut Butter offer around 10 grams of protein and a softer texture, while the minis are half-sized versions with about 6 grams of protein.
There are noticeable differences in user experience and branding. RxBar uses uniform, minimalist packaging that lists key ingredients prominently on the front, aiming at ingredient-conscious users.
Kind takes a more visual approach with colorful packaging and flavor-focused labeling across its products, including snack bars for adults and kids. The brands also differ in how they position themselves as RxBar centers on high-protein, performance-based snacking, while Kind spans multiple use cases, including everyday snacking, breakfast, and children’s lunchboxes.
Kind offers a wider selection, lower pricing, products suitable for kids, and more flexible snacking options, while Rx Bar is focused on high-protein bars with minimal ingredients.
RxBar was founded in 2013 with a focus on creating protein bars made from a short list of whole-food ingredients like dates, egg whites, and nuts.
The brand gained attention for its minimalist packaging and ingredient transparency. In 2017, RxBar was acquired by Kellogg’s, which allowed for greater distribution while maintaining its original clean-label positioning.
On the Better Business Bureau (BBB), RxBar holds an A-rating. This suggests a generally positive standing in terms of how it handles customer complaints and conducts its business practices.
However, the brand is not BBB-accredited, which may indicate it does not actively engage with the platform beyond resolving occasional issues. Still, the available data shows that the brand does not have a pattern of unresolved complaints.
RxBar does not currently have a profile on Trustpilot, meaning customer feedback is limited on that specific platform. This lack of presence might reduce visibility for consumers who rely on Trustpilot to evaluate brands.
On Tenereteam, RxBar has received a rating of 4.7 out of 5 based on 7 reviews. This suggests overall satisfaction from a small group of users, particularly in areas like taste, ingredient quality, and convenience.
While RxBar has established itself as a recognizable brand within the clean-label snack market, the overall public review footprint remains somewhat limited. The brand receives favorable ratings where available, but the low volume of reviews and absence from major platforms like Trustpilot make it harder to assess long-term customer satisfaction across a broader audience.
To evaluate RxBar, we closely analyzed verified customer reviews of its protein bars from Amazon, primarily from 2024 and 2025, focusing on repeated themes around ingredient quality, flavor, texture, convenience, and pricing.
Most customers emphasized the brand’s focus on simple, whole-food ingredients, typically egg whites, dates, and nuts, clearly listed on each bar. Reviewers appreciated the transparency and minimalism of the ingredient list, aligning with RxBar’s formulation approach. Several users confirmed that each bar consistently delivered 12g of protein and served as a reliable on-the-go snack, especially during workouts, travel, or busy schedules.
Taste was generally well-received, particularly for flavors like Chocolate and Chocolate Sea Salt. While the bars were often described as chewy and sticky, sometimes uncomfortably so, this texture was largely seen as a result of using only a few natural ingredients. Some users cautioned that the stickiness could be an issue for those with dental sensitivities.
We also noted feedback about affordability and packaging. Customers often considered the bars fairly priced (e.g., around $1.50 per bar). Customer reviews from the past year suggest that RxBar effectively meets the expectations of people seeking a clean-label, protein-rich snack, though the chewy texture remains a common drawback. Our evaluation is grounded in recurring user experiences shared over multiple purchases and locations, providing a balanced view of the brand’s strengths and limitations.
RxBar focuses on minimal ingredients and clear labeling. It has marketed its products as high-protein snacks made with a short list of whole foods. Packaging highlights these ingredients on the front, which the brand positions as a response to consumer concerns about overly processed products.
The brand states that it offers convenient, clean-label options without added sugars, artificial flavors, soy, dairy, or gluten. Its primary protein source, egg whites, contains all essential amino acids and is known for high bioavailability, which may support your protein needs more efficiently.
Despite this positioning, RxBar has several limitations. It does not provide third-party testing or certifications, so there is no independent verification of product purity or allergen control. The brand uses multiple major allergens across its product range, but does not disclose whether its manufacturing facilities are allergen-controlled.
If you are considering the RxBar brand, you should evaluate its ingredient approach alongside the absence of independent quality standards and the limited transparency around allergen handling.
