RXBAR vs LaraBar (2026): 12g vs 4g Protein Per Bar — What You're Actually Paying For

RXBAR and LaraBar are both marketed as clean-label, minimal-ingredient bars built on dates and nuts. They sit in the same grocery shelf section, target the same shopper who cares about ingredient lists, and often get compared directly because they are the two most visible brands in the “real food” bar category. But they are doing very different nutritional jobs — and the difference is entirely about what each brand puts in the bar alongside the dates.

LaraBar keeps it to dates, nuts, and fruit. RXBAR adds egg whites. That one change is why one bar delivers 12g of protein and the other delivers 4–5g, at almost identical calorie and sugar counts. Everything else in the comparison follows from that.

RXBAR vs LaraBar: Side-by-Side Comparison Table

All figures per labeled serving (one bar). RXBAR figures are for the Chocolate Chip flavor (52g bar). LaraBar figures cover two representative flavors — Peanut Butter Chocolate Chip (45g) and Apple Pie (45g) — because the nutrition varies meaningfully between fruit-nut-only flavors and nut-butter flavors. Sources: Kellogg SmartLabel (RXBAR Chocolate Chip, verified October 2026); retailer panel listings for LaraBar flavors (verified October 2026).

LaraBar PB Chocolate Chip note: the semisweet chocolate chips in this flavor contain milkfat, making it not vegan despite being otherwise plant-based. The Apple Pie and most other fruit-nut LaraBar flavors are vegan-friendly. Always confirm the label if vegan compliance is required.

Why the Protein Gap Is So Large

A natural bar built on dates and nuts will always deliver roughly 4–6g of protein per 45–55g bar. That is the ceiling you get from dates plus almonds or cashews without adding a dedicated protein source. Dates are about 2g of protein per 100g. Almonds are 21g of protein per 100g, but a bar this size only has 15–20g of almonds in it. The math tops out at 4–6g no matter how many nuts you add before the bar gets too calorie-dense.

RXBAR broke that ceiling by adding egg whites. A standard bar has roughly 3–4g of dried egg whites, which contribute about 10g of protein (egg whites are roughly 11g of protein per 100g when dried). That addition, on top of the ~2–3g the nuts already provide, lands the bar at 12g total.

The reason this matters: egg white is a complete protein — it contains all nine essential amino acids including tryptophan and adequate leucine. A bar built solely on nuts and dates delivers protein that is lower in tryptophan and methionine than a complete protein source. For everyday fitness use this difference is small if you are eating a varied diet. For anyone specifically targeting protein for muscle repair or trying to close a daily protein gap, the 12g complete protein RXBAR provides is meaningfully more useful than the 4–5g from a LaraBar.

RXBAR Chocolate Chip — The Protein Bar for Clean-Label Shoppers

The case for RXBAR: it is one of the most protein-efficient “real food” bars on the market. Most clean-label bars sacrifice protein to keep a short ingredient list; RXBAR does not. The seven ingredients are all recognizable: dates, egg whites, almonds, cashews, chocolate, natural flavors, sea salt. No whey isolate, no milk protein concentrate, no sugar alcohols, no artificial sweeteners. The 12g of protein comes from a natural food source (egg whites) rather than a processed protein isolate.

The bar is dense and chewy — the dates bind to the nuts and dried egg whites — and the Chocolate Chip flavor is sweet in a way that tastes like a date square rather than a candy bar. Other popular flavors include Blueberry (12g protein, similar macros), Mixed Berry, and Peanut Butter. All mainstream flavors deliver 12g of protein per bar with minor variations in calories (190–220) and sugar (13–18g) depending on inclusions. See our RXBAR nutrition facts guide for a full flavor-by-flavor breakdown.

The honest limitations: RXBAR is not vegan (egg whites are an animal product). The 210mg of sodium in the Chocolate Chip flavor is the highest figure in this comparison — fine for most people, but worth noting if you are monitoring sodium. At $2.25–$2.99 per bar depending on format and retailer, it is $0.50–$1.00 more expensive than a LaraBar. And at 5.7g of protein per 100 calories, it is still far below what a dedicated protein bar like Quest (11.1g / 100 cal) or DAVID (18.7g / 100 cal) delivers — its protein efficiency is better than LaraBar but not in the same league as protein-engineered bars.

LaraBar — The Cleaner Ingredient List, at Lower Protein

The case for LaraBar: LaraBar has the shortest ingredient list in the bar category. The Apple Pie bar has six ingredients: dates, almonds, unsweetened apples, walnuts, raisins, cinnamon. The Cashew Cookie bar has two: dates and cashews. The Peanut Butter Chocolate Chip bar has five. No flavoring agents, no egg whites, no protein concentrates. If the reason you want a clean-label bar is to minimize processing and recognize every ingredient, LaraBar goes further in that direction than RXBAR does.

LaraBar is also the default pick for plant-based eaters. Most flavors are vegan, gluten-free, dairy-free, and soy-free — the exception being flavors whose chocolate chips contain milkfat (Peanut Butter Chocolate Chip and some others). The Apple Pie, Cherry Pie, Pecan Pie, and most fruit-based flavors are fully vegan. This makes LaraBar the clean-label option for dairy-free, vegan, and allergen-restricted shoppers that RXBAR cannot serve.

The 0g added sugar is meaningful in a different way than RXBAR’s: LaraBar’s sugars come entirely from whole dates and dried fruit, with no sweetening agents of any kind. The Apple Pie bar has ~18g of total sugar, but that sugar is fructose from dates, raisins, and dried apple — the same sugar that is in those fruits when you eat them whole.

The honest limitations: at 4–5g of protein per bar, LaraBar is not a protein bar — it is a fruit and nut bar. Calling it a protein bar or expecting it to close a protein gap is a mismatch. It is also calorically dense (190–220 calories per 45–48g bar) relative to its protein, which means it is not an efficient protein source. The fat content (9–12g per bar) is also the highest in this comparison — the nuts provide both the fat and what little protein LaraBar delivers. If your goal is specifically to add protein, RXBAR or a mainstream protein bar is the more efficient choice at the same calorie cost.

Is the Sugar in These Bars a Problem?

Both bars show 17–18g of total sugar, and both show 0g of added sugar. That combination surprises some shoppers, so it is worth explaining.

Dates, the primary ingredient in both bars, are naturally very high in fructose and glucose. A single Medjool date contains roughly 16g of sugar. Both brands are basically “date bars” at their core, and those 17–18g of sugar are entirely from the dates (and in RXBAR’s case, a small amount from the chocolate chips). No table sugar, no cane juice, no honey — zero added sugars, just the natural sugar already in the fruit.

Whether this matters for your goals depends on context. For glycemic response, the fiber in these bars (3–4g per bar) moderates the glucose spike versus eating plain dates. For total daily sugar intake, 17g in one bar is meaningful if you are actively limiting sugar. For blood sugar management specifically (type 2 diabetes or pre-diabetes), both bars warrant the same caution as any other fruit-sweetened food — neither is a sugar-free option.

Which Bar Should You Buy?

Frequently Asked Questions

Is RXBAR better than LaraBar?

It depends entirely on what you want from a bar. RXBAR is better if protein content is the priority — 12g per bar versus LaraBar’s 4–5g at the same calorie count. LaraBar is better if you want the shortest ingredient list, a fully plant-based option (most flavors), lower sodium, or a lower cost per bar. Both bars use dates as the primary ingredient and carry zero added sugars.

How much protein does RXBAR have vs LaraBar?

RXBAR Chocolate Chip delivers 12g of protein per 52g bar at 210 calories. LaraBar Apple Pie delivers 4g of protein per 45g bar at 200 calories. LaraBar Peanut Butter Chocolate Chip delivers 5g per 45g bar at 210 calories. RXBAR delivers roughly three times as much protein as a standard LaraBar flavor, because RXBAR includes egg whites alongside the nuts — LaraBar uses only nuts and fruit. Both figures verified from published nutrition label data, October 2026.

Is RXBAR vegan?

No. RXBAR uses dried egg whites as its primary protein source, which makes it unsuitable for vegans. Most LaraBar flavors are vegan — but not all. Flavors with chocolate chips (Peanut Butter Chocolate Chip, Double Chocolate Chip, others) contain milkfat in the chocolate and are not vegan. LaraBar fruit-and-nut flavors (Apple Pie, Cherry Pie, Pecan Pie, Cashew Cookie, and most others) are vegan. Check the allergen statement on the specific flavor you are buying. For a 20g-protein vegan protein bar, see our best vegan protein bars guide.

Does LaraBar count as a protein bar?

Not in the conventional sense. Most mainstream protein bars deliver 15–28g of protein per bar as their primary selling point. LaraBar delivers 4–6g — comparable to eating a small handful of mixed nuts. LaraBar is a fruit-and-nut bar, not a protein bar; it provides a convenient, clean-ingredient snack with dates and nuts, not a meaningful protein supplement. If you are buying it expecting a protein hit, you are buying the wrong product. If you want a low-ingredient, whole-food bar with no added sugar, LaraBar excels.

Are RXBAR and LaraBar good for weight loss?

Both bars sit at 190–220 calories with zero added sugar, which makes them cleaner choices than candy or processed snack bars for most weight-loss contexts. RXBAR’s higher protein (12g) offers more satiety per calorie than LaraBar’s 4–5g. Neither bar is low-calorie — both are calorie-dense relative to their volume because dates and nuts are energy-dense foods. On a calorie-controlled diet, a single bar of either fits, but neither brand’s calorie density is particularly conducive to volume eating. See our best protein bars for weight loss guide for options with higher protein and lower calories.

Which has less sugar — RXBAR or LaraBar?

Total sugar is nearly identical: RXBAR Chocolate Chip has 18g of total sugar; LaraBar Apple Pie has ~18g; LaraBar Peanut Butter Chocolate Chip has ~17g. Both have 0g of added sugar. The sugars are almost entirely from dates in both cases. The Chocolate Chip flavor of RXBAR has a small amount of sugar from the chocolate inclusion. If you are comparing on added sugar specifically, both bars are at zero — the tie on added sugar means this criterion does not differentiate them.

Bottom line: buy RXBAR if you want the most protein from a clean-label, whole-food bar — 12g from egg whites, almonds, and cashews at 210 calories with zero added sugar. Buy LaraBar if you want the shortest ingredient list, a plant-based option, lower sodium, or a lower cost per bar. Neither bar is competing with Quest, Barebells, or DAVID on protein density — they are in the clean-ingredient bar category, not the high-protein bar category.
