RXBARs Macros: Complete Nutrition Facts for All Flavors

Reviewed by Dr. Michael Torres, PhD

RXBAR protein bars showing whole food ingredient list and macro nutrition label

RXBARs took the protein bar market by storm with radical transparency: the wrapper lists exactly what’s inside. “3 Egg Whites, 6 Almonds, 4 Cashews, 2 Dates, No B.S.” It’s refreshing in a category full of mystery ingredients and unpronounceable additives.

But whole food ingredients don’t automatically mean optimal macros. RXBARs prioritize ingredient quality over macro efficiency, resulting in a bar with decent protein (12g) but significant sugar (12-15g) from dates. Understanding this trade-off helps you decide if RXBAR belongs in your nutrition plan.

This guide covers every RXBAR flavor’s complete nutrition facts, compares them to competitors, and explains when whole food bars make sense for your goals.

RXBAR Macro Overview

All RXBARs share similar macros with minor variations:

MetricRange Across Flavors
Calories200-220
Protein12g
Total Carbs22-24g
Fiber4-6g
Sugar12-15g
Fat9-11g

Key insight: The 12-15g sugar comes entirely from dates—no added refined sugar. But natural sugar still affects blood sugar and counts toward daily intake. RXBARs are cleaner, not lower-sugar.

RXBAR Ingredients Deep Dive

What sets RXBAR apart is ingredient simplicity:

Core ingredients (all flavors):

  • Egg whites (protein source)
  • Dates (binder, sweetness)
  • Almonds and/or cashews (fat, texture)
  • Natural flavors

Chocolate flavors add:

  • Cacao
  • Cocoa

That’s it. No protein isolates, no fiber syrups, no sugar alcohols. The trade-off is higher sugar and lower protein compared to engineered bars.

Protein Quality

Egg white protein is highly bioavailable with excellent amino acid profile. The 12g in RXBAR is quality protein, even if quantity is lower than competitors.

Sugar Reality Check

The 12-15g sugar isn’t “healthier” because it’s from dates—it’s just less processed. Your body metabolizes date sugar similarly to other sugars. The difference is you’re getting fiber and micronutrients alongside it.

Where to Buy RXBARs

RXBARs are widely available (owned by Kellogg’s):

Best prices:

  • Costco: 14-count boxes at ~$1.50/bar
  • Amazon Subscribe & Save: ~$1.75-2.00/bar

Pro tip: RXBAR frequently offers variety packs—great for trying flavors before committing to full boxes.

Diet Compatibility

Keto Diet

Verdict: Not compatible 18-20g net carbs per bar exceeds most keto daily limits. The date sugar will spike blood glucose. Avoid on keto.

Paleo Diet

Verdict: Excellent RXBARs are essentially paleo-compliant: egg whites, nuts, dates, and natural flavors. One of the most paleo-friendly protein bars available.

Whole30

Verdict: Compliant (with caveats) RXBARs are technically Whole30 compliant, but the program discourages using bars as meal replacements. Use sparingly for emergencies.

Low-Calorie/Weight Loss

Verdict: Moderate 210 calories with 12g protein isn’t terrible, but the sugar content may not satisfy cravings as well as lower-sugar options. Whole foods still better.

Use our macro calculator to see how RXBAR fits your daily targets.

Low-Sugar Diets

Verdict: Not recommended 12-15g sugar per bar is significant. Even though it’s from dates, it’s still sugar. Choose Quest or Barebells if limiting sugar.

Vegetarian

All RXBARs are vegetarian (contain egg whites, no meat).

Vegan

Not compatible. Egg whites are core ingredient. Look for plant-based alternatives.

Gluten-Free

All RXBARs are certified gluten-free. Safe for celiac disease.

How to Fit RXBARs in Your Macros

1,600 calorie cut (130g protein):

  • RXBAR = 210 cal, 12g protein, 13g sugar
  • 13% of calories for 9% of protein
  • Sugar adds up—not ideal for strict cuts

2,000 calorie maintenance (150g protein):

  • RXBAR = 210 cal, 12g protein
  • 10.5% of calories for 8% of protein
  • Reasonable occasional snack

2,500 calorie active lifestyle:

  • RXBAR works well as clean-ingredient energy
  • Sugar less concerning with higher activity
  • Good hiking/travel bar

When RXBARs Make Sense

Good uses for RXBARs:

  • Paleo/Whole30 compliant eating
  • Avoiding artificial ingredients
  • Moderate protein needs
  • Travel and emergencies
  • Post-workout with carb needs

Not ideal uses:

  • Strict keto or low-carb
  • Minimizing sugar
  • Maximum protein efficiency
  • Weight loss focused eating

The RXBAR Philosophy Trade-Off

RXBAR represents a choice: whole food ingredients over optimized macros.

What you get:

  • Simple, recognizable ingredients
  • No artificial sweeteners
  • No protein isolates
  • Paleo/Whole30 friendly

What you sacrifice:

  • Higher protein (Quest: 21g vs RXBAR: 12g)
  • Lower sugar (Quest: 1g vs RXBAR: 13g)
  • Lower net carbs (Quest: 5g vs RXBAR: 18g)

Neither approach is wrong—they serve different priorities.

Choose RXBAR when:

  • Ingredient quality matters more than macro optimization
  • You’re following paleo or Whole30
  • You prefer whole food sources
  • Sugar isn’t a strict concern

Skip RXBAR when:

  • You need maximum protein per calorie
  • You’re limiting sugar intake
  • You’re on keto or strict low-carb
  • Macro efficiency is priority
