TL:DR

In 2 Sentences

A REESE’S‑branded, candy‑bar‑style protein bar that keeps sugar to 3g while delivering 18g of dairy protein and a soft, dessert‑leaning texture.

When to choose ONE Brands REESE'S Peanut Butter Lovers

Best for peanut‑butter diehards who want a gluten‑free, vegetarian‑friendly protein snack that feels indulgent after a workout or as a 3pm sweet‑tooth fix.

What's in the ONE Brands bar?

Peanut‑butter lovers, this one reads like dessert but plays in the protein aisle.

ONE’s REESE’S Peanut Butter Lovers flavored bar gets its 18 grams of protein from a dairy blend—milk protein isolate plus several forms of whey—then layers on peanuts, peanut flour, and partially defatted peanuts for that classic peanut‑butter punch.

The carbs sit on the higher side for bars (around the 80th percentile) and come mostly from refined fiber syrups and sugar‑alcohol sweeteners rather than oats or dates, which can smooth sugar spikes but may bother sensitive stomachs.

Fats are a mix of nut‑derived unsaturated fats and palm‑based confectionery fats that keep the bar firm; calories land in the higher range for bars too. Net effect: a candy‑bar‑style experience with above‑average protein and low sugar, built with a modern ingredient toolbox.

  • Protein

    MID

    Protein comes mainly from milk protein isolate—physically filtered skim milk that retains both casein and whey with very little lactose—supported by whey isolate, concentrate, and hydrolyzed whey for quick‑digesting amino acids. Peanuts and peanut flour contribute a smaller plant‑protein boost. At 18 grams (above average for bars), you get a blend that’s both steady (casein) and fast (whey).

  • Fat

    11
    9
    MID

    Fat is split between nuts and confectionery fats: peanuts (and a touch of almonds) bring mostly unsaturated fats, while palm kernel oil and hydrogenated vegetable oil (from palm kernel and soybean) supply solid, saturated structure that keeps the bar stable. Soybean oil adds omega‑6 polyunsaturates. The result is a mixed profile—nutty and nutritious on one side, more saturated from palm‑based fats on the other.

  • Carbs

    25

    HIGH

    These are engineered, not grain‑based carbs. Most come from soluble corn fiber and isomalto‑oligosaccharides (refined fiber‑like syrups) plus glycerin for moisture and maltitol, a sugar alcohol, for bulked sweetness, with small amounts of corn‑syrup solids and tapioca starch for quick glucose. Expect a steadier rise than straight sugar overall, though the quick carbs are still there—and those sensitive to polyols/fibers may want to test their tolerance.

  • Sugar

    3
    4
    MID

    Sugar stays low at 3 grams because sweetness leans on maltitol (a lower‑calorie sugar alcohol) and a tiny dose of sucralose (an artificial, zero‑calorie sweetener), with minimal sugar and some lactose from dairy. That means less classic sugar, not fruit‑derived sweetness. If you’re sensitive to sugar alcohols, the low sugar won’t necessarily mean kinder digestion.

  • Calories

    HIGH

    At 250 calories (on the higher end for bars), energy is shared across macros: protein provides a solid chunk, with the rest coming from peanut/palm‑based fats and carbohydrate syrups/sweeteners. The label lands at 250 because some carbs here—sugar alcohols and resistant fibers—count fewer calories per gram than sugar. It eats like a satisfying snack or small meal rather than a light bite.

Vitamins & Minerals

No standout fortification here: you get modest calcium (about 6% DV) from the milk proteins and skim milk, plus small amounts of iron and potassium likely from peanuts and almonds. Think of this bar as protein‑and‑flavor first, micronutrients second.

Additives

Expect a modern bar toolkit: soluble corn fiber and isomalto‑oligosaccharides for chew and fiber, glycerin to keep it soft, soy lecithin to emulsify, and sucralose to fine‑tune sweetness. These are highly refined ingredients chosen to deliver a candy‑bar texture with low sugar. It’s effective, though the polyol‑and‑fiber combo can be gassy for sensitive guts.

I LOVE ONE BARSSS I converted because they don’t give me acid reflux on my run. I have one about 20-40min before and it’s just simply such a worry and pain-free run without being hungry or worrying about my burp bringing up a surprise. I love the maple glazed donut and birthday cake. Just got a variety box on Amazon to try the other flavors. They’re perfectly sweet, not too much not too little.

Main Praise

Fans say it tastes like a treat, not a compromise. Across thousands of Amazon ratings (4.

3 average), people call out the peanut‑butter flavor and the lack of “cardboard” you brace for in most high‑protein bars. Editors at Men’s Health and Prevention routinely praise ONE bars for strong macros with low sugar, and BarBend’s reviewer even named them a favorite in taste tests.

In the wild, runners and lifters report it sits well and actually satisfies—enough chew to feel like food, not taffy. Compared with some competitors, it’s sweet without a heavy artificial aftertaste, which is why many keep it in the gym bag.

Main Criticism

Not every bite is love at first chew. A few Redditors call the texture “pasty” or “dry,” and one peanut‑butter‑cup pessimist went dramatic with “tastes like dog food”—probably more about flavor expectations than the bar, but still.

Others prefer the taffy‑like pull of Quest and find ONE a bit crumbly. The sweetener play—maltitol (a sugar alcohol) plus a touch of sucralose—keeps sugar low but can bother sensitive stomachs when combined with refined fiber syrups.

It’s also pricier than basic bars and uses a longer, more processed ingredient list, including palm‑derived fats.

The Middle Ground

Here’s where the truth probably lands: if your goal is “peanut‑butter‑candy‑bar energy” with meaningful protein and minimal sugar, this fits. The dairy blend offers a mix of fast and slow‑digesting protein, while peanuts and confectionery fats create that familiar, candy‑bar bite.

But engineering has a texture tax; some taste buds translate the fiber‑and‑protein matrix as pasty. Reddit user unknown’s “soap” take is loud but not common; palates, as always, are personal.

The sugar strategy is a trade‑off too: fewer grams from sugar, more reliance on sugar alcohols and refined fibers—great for glucose steadiness, not great for every gut. And remember the scale: at 250 calories, it’s a real snack or light meal, not a nibble.

If you want short‑ingredient, fruit‑sweetened simplicity, look elsewhere; if you want dessert energy with better macros, this is almost the point of ONE.

What's the bottom line?

ONE Brands’ REESE’S Peanut Butter Lovers delivers on the promise most people actually want: a peanut‑butter‑forward, candy‑bar‑style bite with 18g of protein and just 3g of sugar. It’s gluten‑free and vegetarian‑friendly, and it leans on modern food science—fiber syrups, sugar alcohols, and stabilizing fats—to make the texture and sweetness happen. For peanut‑butter fans who measure snacks in satisfaction, it’s an easy win—especially post‑workout or whenever the sweet tooth clocks in.

Just know your stomach; sugar alcohols aren’t for everyone, and ingredient minimalists will prefer a simpler bar. Allergens are clear: milk, peanuts, soy, and almonds. Try a single bar before buying a case and you’ll know quickly which camp you’re in.

Listicle take: Candy‑bar peanut butter flavor with 18g protein and 3g sugar. Great for peanut‑butter lovers seeking a satisfying post‑workout or 3pm fix. Heads up: relies on sugar alcohols and refined fibers, which can bother sensitive stomachs.
