Best Low Calorie Egg-Free Gluten-Free Protein Bars

Fiber One's Peanut Butter Chocolate Protein Bar plays the light-but-satisfying card: 10g protein, 10g carbs, 2. 5g fat, 1g sugar, 90 calories.

The protein base is a soy-first blend supported by whey and casein, with a pinch of collagen; flavor comes from peanut flour, real peanuts, Dutch cocoa, and a little peanut oil.

To hit those macros, it leans on five refined helpers - soluble fibers and low-calorie sweeteners that provide sweetness and chew while keeping sugars low - rather than oats or dates; most people find the energy steadier, though sensitive stomachs can notice sugar alcohols.

Fat stays minimal and mostly structural, coming from palm-derived oils with small contributions from peanuts and canola. Net-net: think tidy peanut-chocolate pick-me-up, not a meal.

Built’s Peanut Butter bar plays the greatest hit—peanut butter and dark chocolate—but builds it on whey protein isolate, including a partially hydrolyzed form that’s easy to absorb. The macros are deliberately light, with modest fat, 17g of protein, and carbs that lean more on refined fiber and modern sweeteners than sugar.

You’ll also find five common additives doing practical jobs like softening texture and supplying sweetness without a big sugar load. It’s intentionally more “engineered treat” than “minimal‑ingredient” snack, aiming for steady energy and dessert appeal in one swipe.

Magic Spoon’s Blueberry Muffin bar builds its sweetness and structure more like a smart dessert than a sticky protein brick: milk proteins (casein first, whey concentrate later) for the muscle support, freeze‑dried blueberries and natural flavor for the muffin note, and only 140 calories.

Much of the usual sugar and flour are traded for allulose—a low‑calorie sugar—and refined soluble fibers from tapioca and chicory that help keep blood sugar steadier. Fats come from almond butter, plus palm‑derived oils and a little cream, which keep the bar tender and shelf‑stable.

You’ll also see a handful of functional helpers—about five by our count—for sweetness and texture: allulose (a low‑calorie sugar), stevia and monk fruit (high‑intensity sweeteners), glycerin (a plant‑derived syrup that holds moisture), and sunflower lecithin (an emulsifier that keeps things smooth).

The result is a keto‑leaning, dessert‑styled bar that gets its sweetness mostly from modern sweeteners rather than sugar.

Orgain’s Chocolate Brownie keeps the promise in its name: real cocoa and dairy-free chocolate chips lead the flavor, not a blast of candy-bar sweetness. The protein is strictly plant-based—an organic blend of brown rice and pea crisps with a quiet boost from chia—and the whole bar clocks in at 150 calories.

Carbs skew more refined for texture and cohesion (think tapioca syrup and a fiber-like starch syrup) rather than oats or dates, while fats come mainly from almond butter with a touch of cocoa butter.

There are 17 ingredients total and four common “texture and sweetness helpers” to keep it soft and cohesive; they’re standard for low-sugar-style bars but can be noticeable if your stomach is sensitive.

SimplyProtein’s Peanut Butter Chocolate builds flavor from real peanuts and unsweetened chocolate, then holds it together with soy protein crisps—soy protein isolate puffed into crunchy bits.

The label stays tight: seven core ingredients by our count, plus three functional add-ins that lean on chicory-root inulin and acacia (plant fibers) and a touch of plant-derived glycerin (a syrup that keeps the bar soft) to keep sweetness gentle without artificial sweeteners.

Fats come mostly from peanuts, with small amounts of peanut and sunflower oils; carbs come from brown rice crisps and a little cane sugar, with those fibers adding body and mild sweetness.

It’s vegan and gluten-free, and it eats like a light, crisp snack rather than a dense meal replacement.

MOSH’s Blueberry Almond Crunch leans on a dairy trio—whey isolate, whey concentrate, and grass-fed milk protein isolate—and keeps things tight at 170 calories.

Carbs are lower than most bars and center on soluble tapioca fiber, a refined fiber from cassava root, while sweetness comes mainly from stevia and monk fruit instead of a lot of sugar.

Almonds and real blueberry bits do the flavor and texture heavy lifting.

A small 'brain blend' adds flaxseed plus a few functional extras—citicoline (a choline source), lion’s mane (a culinary mushroom), vitamin D3, vitamin B12, and ashwagandha (an adaptogen)—so it nudges into functional-snack territory without reading like a supplement.

The label uses five modern helpers to manage texture and sweetness, keeping the bar soft rather than syrupy.

Bright lemon, toasted coconut, and a creamy “white chocolate” style coating make this bar feel like a summer snack in miniature.

The protein is mostly soy protein isolate (some of it in crunchy nuggets) with a small assist from milk protein isolate in the coating, so it’s a soy-first blend with a touch of dairy.

Carbs stay low in sugar by leaning on refined fibers—chicory-root fiber (inulin/oligofructose) and soluble corn fiber—plus a bit of glycerin for softness, and stevia for sweetness. Fats come from almonds and coconut, rounded out by palm-based oils in the coating, for a mix of unsaturated and saturated fats.

There are four familiar add-ins—glycerin, sunflower lecithin, stevia, and tocopherols—to keep texture, sweetness, and freshness on point.

Promix Nutrition’s Chocolate (Plant) bar leans light and crispy: pea-protein puffs plus added pea protein deliver 10 grams of plant protein, while cocoa powder, dairy-free chips, and a chocolatey drizzle supply the dessert notes.

Carbs sit mid-range and come mostly from refined binders like tapioca syrup and cane sugar, buffered by some soluble tapioca fiber and a touch of chickpea for a steadier ride than straight sugar.

Fat stays modest at 5 grams from confectionery fats such as coconut oil and palm kernel oil in the drizzle, along with cocoa butter in the chips.

The label is vegan and gluten-free with no artificial sweeteners, and it relies on just three common helpers—glycerin for softness, sunflower lecithin to keep the chocolate smooth, and agar for structure.

Mosh’s Pumpkin Spice Chocolate Chip keeps things light and plant-forward: pea protein and almonds anchor the bar, spices and cocoa bring the fall flavor, and the brand’s Brain Blend adds 100% DV vitamin B12 and 25% DV vitamin D3.

Sweetness leans on allulose—a low-calorie sugar that tastes like sugar but barely nudges blood glucose—with tiny boosts from stevia and monk fruit.

Carbs are padded by soluble tapioca fiber, a resistant dextrin refined from cassava that adds bulk and a softer chew, rather than grains; fats come mostly from almonds with a little cocoa butter and coconut oil.

There are four functional additives to keep sweetness, softness, and mixability in line, and the whole thing lands at a very snackable 150 calories.
