Best Low Calorie Wheat-Free Vegetarian Protein Bars

Promix's Snickerdoodle builds its structure around airy whey protein puffs, then binds them with a cinnamon-vanilla marshmallow layer. It is intentionally light at 150 calories with 15g of complete dairy protein and very little fat, so it eats like a snack rather than a meal.

Carbs lean refined, with cassava-derived tapioca syrup and tapioca starch, tempered by added soluble fibers from tapioca and chicory-root inulin to keep sugars modest. You will also see a few functional helpers used sparingly, like sunflower lecithin to keep the puffs crisp and agar and glycerin to set and soften the marshmallow.

The result is a dessert-spice profile with a cereal-like crunch rather than a sticky chew.

This light 140‑calorie Salted Caramel bar leans on dairy proteins—casein first, then whey concentrate—for its backbone.

Chew and sweetness come from cassava‑derived tapioca fiber and a bit of tapioca starch, paired with allulose (a low‑calorie sugar) and a touch of glycerin (a plant‑based syrup) to keep it soft.

Fat is mostly almond butter with some palm oils and a little cream, which also helps deliver that salted‑caramel feel alongside natural flavor and a pinch of salt.

Instead of sugar or dates, it uses alternative sweeteners—mostly allulose with tiny amounts of stevia and monk fruit—so you get 1 gram of sugar and a candy‑bar texture, achieved with a modest list plus a few modern additives.

David Protein’s Chocolate Chip Cookie Dough bar is unmistakably protein-first: a blend led by milk protein isolate with whey, egg white, and a bit of collagen drives 28 grams of protein—unusually high for a 150‑calorie bar.

The sweetness and soft chew come mostly from engineered sweeteners rather than fruit or grains: a sugar alcohol, a low-calorie sugar, and a plant-based syrup provide sweetness and moisture with fewer calories than table sugar, supported by a small amount of tapioca starch (from cassava).

Fat stays intentionally low; coconut oil and cocoa butter are joined by EPG, a modified plant fat designed to feel creamy while contributing fewer digestible calories than regular oils. Flavor cues—unsweetened chocolate, Dutch-process cocoa, and peanut flour/extract—pull the doughy, bakery note together.

Count on a designed recipe: six functional additives within a 19‑ingredient list, prioritizing performance over a short, whole‑food panel.

Orgain’s Peanut Butter Protein Bar leans on plants: a blend of organic brown rice protein and pea‑protein crisps provides the lift, with peanuts and ground chia rounding it out.

It’s a lighter, 150‑calorie bar whose carbs come from refined tapioca syrup, balanced by soluble tapioca fiber (a resistant fiber) and a small amount of erythritol to keep sugars down and the chew soft.

The peanut taste comes from organic dry‑roasted peanuts, not just natural flavor.

Fats skew unsaturated from nuts and seeds, including a touch of omega‑3 ALA from chia, with only a few functional helpers like glycerin and sunflower lecithin to hold it all together.

Bright lemon meets toasty coconut in a plant-based bar built on soy protein crisps. Those crisps—soy protein isolate lightly bound with tapioca—deliver complete vegan protein while keeping the texture light and snappy.

Energy comes from oats and brown‑rice crisps, steadied by chicory root fiber, with fats kept modest via cashew butter, sunflower oil, and a sprinkle of coconut. Sweetness leans on a small amount of cane sugar, rounded out by vegetable glycerin (a plant‑derived syrup that keeps bars moist) and natural flavors.

The result is a gluten‑free, dairy‑free bar with mid‑pack protein and very low sugar—more crisp snack than candy‑bar clone.

MOSH’s Chocolate Chip Cookie builds its 11g of protein from pea protein and almonds, then layers in cocoa, cocoa butter (sometimes coconut oil), maple, sea salt, and natural flavors for a cookie‑chip bite.

It’s a light 160‑calorie bar with moderate fat from nuts and cocoa butter and carbs that lean on soluble tapioca fiber (a refined, non‑digestible fiber from cassava) and allulose (a low‑calorie sugar) rather than cane sugar.

In practice, that means sweetness without the syrupy crash; a tiny lift from stevia and monk fruit keeps it tasting like dessert, while small amounts of rice/tapioca starch help the bar hold together.

You also get the brand’s Brain Blend—vitamin D3 plus other nootropic add‑ins—though the amounts aren’t disclosed. The recipe reads mostly whole‑food ingredients supported by four functional helpers for texture and sweetness (a softener, an emulsifier, a refined fiber, and a low‑calorie sugar).

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.

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.

Exo builds this bar around an unusual team: cricket flour mixed with pea protein and egg whites, which together provide 14 grams of protein in a compact 160-calorie bite. The chocolate character comes from alkalized cocoa and pockets of semi-sweet chips, while most of the sweetness is handled by allulose with a small assist from monk fruit.

Carbs lean more refined, using a cassava-based syrup (prebiotic tapioca concentrate) and pea-based crisps to hold the bar together, and fats come chiefly from sunflower butter.

The ingredient list is concise for the category—roughly 18 items with just two true additives (a touch of natural flavor and soy lecithin in the chips, which simply keeps the chocolate smooth).
