Best Low Carb Nut-Free Gluten-Free Protein Bars

MOSH Peanut Butter Chocolate Crunch leans into the classic pairing of real peanuts and unsweetened chocolate, but its engine is a dairy trio: whey isolate, whey concentrate, and grass-fed milk protein isolate.

To keep sugar low without a chalky texture, it uses soluble tapioca fiber (a refined fiber from cassava) for body, a little agave and vegetable glycerin for moisture, and stevia and monk fruit (concentrated plant sweeteners) with erythritol (a zero-calorie sugar alcohol) for sweetness.

Most of the calories come from peanuts and cocoa butter rather than added seed oils, which lends richness without feeling heavy. A small 'Brain Blend' adds citicoline, lion’s mane, and ashwagandha, plus vitamin D3 for a 15% daily value bump.

Altogether it’s 21 ingredients, with about five modern bar 'helpers' keeping the texture soft and the sugar in check.

Perfect Keto’s Salted Caramel goes all-in on keto: fat-forward, carb-light, and gently sweet. The protein is grass-fed bovine collagen, and the short label—about six core ingredients plus two functional helpers—leans on almond butter, cacao butter, and MCT oil for creamy, steady fuel.

Carbs are mostly from soluble fibers that give structure without the syrupy surge. Stevia provides the sweetness, while sea salt and natural flavors finish the caramel note.

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.

David Protein’s Blueberry Pie is unabashedly engineered for efficiency: 28g of protein in 150 calories, built on milk protein isolate with help from whey concentrate, egg white, and a bit of collagen.

Carbs are kept in check using a mix of refined sweeteners—maltitol (a sugar alcohol), allulose (a very low‑calorie sugar), and glycerin (a plant‑derived syrup for softness)—plus a small amount of tapioca starch for structure.

The fat stays unusually low thanks to EPG, a modified plant fat designed to provide creaminess with fewer absorbable fat calories. And despite the name, there aren’t blueberries here; the “pie” experience comes from flavors, a touch of citric acid, and color from pea flower extract and carmine.

Expect a short roster of additive helpers (about six) that make this bar read more lab‑built than pantry‑made—by design.

BHU Foods’ Peanut Butter Chocolate Chip Cookie Dough bar is a keto‑leaning, fully plant‑based recipe built around organic pea protein and peanuts. It skips added sugar in favor of monk fruit and uses soluble tapioca fiber—a cassava‑derived fiber that gives the doughy chew—to bind everything together.

Calories come mostly from peanuts, cocoa butter, certified‑sustainable red palm oil, and coconut‑based MCTs, for 260 calories with 13g of protein and 1g of sugar.

The label stays short, with two functional helpers (sunflower lecithin for stability, monk fruit for sweetness), and the flavors read like your pantry: roasted peanut, vanilla, dark‑chocolate chips with a quiet lift from baobab.

Mint Chocolate Chip from Love Good Fats plays the candy-bar role - real cocoa, a chocolatey coating, and mini chips - yet keeps sugar low by using erythritol (a low-calorie sugar alcohol), stevia (a plant sweetener), and chicory-root fiber (a prebiotic that adds body).

Protein comes from a hybrid blend: pea protein plus whey protein isolate, with a small hit of brown rice protein in the coating, for broad amino-acid coverage with minimal lactose, but it lands at a snack-like 9 grams.

It's intentionally higher-fat and lower-sugar, built on sunflower-seed butter, palm and coconut oils, and cocoa butter for that creamy snap at 190 calories. Expect roughly five functional add-ins to keep sweetness, softness, and structure in line, typical of keto-style recipes even if this one isn't strict keto.

Peanuts really lead here—whole peanuts, peanut butter, and a little peanut flour—while cocoa powder and chocolate chips sweetened with xylitol (a sugar alcohol) bring the chocolate. The protein is fully plant-based (a pea-and-rice blend), set inside a higher-fat, lower-carb recipe that leans more on refined syrups for sweetness than fruit.

You taste genuine richness from peanut oils, with shea and cocoa butter giving structure, and chicory root fiber helping keep the carb load restrained. The extras are restrained too—think sunflower lecithin for smooth chocolate and antioxidant vitamins C and E—so it reads more pantry than science project.

Keto Bars’ Chocolate Peanut Butter sticks to the headline: real peanut butter and chocolate, with coconut for chew and richness. It’s a plant-protein bar because the protein comes from peanuts, so the texture is soft and nutty rather than shake-in-a-wrapper chewy.

The ingredient list is short—peanut butter, chocolate, coconut, water, and salt—with two sweeteners (erythritol, a sugar alcohol, and a pinch of stevia) standing in for sugar. Fats from peanuts, coconut, and the cocoa butter in chocolate do most of the fueling, which is why a small bar feels surprisingly satisfying without a syrupy crash.

FITCRUNCH Apple Pie centers on a whey-forward blend that packs 16g of protein into a layered, candy-bar-style bite.

Carbs land at 14g and sugar at 3g because sweetness leans on sugar alcohols and glycerin rather than fruit or oats, while fat is a bit higher at 10g from palm-based oils that give those layers structure.

The apple-pie profile comes from cinnamon, brown sugar, molasses, vanilla, and natural flavors—nostalgic, even without visible apple pieces. It’s also one of the more engineered options here, with roughly 50 ingredients and 17 functional additives to keep the texture soft, cohesive, and shelf-stable.
