Best Lowest Carb Protein Bars

Maximuscle’s Chocolate Fudge keeps things intentionally light: 94 calories and a snack‑size 7. 5g of milk‑based protein (casein and whey isolate) with a little collagen to keep the texture soft.

The chocolate taste is the real deal, built from cocoa mass, cocoa butter, and fat‑reduced cocoa powder, rounded with vanilla and a pinch of salt.

Sweetness mostly skips table sugar, leaning on maltitol (a sugar alcohol with fewer calories than sugar) plus a tiny dose of sucralose; glycerin helps it stay moist and soy lecithin keeps the chocolate smooth.

Carbs stay low and are mostly refined (rice flour and a bit of natural milk lactose), while fats lean “chocolate‑style” from cocoa and shea butter with a touch of rapeseed oil.

Power Crunch Chocolate Strawberry is built like a crisp cookie: thin wheat wafers around a creamy filling, not the usual nougat brick. Its protein comes from dairy—hydrolyzed whey plus whey and milk isolates—so it’s complete, quick to digest, and relatively low in lactose, with 13g per bar.

Carbs stay low at 9g by relying on a light wafer and a tiny dose of a zero‑calorie sweetener instead of oats or dried fruit.

Fat carries the texture at 15g, mostly from palm and palm‑kernel oils, which keep the creme snappy and the wafer crunchy, while cocoa, natural flavors, and small amounts of sugar and fructose build the chocolate‑berry profile.

Expect a confectioner’s ingredient list with seven modern additives (think sweeteners and emulsifiers) to land that bite.

IQBAR Wild Blueberry goes plant-first: pea protein sets the base, while almonds and coconut oil add staying power and a subtly rich bite. Real blueberries, including wild ones, drive both the color and flavor, and carbs stay low because most of them are soluble fibers refined from cassava and other vegetables.

You get 12g of protein, 180 calories, and 2g of sugar on a short label with only two true processing aids: a touch of stevia for sweetness and citric acid for brightness.

Vitamin E is also added (on top of what almonds provide) to hit 100% daily value, and there’s a sprinkle of lion’s mane for flair rather than nutritional heft.

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.

Peanut butter leads the way, and the label reads like a pantry: peanuts, vanilla, sea salt, and a little honey. For protein, Primal Kitchen uses eggs and egg whites—complete and dairy‑free—backed by peanuts, flaxseed, sunflower seeds, and almonds.

The build is fat‑forward and lower in carbs: 15 grams of fat, 10 grams of carbs, just 2 grams of sugar, with prebiotic tapioca fiber (a soluble fiber from cassava) and a hint of monk fruit for sweetness.

Additives stay minimal—two small helpers, sunflower lecithin to keep things blended and rosemary extract to protect the oils.

Dang’s Crazy Rich Chocolate reads like a dark-chocolate nut cluster in bar form: plant-based protein, low sugar, and a fat-forward build that actually tastes like chocolate because it uses real chocolate and cocoa butter.

The base comes from almonds, sunflower seeds, and coconut with a pinch of sea salt, while carbs are held down with chicory root fiber and a light touch of stevia. It’s vegan, gluten-free, and designed more for steady energy than a syrupy candy-bar experience.

The additive list is tiny—two small helpers: sunflower lecithin to keep the chocolate and fats smooth, and mixed tocopherols (vitamin E) to protect those delicate oils.

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 Chocolate Fudge Protein Bar is a deliberately light take on a chocolate fix: 90 calories, 10g protein, and a soft bite.

The protein comes from a blend—soy protein isolate does most of the lifting, with whey proteins and calcium caseinate (dairy) plus a small amount of collagen to keep the texture pliable.

Carbs lean on chicory root extract—a refined soluble fiber from chicory—and low‑calorie sweeteners rather than fruit or oats, while the fudge character is built from Dutch‑processed cocoa and cocoa powder. You’ll see 17 ingredients and four helper additives—emulsifiers and low‑calorie sweeteners—to keep it soft and sweet while holding calories down.

Big picture: it’s engineered for sweetness and softness without the calorie load.

Huel’s Dark Chocolate Raspberry wraps a dark cocoa coating around a tart raspberry layer, then keeps sugar low by leaning on maltitol (a sugar alcohol) and a pinch of stevia (a plant-based high-intensity sweetener) instead of added sugar.

The protein is fully plant-based—pea, rice, and wheat gluten—while carbs come mostly from soluble corn fiber (refined from corn starch), with a little glycerol (a plant-derived humectant) to keep the bite soft.

Fats are plant-derived too, mainly sunflower oil and cocoa butter with a touch of flax. At 180 calories and 1g sugar, it reads like a modern, engineered bar, and that is intentional: roughly 10 additives are used to deliver a soft chew and stable sweetness.

A built-in micronutrient blend boosts vitamins and minerals, but if you avoid gluten or react to sugar alcohols, note the wheat gluten and maltitol.
