Best Low Calorie Vegetarian Plant Protein Bars

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.

MOSH’s Banana Bread goes classic-comfort on flavor (real banana and cinnamon) and modern on nutrition with a dairy‑free plant‑protein trio.

It lands at 10g of protein and 170 calories, leaning on allulose—a low‑calorie sugar that’s gentler on blood glucose—and soluble tapioca fiber, a refined fiber from cassava, for sweetness and chew instead of syrups.

The 10 grams of fat come mostly from almonds, cocoa butter, and a little flax, which explains the soft, bakery‑like bite. Four small helpers—vegetable glycerin for moisture, sunflower lecithin for smooth mixing, and ascorbic and citric acids for freshness—keep the bar stable.

A modest “brain blend” adds vitamin D3 and B12; helpful, but not a health claim.

Promix Nutrition’s Coconut Protein Bar keeps things intentionally simple: whey-protein puffs supply the crisp, a marshmallow-style binder keeps it together, and real coconut flakes plus a touch of coconut oil deliver a toasty finish.

It’s a lighter, low-fat snack with 15g of protein and modest carbs—more bridge-the-gap fuel than a full meal.

Sweetness comes from a small amount of tapioca syrup (a cassava-derived syrup) rounded out by soluble fibers like inulin and tapioca-derived fiber, plus glycerin, a plant-based moisture keeper that tastes mildly sweet.

The net effect: dessert-like flavor without high-intensity sweeteners, in a gluten-free, soy-free bar.

Mosh’s Peanut Butter Crunch leans on dairy proteins—whey isolate, whey concentrate, and milk protein isolate—anchored by real peanuts for flavor and texture. It’s a trim 170-calorie bar with just 1 gram of sugar; sweetness comes from stevia and monk fruit rather than syrups.

Carbs are “engineered clean”: a refined, resistant tapioca fiber provides most of the bulk, with a little tapioca starch and plant-derived glycerin to keep the bar soft and cohesive. Fats land in the middle and are mostly peanut, with a touch of cocoa butter for creaminess.

Beyond that, you’ll spot a small Brain Blend and four functional add-ins—fiber to bulk and bind, glycerin to retain moisture, sunflower lecithin to emulsify, and stevia/monk fruit to sweeten—used for texture and stability rather than to goose the macros.

Maximuscle’s Chocolate Cookie and Milk builds its macros around milk proteins—casein and whey—with a small assist from soy and collagen, landing 16 grams of protein in a bar that eats like dessert.

Its label sugar stays low at 1. 7 grams because sweetness comes primarily from maltitol, a sugar alcohol, with a tiny backup of sucralose.

The unmistakably chocolate‑and‑milk character is driven by cocoa powder/cocoa butter and a soft, milky filling made with shea butter and whole milk powder, which is why the texture reads creamy rather than chewy.

Calories stay under 200, and the carbs are more engineered than oat‑or‑date based, which helps keep sweetness steady without a big sugar surge for many people.

IQBAR Matcha Chai leans into plant protein and spice: pea protein (plus crispies) sets the base while matcha and cinnamon bring gentle, chai-like warmth. The macro profile flips the usual script—very low digestible carbs built mostly from added plant fibers, higher fats from almonds and coconut oil, and a moderate 12g protein.

Sweetness comes from a tiny amount of stevia, a zero-calorie sweetener refined from the stevia leaf, instead of syrups. You also get an unusually strong hit of vitamin E thanks to almonds plus a touch added for stability.

The overall ingredient list stays tight and modern—nuts, pea protein, a prebiotic fiber blend, and spices—designed for steady energy rather than a sugar spike.

Raw Rev’s Chocolate Chip Cookie Dough goes all‑in on plant ingredients: a pea‑and‑rice protein blend tucked into a cashew base, warm vanilla, and real organic dark chocolate chips. At 180 calories with 11g of protein and 20g of carbs, it leans on a tapioca‑derived prebiotic fiber for structure and mild sweetness instead of straight sugar.

Fat runs a bit higher from nuts, seeds, and a touch of coconut oil, which is why the texture reads doughy rather than chalky. Sweetness stays modest—mostly monk fruit, with a little cane sugar in the chocolate chips—so the effect is dessert‑ish without a sugar rush.

It’s a concise ingredient list with about four functional helpers to keep things soft and the chocolate behaving, all in a dairy‑free, gluten‑free package aimed at steady energy.

good! snacks’ good!

KETO Choc Fudge reads like dessert but builds its base with plant protein. Pea protein crisps team up with brown rice protein, while almond butter, alkalized cocoa, dairy-free chocolate chips, and cocoa butter create that fudge-like chew.

Instead of dates or oats, it leans on soluble tapioca fiber and allulose—a low-calorie sugar—to bind and sweeten with a gentler blood-sugar impact. Fats come primarily from almonds and cocoa, not added seed oils, and the bar stays light at 170 calories with just 1g sugar.

Additives are kept modest: two small helpers, vegetable glycerin for softness and sunflower lecithin for texture.

Huel builds a cookie‑dough moment from a fully plant‑based protein blend—wheat gluten for structure and chew, with pea, soy, and rice proteins rounding out the amino acids—under a chocolatey coat with real chips.

At 178 calories with 13g protein and just 2g sugar, it leans on modern food tech for texture and sweetness: soluble corn fiber (a refined fiber that resists digestion), maltitol (a sugar alcohol that tastes like sugar but contributes fewer calories), and a touch of glycerol to keep it soft—no high‑intensity artificial sweeteners.

Fats come mainly from refined sunflower oil and cocoa butter, with a small whole‑food nudge from ground flaxseed, so the fat profile skews mostly unsaturated. The quiet flex is the micronutrient fortification—vitamins D3, K2, C, E, a B‑complex, and minerals—showing up at meaningful daily values.
