What's in the Bison with Beef + Sea Salt + Pepper EPIC Provisions bar?

EPIC Provisions’ Bison with Beef + Sea Salt + Pepper keeps things strikingly simple: meat-based protein, pantry spices, and a macro profile you almost never see in bars. It’s 110 calories with 10g protein, 7g fat, 2g carbs, and 0g sugar—savory by design, not sweet.

Of the eight total ingredients, two are small curing helpers to keep it safe on the go: lactic acid (a fermentation-derived acid that lowers pH) and cultured celery powder (a plant source of nitrite used in meat curing).

The rest is what you’d expect from a peppered jerky—bison, beef, sea salt, black pepper, onion, and garlic—without syrups, sugar alcohols, or high-intensity sweeteners.

What are people saying?

Main praise: Fans love the no-nonsense recipe—just meat and spices, no powders or sweeteners—and the jerky-like chew that delivers steady energy without a sugar rush.

Main criticism: Taste is polarizing: the tangy, chewy cured-meat profile and relatively high sodium won’t suit everyone, and at 10g protein the small bar can feel skimpy for the price.

Bottom Line

Savory snackers, keto/paleo eaters, and hikers who want a portable, zero-sugar protein top-up; pair with fruit or nuts if you need more energy.

What's in the Salted Caramel Chip IQBAR bar?

Plant-based through and through, IQBAR’s Salted Caramel Chip leans on pea protein and nuts for substance, then finishes with a restrained salted-caramel-and-chocolate vibe.

A prebiotic blend of soluble tapioca and vegetable fibers keeps total carbs low at 9 grams, while almonds, macadamias, and a bit of coconut oil supply satisfying fats for 170 calories.

Sweetness comes via stevia—no sugar alcohols—with just 1 gram of sugar. The label is tidy: 16 ingredients with just one additive by our count, plus a full day’s worth of vitamin E and useful iron and magnesium.

There’s also a modest sprinkle of lion’s mane, a functional flourish rather than the headline act.

What are people saying?

Main praise: Reviewers love that it’s a vegan, low-carb bar with no sugar alcohols that still tastes satisfying—soft with a little crunch and a gentle sweetness.

Main criticism: The divide is taste and texture: some notice stevia and pea-protein notes, want more than 12g protein, or find the added fibers and lion’s mane not to their liking.

Bottom Line

Low-carb snackers and plant-based eaters who want a tidy, not-too-sweet bar without sugar alcohols—better as a small breakfast anchor or afternoon tide-me-over than a heavy post-workout meal.

What's in the Peanut Butter Dark Chocolate Atlas bar?

Atlas leans into peanut butter and dark chocolate but rewrites the sugar script. The protein is fully plant‑based—a rice‑and‑almond base with crunchy pea‑protein crisps—boosted by peanut butter and peanut flour.

The chew comes from soluble tapioca fiber (a refined binder from cassava) and a little plant‑derived glycerin to keep things soft, while sweetness relies on allulose, a low‑calorie sugar that behaves like the real thing, plus concentrated monk fruit extract.

Fats are mostly peanut‑driven, with small amounts of cocoa butter and coconut oil for structure. Net result: a vegan, gluten‑free, keto‑friendly bar with 15 grams of protein, 180 calories, only 0.

5 grams of sugar, and a quietly impressive 38% Daily Value of iron from the cocoa components.

What are people saying?

Main praise: Fans praise the real peanut‑butter flavor with restrained sweetness, a clean ingredient list that keeps energy steadier, and a surprisingly satisfying texture for a 180‑calorie snack.

Main criticism: The knocks: batch‑to‑batch texture swings (oily shell or sandy center), occasional monk‑fruit/earthy aftertaste, a premium price, and an ashwagandha add‑in some don’t want.

Bottom Line

Choose it if you want a low‑sugar, dairy‑free bar that actually tastes like peanuts and cocoa, prefer gentle sweetness over candy‑bar sweetness, and would appreciate an iron bonus in a tidy 180‑calorie snack.

What's in the Peanut Butter Primal Kitchen bar?

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.

What are people saying?

Main praise: Clean, pantry‑style ingredients with gentle sweetness (honey plus monk fruit), slow‑steady energy, and whey‑free complete protein from egg whites.

Main criticism: Polarizing taste and texture with only 9 grams of protein—some find it bland or chalky, and the refined tapioca fiber can be noticeable for very sensitive stomachs.

Bottom Line

Choose it if you want a low‑sugar, keto‑leaning, dairy‑free snack that tastes like peanut butter first and a protein bar second—steady afternoon fuel rather than a dessert.
