Primal Kitchen
Peanut Butter
TL:DR
In 2 Sentences
Egg‑white protein in a peanut‑butter bar, with real‑food ingredients and just 2 grams of sugar from honey plus monk fruit—dairy‑free and free of sugar alcohols.
When to choose Primal Kitchen Peanut Butter
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.
What's in the Primal Kitchen bar?
Peanut butter first, and it shows: peanuts lead the ingredient list, with vanilla, sea salt, and a little honey rounding out those classic peanut‑butter notes. For protein, Primal Kitchen leans on eggs and egg whites, giving you a high‑quality complete protein alongside plant proteins from peanuts, flaxseed, sunflower seeds, and almonds.
It’s a fat‑forward, lower‑carb build—15 grams of fat and just 10 grams of carbs—thanks to nuts, seeds, and prebiotic tapioca fiber (a refined fiber from cassava) plus a whisper of monk fruit for sweetness.
At 9 grams of protein it’s lighter than the gym‑bro bars, but designed for steady, longer‑burn energy rather than a sugar rush. If you’re after a keto‑leaning peanut butter bar with real‑food ingredients and a softer sweet profile, this one fits the brief.

Protein
915LOWEggs and egg whites do the heavy lifting for protein here, with help from peanuts, flaxseed, sunflower seeds, and almonds. Egg‑white protein is a complete, highly digestible source, but at 9 grams total this sits on the lighter end compared with many protein bars. The mix gives you high‑quality egg protein plus a supporting cast of plant proteins—more about balance than a mega dose.
Fat
159HIGHAt 15 grams, fat is front and center, largely from peanuts, sunflower seeds, almonds, and added peanut and coconut oils. The nuts and seeds supply mostly unsaturated fats and some natural vitamin E, while coconut oil nudges the profile toward saturated fat. It’s a rich, lasting fuel—great for satiety—though anyone minimizing saturated fat may want to keep portions mindful.
Carbs
1020LOWMost of the 10 grams of carbs come from prebiotic tapioca fiber, a refined soluble fiber made from cassava, with a small contribution from honey. That means sweetness and texture without a big blood‑sugar surge, since fiber slows absorption and the honey is modest. Expect steadier, fat‑and‑fiber‑led energy rather than a quick carb spike.
Sugar
24MIDJust 2 grams of sugar, mainly from a touch of honey; the rest of the sweetness comes from monk fruit, a concentrated extract from a small Asian gourd that adds sweetness without sugar. Keeping sugar modest avoids a crash, and the fiber base further tempers blood‑sugar swings. If you prefer to avoid high‑intensity sweeteners, know that monk fruit is used here in tiny amounts for balance.
Calories
200210MIDWith 200 calories, this bar lands mid‑pack, but most of that energy comes from fat (roughly two‑thirds), with moderate protein and relatively low digestible carbs. That macro split favors slow, sustained fuel over quick sugar. If your goal is maximum protein per calorie, this skews more toward satisfying snack than pure protein delivery.
Vitamins & Minerals
There aren’t any stand‑out vitamins over 10% of daily value—this bar isn’t fortified. The nuts and seeds naturally contribute small amounts of vitamin E, magnesium, and potassium, and the label shows modest iron and potassium. Think of it as a whole‑food‑leaning bar with micronutrient sprinkles, not a multivitamin.
Additives
Beyond the whole ingredients, a few helpers do specific jobs: sunflower lecithin keeps fats and water blended, rosemary extract protects the oils from going rancid, and vanilla plus monk fruit fine‑tune flavor and sweetness. Prebiotic tapioca fiber is a manufactured soluble fiber from cassava that adds bulk with minimal sugar. Overall the additive list is short and purposeful rather than heavy‑handed.

What are people saying?
Sources
Range
“Marigold and Primal Kitchen are two good brands that use monkfruit - the latter uses a teeny tiny bit of honey with monkfruit but it's a small enough amount that it's still like 4g net carbs a bar.”
“Mark Sisson's brand. They're awesome. Also see their mayo, marinades, and protein powders/bars. I usually buy their avocado oil.”
Main Praise
The biggest win here is the ingredient philosophy: peanuts, eggs, seeds, and a short list of helpers rather than a chemistry set. The sweetness is modest and comes from a tiny bit of honey balanced with monk fruit, so you avoid the sugar‑alcohol roller coaster that bothers some people.
At 200 calories with 15 grams of fat and 10 grams of carbs (mostly fiber), it delivers slow, steady energy instead of a quick spike. If you can’t do whey, the egg‑white protein is a complete, highly digestible alternative that plays nicely with a dairy‑free routine.
And while taste is subjective, peanut butter is the flavor fans most frequently point to as the safest, most straightforward pick—clean, nutty, not cloying. Editorial roundups often highlight Primal Kitchen bars for being low in sugar and whey‑free, which fits the ethos of this flavor, too.
Main Criticism
Taste and texture draw the most heat.
Several Amazon reviewers complained of odd, soapy or floral notes in certain flavors, and a few called the texture chalky or dry; even one positive reviewer admitted the bars improved when paired with whipped cream.
The protein is on the lighter side at 9 grams, so if you’re hunting for a 20‑gram post‑lift bar, this won’t scratch that itch. The sweetness is intentionally restrained, which some love—and others interpret as “bland.
” Finally, like many fiber‑forward bars, the refined tapioca fiber can feel noticeable for very sensitive stomachs, though there’s no avalanche of sugar alcohols here.
The Middle Ground
So which is it—clean fuel or polarizing snack? Both, depending on what you want from a bar.
If your non‑negotiables are dairy‑free protein, a short ingredient list, and very low sugar, this checks boxes without leaning on sugar alcohols. If you expect dessert‑level sweetness or a marshmallow‑chewy bite, you’ll likely side with reviewers like Michael gonz, who called a flavor “floral scented candle.
” Worth noting: the harshest taste complaints cluster around spiced flavors like Almond Spice (Ashley Cooper’s “putrid” experience reads like a spice mismatch), while Peanut Butter has steadier feedback—Nikki Jimenez even said her partner loves the PB one.
On macros, Reddit keto folks praise the low net carbs, but gym‑goers chasing high protein per calorie will find 9 grams underwhelming. And if you avoid refined seed or legume oils entirely, remember there’s peanut oil and sunflower‑derived lecithin in the mix—minor components, but worth a glance for purists.
What's the bottom line?
Primal Kitchen’s Peanut Butter bar is a smart pick for peanut‑butter loyalists who want low sugar, slow‑burn energy, and dairy‑free protein without the sugar‑alcohol side effects. It’s fat‑forward and calm on sweetness, more real‑food snack than protein megadose. If your goal is steady fuel between meals or a simple, peanut‑centric bar you can toss in a bag, this fits beautifully.
If, however, you equate “protein bar” with 20 grams of protein and a candy‑bar experience, you’ll feel shortchanged. Start with the Peanut Butter flavor (the least polarizing), buy a single to test your tastebuds, and consider it a tidy PB packet with benefits—eggs for complete protein, fiber for fullness, and just 2 grams of sugar.
Quick listicle take: A low‑sugar, dairy‑free peanut‑butter bar that favors steady energy over dessert vibes; 9 grams of egg‑white protein, 15 grams of fat, and an ingredient list that reads like a pantry. Best for keto‑leaning snackers and PB purists; not for 20‑gram‑protein chasers or sweet‑tooth diehards.
