Perfect Keto
Lemon Poppyseed
TL:DR
In 2 Sentences
A rare lemon‑poppyseed bar anchored by grass‑fed collagen and a fat‑first, no–sugar‑alcohol formula—more mini‑meal than protein bomb.
When to choose Perfect Keto Lemon Poppyseed
Best for keto eaters who want bright flavor and long‑lasting satiety between meals and who do fine with stevia. Skip if you need vegetarian or a high protein‑to‑calorie ratio.
What's in the Perfect Keto bar?
Perfect Keto’s Lemon Poppyseed Protein Bar is a fat‑forward, low‑carb mini‑meal with a bright citrus twist. The lemon character comes from organic lemon oil and natural flavors, while poppy seeds add that classic speckled crunch.
Protein is supplied by grass‑fed bovine collagen (not dairy), coming in at a modest 11 grams—enough for a snack, but not a heavy hitter.
Most of the energy here rides in on fats—almond butter, cacao butter, and a touch of MCT oil—putting this bar near the top of the pack for fat and toward the bottom for carbs.
Sweetness is dialed in with stevia rather than sugar, and the bar leans on soluble tapioca fiber (a refined, digestion‑resistant fiber from cassava) and acacia fiber to keep the carbs steady.
Big picture: lemony, crunchy, and designed for keto priorities—high fat, low sugar, and fiber‑leaning carbs.

Protein
1115LOWThe 11 grams of protein come from grass‑fed bovine collagen—an animal‑derived protein that mixes cleanly and keeps carbs near zero. Collagen is rich in glycine and proline but lacks some essential amino acids, so it’s not a complete protein; think of this as a snack‑level protein boost rather than a stand‑alone muscle bar. If you’re chasing recovery, pair it with a complete protein elsewhere in your day.
Fat
189HIGHMost of the fat is from almond butter (mostly heart‑friendly monounsaturated fat), cacao butter (a saturated fat rich in stearic acid, which tends to be gentler on LDL than many saturated fats), and a little MCT oil for quick‑burning energy. The result is sustained fullness with a touch of fast fuel—very keto‑friendly. If you’re watching cholesterol, remember cocoa butter is still a saturated fat; balance with unsaturated fats in the rest of your day.
Carbs
1020LOWCarbs here are low and mostly tied up in soluble fibers: a cassava‑derived resistant dextrin (soluble tapioca fiber) and acacia fiber carried with the MCT powder, plus small amounts from nuts and seeds. These fibers are highly processed but generally help keep blood sugar steadier than sugars or refined starches. Sensitive stomach? Rapid increases in fermentable fiber can cause gas or bloating for some—pace yourself.
Sugar
14LOWOnly 1 gram of sugar shows up naturally from ingredients like nuts; the sweetness comes from stevia, a high‑intensity, zero‑calorie sweetener purified from stevia leaves. That keeps sugars low without sugar alcohols, though stevia is a highly refined ingredient and some people notice a slight aftertaste. If you prefer sweetness from fruit sugars, this bar goes a different route.
Calories
240210HIGHAt 240 calories, this is more mini‑meal than dainty snack, and most of those calories come from fat (9 calories per gram adds up fast). Protein and carbs play smaller roles here by design, supporting a keto‑style macro split. It’s a good fit when you want staying power without a carb spike.
Vitamins & Minerals
There aren’t standout vitamins or minerals over 10% Daily Value. You’ll get small amounts of minerals like calcium and iron (almonds and poppy seeds help there), and likely a touch of vitamin E from almonds, but this bar isn’t built to be a multivitamin—its strengths are macros and steady energy.
Additives
A short list of modern helpers keeps texture and sweetness on point: sunflower lecithin (an emulsifier), stevia (a high‑intensity sweetener), and natural flavors alongside lemon oil. The fibers—soluble tapioca fiber and acacia—are refined, functional ingredients that add bulk and help blunt blood sugar. Overall, it’s a relatively streamlined formula with a few well‑established, but processed, additives.

What are people saying?

Range
“I've really enjoyed the bars by Perfect Keto. I prefer them to any protein bars I've found in the grocery store. So far, the original almond butter brownie is my favorite, though I haven't yet tried the new chocolate chip cookie dough.”
“Perfect Keto is the best in my opinion. I have tried all the ones recommended and any perfect Leto bar beats these on quality, ingredients but maybe most importantly, taste and mouth feel”
“Best to stick with clean bars like Perfect Keto or RXBARs if you don’t mind the higher protein.”
Main Praise
Two big wins keep coming up.
First, macro integrity: very low sugar without sugar alcohols, low carbs largely from digestion‑resistant fibers (refined from cassava and acacia), and fats from almond butter and cocoa butter for staying power—exactly what many keto folks are after.
Second, the taste and mouthfeel exceed expectations for a keto bar; multiple Redditors call Perfect Keto their favorite for flavor and texture, and both Garage Gym Reviews and BarBend staffers praised the creamy, melt‑in‑your‑mouth base across flavors.
Lemon poppyseed adds a bright, bakery‑adjacent twist you almost never see in the keto aisle, and the poppy seeds give a little crunch so it doesn’t feel gummy. The ingredient list is relatively short, the collagen is grass‑fed, and the sweetness avoids sugar alcohols that can bother some stomachs.
For many, it reads as a clean, portable keto mini‑meal that actually satisfies.
Main Criticism
Price is the loudest knock—several buyers and Redditors call it too expensive for everyday use. The stevia sweetness can polarize; some notice a lingering aftertaste or find it simply too sweet.
Texture is another mixed bag: a few describe it as chalky or sandy, and the bar can soften notably in heat. From a macro lens, 11g of collagen protein at 240 calories isn’t a great protein‑per‑calorie play, and collagen isn’t a complete protein, so post‑workout recovery seekers may want more.
There’s also ongoing chatter in keto forums about products labeled “soluble tapioca fiber” and whether certain versions behave more like digestible carbs for some people—responses seem to vary, so personal testing matters.
Finally, a handful of users have reported a “chemical” taste in certain batches; while that’s not universal, it’s worth trying a single bar before committing.
The Middle Ground
So which is it—creamy lemon bliss or never‑again? The truth likely depends on two personal variables: how you feel about stevia and what you want a bar to do.
If you need a high protein‑to‑calorie ratio or a complete protein, this isn’t your hero; it’s a fat‑forward snack that happens to carry 11g of collagen. But if your priority is low sugar, no sugar alcohols, and steady energy, the formula makes a lot of sense.
Texture gripes often track with temperature (cold bars skew firmer and chalkier; room temp can taste creamier), and stevia is famously divisive—no macro can out‑argue your taste buds.
As for the Redditor who called lemon poppyseed “absolutely disgusting,” another Redditor in the same ecosystem swears Perfect Keto has the best taste and mouthfeel of any keto bar they’ve tried.
Both can be true; your palate decides. If you’re curious, start with a single bar, and if you want it to pull weight post‑workout, pair it with a complete protein like eggs or a scoop of whey.
What's the bottom line?
Perfect Keto’s Lemon Poppyseed Bar is a keto‑first snack that trades high protein for high satiety: 18g fat, 11g collagen protein, 10g carbs, and just 1g sugar in a bright, lemony package. It shines for people who want low sugar without sugar alcohols, simple‑ish ingredients, and a flavor that feels more bakery case than candy aisle. Buy it if you love lemon, do fine with stevia, and want a portable mini‑meal that won’t spike carbs.
Skip it if you’re vegetarian, stevia‑averse, or chasing maximum protein per calorie. For gym days, treat it as the satisfying fat‑and‑fiber part of the plan and add a complete protein. And given the polarized taste reviews, try one bar before you spring for a whole box—your palate will cast the deciding vote.
