The Nulla Gourmet protein bar from CleanForm Nutrition takes a different route from the keto bars I usually see with BHB on the label. It is a 20 g protein bar sweetened partly with honey, and it adds 1 g of goBHB® to the carbs on purpose. I wanted to see how that holds up when you read the actual label instead of the marketing.
Full disclosure before anything else: goBHB Labs supplies the goBHB in this bar, so we have a stake in it selling. That is exactly why I am going to stick to what the nutrition panel says and what the BHB research does and does not support at a 1 g dose.
What’s in the Nulla Gourmet Protein Bar
CleanForm sells Nulla Gourmet with goBHB in three flavors: Chocolate Chip Crisp, Peanut Butter Cup and Fudge Brownie, listed at $39.99 on its site. CleanForm’s product page says each bar has 20 g of protein, zero seed oils, zero gluten and 1 gram of goBHB. Here is the Chocolate Chip Crisp nutrition panel for one 68 g bar.
| Per bar (68 g) | Amount |
| Calories | 260 |
| Protein | 20 g |
| Total fat (saturated) | 11 g (2 g) |
| Total carbohydrate | 28 g |
| Fiber | 3 g |
| Total sugars (added) | 15 g (12 g) |
| Sodium | 15 mg |
| goBHB (per CleanForm) | 1 g |
The ingredient list starts with almond butter, honey, allulose, milk protein isolate and whey protein isolate, followed by dark chocolate, a whey crisp, vegetable glycerin and monk fruit. The goBHB appears last, as sodium beta-hydroxybutyrate. It contains milk, almond and soy, and it is made in a facility that also handles peanuts, wheat, tree nuts and egg.
How 1 g of goBHB Compares to the Research
This is the part I care about most, because the dose decides whether BHB is doing anything. Among the human trials we cite, the lowest daily amount is 1.5 g of D-BHB. In a 2025 Japanese trial, 108 adults with high visceral fat took 1.5 g or 2.9 g of D-BHB two hours before dinner for 12 weeks, and visceral fat area dropped 10.6 cm² and 10.9 cm² more than placebo. Several authors work for Osaka Gas, which makes that D-BHB. In the KETAD trial, people on a calorie deficit took 10 g a day of BHB salts and lost 3.05 kg versus 1.51 kg on placebo over 8 weeks, a trend rather than a significant difference (p = 0.09), in a study Ketone Labs funded.
How much BHB: one Nulla bar vs. the research
Grams of BHB per bar, per single test dose, or per day in published human studies.
Sources: CleanForm Nutrition product page and the studies linked at the end of this article. Forms differ (D-BHB, racemic salts, sodium BHB), so grams are not exactly equivalent.
So one bar sits below every dose in the trials we cite. Two bars get you to 2 g, the single dose Nova Southeastern researchers gave fasted (not with 56 g of carbs) in a reaction time study where the main analysis was not significant; the authors thank Ketone Labs for supporting that project. I would not buy this bar expecting the results from those trials. If you want a studied dose of BHB, take a dedicated goBHB powder or drink and think of the bar as food.
Honey Plus BHB: The “Dual Fuel” Idea
CleanForm’s product page calls this dual fuel: carbohydrate from honey for quick energy, plus BHB as a second fuel. It is the same carbs-plus-ketones idea we covered in our dual fuel training posts. In the Oxford work by Stubbs and colleagues, taking a ketone drink with a meal still raised blood BHB, but the peak was 33% lower than fasted (2.2 mM vs. 3.3 mM). That study used a ketone ester supplied by TΔS, which employed one of the authors, and nobody has measured blood BHB after eating this bar.
The honey also changes who the bar is for. With 28 g of carbs and 12 g of added sugar, this is not a keto bar. For someone eating carbs who wants a bar without seed oils before training or on a long travel day, that is fine. For strict keto, it will not fit most days.
Who the Nulla Gourmet Protein Bar Makes Sense For
I like this bar for people who want 20 g of protein from milk and whey isolates without seed oils or gluten, for anyone who wants a snack with some carbohydrate 30 to 60 minutes before an afternoon workout, and for people already using goBHB who want a food that fits the same routine. In my opinion the ingredient list is short and easy to read for a protein bar.
It is a weaker choice if you are on a strict ketogenic diet, avoiding added sugar, allergic to milk, soy or tree nuts, or looking for a meaningful dose of BHB from one product. For our side-by-side of every goBHB product and its dose, see goBHB Products You Can Buy Right Now: The 2026 Guide.
Where the Evidence Stands
There is no published study on this bar, and I am not aware of any planned one. The protein, fat and carb numbers come straight from the label, which is the part you can rely on. The BHB evidence comes from trials of 1.5 to 10 g a day, nearly all funded or run by companies that make BHB, and none of them tested 1 g. If you want to know whether BHB curbs hunger, our review of the appetite research is in Ketones and Appetite: Do BHB Supplements Curb Hunger?
FAQ
How much goBHB is in a Nulla Gourmet bar?
CleanForm lists 1 gram of goBHB per bar, added as sodium beta-hydroxybutyrate. That is below the 1.5 g daily dose of D-BHB used in the lowest-dose human trials.
Is the Nulla Gourmet protein bar keto?
Not really. The Chocolate Chip Crisp bar has 28 g of total carbs and 12 g of added sugar, from honey and the dark chocolate. It is built for people who eat carbs and want BHB alongside them.
Does Nulla Gourmet contain seed oils or gluten?
The brand says it has zero seed oils and zero gluten. It does contain milk, almond and soy, and it is made in a shared facility with peanuts, wheat, tree nuts and egg.
Will one bar put me in ketosis?
Unlikely. One gram of BHB with 28 g of carbs is a small amount, and food blunts the rise in blood BHB. Use a dedicated BHB product if you want a measurable ketone level.
The Bottom Line
The Nulla Gourmet protein bar is a 260 calorie bar with 20 g of protein, no seed oils and no gluten, with 1 g of goBHB as a bonus. Buy it as a better protein bar, not as your BHB dose. If you want a dose closer to what the trials tested, use a dedicated goBHB product alongside it, and talk to your doctor first if you are pregnant or take medication. None of these products are meant to treat or prevent any disease.
