Justin’s Classic Almond Butter is my pick for most keto shoppers. Its brand panel gives you 2g net carbs, 19g fat and 0g added sugars per serving, with just dry roasted almonds and palm oil in the ingredients. If you want to skip added oil, Crazy Richard’s peanut butter and Wilderness Poets macadamia butter keep their ingredient lists to the nuts themselves.
These are nutrition and ingredient comparisons as of October 24, 2026, with no taste ratings. Net carbs here means total carbohydrate minus dietary fiber; none of these picks requires an erythritol, allulose or xylitol deduction. Each number uses the printed serving. Labels change, so check the jar you buy.
Compare the printed servings
| Product | Printed serving | Total carbs | Fiber | Net carbs | Fat | Protein |
|---|---|---|---|---|---|---|
| Justin’s Classic Almond Butter | 2 tbsp (32g) | 5g | 3g | 2g | 19g | 6g |
| Barney Butter Bare Smooth | 2 Tbsp (32g) | 6g | 4g | 2g | 18g | 7g |
| MaraNatha No Sugar or Salt Added Creamy Almond | 2 Tbsp (32g) | 6g | 3g | 3g | 17g | 7g |
| Crazy Richard’s 100% Peanuts Creamy | 2 Tbsp (32g) | 7g | 3g | 4g | 16g | 8g |
| SunButter No Sugar Added | 2 TBSP (32g) | 5g | 3g | 2g | 18g | 7g |
| Wilderness Poets Raw Macadamia | 2 Tbsp (28g) | 4g | 2g | 2g | 20g | 4g |
Use the gram weight when measuring a serving. Tablespoons are handy in the kitchen, but a heaped spoon can make a low-carb jar use more of your daily budget than you planned.
Justin’s Classic: best overall
The Classic almond butter brand panel lists 5g total carbohydrate, 3g fiber and 6g protein per serving. Subtracting fiber gives 2g net carbs. It also prints 1g total sugars and 0g added sugars.
The ingredient list is dry roasted almonds and palm oil. I like the short list and low net-carb count. Palm oil is the main reason I’d choose something else: the peanut and macadamia picks keep their ingredients to the nuts themselves.
Barney Butter Bare Smooth: most fiber per serving
Barney Bare uses blanched roasted almonds and palm fruit oil, with no added sugar or salt in the ingredients. The Amazon retailer label lists 6g total carbohydrate, 4g fiber, 18g fat and 7g protein per serving; check the jar because retailer label versions differ.
The subtraction gives 2g net carbs, and its fiber is the highest in this group. It’s the almond option I’d look at first if I wanted no added salt. It still contains palm fruit oil, so Bare doesn’t mean almonds alone.
MaraNatha: salt-free almond option
MaraNatha No Sugar or Salt Added contains dry roasted almonds and palm oil. Its brand label lists 6g carbohydrate, 3g fiber, 17g fat and 7g protein, giving 3g net carbs per serving. Sodium is 0mg.
It has 2g total sugars, but the panel prints 0g added sugars and the ingredients contain no sweetener. It uses more of a net-carb budget than the other almond picks. Choose it for the lack of added salt, rather than expecting the lowest carbs in the almond group.
Crazy Richard’s: best peanut butter
The brand’s creamy peanut butter page lists peanuts as the only ingredient, with 7g carbohydrate, 16g fat and 8g protein per serving. A USDA branded food record mirrored by MyFoodData lists 3g fiber and 2g total sugars; check the jar’s fiber before using the 4g net-carb calculation.
This is the pick for a peanut-only ingredient list and the most protein among these printed servings. The trade-off is the highest net-carb figure in the table. Oil separates, so stirring is part of the deal. If you want peanuts without sweeteners or stabilizing oil, that’s a reasonable bit of spoon work.
SunButter No Sugar Added: best seed butter
SunButter is the nut-free option, made with roasted sunflower seeds and salt. The Giant retailer label lists 5g carbohydrate, 3g fiber, 18g fat and 7g protein per serving, giving 2g net carbs; check the jar because label versions differ.
You get a short ingredient list without palm oil or sweeteners. Added salt is the trade-off if you’re looking for a completely unsalted spread. For allergy shopping, make the package’s allergen information part of your decision.
Wilderness Poets: best macadamia butter
The brand lists raw macadamia nuts, with no added oil, sugar or salt. A USDA branded food record mirrored by MyFoodData lists 2 Tbsp (28g): 4g carbohydrate, 2g fiber, 20g fat and 4g protein, giving 2g net carbs.
Its 28g serving is smaller than the other jars’ 32g servings, so the carb figures aren’t an equal-weight comparison. I’d choose this for macadamia nuts without added ingredients. It has less protein per serving than the other picks, so Crazy Richard’s makes more sense if protein is your priority.
How to choose keto nut butter
Read total carbs and fiber together
The American Diabetes Association explains that net carbs has no legal definition. It’s a useful comparison convention here, but the total-carbohydrate figure should stay visible. If your eating plan counts total carbs, use that column directly.
Measure the printed serving when checking how a butter fits your budget. A spoon is a utensil, not a nutrition label. A jar with low net carbs per serving still needs a serving size.
Separate total sugar from added sugar
The FDA explains that Added Sugars are included within Total Sugars. Don’t add those lines together or reject an unsweetened jar simply because it contains naturally occurring sugar. Justin’s and MaraNatha demonstrate the distinction on their panels.
Scan the ingredients for cane sugar, honey, maple and syrups. Then decide whether you want added stabilizing oil or salt. Barney, Justin’s and MaraNatha include palm oil; the peanut, sunflower and macadamia picks don’t. Those differences are more useful than a vague natural badge on the front.
What to avoid or leave out
Skip Barney Smooth without Bare, MaraNatha regular No Stir Creamy, SunButter Original and Justin’s sweetened flavors for this no-added-sugar shortlist. Similar branding doesn’t give them the selected jars’ numbers.
Perfect Keto’s macadamia coconut butter was discontinued, so leftover retailer listings don’t make it a dependable regular buy. Legendary’s flavored spreads use sweeteners, while this list favors unsweetened jars. Artisana’s macadamia-cashew blend shows sold out on its brand shop. For any alternative, check the full ingredient list and the carbs on the jar before swapping it into your usual serving.
