The 21 Best Peanut Butters for Keto Diets
1. Crazy Richard’s Crunchy Peanut Butter
With only 2g of net carbs per two-tablespoon serving, Crazy Richard’s ranks among the best keto peanut butter for its keto-friendly nutritional profile, simple ingredients and delicious taste. It really is just peanuts! This keto-friendly peanut butter brand prides itself on using ingredients you can recognize and pronounce, making it one of the healthiest peanut butter brands, even if you’re not keto.
Moreover, Crazy Richard’s is committed to sustainability and access, so unlike other specialty peanut butters, it won’t burn a hole in your wallet. It’s a keto peanut butter choice you can feel good about. As far as a best-of-the-best list of keto peanut butter brands goes, this one would definitely be included.
2. Americano Peanut Butter
Even with a slightly higher count of 3.33g of net carbs per 100g serving, Americano Peanut Butter is still one of the best keto peanut butters out there. It also contains no oils, food additives or sweeteners. Overall, this wholesome keto peanut butter brand is not only a keto-friendly pick but a healthier choice, too (not all of the best keto peanut butters are).
Americano Peanut Butter also provides another macronutrient keto dieters need: healthy fat. Without any added oils, you can be confident that the 15g per serving is a healthy, nut-based natural fat that fits the keto bill and is great for your heart.
3. Santa Cruz Organic Dark Roasted Peanut Butter
When you’re searching for the best keto peanut butter, it’s wise to think beyond macros. Sure, limiting carbs and including lots of healthy fats in your diet are essential, but it’s not worth sacrificing quality to meet those requirements. Natural ingredients will always be best, and that’s what makes Santa Cruz some of the best keto peanut butters in the business.
With 2g of net carbs per two-tablespoon serving, this brand is on par with others on that front. Plus, those carbs come from natural sources: peanuts and salt are the only ingredients on the label.
4. Wonderspread Peanut Butter
Enjoy this keto peanut butter in a little less moderation because it has an impressive 0g net carbs. That’s right, none! That alone would make Wonderspread one of the best keto peanut butters. But that’s not all: it’s also free of artificial colors, flavors and sweeteners.
That said, Wonderspread isn’t entirely as all-natural as some of its competitors. It contains peanuts, a modified oil called EPG, allulose and sunflower lecithin, as well as sea salt, stevia extract and monk fruit extract — all natural compounds, but most of them pretty unrecognizable.
Nutritionally, this one’s a winner: as well as no net carbs, it contains 9g of healthy fats and 6g of protein per serving. But if you’re looking for a natural brand with as few ingredients as possible, Wonderspread might not be the best keto peanut butter for you.
5. Maranatha Crunchy Peanut Butter
This organic, non-GMO peanut butter contains only 4g of net carbs per serving, plenty of healthy fats and no artificial colors or flavors. Actually, it contains nothing at all except peanuts and salt. Maranatha Crunchy Peanut Butter boasts the clean nutritional profile of all the best keto peanut butters.
It’s also high in healthy fats, with 17g per serving, and protein, at 8g per two tablespoons. With its straightforward ingredients and impressive nutrition stats, this is one of the best keto peanut butters worth buying two of — one for you and the other as a keto gift for your diet buddy.
6. Smucker’s Organic Chunky Peanut Butter
You might not have been expecting an ordinary supermarket brand like Smucker’s to be one of the best keto peanut butters, but it's here for a reason. Sure, you should consume it in moderation — 2g of net carbs per serving means you have to be mindful of portions. But it actually boasts an impressively natural ingredient list of nothing but peanuts and salt.
Naturally, it’s also free of additives, sweeteners and unhealthy fats. With 16g of fat and 8g of protein, it’s excellent for your macro counts across the board. And all of that in a reasonably priced, widely available jar of keto-friendly peanut butter. The best keto peanut butters don’t always come in a $12 bottle from the health foods store; you can find a suitable alternative even at your local supermarket.
7. Good Good Creamy Peanut Butter
With a growing demand for keto-friendly products, it’s no surprise that some peanut butter brands would make nothing else. That’s what Good Good does, aiming to manufacture and sell the best keto peanut butter on the market. Does it succeed? That’s ultimately up to you.
With 2g of net carbs, this product is comparable to most of the others we’ve looked at so far. It avoids palm oil and artificial sweeteners, but it still has a few more ingredients than some of the more whole-ingredient-focused peanut butters on this list. So, is Good Good Creamy Peanut Butter unequivocally the best keto peanut butter out there? Not quite. But it might be your favorite.
8. Giv Classic Peanut Butter
Though not made specifically with the keto diet in mind, Giv markets its healthy peanut butter product as keto-friendly. With 3g of net carbs, it’s not as keto-friendly as some of the other options here, but it won’t blow your carb budget for the day.
Giv, like Good Good, uses a handful of ingredients that might raise your eyebrow: monkfruit sweetener, MCT oil and sunflower lecithin. It’s not as simple as it could be, but you won’t find any added sugar or palm oil, ultimately making Giv a solid choice amongst the best keto peanut butters.
9. Laura Scudder’s Organic Nutty Peanut Butter
This organic peanut butter is another one to consume in moderation: its 4g of net carbs are okay, but that’s in a small serving. Anything beyond that is edging into the danger zone for keto dieters. That said, it’s one of the most wholesome and natural recipes out there if you can’t find a specialty brand that’s a little lower in carbs.
With nothing but peanuts and salt on the ingredient list, you’ll know exactly what you’re getting with Laura Scudder’s. Like most of the best keto peanut butters, it puts simplicity first.
10. Kroger Natural Creamy Peanut Butter
Like Smucker's, this is another classic supermarket peanut butter that may surprise you. You didn’t expect a perfectly ordinary product to cater to keto needs, did you? As you might be seeing by now, it turns out that some of the best keto peanut butters can be found on a supermarket shelf near you.
Although not the lowest on this list, it has 2g of net carbs per serving, much like some of the other products mentioned here. In moderation, it’s not too bad, and it’s so accessible that it’s hard to count it out. It also sticks to simple ingredients, something you won’t always find in a mass-market product like this or even in some of the best keto peanut butters.
11. Left Coast Performance Keto Peanut Butter
Left Coast Performance products are marketed at athletes, but this one is tailor-made for keto dieters of all types. With a simple ingredients list consisting only of peanuts, macadamia nuts, coconut oil and salt, it’s about as natural as you can get.
It doesn't have the lowest net carb count on this list, but at 2g per serving, you could say it's one of the best keto peanut butters from that point of view. A protein intake of 8g per serving is also a noteworthy nutritional stat, but be mindful of your portions as this brand has a slightly higher calorie count than most others.
12. Onnit Creamy Peanut Fatbutter
Onnit’s Creamy Peanut Fatbutter is an all-natural, organic peanut butter spread with additional ingredients like macadamia nuts and chia seeds for a filling, healthy boost. With 2g of net carbs, it matches many other brands mentioned above and below.
Worried about protein? With 7g per serving, it's an excellent choice for keto dieters. Overall, this is one of the best keto peanut butters to try if you want something with a little more dimension than the peanut-only products that dominate this list.
13. WiO SmartFoods Crunchy Peanut Butter
This popular brand isn’t just one of the best keto peanut butters — with only 1g of net carbs — it’s also nonfat, has no sugar added and is low in calories. While it takes some unusual ingredients to achieve that (fat and enzyme inhibitors, and a stabilizer), its healthy stats make this an appealing choice for keto dieters.
While it doesn’t have the simplest or most unprocessed ingredients, it’s one of the best keto peanut butters to try if you don’t want to worry about macros.
14. Natural Way Peanut Butter
With 2g of net carbs, olive oil instead of seed oil, and all-natural ingredients, Natural Way is an all-around winner that deserves a place among the best keto peanut butters on the market. The brand takes pride in using minimally processed ingredients for an unparalleled taste — no odd chemical aftertaste in sight.
Its simple yet delightful flavor also makes it one of the best picks for adding to a smoothie or slapping on some toast as a delicious keto lunch idea. Plus, with a competitive 8g per serving, its protein count will ensure your meals tick off all keto boxes.
15. Justin’s Classic Peanut Butter
Justin’s Classic Peanut Butter is as simple as it gets: just peanuts and palm oil. And while palm oil does have negative environmental impacts, Justin’s is committed to sustainable sourcing. It’s still not the healthiest oil, but Justin’s does it better than most brands.
Aside from that, there’s nothing to avoid in this widely available peanut butter. It’s organic and all-natural, with no added sugars or artificial flavors. With 5g of net carbs, this isn't the best keto peanut butter, but it can still be enjoyed in moderation.
16. 365 Everyday Value Organic Peanut Butter
Whole Foods’ flagship brand isn’t a bad choice, especially with only one ingredient: organic, dry-roasted peanuts. However, it’s not one of the best keto peanut butters, at 4g of net carbs per two-tablespoon serving. Still, it’s an accessible choice with a decent amount of protein (8g) that’ll definitely fit the bill, provided you eat it in moderation.
17. Once Again Organic Creamy Peanut Butter
This may not be the best keto peanut butter on this list, but once again (excuse the pun), it's a wise choice because it boasts a simple ingredient list. Its 5g of net carbs are a little steep for a keto snack, but a small serving wouldn't be too much of a deviation. With 8g of protein from peanuts alone, that's not a factor to worry about, though.
18. Teddie All-Natural Peanut Butter
Another member of the “nothing but peanuts and salt” club is Teddie All-Natural Peanut Butter. Its 4g of net carbs per serving makes it keto-friendly in moderation, and like all the best keto peanut butters on the market, you don’t have to worry about oils, sweeteners or GMO ingredients.
19. Adam’s 100% All-Natural Peanut Butter
Calling something 100% all-natural seems redundant (what else does “all” mean?), but Adam’s is in the business of making tasty peanut butter, nonetheless. And it does make one of the best keto peanut butters out there, so we’ll give them that.
Adam’s Peanut Butter only contains peanuts, salt and 4g of net carbs. We’ve been through this before: Anything higher than 2g per serving is probably something to watch your portions with. But you know that already, so go ahead and enjoy — just…responsibly.
20. PB2 Natural Creamy Peanut Butter
PB2 Natural Creamy Peanut Butter fits the nutrition and ingredient profiles of many of the products on this list. It’s primarily made of peanuts and salt (as well as allulose and palm oil), and at 4g of net carbs per serving, it’s about what you’d expect nutritionally. It may not have as impressive a carb count as some of the best keto peanut butters, but it does match their protein profiles, with 8g per serving.
21. Nuttzo Peanut Trail Mix Nut & Seed Butter
It’s easier to name a nut that isn’t in this peanut butter than to list the ones that are. Peanuts, cashews, almonds and Brazil nuts, along with hazelnuts, flax and sunflower seeds, round out its ingredient list, not forgetting salt.
So if you want the flavors and nutritional benefits of a half-dozen nuts and seeds in one product, this is the best keto peanut butter for you. From a keto nutritional profile, it’s not the best, but definitely not the worst, with 4g of net carbs.
What Is the Best Keto-Friendly Peanut Butter?
Though there are tons of options to choose from, Maranatha and Wonderspread would be up there as the best keto peanut butters, based on both macros and quality. Both are made with natural ingredients and are impressively low in carbs — two vital things to look for in the best keto peanut butter picks.
While keto might mean giving up a lot of the foods you love, peanut butter doesn’t have to be one of them. There are countless options on the market, and the best keto peanut butters are genuinely good-for-you snacks. So if you’re a peanut butter fiend, rest assured: you won’t have to give up your favorite food to reap the benefits of a keto lifestyle.
