Crazy Richard's Creamy Peanut Butter, 100% Natural, Non-GMO, Gluten-Free (16 oz Jars, Pack of 6)
Crazy Richard's is a single-ingredient (just dry-roasted peanuts) peanut butter with no added sugar, oils, or preservatives, which Keto Chow's brand roundup names a top keto pick specifically because it avoids the sweeteners and palm oil fillers that inflate net carbs in mainstream brands.
Budget PickAdams Natural Creamy Peanut Butter, 16 oz Jar
Adams is a two-ingredient peanut butter (99% fresh-roasted peanuts plus a dash of salt) that costs noticeably less per ounce than boutique keto brands like Crazy Richard's while still avoiding added sugar, palm oil, and hydrogenated fats; it's a long-running grocery-aisle staple (now under J.M. Smucker) with consistently positive reviews for its simple, no-frills ingredient list, making it the pragmatic choice for shoppers who want the same keto-safe macros without the premium price.
