Kerrygold Pure Irish Butter, Salted, 8 oz
Kerrygold's grass-fed Irish butter delivers 11g of fat per tablespoon with 0g carbs and 0g protein, making it a clean, keto-macro-friendly fat source that keto bloggers like Hip2Keto specifically recommend for bulletproof coffee and other high-fat keto staples.
Vital Farms Salted Butter, 8oz
Vital Farms' 90% grass-fed, pasture-raised salted butter delivers the same clean keto macros as Kerrygold (all fat, 0g carbs, 0g protein per serving) but with a richer, tangier cultured-cream flavor from US family farms where cows average 200 days a year on pasture; keto blogger Keto in the City specifically switched to it, saying standard butter now 'tastes like wax' by comparison.
Highest Certification (USDA Organic)Organic Valley Cultured Organic Pasture Butter, 8 oz
The only USDA Certified Organic pick of the three, Organic Valley's cultured pasture butter guarantees the cows' supplemental feed is non-GMO and organic on top of being grass/pasture-raised, and its cultured process adds naturally occurring CLA and omega-3s; reviewers at Ketozila and Buttered Side Up rate it a top choice specifically for shoppers who prioritize organic certification, while keeping the standard keto-friendly all-fat, zero-carb profile.
