Unflavored collagen peptides are generally keto-friendly: they’re mostly protein with ~0g net carbs and minimal additives. They can help you hit protein targets without adding carbs—just avoid flavored/sweetened versions that include sugar, maltodextrin, or significant fillers.
Most plain collagen powders are 0g net carbs per scoop and fit keto easily.
Best practice: treat collagen as a protein add-in (not a complete protein replacement).
