How much protein does peanut butter have per tablespoon?

1 tablespoon of peanut butter contains 3-4g of plant-based protein along with healthy fats and fiber. While not as protein-dense as animal sources, it's a convenient protein addition to meals and snacks. Peanut butter also provides essential fatty acids, vitamin E, niacin, and magnesium. It's particularly useful for adding protein to smoothies, oatmeal, or as a quick snack when combined with fruits.
