How Much Protein is in 2 Spoons of Peanut Butter? The Exact Answer
For most standard, commercially available peanut butter brands, a two-tablespoon (or 32-gram) serving provides between 7 and 8 grams of protein. The precise number can fluctuate based on the manufacturer and the type of peanut butter, for instance, natural versus conventional varieties. For those measuring in teaspoons, one tablespoon (half a serving) would contain approximately 3.5 to 4 grams of protein. This protein contributes to muscle repair and growth, making it a popular choice for athletes and fitness enthusiasts.
Breakdown of the Standard 2-Tablespoon Serving
A two-tablespoon serving of peanut butter is also packed with other nutrients besides just protein. According to the USDA and various nutrition databases, this serving size offers a substantial nutritional profile.
Typical Nutritional Profile (per 2 tbsp/32g):
- Protein: 7–8g
- Fat: 16g (mostly heart-healthy mono- and polyunsaturated fats)
- Carbohydrates: 7g
- Fiber: 2–3g
- Sugar: 1–3g (depending on the brand and additives)
- Calories: 190–200 calories
Factors That Influence Protein Content
The protein content can vary slightly depending on the brand and whether the product is natural or has added ingredients. For example, natural peanut butters with just peanuts and a little salt may have a slightly different protein-to-calorie ratio than versions with added sugar or hydrogenated oils. Protein-enriched peanut butters are also available, which can contain significantly more protein per serving, sometimes up to 7 grams per single tablespoon. For the most accurate information, it is always best to check the nutritional label of the specific product you are consuming.
The Complete Nutritional Profile of Peanut Butter
Beyond its protein content, peanut butter is a nutrient-dense food that provides several other vitamins, minerals, and healthy fats essential for overall health.
Other Key Nutrients in a 2-Tablespoon Serving:
- Magnesium: Essential for muscle function and energy production.
- Phosphorus: Crucial for building healthy bones and cells.
- Zinc: Supports immune function and protein synthesis.
- Niacin (Vitamin B3): Aids in digestion and nerve function.
- Vitamin B6: Plays a vital role in over 100 enzyme reactions.
- Vitamin E: A powerful antioxidant that protects against cellular damage.
These nutrients, combined with the healthy fats and fiber, contribute to peanut butter's ability to promote satiety and help manage blood sugar levels, making it a valuable part of a balanced diet.
Peanut Butter vs. Other Protein Sources
While peanut butter is a good plant-based protein source, its protein-to-calorie ratio is different compared to animal-based options. Here is a comparison of the protein content in a standard portion of various foods:
| Food (Standard Serving) | Serving Size | Approximate Protein (g) | Type of Protein | 
|---|---|---|---|
| Peanut Butter | 2 tablespoons | 7–8 g | Plant-Based | 
| Large Egg | 1 egg | 6 g | Animal-Based (Complete) | 
| Greek Yogurt | 6 ounces | 9–20 g | Animal-Based (Complete) | 
| Chicken Breast | 3 ounces | 26.5 g | Animal-Based (Complete) | 
| Lentils (cooked) | 1 cup | 18 g | Plant-Based | 
| Tofu (firm) | 1/4 block | 15 g | Plant-Based (Complete) | 
| Almonds | 1/4 cup | 7 g | Plant-Based | 
How to Incorporate Peanut Butter into a High-Protein Diet

The Role of Peanut Butter in Health and Fitness
Peanut butter's combination of protein, healthy fats, and fiber makes it beneficial for several health aspects.
- Weight Management: Its satiating properties can help curb hunger and reduce overall calorie intake throughout the day.
- Heart Health: The monounsaturated and polyunsaturated fats help lower bad cholesterol (LDL) and reduce the risk of heart disease.
