How Many Calories Are in 1 Tablespoon of Collagen Powder?

November 12, 2025 •

3 min read

A single gram of protein contains approximately 4 calories, and since collagen is a pure protein source, it contains calories. A typical serving often has a higher calorie count than people expect because most standard scoops hold significantly more powder than one tablespoon.

Quick Summary

The calorie count for 1 tablespoon of collagen powder is not fixed, typically ranging from 30 to 70 calories depending on the brand and weight per serving. The calories are derived exclusively from protein, as pure collagen powder contains virtually no fat or carbohydrates.

Key Points

Variable Calories: Calories in 1 tablespoon of collagen powder range from approximately 30 to 70, depending on the specific brand and weight density.
Check the Label: Always verify the exact calorie count on the product's nutritional information, as serving sizes (and weight per tablespoon) vary significantly.
Protein-Based Calories: The calories in pure, unflavored collagen powder are derived almost entirely from its protein content, with virtually no fats or carbohydrates.
Consider Serving Size: Be aware that the scoop included with many brands' products is often larger than a standard 1-tablespoon measurement, which directly impacts the total calorie intake.
Supports Weight Management: Due to its high protein and low overall calorie count, collagen can be a good supplement for those managing their weight and controlling appetite.
Flavor Impacts Calories: Flavored collagen powders may contain extra calories from added sugars or other ingredients, unlike unflavored varieties.

Factors Affecting Calories in Collagen Powder

The number of calories in a tablespoon of collagen powder is not a single, fixed number. Several factors cause the count to vary, most notably the density of the powder and the specific formulation used by different manufacturers. Understanding these nuances is crucial for accurate calorie tracking, especially if you are managing your weight or following a specific diet plan.

Weight vs. Volume: The Tablespoon Dilemma

One of the most significant sources of variation is the difference between measuring by weight and by volume. A tablespoon is a unit of volume, but the weight of the powder that fits into that volume can differ based on its density, fineness, and how packed it is. For example, some brands recommend a serving size that is 10 grams and delivers around 40 calories, while other brands' standard scoops contain 20 grams, which can provide 70 calories or more. Furthermore, the scoop provided with the product is often larger than a standard kitchen tablespoon, leading to further discrepancies. Always use a food scale for the most accurate measurement if precision is a concern.

Brand and Formulation Variations

Different collagen powders have different compositions that can influence their caloric content. While pure, unflavored collagen peptides contain calories only from protein, some flavored or specialized products may have additional ingredients that add to the calorie count. These can include sweeteners, natural flavorings, or other supplements mixed in for specific health benefits. It is vital to read the nutrition label of your specific product to see exactly what you are consuming.

The Low-Calorie Protein Advantage

Collagen powder can be a low-calorie and versatile addition to almost any diet. As a pure protein source, it contributes to your daily protein intake without adding fat or carbohydrates. This makes it an excellent option for those focused on high-protein, low-calorie diets, including keto diets. Its role in promoting satiety can also help manage appetite, potentially aiding in weight loss efforts. Unlike many protein shakes that contain added sugars and high-calorie ingredients, unflavored collagen powder offers a clean source of protein that can be seamlessly incorporated into various beverages and recipes without altering flavor.

Integrating Collagen into Your Daily Routine

Morning Coffee: Stirring a tablespoon or scoop of collagen powder into your morning coffee or tea is a popular and easy way to start your day with a protein boost. It dissolves well in hot liquids and is typically tasteless and odorless, making it a simple addition.
Smoothies and Shakes: For a more substantial boost, add it to your post-workout or breakfast smoothie. It blends easily and increases the protein content, contributing to muscle repair and a feeling of fullness.
Baked Goods: Collagen powder can be mixed into recipes for muffins, pancakes, and cookies to increase their protein content without significantly changing the texture or flavor. Note that baking may degrade some nutritional properties, but it's still a viable option.
Soups and Sauces: For those looking for a savory application, collagen powder can be mixed into soups, broths, and sauces to thicken them and add a nutritional kick.

The precise number depends on the brand, the size of the scoop, and whether it contains any additional ingredients.

For anyone watching their caloric intake, reading the product's nutrition label is the most reliable method for accurate tracking.
