Tea is one of the most popular beverages worldwide, but its protein content is often overlooked. While a standard cup of brewed tea contains only trace amounts of protein, certain teas—especially matcha, powdered green tea, and some herbal blends—can contribute a small but meaningful amount to your daily intake. This calculator helps you estimate the protein in your tea based on the type, serving size, and preparation method.
Whether you're tracking macros, following a plant-based diet, or simply curious about your favorite brew, this tool provides quick, accurate estimates. You can choose from common tea types, adjust the serving size, and even account for added milk or protein powder. The result includes a breakdown of protein per serving and per 100 ml, making it easy to compare different teas and fit them into your nutrition plan.

How to Use This Tool
Start by selecting the type of tea you're drinking from the dropdown. The calculator includes common varieties like green, black, oolong, white, herbal, matcha, chai, and bubble tea. Next, enter your serving size and choose the unit (ml, cups, or fluid ounces). If you add milk, select the type and amount—dairy, soy, or almond—and specify whether the amount is in milliliters or tablespoons. Finally, if you stir in protein powder, enter the grams. Click Calculate to see your total protein, plus a breakdown showing how much comes from the tea itself, from milk, and from any added powder.
For quick estimates, a standard cup is 240 ml, and a typical milk splash is about 30 ml (2 tablespoons). You can adjust these to match your actual serving.
How It Works
The calculator uses average protein values per 100 ml for each tea type. Brewed teas (green, black, oolong, white) contain roughly 0.1 g per 100 ml, while herbal teas are essentially protein-free. Matcha, because it's made from whole powdered leaves, provides about 0.5 g per 100 ml. Chai and bubble tea have slightly higher values due to added milk and other ingredients.
For milk, we use standard protein content per 100 ml: dairy (2%) has about 3.4 g, soy milk about 3.3 g, and almond milk about 0.6 g. The calculator multiplies these values by your milk amount and adds them to the tea's protein. Protein powder is added directly in grams.
The formula is simple: Total protein = (tea protein per 100 ml × tea volume / 100) + (milk protein per 100 ml × milk volume / 100) + protein powder. The per-100 ml figure is then calculated by dividing total protein by the total serving volume and multiplying by 100.
Worked Examples
Example 1: Plain Green Tea
You drink 300 ml of brewed green tea with no milk or powder. Tea protein = 0.1 × 300 / 100 = 0.3 g. Total = 0.3 g. Per 100 ml = 0.1 g.
Example 2: Matcha Latte with Soy Milk
You make a matcha latte with 200 ml of water and 50 ml of soy milk. Matcha protein = 0.5 × 200 / 100 = 1.0 g. Soy milk protein = 3.3 × 50 / 100 = 1.65 g. Total = 2.65 g. Per 100 ml = 2.65 / 250 × 100 = 1.06 g.
Example 3: Black Tea with Dairy Milk and Protein Powder
You have 240 ml of black tea, add 30 ml of dairy milk, and stir in 10 g of protein powder. Tea protein = 0.1 × 240 / 100 = 0.24 g. Milk protein = 3.4 × 30 / 100 = 1.02 g. Powder = 10 g. Total = 11.26 g. Per 100 ml = 11.26 / 270 × 100 ≈ 4.17 g.
Tips & Best Practices
- For accurate tracking, measure your tea and milk with a kitchen scale or measuring cup rather than estimating.
- If you use a different milk (e.g., oat, coconut, or skim), adjust the protein value manually—oat milk has about 1 g per 100 ml, coconut milk about 0.2 g, and skim dairy about 3.4 g.
- Matcha powder can vary in protein content by brand; check the label for exact numbers.
- Remember that tea protein is incomplete (lacking some essential amino acids), so pair it with other protein sources throughout the day.
Factors Affecting Accuracy
Protein values are averages and can vary by brand, brewing time, and leaf quality. For brewed teas, longer steeping may extract slightly more protein, but the difference is minimal. For matcha, the grade and amount of powder used significantly affect protein content—ceremonial grade may have more than culinary grade. Milk protein content also varies by brand and fat content. This calculator provides a good estimate for planning purposes, but for precise tracking, refer to the nutrition labels on your specific products.
Frequently Asked Questions
Does tea really contain protein? Yes, but in very small amounts. A typical cup of brewed tea provides less than 0.5 g of protein, which is negligible for most people. Matcha and teas with added milk or powder contribute more.
Can I use this calculator for iced tea? Yes, as long as you enter the total volume of the iced tea. The protein content is the same as hot brewed tea.
Is tea protein good for muscle building? Tea protein is not a significant source for muscle building due to its low quantity and incomplete amino acid profile. It's better to rely on foods like eggs, chicken, beans, or protein shakes. For more on plant-based protein, see our bean protein calculator.
How does matcha compare to coffee in protein? Matcha has slightly more protein than coffee (which has about 0.1 g per 100 ml), but both are minor contributors. If you're tracking protein, focus on your main meals and snacks.
