About Unsweetened Matcha Green Tea

One cup of unsweetened matcha prepared with approximately one teaspoon, or 2 grams, of pure matcha powder provides about 6 calories, 0.6 grams of protein, 1.1 grams of carbohydrate, 0.1 grams of fat, and 0.7 grams of fiber. The exact composition varies with tea grade, growing conditions, and the measured weight of the powder.

Unlike ordinary brewed green tea, matcha is consumed as a suspension of the entire ground leaf. It therefore supplies small amounts of fiber, vitamin K, minerals, chlorophyll, catechins, caffeine, and L-theanine. Its estimated glycemic load is effectively zero when no sugar or milk is added.

Matcha is not a substantial source of food energy or protein, but it is a nutrient-conscious alternative to sweetened tea and coffee drinks. Nutrition values in this entry assume pure unsweetened powder and water, not a latte, premixed sachet, syrup, honey, or sweetened creamer.

Key Health Benefits

  • 1

    Matcha contains the whole finely ground tea leaf, providing catechins and other polyphenols in a concentrated form.

  • 2

    A standard unsweetened serving contributes very few calories and less than one gram of net carbohydrate.

  • 3

    Its natural combination of caffeine and L-theanine can support alertness while producing a different subjective effect from coffee.

  • 4

    Replacing sweetened café drinks with water-based matcha can substantially reduce added-sugar and calorie intake.

  • 5

    The small amount of leaf powder contributes fiber and micronutrients that are largely absent from ordinary filtered tea.

Expert Tip

Whisk pure unsweetened matcha into hot, but not boiling, water. Avoid sweetened matcha mixes, which may contain much more sugar than tea powder, and adjust the serving or timing if caffeine affects sleep, anxiety, reflux, or heart rate.
