Is Boba Tea Usually High in Carbs?

Most teas generally contain zero carbohydrates. However, sugar, milk, and tapioca starch—three key ingredients in a standard cup of boba tea—have high levels of carbohydrates. All in all, the average 12-ounce bubble tea has approximately 70 grams of carbohydrates.

The recipe above is modified to avoid high amounts of carbs and calories. By replacing sugar with stevia, using keto-friendly pearls instead of traditional tapioca balls, and using cream instead of milk, this recipe brings the total carb count of the boba drink to under two grams!

Can You Have Boba Tea on a Keto Diet?

If you are refering to your typical glass of bubble tea—milk, sugar, tapioca pearls, and all—then no. Boba tea goes against the keto diet.

However, if you want to enjoy bubble tea on a keto diet, you can make use of this low-carb boba tea recipe above as a delicious and familiar substitute.

What Are Keto Boba Pearls Made From?

Keto boba pearls are made from gelatin and healthy oil. These products are carbohydrate-free and are delicious alternatives to the beloved chewy tapioca balls. They are typically gluten-free but not vegan. Many varieties are made with beef gelatin.

Regular tapioca pearls are coated in brown sugar or honey, which aren’t keto-friendly. However, keto boba pearls are coated with stevia, erythritol, or monk fruit sugar, which are all low-carb, low-calorie sugar alternatives.

What Bubble Milk Tea Toppings Are Low-Carb?

You can enjoy a few low-carb bubble tea toppings alongside your keto boba tea.

These include the following:

  • Chia seeds
  • Low-sugar aloe jelly
  • Unsweetened grass jelly
  • Watermelon cubes
  • Strawberry slices

While the toppings above are low in carbs, they’re not entirely carb-free. The safest option for a strict keto diet would be to skip the toppings altogether.
