Kale Boost Tea at a Glance

What Is HeyTea Kale Boost Tea?

Kale Boost Tea is a blended, iced drink that combines fresh kale with fruit, chia seeds, and brewed jasmine green tea. HeyTea groups it with its superfood and fruit teas rather than its milk teas or cheese teas, so there is no creamer, milk, or cheese foam on top.

The idea is simple: a green juice with a tea backbone. The kale gives the drink its bright green color, while the grapes, apple, and lemon do most of the work on flavor.

HeyTea itself is a Chinese tea brand founded in 2012 and based in Shenzhen. It opened its first US store on Broadway in New York in December 2023 and has since expanded to the West Coast, starting with a Beverly Hills location in July 2024. Kale Boost Tea is now listed across many US stores, including locations in California, New York, and New Jersey.

Kale Boost Tea Ingredients

HeyTea’s own menu description on delivery platforms lists six components:

• Kale
• Chia seeds
• Green grapes
• Apples
• Lemons
• Jasmine green tea

Real cane sugar is added based on the sweetness level you pick, unless you choose the zero-calorie sweetener or no added sugar.

A Note on Conflicting Ingredient Lists

You may see some websites describe Kale Boost Tea as containing ginger, or list “freshly squeezed juice” without naming the fruit. We could not find ginger in HeyTea’s current US menu listing, so we have left it out. Recipes can differ slightly between countries and can change over time, so if you have a specific allergy or intolerance, confirm the ingredients with staff at your store.

What Does Kale Boost Tea Taste Like?

Most people are surprised by how fruity it is. The green grape and apple dominate, the lemon adds a sharp edge, and the jasmine tea gives a light floral finish. The kale reads as a fresh, grassy note in the background rather than a bitter, leafy one.

Reviews reflect that. A student reviewer at a Bay Area high school newspaper said they could not really taste the kale at all and that it came across mostly as fruit juice. On social media, customers regularly describe it as a mix of apple, grape, and lemon with a “green” freshness.

The chia seeds add a light, slightly gel-like texture. If you dislike seeds in your drinks, you can order it without them (more on that below).

How Many Calories Are in Kale Boost Tea?

This is where most websites get it wrong, so it is worth being precise.

HeyTea has not published an official calorie count for Kale Boost Tea on its US menu. The figures you see online come from third-party sites, calorie-tracking apps, and customer posts, and they do not agree:

A realistic range for a standard cup is roughly 110 to 210 calories, depending mostly on sweetness level.

One more thing to watch for: some Australian menu pages list the drink at “572 Cal.” Australian food labels use kilojoules, and 572 kJ converts to about 137 kcal, which fits neatly into the range above. If you see a number in the 500s, it is very likely kilojoules rather than calories.

What Changes the Calorie Count

If you are tracking intake closely, the lowest-calorie version is usually minimal sugar or a zero-calorie sweetener option, with chia seeds left in or removed depending on whether you want the fiber.

Kale Nutrition Facts (USDA Data)

Since kale is the star ingredient, many people want to know what it actually contributes. The figures below come from the USDA FoodData Central entry for raw kale (FDC ID 168421) and are per 100 grams, which is roughly 4 to 5 loosely packed cups of chopped leaves.

*Daily Values are based on the FDA reference amounts for a 2,000-calorie diet.

How Many Calories in Kale?

Raw kale has 35 calories per 100 grams. In everyday terms, one cup of loosely packed raw kale (about 21 g) comes to only about 7 calories. A firmly packed cup of chopped kale weighs more, around 67 g, and works out to roughly 23 calories.

Some older nutrition sites still show 49 calories per 100 g. That number comes from an earlier USDA dataset; the current USDA entry lists 35 kcal.

How Many Carbs in Kale?

Kale contains 4.4 g of total carbohydrates per 100 g, and 4.1 g of that is fiber. That leaves well under half a gram of net carbs per 100 g, which is why kale is popular with people following low-carb or keto diets. A loosely packed cup has less than 1 g of total carbs.

Keep in mind that the carbs in Kale Boost Tea come mostly from the fruit and any added sugar, not the kale.

Kale Nutritional Value in Plain Terms

Kale’s nutritional value is concentrated in its vitamins rather than its calories:

• Vitamin K is the standout. A 100 g serving covers more than three times the daily value.
• Vitamin C is also high, exceeding the daily value per 100 g.
• Calcium is notable for a leafy green, at about a fifth of the daily value.
• Fiber is solid for such a low-calorie food.

How much of this ends up in your cup depends on how much kale is blended in, which HeyTea does not disclose. Blending keeps more of the fiber than pressing or straining does, and the Extra Kale Boost option simply puts more of the vegetable in the drink.

One practical note: because kale is very high in vitamin K, anyone taking a blood thinner such as warfarin should talk with their doctor before making kale drinks a regular habit, since consistent vitamin K intake matters with that medication.

Kale Tea vs. Kale Boost Tea

People searching for “kale tea” are usually looking for one of two different things.

So Kale Boost Tea is really closer to a green juice or smoothie with tea than a traditional steeped kale tea.

How to Customize Your Kale Boost Tea

HeyTea’s US menu offers a surprising number of adjustments for this drink. Here is what is currently available, based on HeyTea’s own options on delivery platforms:

Best Orders by Goal

• Lowest calories: Minimal Sugar, or any zero-calorie sweetener option.
• Matcha lovers: Replace the jasmine green tea with matcha for a grassier, more tea-forward cup.
• No caffeine: Choose the tea-free option, which also makes it a reasonable evening drink.
• More “green” taste: Add Extra Kale Boost and keep sugar at Light or Minimal so the fruit does not mask it.
• Smoother texture: Order it without chia seeds.

Caffeine, Allergens, and Dietary Notes

Caffeine: The standard version contains caffeine from jasmine green tea. HeyTea does not publish a milligram figure for this drink. Green tea generally has less caffeine than coffee, but if you are sensitive, the tea-free option removes it entirely. The matcha swap still contains caffeine.

Dairy: None of the listed ingredients contain dairy. However, HeyTea stores prepare milk teas and cheese foam drinks, so cross-contact is possible. If you have a serious milk allergy, ask the store.

Chia seeds: Chia is included by default. Anyone with a seed allergy or sensitivity should order it without chia seeds.

Citrus: Lemon is part of the recipe, so people who react to citrus should avoid this drink.

Vegan and plant-based: Based on the listed ingredients, the drink is plant-based, though HeyTea does not label it as certified vegan.

Kale Boost Tea Price in the USA

HeyTea prices vary by city and by how you order.

• Delivery apps: On Postmates, Kale Boost Tea is listed at $10.49 at HeyTea’s Daly City (Westlake Center) and San Francisco (Downtown Metreon) stores as of October 2026. Delivery-app prices are often higher than in-store prices.
• In store: Prices are typically lower than on delivery apps. A 2025 student review from the Bay Area put HeyTea drinks at around $8 each in store, though exact prices depend on location and can change.

For reference, HeyTea stores in Toronto and Markham, Canada list the drink at CA$14.49 on DoorDash.

The most reliable way to check your local price is the HeyTea app or the delivery app for your nearest store. You can also browse the latest US drink lineup on our HeyTea menu homepage.

How to Make a Kale Boost Tea at Home

HeyTea does not publish its recipe, so this is a home-style version built around the drink’s listed ingredients. It will not taste identical, but it gets close and lets you control the sugar.

Makes 1 large glass (about 16 oz)

Ingredients

• 1 cup brewed jasmine green tea, chilled
• 1 cup loosely packed kale leaves, stems removed
• 8 to 10 green grapes
• 1/2 green apple, cored and chopped
• 1 tablespoon fresh lemon juice
• 1 to 2 teaspoons chia seeds
• 1 to 2 teaspoons cane sugar or simple syrup (optional)
• Ice

Steps

1. Brew the jasmine green tea with water just below boiling (around 175°F) for 2 to 3 minutes. Steeping longer can make it bitter. Let it cool completely.
2. Soak the chia seeds in 2 to 3 tablespoons of water for about 10 minutes, until they form a light gel.
3. Add the kale, grapes, apple, lemon juice, and chilled tea to a blender. Blend until completely smooth.
4. Taste and add sugar only if needed. The fruit is often sweet enough.
5. Strain through a fine sieve if you prefer a thinner, juice-like texture. Skip straining to keep more fiber.
6. Stir in the soaked chia seeds, pour over ice, and drink right away. Blended green drinks lose their color and freshness as they sit.

Tip: For a caffeine-free version, replace the tea with cold water. For a matcha variation, whisk 1 teaspoon of matcha into cold water and use that instead of jasmine tea.
