## In short

Heorissok Diet Dark Americano is a stick-type diet coffee made with garcinia cambogia extract, registered as a health functional food and taken as one stick dissolved in 250-300ml of water per day. Each Heorissok Diet stick holds 3,000mg with 750mg of HCA, and one box has 30 sticks, so a 30-day supply is easy to track, while the individual wrappers make it simple to slip one stick into a bag. For anyone who would rather drink garcinia than swallow a pill, Heorissok Diet Dark Americano is worth comparing.

When it comes to sticking with a health functional food, I've found that how you take it matters almost as much as what's in it. I've been looking for something I could drink like a regular beverage instead of swallowing pills or capsules, so I tried Heorissok Diet Dark Americano.

It's an Americano-style diet coffee with garcinia cambogia extract, and you mix one stick into water each day.

Each box has 30 sticks, so it's easy to calculate how much you're supposed to take, and the individual stick packaging made it convenient to carry around too. Let me walk through mixing it with water, the amount per stick, the functional ingredient, and what to check before drinking it.

## What comes in the box: 30 Heorissok Diet sticks, individually wrapped

Heorissok Diet Dark Americano comes in a black and red box containing 30 stick packets. Each stick holds 3,000mg, and the daily dose is one stick. If you drink one a day, the box lasts exactly 30 days.

Opening the box, each stick is individually packaged, so there's no need to measure out a portion each time. There's an EASY CUT mark at the top of each stick so you can tear it open by hand.

- Net content: 3,000mg × 30 sticks
- Total content: 90g
- Daily intake: 1 stick per day
- Product type: Health functional food
- Flavor: Dark Americano

The box itself isn't bulky, and since you can pull out just what you need, I kept the box at home and carried individual sticks when heading out.

## How much garcinia cambogia extract? 750mg HCA per stick

Heorissok Diet contains garcinia cambogia extract, and one daily stick gives you a total of 750mg HCA. When choosing a product like this, it's more accurate to check what functional ingredient is included and how much, rather than just looking for the word 'diet' in the name.

The functional claim listed on the product is 'may help reduce body fat by inhibiting the conversion of carbohydrates into fat.' Since this is a health functional food, it's best not to expect immediate weight loss from a single cup — it's really meant to be taken alongside managed diet and exercise.

Per-stick nutrition info shows 10kcal, 2g carbohydrates, with protein, fat, and sodium all at 0g.

## How to take it: one stick in 250-300ml of water a day

Taking Heorissok Diet isn't complicated. Prepare a cup of water, tear open one stick, and stir well before drinking. The product instructions say to mix it into roughly 250-300ml of water depending on preference.

![Pouring a stick of diet coffee into a cup of water](https://img.superchart.com/images/garcinia-diet-coffee-dark-americano-stick/garcinia-diet-coffee-dark-americano-stick-08-x7fna-900.webp)

Inside the stick is a brown powder. When it first hits the water it spreads across the surface, but stirring with a spoon gradually blends it into a deep brown color throughout.

- Prepare 250-300ml of water
- Add 1 stick
- Stir thoroughly and drink
- Take only once a day

If measuring water is a hassle, it helps to check the capacity of your usual cup ahead of time. Since all you need is a cup and water — no multi-step prep — it wasn't hard to build a routine around drinking it at the same time each day.

## How does the Dark Americano flavor taste? Made with Colombian coffee powder

What sets Heorissok Diet apart from typical garcinia tablets is that you dissolve it in water like coffee instead of swallowing a pill. The ingredients list Colombian coffee powder, and the product itself is named Dark Americano flavor.

Once mixed with water, the color is a deep brown similar to a regular Americano. That said, it's better to think of it as a health functional food with garcinia cambogia extract rather than expecting it to taste exactly like regular brewed coffee just because of the name.

If you find pills a hassle or simply prefer drinking your supplements, the difference in method is clear here. Tearing open one stick per cup also means there's no dosage math to do.

## Precautions to check before taking Heorissok Diet

Heorissok Diet's standard is once a day, one stick at a time. Since it's a health functional food, it's important to check the recommended intake and precautions too. It's not meant to be taken in multiple sticks at once — sticking to the set dose matters.

![Label showing intake amount and precautions](https://img.superchart.com/images/garcinia-diet-coffee-dark-americano-stick/garcinia-diet-coffee-dark-americano-stick-11-qv9qf-899.webp)

The product also lists the following precautions:

- Avoid if you are a child, pregnant, or breastfeeding
- Consult a specialist if you have liver, kidney, or heart conditions, allergies or asthma, or are taking medication
- Men should avoid excessive intake
- Stop taking it and consult a specialist if any adverse symptoms occur

For storage, keep it somewhere cool, away from high heat, humidity, and direct sunlight. If you have a specific condition or are taking medication, it's important to check the precautions on the label first rather than diving in just because it's marketed for weight management.

## Is Heorissok Diet right for you if you prefer drinking garcinia like coffee?

What stood out most about Heorissok Diet Dark Americano was that it felt less like taking a separate supplement and more like drinking a regular beverage mixed with water.

![A stick and a cup of diet coffee side by side](https://img.superchart.com/images/garcinia-diet-coffee-dark-americano-stick/garcinia-diet-coffee-dark-americano-stick-12-xf2yd-900.webp)

Each stick has 750mg HCA, and with 30 sticks for 30 days, managing your daily intake is simple. Since each stick is individually packaged, there's no need to portion anything out yourself.

On the other hand, if you're really after regular brewed coffee, it's worth separating that expectation from what this product actually is. The point here isn't a coffee substitute — it's garcinia cambogia extract delivered in a dark Americano format.

If you get on better with a drink than a pill and want a consistent daily dose of garcinia, Heorissok Diet's 30-stick box and intake method are worth comparing against other options.
