Have you heard of Garuseonsaeng Seoritae Drinkable seoritae (Korean black soybeans)? I’d heard of Garuseonsaeng Seoritae Drinkable seoritae and matcha a few times, but this was my first time trying Heukseon, their premium black seonsik (a grain-based meal powder)! 🖤 I’d recommend this powder to anyone who says, “I absolutely need breakfast!” “I’m looking for a protein shake!” or “I want a meal powder with good ingredients!”

It turns out this is already a well-known brand for diet meal powders, black-food meal powders, and shakes?! Even the name Garuseonsaeng Seoritae Drinkable inspires trust, right?
Looking at the powder first, it has that “Is this misutgaru (mixed grain powder)?” kind of look! It also smelled like misutgaru plus roasted black beans. I spent a lot of time wondering which kind of powder I should try.

Why I chose Heukseon
- It has the highest protein content: 13g 🖤
- 100% natural ingredients, with no synthetic additives 🖤
- A base of 100% Korean black grains 🖤
Those points made me think, “I can’t not try it!”—so I chose Garuseonsaeng Seoritae Drinkable Heukseon. Their seoritae, black sesame, matcha, Heukseon, small black bean, and mugwort powders are popular in that order!

Zipper-bag packaging and measuring scoop
Plus, it comes in a convenient zipper bag, so there’s no need to transfer it into a separate container! The included plastic measuring scoop is made to fit inside the zipper bag too. After measuring, I just popped it back in the bag and stored it away—so convenient! 🥄

A healthy, convenient meal based on 100% plant protein from whole natural ingredients rather than synthetic additives! 🖤 I thought it would be perfect as a diet-friendly dinner replacement, but it was more filling than expected, so I really liked it for breakfast! The flavor is deep and substantial. With just 2.3g of sugars, it is barely sweet at all; instead, it tastes nutty and rich.

My milk ratio and preferred thickness
The directions are 2 included scoops (30g) plus one glass of milk (180ml). I tried it with cold milk, and it dissolved well even in cold milk; a few shakes mixed it evenly, so it was easy!

For me, 1.5 scoops in about one mug of milk gave the perfect thickness. Two scoops was fairly thick, so it tasted better when mixed to a consistency that went down smoothly, like misutgaru. But apparently you can make it thick and use it as a healthy salad dressing too!! I think it would be delicious that way as well.

For children, it may be better to make it thinner
Because the powder has some texture, I think it would be better to mix it more thinly for children. One glass of milk plus 1.5 scoops. If you get it wrong, it can feel a little scratchy going down. It was no problem at all for me as an adult, but for children, I thought it would be good to have them gulp it down and give them a glass of water afterward!

Put it in a tumbler and give it just three or four light shakes, and it mixes evenly like this!
I always mix it into milk like misutgaru, and it has that nutty flavor and distinctively savory-nutty black soybean taste! It is so plain and clean-tasting that you can tell no sugar was used at all. Maybe because it is a diet meal powder, high-protein meal powder, and sugar-free meal powder, but my parents enjoyed it too.

Ingredients and a flavor I want to repurchase
When I looked at the ingredients list, the ingredients were so good that I thought there would be no need to buy other protein drinks—this might be the healthiest way to get protein! They especially recommend it for people wanting fuller-looking hair, more resilient hair, and nutritional support!
Black foods rich in anthocyanins, naturally occurring antioxidants! 🖤 I truly recommend it if you want protein with health in mind! Actually, my dad liked it so much more than I did that I’m planning to buy another pack once we finish it.

There are lots of other flavors, so I’ll think about them, but I suspect I’ll buy Garuseonsaeng Seoritae Drinkable Heukseon again. Because first of all, it is so delicious!! I don’t like artificially sweet flavors, and this has a natural, savory-nutty taste—like soy milk..? MIsutgaru..? Black-bean-flavored misutgaru..? It is really delicious! A flavor both my dad and I love.. 🖤
