I know I should eat breakfast, but putting together a proper meal every day is harder than it sounds, right? By the time I cook rice, pull out the side dishes, and wash up, it feels like my energy is already gone for the day.
So I find myself looking for easy meal replacements or healthy snacks, and soy milk is a pretty approachable option. But when you actually try to choose one, there are so many kinds: sweet soy milk, black-bean soy milk, unsweetened soy milk, and products that emphasize protein.
When I choose soy milk, I tend to look beyond whether it simply says “unsweetened” or “sugar-free.” I also check which beans it uses, how the ingredients are put together, and whether it is easy to have.
That is how I found Garu Teacher Drinkable Fresh Soy Milk White Soybean 99.3. Unlike regular soy milk in cartons, it comes as a powder that you mix with water. What caught my eye was that it contains 99.3% Korean white soybeans and 0.7% solar sea salt, with no added sugar.
What are the ingredients in Garu Teacher White Soybean?
Ingredients are the first thing I check when choosing soy milk. Even products described as “healthy soy milk” can have more ingredients than you might expect once you look closely. Garu Teacher Drinkable Fresh Soy Milk White Soybean 99.3 has a simple ingredient list.
99.3% Korean white soybeans and 0.7% solar sea salt. That is it.
It is said to contain no refined sugar or sugar substitutes, emulsifiers, preservatives, flavorings, or colorings. That can be an important standard when choosing something to eat every day. For people like me who look at the ingredient label on the back before the front of a package, this kind of simplicity is very welcome. One of the little pleasures of food shopping, perhaps. The age when you end up looking at the back rather than the pretty packaging… (?)
If you are used to sweet carton soy milk, it may feel a little unfamiliar at first. But because artificial sweetness usually feels overwhelming to me, I liked its clean soy milk flavor.

Ground whole Korean white soybeans!!
White soybeans are the familiar yellowish beans we generally think of as soybeans. This product is said to be a powder made by grinding whole, skin-on Korean white soybeans, with a 99.3% soybean content. Since soybeans are the main ingredient, you can expect the distinctive nutty flavor of white soybeans.

Above all, if using Korean-grown beans matters to you, it is a plus that you can check the country of origin before choosing it. There are so many soy products these days that I think it is better to look at the beans’ origin and percentage rather than choosing based only on the name “soy milk.”

Soy milk powder mixed with cold water
Garu Teacher comes in powder form, so you drink it by mixing it with water.



I mixed two measuring scoops (30g) into 180ml of bottled water. Perhaps because the powder is so fine? This must be what food technology is, haha.

It also dissolves well in cold water, which is convenient because you do not have to go through the trouble of preparing warm water.

You can scoop out only as much as you need and mix it whenever you want a drink at home, and its storage and uses offer slightly different advantages from carton soy milk. On mornings when time is short, you can simply mix it with water and drink it, so it seems suitable as a breakfast replacement too.

Of course, there is one point to consider here. If you think, “Even mixing powder is too much work—I just want to stick in a straw and drink right away!” then cartons may suit you better. If, like me, you want to adjust the thickness to your liking or use it like kongguksu-style soy broth at home, powder may be more convenient. The important thing is whether it suits your lifestyle.

What to check when choosing unsweetened soy milk
A lot of people are looking for unsweetened or sugar-free soy milk these days. Still, rather than choosing based only on the words “unsweetened” or “sugar-free,” it is best to check the actual ingredients and nutrition information too.
Garu Teacher Drinkable Fresh Soy Milk White Soybean 99.3 has no added sugar, and its ingredients are simply white soybeans and solar sea salt. That means it may suit people who want the mild, nutty flavor of soybeans rather than sweetness. On the other hand, if you buy it expecting sweet soy milk, it may taste different from what you had in mind, so it is worth knowing that in advance.
I actually think this kind of product is useful in many ways. You can drink it mixed with water, adjust the thickness to your taste, or use it with other foods.
Nutrition information per 30g serving
The nutrition information for Garu Teacher Drinkable Fresh Soy Milk White Soybean is based on a 30g serving. One 30g serving has 130kcal and 11g of protein, so the ease of getting protein with a meal also stood out to me.


It may be worth a look if you are...
- Looking for soy milk with no added sugar
- Prefer unsweetened soy milk
- Looking for a product made with Korean-grown beans
- Find sweet carton soy milk too cloying
- Looking for an easy breakfast replacement
- Looking for soy milk powder that dissolves well in cold water
- Want to make soybean drink easily at home
- Prefer foods with simple ingredients
Conversely, if you like sweet soy milk or even find mixing it with water bothersome, regular carton soy milk may be more convenient. It seems that soy milk choices also depend on your taste and daily routine.
Check these before buying soy milk
If I were buying soy milk, I think I would check about four things. First, the origin and percentage of the beans. Second, whether sugar or sugar substitutes have been added. Third, the ingredient makeup, including emulsifiers, flavorings, and colorings. Finally, whether it comes in a form I can keep having consistently.
By those standards, Garu Teacher Drinkable Fresh Soy Milk White Soybean 99.3 has simple ingredients, a high proportion of Korean white soybeans, and a powder format. Comparing it with the standards you have used for soy milk so far should make the choice much easier.
If you know you should eat something in the morning but a full meal feels like too much, and you are looking for a mild, unsweetened soybean drink, Garu Teacher is worth adding to your list. A simple cup can be surprisingly filling, after all. A daily morning wellness routine will not last if it is too elaborate. Something simple and easy to reach for—that may be the secret to consistency, right?
