I've been looking for a hearty but healthy meal replacement for busy mornings lately, and I finally found the soy milk of my life. I usually prefer the honest taste of whole ingredients over store-bought soy milk loaded with sugar, so when I kept seeing great reviews for 'Garuseonsaeng Seoritae Yak-kong 99.3 drinkable soy milk' on Instagram and blogs, I had to try it myself!

I was looking for a low-sugar soy milk I could have as a diet-friendly breakfast replacement, and after trying it, I actually drink it regularly now. Unlike liquid soy milk, it's a powder type you mix fresh whenever you want, which made it a lot more appealing. Let me break down the full review! + it dissolves well even in cold water, which is great.

## The ingredients: 99.3% yak-kong beans, 0.7% sea salt

Garuseonsaeng Seoritae Yak-kong 99.3 is made by grinding Korean yak-kong (small black soybeans) whole, unpeeled, resulting in a product that's 99.3% yak-kong with absolutely no emulsifiers, preservatives, flavorings, or sugar added — a 100% pure plant protein drink. Made from only 99.3% Korean yak-kong and 0.7% Korean sea salt, it felt like something I could trust for health management, diet plans, or even as a snack for pregnant women and children.

Whether you're choosing a soy milk for a busy morning meal replacement, a healthy snack, or a low-sugar option, you shouldn't just look at the 'no additives' label — you need to carefully check what kind of beans were used, how much, and how convenient it is to drink. A lot of soy milk products on the market add sugar or flavoring to force in sweetness, so checking the purity of the ingredients really matters.

Personally I prefer nutty soy milk over sweet soy milk, so Garuseonsaeng Seoritae Yak-kong suited me well. Since it's unsweetened, if you like things sweet, keep that in mind — there's no sweetness at all.

## How to mix it in cold water, and the nutrition per serving

Just add 2 scoops (about 30g) with the included measuring spoon to a glass of water (150-180ml), stir well before drinking, and you're done. Powder products that don't dissolve well in water tend to be annoying enough that you stop bothering to make them, but this one dissolves really well even in cold water, so it's super easy to mix. (If it's a hassle, you stop eating it. But since it dissolves so easily in cold water, I end up having it every morning.)

- It's good cold or mixed warm — the deep flavor of the whole bean comes through either way, so it works all year round.
- At 132kcal per 30g serving, it's not a heavy calorie load, and with 13g of protein (24%) it makes a filling breakfast replacement or healthy snack.

## Unsweetened, but how does it taste? Nutty like kongguksu broth

Honestly, I was a little worried that 'unsweetened, no additives' might mean it'd taste bland or beany. But the moment I mixed it with water and took a sip, I was genuinely surprised. It really was like drinking rich, nutty kongguksu (cold soy noodle soup) broth — the deep, robust nuttiness of the bean itself spread through my whole mouth!

How can something with no sugar or artificial additives taste this nutty and delicious... If you're someone who loves kongguksu or thick soy bean broth, this is an automatic yes, yes, yes. I'm a complete yes times 1000. There's zero beany off-taste — it's clean and nutty, and I never get tired of it, so I drink a cup every single morning.
