Korean Diet Supplement Ranking TOP 20 | Why Protein Shakes Dominated the Top Spots
Top 20 Korean Diet Supplements | Why Protein Shakes Dominated the Rankings
Two numbers—“easy to drink” and “3,900 won”—have rewritten the map of the rankings.
Open the diet supplement rankings on Korea’s review platform Glowpick (as of April 2026), and one fact immediately stands out. The top spots are almost entirely filled by protein shakes from Delight Project. Natti Choco is in first place, Corn Castella in second, and Black Sesame Injeolmi in fourth. Three flavors from the same brand occupy three of the top four spots.
At YEPPURIKO, we regularly monitor Glowpick’s rankings and continue tracking changes in local reviews. From that perspective, we’ll examine why this particular top 20 has emerged.
The key point: The winner of the Korean diet supplement rankings was not a “specialized supplement that seems like it will work,” but a “delicious protein shake that’s easy to continue drinking every day.”
Why Delight Project’s Protein Shakes Dominated the Top Spots
The answer is simple: they’re affordable and they don’t taste bad.
One 45g packet costs 3,900 won. At just under 500 yen, the price feels more like a convenience-store drink than a supplement. In addition, when a 1+1 sale is offered at Olive Young (Korea’s leading H&B store), users rush to stock up. The purchasing pattern of “buying in bulk during sales” drives up the number of reviews.
And then there’s the taste. Reviews repeatedly mention that “it doesn’t have that strange protein taste” and that “it’s easy to drink, like Chocoemon (chocolate milk).” Most people who give up on protein shakes do so because of the taste. Eliminating that hurdle is directly reflected in the rankings.
The Shift from “Losing Weight with Supplements” to “Replacing a Meal”
This ranking accurately reflects what Korean consumers are looking for. They are not seeking a magic solution, but a realistic meal-replacement option.
The fact that three of the four products from first to fourth place are Korean-made protein shakes shows that the idea of “losing weight by taking supplements” is no longer mainstream. Instead, people replace breakfast or snacks with a protein shake to naturally reduce their calorie intake. It reflects the idea that ease of continuation produces results.
The range of flavors is also interesting. Natti Choco, Corn Castella, and Black Sesame Injeolmi. The latter two are flavors inspired by traditional Korean treats, designed not as “diet foods you have to force yourself to drink,” but as “rewarding replacements.” This type of flavor is also highly regarded as a distinctly local souvenir on the Korean Beauty Souvenir List.
Where Have the Garcinia Products Gone?
Of course, conventional supplements haven’t disappeared. In third place is Return Up’s “Fat Down Power Burn Master Garcinia” (10 100ml bottles, 24,000 won), while sixth place goes to Green Monster’s “Diet Special 2 Garcinia 900” (32,000 won).
What stands out in the reviews are comments such as “I take it when I’m eating a high-carbohydrate meal.” In other words, these products are shifting from everyday staples to an “insurance policy” used strategically on days when users expect to overeat. This refers solely to usage occasions; the products are foods, not medicines.
Foodology’s “Coleology Cutting Jelly” in fifth place (10 pieces, 23,900 won) fits the same context. It’s jelly or a drink rather than a tablet. The format is changing.
Three Trends Revealed by This Ranking
Ultimately, looking at the top 20 products together reveals the trends in the Korean diet supplement rankings.
The first is a polarization of price points. Protein shakes are “everyday products” priced at 3,900 won, while Garcinia products and jellies are “targeted products” in the 20,000–30,000 won range. Products in the middle price range are getting lost.
The second is that the taste barrier determines success or failure. The first thing mentioned in reviews is not efficacy, but taste. The simple fact that products people cannot continue using will not produce results has become the key selection criterion.
The third is brand concentration. Brands that can expand across flavors, such as Delight Project, are coming to dominate the rankings as a whole. The key is whether a brand can build a series, rather than simply produce a one-off hit.
In Conclusion
The #1 product was neither a special ingredient nor a premium supplement. For 3,900 won, it’s a delicious shake that’s easy to keep taking. That is Korea’s answer right now. The consumer mindset of choosing “something you can stick with” over “something that works” created this TOP 20.

Many users stock up during Olive Young’s (Korea’s leading H&B store) 1+1 sales. In addition to the affordable price of 3,900 won per bag, the effective price is essentially half off during sales.

One 45g packet costs 3,900 won. At just under 500 yen, the price feels more like a convenience-store drink than a supplement. When a 1+1 sale is also held at Olive Young (Korea’s major H&B store), users rush to stock up. The purchase pattern of “buying in bulk during sales” drives up the number of reviews.
And then there’s the taste. Reviews repeatedly mention that “it doesn’t have the strange taste typical of protein” and that “you can drink it like Chocoemon (chocolate milk).” Most people who give up on protein shakes do so because of the taste. Eliminating that obstacle is directly reflected in the ranking results.
The Shift from “Losing Weight with Supplements” to “Replacing Meals”
This ranking accurately reflects what Korean consumers are looking for. They aren’t seeking magic, but a realistic meal-replacement solution.
The fact that three of the four products from No. 1 to No. 4 are Korean protein shake products shows that the idea of “losing weight by taking supplements” is no longer mainstream. Instead, people replace breakfast or snacks with a protein shake to naturally reduce their calorie intake. It’s the idea that consistency produces results.
The flavor lineup is also interesting. Natti Chocolate, Corn Castella, and Black Sesame Injeolmi. The latter two are flavors of traditional Korean snacks, designed not as “diet foods you force yourself to drink,” but as “reward replacements.” These kinds of flavors are also highly regarded as local souvenirs in our Korean Beauty Souvenir List.
Where Did the Garcinia Supplements Go?
Of course, traditional supplements haven’t disappeared. Return Up’s “Fat Down Power Burn Master Garcinia” (24,000 won for 100ml × 10 bottles) ranks No. 3, while Green Monster’s “Diet Special 2 Garcinia 900” (32,000 won) ranks No. 6.
What stands out in the reviews is the comment, “I take it when I eat a high-carbohydrate meal.” In other words, these products are shifting from everyday staples to “insurance” used strategically on days when someone expects to overeat. This refers only to usage situations; these products are foods, not medicines.
Foodology’s “Coleology Cutting Jelly” (23,900 won for 10 pieces), which ranks No. 5, follows the same trend. Jelly and drinks are replacing tablets. The format is changing.

The No. 1 product wasn’t a supplement with special ingredients or a luxury supplement. It was an affordable, delicious, and sustainable shake costing 3,900 won. That’s Korea’s answer today. The consumer perspective of choosing “something you can stick with” over “something that works” created this TOP 20.
