What is the Luckin Coffee lactic acid bacteria Americano?

Luckin Coffee has launched a national limited-edition Lactic Acid Bacteria Americano in collaboration with the internet cat brand EverydayOneCat, also called Silly Cat. The drink mixes lactic acid bacteria, caffeine and ice, and first appeared as a Shanghai-only item in October before rolling out nationwide. Online discussion has centered less on flavor and more on the digestive effect, with some users calling it Poop Water.

Each order now ships with three packs of collaboration-themed pocket tissues, up from one pack with last year's Prune Americano. That detail fueled jokes, since an American coffee brand offering tissues alongside a probiotic drink invites a certain reading. On social platforms, some buyers report immediate results and others say they felt nothing, so individual body differences remain the main talking point.

Luckin Coffee recently collaborated with the popular internet IP "EverydayOneCat" (Chinese name: Shadiao Cat) to launch two limited-edition drinks: Lactic Acid Bacteria Americano and Lactic Acid Bacteria Iced Tea. The Lactic Acid Bacteria Americano briefly appeared as a Shanghai regional limited edition last October, and now that it's available nationwide, fans are rushing to buy it. However, consumers' focus isn't on the drink's flavor, but rather its laxative effect—the combination of lactic acid bacteria, caffeine, and ice has been jokingly dubbed "Poop Water" by netizens. This time, Luckin includes 3 packs of collaborative-themed pocket tissues with each order, compared to just 1 pack with last year's Prune Americano, which has sparked even more imagination among netizens. On social platforms, some report "instant results," while others say they felt nothing at all, making individual body differences the focus of discussion. This article will review the background of the new product launch, consumer testing feedback, and various perspectives.

Recently, Luckin collaborated with an extremely popular internet cat "EverydayOneCat" (Chinese name: Shadiao Cat) to launch limited-edition drinks: Lactic Acid Bacteria Americano and Lactic Acid Bacteria Iced Tea.

In fact, the Lactic Acid Bacteria Americano briefly appeared as a regional limited-edition iced drink in Shanghai stores last October, attracting many local users to visit and try it. Now this "fleeting" drink has launched nationwide along with the collaboration, and fans who couldn't taste it last year immediately placed orders.

However, after the new product launched, what the public cared about wasn't the taste of the Lactic Acid Bacteria Americano itself, but rather whether this drink could solve their constipation troubles.

In the public's impression, one of the main benefits of lactic acid bacteria is promoting intestinal peristalsis, and caffeine can produce similar effects, plus the ice cubes that stimulate sensitive stomachs—in the eyes of onlooking netizens, Luckin's Lactic Acid Bacteria Americano is a "Poop Water" stacked with buffs.

Precisely because of users' first impression of the Lactic Acid Bacteria Americano, Luckin thoughtfully included specially packaged pocket tissues in this collaboration's merchandise. If consumers order through the mini-program, each Lactic Acid Bacteria drink comes with 3 packs of collaborative pocket tissues. Seeing the official brand so thoughtfully provide 3 packs of tissues, many couldn't help but feel somewhat amazed at the new product's power.

You should know that when the Prune Americano launched last year, Luckin only included 1 pack of pocket tissues per drink. Now, the brand has given 3 packs in a row, which inevitably makes netizens speculate, curious whether this new product's power is even greater than before.

According to feedback from those who tried it, the new product's laxative effect can be described as instant: "Giving three packs of tissues is right! One pack is simply not enough!" "Very laxative! But not to the point of stomach pain," "Drank it at 9, by 9:50 already had explosive diarrhea." Some compared it to the Prune Americano, believing the Lactic Acid Bacteria Americano's effect is more obvious: "Prune had no effect on me, but this one I drank in the morning and have already gone to the toilet three times."

In the "drinking reviews" continuously posted on social platforms, many admitted that shortly after drinking the Lactic Acid Bacteria Americano, they transformed into "super soakers," using personal experiences and photos to prove "drinking it really makes you poo." However, some users who took on the challenge after hearing the Lactic Acid Bacteria Americano's reputation as a "laxative miracle" expressed disappointment after trying it, saying they didn't immediately grab tissues and run to the bathroom like others, and had no reaction all day.

In response, some believe that although from the ingredient perspective, the Lactic Acid Bacteria Americano contains lactic acid bacteria and caffeine that promote intestinal peristalsis, due to differences in drinkers' constitutions, these ingredients exert different effects in different people's bodies. It's understandable that some users with iron stomachs didn't get the expected results after drinking it.

They stated that the Lactic Acid Bacteria Americano is essentially just a coffee drink, not a remedy for constipation, and frankly the public shouldn't hold too high expectations for it.
