After That Lunchtime Question, I Went Through Every Rumor About Japanese Fuji Supplements One by One

My lunchbox was still unopened when Ah-Hong from the next department tossed out a question: "Have you guys ever heard of Japanese Fuji supplements?" He said it casually, like he was asking about the weather. Old Chen, sitting across from me, put down his chopsticks and said that in all his years in sales, clients had occasionally mentioned this kind of thing, but he never figured out whether it was medicine or food. Little Tsai, who had just finished his military service, jumped in right away, saying he'd seen lots of people asking about it online, and someone had even put together a list, making it sound like you'd regret not buying it. Three people, three ages, three different takes—after listening, I just felt confused, so I decided to go home and break it down myself.

The first thing to unpack was: "Is this medicine?" Old Chen was the most conservative, saying that if anyone talks about it in terms of your body, it should be treated as medicine. Little Tsai thought that if the packaging says health supplement, it's just food, nothing to worry about. I went home and looked through several sources before realizing both views were too hasty. The same name can be classified differently in different countries—sometimes as a prescription drug, sometimes just as food or a supplement, and even the same ingredient can be positioned differently depending on the sales channel. In other words, just relying on someone saying "it's medicine" or "it's food" doesn't answer anything.

The second thing to unpack was: "Why is everyone talking about it?" Ah-Hong painted the most vivid picture, saying it got popular because someone described it as really effective, and word spread from person to person until it became common knowledge. I thought about it later, and this is actually the common path for all hot health topics: first there's demand, then a bunch of copycat claims, and finally an atmosphere. Atmosphere isn't fact. What you can actually verify is very little—mostly packaging labels, import sources, the legality of the sales channel, and which category local regulations put it in. As for those very specific effects, I couldn't find any public data that matched, so I just noted them down without treating them as conclusions.

The third thing to unpack was: "Where should I actually ask?" Little Tsai said he reads others' experiences in communities, and Old Chen said he asks a pharmacy he knows. My approach was to write down the questions and split them into two piles: one pile was "What category is this, and where does it come from?" and the other was "Is my current situation suitable for trying it?" The first pile I could look up myself; the second pile I wasn't capable of judging, and I shouldn't rely on netizens' shares to judge it. Later, I took that piece of paper to a nearby pharmacy to ask. The pharmacist didn't draw any conclusions for me, but reminded me to list everything I'm currently taking, including vitamins and other supplements, on a single sheet, and then discuss it with a professional. That sounds basic, but it was the most valuable thing I learned that day.

The fourth thing to unpack was: "The search itself." I noticed many discussion threads start with the same kind of question—for example, someone directly asks about Japanese Fuji supplements on a forum, and then all sorts of contradictory answers start appearing. That kind of question isn't wrong; the mistake is treating search results as answers. My judgment steps are: first, check if the source has a byline and states its basis; second, see whether it's stating regulations or relaying someone else's experience; and finally, check if it's selling something. If the last one is true, I halve the weight of the whole piece. This isn't to say sellers are necessarily untrustworthy, but I'm not capable of telling, so I'd rather step back first.

The fifth thing to unpack was: "Price and convenience." Ah-Hong said buying online is fastest, and some say it's much cheaper. I later understood that cheap and convenient aren't problems in themselves; the problem is that they skip the verification steps entirely. For something shipped from abroad, who handled it along the way, what the storage conditions were, whether the packaging has labels in the local language—none of that can be seen at the moment of delivery. Old Chen's experience is that he'd rather walk a few extra steps, pick up the item in person to see it clearly, and ask questions on the spot. I don't have his salesperson patience, but at least I learned one thing: when you compare "fast" with "clear," you usually find it's hard to get both at once.

The sixth thing to unpack was: "Can I decide about my body on my own?" Little Tsai said he's young and thinks you just try it and see. I can't answer for him, and I don't intend to answer for anyone. What I can say is that when a topic involves your body, you shouldn't use "someone said it worked" as a basis. The real line is: can I clearly state what I'm currently taking, whether I have other conditions, and what category this thing belongs to? If I can't say it clearly, then it's not a choice—it's just gambling. Take the list to a doctor or pharmacist and let them judge; no one can do that step for you.

That one lunchtime sentence ended up as a piece of paper on my desk. I divided the claims I heard into three columns: what can be verified, what can't be verified but many people say, and what needs a professional to answer. The first column was the smallest but most useful; the second was the largest, but I learned not to treat it as an answer; the third I kept for the next checkup or pharmacy visit. Ah-Hong later asked how my research was going, and I just replied: first figure out what you're actually asking, then decide whether to go further. It's not a profound conclusion, but at least it's better than a table of people each saying their own thing and then spreading the same sentence again the next day.
