Description
New Biofermin S — Japanese Designated Quasi-Drug with Three Human-Derived Lactic Acid Bacteria, 540 Tablets
Overview
New Biofermin S is Taisho's 整腸剤 — a bowel-regulating preparation that has been on Japanese shelves for generations. It is a 指定医薬部外品, a designated quasi-drug, not a food supplement, and it has an approved list of exactly four purposes: regulating bowel movements, soft stools, constipation, and abdominal bloating. This page states those four and stops there.
What makes it different from a yoghurt-derived probiotic is that all three organisms are human-derived (ヒト由来), which is why Taisho claims good adhesion in the human gut. The tablets are chewable, neutral-tasting and need no water. See the rest of our Japanese digestive and wellness range.
This product is a Japanese designated quasi-drug (指定医薬部外品): a regulated tier between a food and a medicine. It carries declared active ingredients and an officially approved list of purposes, and it may not claim anything beyond that list. Where this page states what the product is for, it states the approved purposes and nothing wider.

Who Is This For?
- Anyone from age five, with the tablet count stepped by age band — this is one of the few Japanese preparations of its kind dosed for children as well as adults
- People whose bowel habit swings between loose and constipated, which is what 整腸 means: regulating in both directions rather than pushing one way
- People who feel bloated after meals — abdominal bloating is one of the four approved purposes, not an incidental benefit
- Anyone who wants a lactic acid bacteria preparation without dairy, since all three organisms here are human-derived
- Not for: children under five, and not as a treatment for food poisoning, persistent diarrhoea or any diagnosed bowel condition — those need a doctor, not a 整腸剤
How to Use
- Adults and children 15 and over: 3 tablets per dose.
- Children 11 to 14: 2 tablets per dose. Children 5 to 10: 1 tablet per dose. Under 5: do not give.
- Take the dose three times a day, after meals.
- Chew or suck the tablets — they are designed for it, they taste neutral and they need no water.
- Give it time. A bowel-regulating preparation works by shifting the balance of gut flora, so judge it over weeks rather than days; if there is no change, or symptoms worsen, see a doctor.
Frequency: Three times daily after meals. Adults 9 tablets a day in total.
Full Ingredients
Active ingredients per adult daily dose of 9 tablets:
- Bifidobacterium powder (Bifidobacterium bifidum G9-1) — 18 mg
- Faecalis bacteria powder (Streptococcus faecalis 129 B 10) — 18 mg
- Acidophilus bacteria powder (Lactobacillus acidophilus KS-13) — 18 mg
All three are human-derived. Our previous listing named the first as "Bifidobacterium P 9-1" (the strain is G9-1), dropped the organism name from the second, and called the third "acidophilin", which is a different substance altogether. All three are corrected here.
Excipients: corn starch, lactose hydrate, precipitated calcium carbonate, malt sugar powder, sucrose, talc, magnesium stearate. Contains lactose — relevant if you avoid it.
Composition and specification as declared by Taisho Pharmaceutical. The complete declaration is printed on the pack; where a figure is not published by the maker, this page says so rather than filling the gap.
Cautions
- Do not give to children under five years of age.
- This is not a treatment for food poisoning. Our previous listing said it was. Food poisoning needs fluids and, often, a doctor — not a bowel-regulating preparation
- Diarrhoea that is severe, bloody, or lasts more than a few days needs medical attention, as does diarrhoea with fever. Do not manage it with this product alone
- Contains lactose and is taken nine tablets a day at the adult dose — worth knowing if you are lactose intolerant
- Stop and consult a doctor or pharmacist if symptoms do not improve, or if they worsen while taking it
- If you are taking antibiotics, ask your doctor or pharmacist about timing — antibiotics act on bacteria, including these
- Not contraindicated in pregnancy or breastfeeding, but tell your own doctor or midwife what you are taking
- Store in a cool, dry place away from direct sunlight, and close the pack after use
- Do not transfer the tablets to another container
- Keep out of reach of children
Package Contents
One bottle of 540 chewable tablets in its printed carton, with the Japanese package insert. At the adult dose of nine tablets a day this is about a 60-day course; for a five- to ten-year-old at three a day it lasts far longer.

FAQ
Is this a probiotic supplement?
It is a designated quasi-drug (指定医薬部外品), which sits above a food supplement and below a medicine in Japanese regulation. Practically, that means the three organisms are declared actives with stated amounts and the product has an approved purpose list — rather than a food making general gut-health claims.
Our previous page said it helps with food poisoning. Does it?
No, and we should not have said so. The approved purposes are exactly four: regulating bowel movements, soft stools, constipation and abdominal bloating. Food poisoning is not among them, and treating it with a bowel-regulating preparation instead of seeking care is the wrong move. That claim has been removed.
What does human-derived mean, and does it matter?
All three strains were isolated from humans rather than from dairy or plant fermentation. Taisho's stated reason for it is adhesion — bacteria adapted to the human gut are expected to settle better there. It also means this is a lactic acid bacteria preparation that does not come from milk, though note the tablets do contain lactose as an excipient.
Can children take it?
From five years, at one tablet three times a day; 11 to 14 take two; 15 and over take three. Under five, do not give it. The tablets are chewable and neutral-tasting, which is what makes the child dosing practical.
How long does one bottle last?
540 tablets at the adult rate of nine a day is about 60 days, which matches the pack's stated 約60日分. If more than one person in the house is taking it, divide accordingly.
