Most belly products only fix one layer. This duo fixes both: Spiro Plus clears the bloat while you sleep, Kuro Kosen supports your metabolism while you're awake. No laxatives, no strict diet.

Sound familiar?
Your face gets slimmer. Your belly doesn't.
Arms toned, legs toned. Belly exactly the same.
Flat for one morning, after a night in the toilet. Back by lunch.
Heart racing, RM150 a month, and the jeans still don't close.
You're not failing.
You're fixing the wrong layer.
The real reason
Layer 1: the bloat you can feelAfter 30, your digestive enzymes drop. Half-digested food ferments into gas, so your belly is flat in the morning and looks 4 months pregnant by dinner.
Layer 2: the fat you can't pinchVisceral fat sits behind your abs, around your organs. As metabolism slows with age it holds on, and crunches or cutting rice barely touch it.
Fix only one layer and the other brings the belly back.
This isn't just fat under your skin.
Visceral fat is the fat you can't see in the mirror. It sits deep inside your belly, and it's what makes a belly hard, round and stubborn.
The fix: one routine, both layers
Kuro Kosen works by day, while you eat and move. Spiro Plus works at night, while your gut rests and digests.
1 sachet in 200 ml water, 30 min before a meal
3-year fermented Kyushu black vinegar, black tea extract and prune essence support your metabolism while you're active.
Chew 2 tablets before bed
17 digestive enzymes and dual spirulina break down the day's food overnight, so it digests instead of fermenting.
Spiro Plus clears the bloat. Kuro Kosen works on the layer underneath.
Together, they're a Complete Belly Reset System.
The first change isn't on the scale. It's your evenings. Dinner no longer leaves your stomach tight and hard, and you wake up feeling lighter than when you went to bed.
Now the deeper layer starts to move. Cravings quieten, the 3pm slump fades, and your belly stops growing through the day.
Flat in the morning, still flat after dinner. Your digestion runs on its own rhythm, and a heavy nasi lemak or mamak supper no longer undoes your progress.

Still deciding?
Because almost everything works on one layer. Detox tea flushes the bloat for a day; diets and fat burners work on fat while the gut stays backed up. The duo clears the bloat layer every night and supports metabolism every day.
No. There's no flushing. Spiro Plus helps you digest food properly so less of it ferments, and Kuro Kosen supports the metabolism layer that usually rebounds after diets.
No. Neither product contains laxatives. Most people simply find their mornings more regular.
Most people feel lighter within the first 1–2 weeks. A visibly flatter belly usually shows between weeks 4 and 12, depending on your starting point and consistency.
No strict diet. Eat normally and move a little; your healthcare consultant will suggest small tweaks that fit your routine, like mamak and hawker choices that won't bloat you.
Choose 90 days if your main problem is bloating and a belly that grows through the day. One full cycle (Clear, Burn, Hold) is usually enough to feel and see the difference.
Choose 180 days if you've struggled with your belly for years, have tried diets that always bounce back, or want the results to stay. Bloating eases first; visceral fat and a slow metabolism take longer to shift, and the second 90 days is where most people lock in their new normal. It's also the lowest price per day (RM13.22 vs RM13.77), with 2 free Kosen boxes, 24/7 priority support and the VIP Health Event Pass.
Don't want to pay in one go? You can split it into instalments with Atome, GrabPayLater, ShopeePayLater or a credit card instalment plan (subject to the provider's approval). For example, spread over 6 months:
WhatsApp us at +60 18-310 9913 and we'll set up the instalment plan for you.
Because it isn't one product doing one job. You get two products that work on both layers of a stubborn belly, made with patented, branded ingredients most products don't use:
Every batch is made in GMP and HACCP facilities and SGS lab tested, with KKM and Halal (Spiro Plus) certification, and developed with our Medical Research & Advisory Board. No laxatives, no stimulants, no crash diets.
On the 90- or 180-day plan it works out to about RM13 a day, less than a mamak dinner. Many people already spend RM500+ a month on detox tea, fat burners, probiotics and fibre powders that each fix only one layer, and the belly stays.
Because those listings aren't from us. Wellous has officially announced that Spiro Plus and Kuro Kosen are sold only through authorised dealers and official websites like this one. Listings on Shopee, Lazada or TikTok Shop may be parallel imports, near-expiry or old stock kept in hot warehouses, or simply fake, and that's why the price is lower.
When you buy here, you get:
A cheaper box that's expired, fake or used without guidance isn't a saving. It's money spent on a belly that doesn't change.
No. Wellous has officially announced that Spiro Plus and Kuro Kosen are sold only through authorised dealers and official websites like this one. We don't sell on Shopee, Lazada, TikTok Shop or any other marketplace, so listings there are not genuine.
Every order ships from fresh stock, and every pack carries its own hologram QR code. Scan it and you'll see the production date and batch details. If anything looks or tastes off, WhatsApp us a photo straight away.
No. Dependency usually comes from laxatives and stimulants, and neither product contains them. Spiro Plus supplies digestive enzymes and greens that help your body break food down properly; Kuro Kosen is a low-calorie fibre drink. Your gut isn't being forced to work, so it doesn't "forget" how when you stop.
Most people complete a full 90- or 180-day reset, and many keep it in their daily routine afterwards simply because they like how they feel. Your healthcare consultant will help you plan what comes next based on your progress.
Both are suitable for daily, long-term use: Spiro Plus is plant-based and Halal certified; Kuro Kosen has no added sugar and no preservatives.
Other supplements: In most cases, yes. Spiro Plus and Kuro Kosen are food-based (enzymes, greens, fibre and fruit extracts) and are commonly taken alongside vitamins, fish oil or collagen.
Medication: Because Kuro Kosen is rich in fibre, take it at least 2 hours apart from your medication so it doesn't affect how your medicine is absorbed. If you're on prescription medication (for example for diabetes, blood pressure or blood thinning) or have a medical condition, please check with your doctor before starting.
Pregnant or breastfeeding? Please consult your doctor first.
Not sure? WhatsApp our healthcare consultant your current routine and we'll guide you.
Yes. Bloating and stubborn belly fat affect men and women alike, and the routine is the same for both.
Your gut is the root. If you only try to lose weight but your gut isn't clear, waste keeps building up and your body can't digest food or absorb nutrients properly. Then no matter how much, or how expensive, the product you take, it won't work as well.
That's why we pair them: Spiro Plus clears the gut, Kuro Kosen supports your metabolism. If you still prefer just one, WhatsApp our healthcare consultant and we'll advise what suits you.
Spiro Plus is Halal certified and 100% plant-based.
Please snap a photo of your parcel and products when they arrive. If anything isn't right (damaged, a change in taste, signs of oxidation, or you suspect it isn't genuine), WhatsApp us the photo and we'll replace it 1-to-1.
We don't refund based on personal results, because results build over the full programme and your consultant helps you adjust along the way.
You can pay securely by card at checkout. Prefer bank transfer, or instalments with Atome, GrabPayLater, ShopeePayLater or a credit card instalment plan? WhatsApp us at +60 18-310 9913 and our team will help you place your order. Over 6 months, the 180-day plan works out to about RM396.50 a month.
