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.
Bloating eases in month 1. The waist changes in months 2–3.

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, SGD 65 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 90-Day 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 hawker meal 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 hawker choices that won't bloat you.
Yes. Neither product contains laxatives or creates dependency. Spiro Plus is plant-based and Halal certified; Kuro Kosen is a low-calorie fibre drink with no added sugar.
Yes. Bloating and stubborn belly fat affect men and women alike, and the routine is the same for both.
You can, but if your belly grows through the day, the bloat layer is still there and fat-focused products won't touch it. If your signs are mostly bloating, Spiro Plus alone may be enough. Ask our healthcare consultant.
90 days if you mainly want a flatter belly and less bloating. 180 days if you've struggled for years, have yo-yo dieted, or want results to hold long term.
Both are plant-based and generally well tolerated, but please check with your doctor first if you take prescription medication, have a diagnosed condition, or are pregnant or breastfeeding.
Spiro Plus is Halal certified and 100% plant-based.
