Wellous · ZENSO fat blocker
It's not a lack of discipline. Your everyday meals are cooked in oil.
Oil isn't the enemy. Absorbing every drop of it is.
Sound familiar?
- Lunch is out, most days
- Fried food you can't quit
- Dinner is the heaviest meal
- No time to exercise
- Every festive season adds a notch
None of this is about willpower. The problem is the route the fat takes once it's inside you: absorbed, then stored.
Pillar: fat
Kuro OiruFat blocker + burn
From an oily meal, absorb a little less and burn a little more
- Blocks part of the fat
- Helps burn fat
- Speeds up fat metabolism
- Keeps cravings down
Chitosan works like a small sponge, catching some of the oil in your meal before your body absorbs it. L-carnitine carries fat into your cells' furnace to burn as energy. Morosil® and African mango help your body store less fat. If you eat out every day, this is the tablet for you.
Morosil® is a patented extract Bionap makes in Italy from Sicilian red oranges; two tablets give 400 mg, the daily amount used in the ingredient research. A second patented ingredient, IGOB131® African mango, joins it. Rose-milk flavour, chewed before meals.
The real problem
Don't give up fried food. Put a block in front of the fat.
Cutting out oily food doesn't survive a festive season, and skipping a meal makes the next one bigger. Kuro Oiru works differently: one tablet before you eat, chitosan binds fat from that meal, L-carnitine sends fat to be burned, and Morosil® and IGOB131® help your body store less. You keep eating. It keeps blocking.

Frequently asked questions
Results and how it works
Does Kuro Oiru really block fat?
Yes, that’s what it’s for. Chitosan latches on to fat in your meal before it can be absorbed. L-carnitine, Morosil® red orange and IGOB131® African mango then help you burn more fat and keep less of it. Pair it with sensible meals and some exercise for the best result.
When will I see results?
It depends on the person. Week 1: blocking starts with your first tablet, and oily meals feel less heavy. Weeks 2–4 (1 bottle): the scale begins to shift and clothes fit more loosely. Month 2 (2 bottles): your waist looks visibly slimmer, and fried food was never off the menu. Results vary from person to person.
How many kilos will I lose?
We don't give kilo numbers, because everyone starts from a different place, diet and activity level. Track your own starting point with a tape measure and a scale, and your advisor will review the changes with you.
Do I still need to watch my diet and exercise?
You can keep the food you love. Sensible portions and some exercise will still give you better results. A few walks a week is a lot better than zero.
What is the 400 mg Morosil® study?
Researchers gave adults 400 mg a day of Morosil® red orange extract and tracked body weight and waistline, alongside a balanced diet and daily walking. That research was on the ingredient, not on Kuro Oiru. Two Kuro Oiru tablets a day add up to the same 400 mg.
How to take it
How do I take it?
Two a day: one tablet half an hour before lunch and another half an hour before dinner. Just chew. It tastes of rose milk and needs no water.
Does it have sugar?
Per tablet, the label lists 0 g sugars, 0 g fat and 4 kcal. The sweetness comes from isomalt and sucralose.
Can I combine it with Kuro Daitto, Kuro Mizu or Kuro Shuga?
Yes, that is the ZENSO routine: Kuro Mizu on waking, Kuro Daitto at breakfast, and Kuro Oiru and Kuro Shuga chewed before lunch and dinner.
What if I miss a tablet?
No problem. Chew one before your next meal as usual; don't double up. What matters is the steady two-meals-a-day rhythm.
Safety
I'm allergic to shellfish. Can I take it?
No. The chitosan in Kuro Oiru is made from crustacean shells. If you’re allergic to shellfish or crustaceans, don’t take it.
Who should check with a doctor first?
Anyone pregnant, breastfeeding, on medication or managing a long-term condition should ask a doctor or pharmacist first. Not for under-18s.
Why is there no KKM MAL number?
Kuro Oiru is a food (a chewable tablet), not a medicine. MAL numbers are given to medicines and certain supplements, and NPRA (Ministry of Health Malaysia) classifies Kuro Oiru as food. SGS also tested it against 365 drugs and found none.
Is Kuro Oiru halal?
Yes. JAKIM has certified it halal. Separately, a JAKIM panel lab, Halvec Laboratories, tested it and found no porcine DNA.
Buying and authenticity
Is ZENSO Kuro Oiru Fat Blocker on Shopee, Lazada or Carousell genuine?
Often not. Wellous has issued a notice asking customers not to buy on Shopee, Lazada, Carousell or other third-party platforms. Many listings there are fake, plenty of people only find out after buying, and some sellers pretend to be us. Buy from an authorised distributor for the QR authenticity check, advisor follow-up and the 30-day money-back guarantee.
Is Kuro Oiru already in the ZENSO sets?
Yes. ZENSO Lite, Advance and Pro, the Keep Burn Set, ZENSO GLPro and the 7-Day Trial Pack all include Kuro Oiru. If you're already on one of these, you don't need to buy it separately; buy this bottle to target fat on its own, or to top up when the Oiru in your set runs out.
How long does a bottle last, and how many should I buy?
60 tablets, 30 days at 2 a day. One bottle to try it; two bottles (recommended) to reach month 2 of the timeline, when the waist starts to show, without reordering on day 30.
Why do some sellers charge much less?
Be wary of listings well under RM350 a bottle. Stock that cheap may be old, repackaged or fake. As an authorised distributor, we ship original, factory-sealed bottles, with an advisor to help you and a 30-day money-back guarantee.
How do I order and how fast is delivery?
Pick your supply and tap order. Messenger opens, your advisor confirms the address and payment, and your order ships free across Malaysia.
What if it doesn't work for me?
Take it properly for 30 days and don't feel a genuine difference? Message your advisor and you get 100% of what you paid back.

It's not a lack of discipline. Your everyday meals are cooked in oil.
Tick the ones that happen most weeks.Learn more
Lunch is out, most days
Nasi lemak, economy rice, mamak. You choose the dish. You never choose how much oil goes in the wok.
Fried food you can't quit
Fried chicken, goreng pisang, keropok. You said not today, then a colleague brings back a bag.
Dinner is the heaviest meal
Steamboat, BBQ, buffet, banana leaf. One table, more oil than the whole day before it.
No time to exercise
Work, traffic, home late. The fat goes in, and there is nowhere for it to be burned.
Every festive season adds a notch
Chinese New Year, Raya, Deepavali, Christmas. Each one leaves a little behind, and it never leaves.
None of this is about willpower. The problem is the route the fat takes once it's inside you: absorbed, then stored.Learn more
The real problem
Oil isn't the enemy. Absorbing every drop of it is.
An oily meal goes down, the fat is taken in, and your body's default move is to store it. Into the fat cells it goes, and the fat cells swell. You didn't eat more. You just left that route wide open, meal after meal.Learn more
Hawker oil is invisible
You see the fried chicken skin. You don't see the oil in the fried rice, the curry, the santan. Two meals out a day adds up to far more than you think.
Your body defaults to storing
Fat that's absorbed and not used gets sent to your fat cells. Over time, the belly and waist fill up first.
Fat with no way out
No time to exercise means the fat isn't burned. More in, less out, and the gap builds every day.
Festive fat doesn't leave on its own
What your body stores from one festive feast doesn't hand itself back. Over a year, it layers up.
Fat absorbed straight in
Fat caught and carried away
Oil droplets from fried food soak straight into swollen fat cells
Oil droplets caught in a soft fibre net and carried away; fat cells calm and smaller
Don't give up fried food. Put a block in front of the fat.
Don't give up fried food. Put a block in front of the fat.
Cutting out oily food doesn't survive a festive season, and skipping a meal makes the next one bigger. Kuro Oiru works differently: one tablet before you eat, chitosan binds fat from that meal, L-carnitine sends fat to be burned, and Morosil® and IGOB131® help your body store less. You keep eating. It keeps blocking.
Sound familiar?
Why what you tried didn't stick
Cutting out oily food
You last a week, then there's a wedding dinner or a festive open house. Willpower against Malaysian food loses every time.
Skipping a meal
Hungry by the afternoon, so dinner is bigger and oilier. The meal you saved comes back double.
Exercise alone
The oil comes in at two meals a day; the workouts come once or twice a week. Sweat can't keep up with the plate.
A cup of tea after
It feels lighter, but nothing was blocking the fat while it was in the meal. Wrong timing means always one step behind.
How it works
One tablet before the meal, three ways at the fat
Take one half an hour ahead of lunch, and again ahead of dinner, so it’s already there when the food arrives:Learn more
Block: bind fat from the meal
Chitosan, a fibre from crustacean shells, binds fat from the food you're about to eat before your body takes it in.
Burn: send fat to be used for energy
L-carnitine, an amino acid, helps shuttle fat into your cells' mitochondria to be burned for energy instead of kept.
Store less: fewer fats into fat cells
Morosil® (from Sicilian red oranges) and IGOB131® African mango help you store less fat. Garcinia and purple tea support how your body handles fat.
Base: 1,000-day black vinegar
Kurozu Japanese black vinegar, fermented for 1,000 days, brings amino acids, vitamins and organic acids that support your metabolism.
In ZENSO, Kuro Oiru runs the fat system
In ZENSO, Kuro Oiru runs the fat system
ZENSO starts from one idea: modern food throws five body systems off at once, and fixing just one lets the other four pull the weight back. Kuro Daitto closes the nutrition gap, Kuro Shuga redirects blood sugar, Kuro Oiru handles fat, Kuro Mizu tackles water retention and inflammation, and Kuro Kosen looks after the gut. Buy Kuro Oiru on its own to go straight at the fat you eat; to work on several systems at once, ZENSO Lite, Advance and Pro already include it.
