Is ZENSO Safe and Legit in Singapore? Ingredients, Side Effects and the Scam Question

The short answer

No supplement is “safe for everyone”, and anyone who says so is selling something. What can be checked is what is in the box, how it is made and tested, who should talk to a doctor first, and whether the box in your hand is genuine. This guide covers those four things for the ZENSO range sold in Singapore.

ZENSO is a line of food supplements made by Wellous. It is not a medicine, and it is not a restaurant or a clinic. The Health Sciences Authority (HSA) does not assess supplements for efficacy before they are sold, so the checks below matter.

What is in it

The five “Kuro” formulas each do one job. Kuro Daitto is a meal shake built around Slimaluma® (330mg per serving). Kuro Shuga is a chewable with CQR-300® (150mg) and a sugar-blocking combination. Kuro Oiru uses Morosil® (400mg) and African Mango Extract®. Kuro Mizu is a drink sachet with CactiNea™ (1,000mg). KURO KOSEN is a metabolism-focused drink featuring prune essence, black tea and wheat-derived fibre.

The set names tell you how many of the five you get. Lite has three, Advance has four, and Pro has all five (with two boxes of Kuro Kosen). GLPro is a separate six-box system built around the GLPro Core concentrate. The Pro page lists a shaker, body-composition scale, tape and the Zenso app as free with the order.

The brand states that the line contains no stimulants and no hormones. The mechanisms it describes are enzymatic, nutritional and botanical. Check the printed label on your box for the full ingredient list, because that is the authoritative version.

How it is made and tested

The manufacturer states that the range is made in GMP-certified facilities and that each batch is third-party tested. The Pro page also states that the product was screened by SGS for 365 drug substances, including anti-obesity drugs. These are manufacturer statements; ask for the certificate of analysis by batch number if you want to see the paperwork, as described in our guide to reading a certificate of analysis.

Every genuine box carries a QR code. Scanning it is the quickest way to confirm that the batch is real.

Side effects: what to expect and who should check first

Supplements that affect appetite and fluid balance can affect different people differently, and a fibre product can change digestion for some people. If anything feels wrong, stop and speak to a doctor or pharmacist.

Speak to your doctor before starting if you are pregnant or breastfeeding, if you take prescription medication, or if you manage a medical condition. This applies especially if you are on semaglutide or any other GLP-1 medication: ZENSO is not a substitute for, or an add-on to, that treatment unless your doctor agrees.

Check the label for allergens and for who each product is intended for before you use it.

The scam question

People search “ZENSO scam” because two real problems exist. The first is lookalike listings: searching ZENSO in Singapore can surface a restaurant with the same name, and marketplace sellers can list products with similar names. The second is counterfeit or resold stock.

The practical protection is simple. Buy from a seller who publishes prices in Singapore dollars, scan the QR code on arrival, and treat a missing, scratched or already-claimed code as a reason to stop and contact the seller. Our verification page explains each case. Orders placed on this official store carry a 30-day money-back guarantee; marketplace listings are third-party sellers and are not covered by it.

Be wary of any seller who promises a specific number of kilos. The product page itself declines to give one, and we agree with that: results vary with diet, sleep, age and starting point.

Which ZENSO set, and what it costs

ZENSO Lite is S$510, Advance is S$735, Pro is S$930 and GLPro is S$750, all for a 30-day set. If you are unsure, start by reading the comparison of Lite, Advance, Pro and GLPro, or message the team and ask which set fits your routine.

The bottom line

ZENSO is a legitimate product line when you buy genuine stock, and the sensible way to treat any supplement is to read the label, check the batch, and talk to your doctor if you have a condition or take medication. It is not a medicine and it does not promise a result.
