Why people start
Kopi with condensed milk. Char kway teow. A bowl of rice, then another. Singapore eats brilliantly and constantly — and most of us feel it about ninety minutes later, face-down in a spreadsheet.
Most people respond to that by resolving to fix everything at once. Fewer carbs, more steps, earlier nights.
GLPro™ Core is the opposite of that. One 25 ml bottle, once a day, after a meal. It takes four seconds. It doesn't ask you to give up anything. It's the smallest possible thing you can add to a routine you already have — which is exactly why people are still doing it in month three.
Four seconds
A 25 ml bottle is about the size of your thumb. Shake it, drink it, put it down. There's no measuring, no mixing, no waiting for it to dissolve, and nothing to wash up.
That sounds like a trivial detail. It's the entire reason people finish the box — and finishing the box is the only thing that matters.
What's inside
No proprietary blends, no list of twenty ingredients at trace doses.
Jung Kwan Jang's own standardised red ginseng extract, developed in-house and recognised by Korea's Ministry of Food and Drug Safety as an individually-approved functional ingredient in 2024.
Ginseng reaches full maturity in its sixth year — that's when the root has its most complete structure and its richest concentration of active ginsenosides. GLPro Core uses only fully matured 6-year roots.
Lagerstroemia speciosa, long used across Southeast Asia and the Philippines. Its studied constituent is corosolic acid.
Momordica charantia — the bitter gourd your grandmother already believed in, here as a concentrated extract rather than a plate of it.
Who makes it
The flagship brand of Korea Ginseng Corporation, with heritage tracing to 1899. Euromonitor has ranked it the world's No.1 ginseng brand for 12 consecutive years, with a 44.3% global share.
KGC has published over 290 scholarly articles internationally, holds 200 technical patents, and developed 15 of its own ginseng varieties with registered plant variety rights.
In March 2025 the American Botanical Council presented KGC with its Varro E. Tyler Award, recognising sustained commercial investment in phytomedicinal research. An independent, US-based honour — not an industry self-award.
The KGC05pg red ginseng extract was evaluated in a 12-week randomised, double-blind, placebo-controlled study of 98 adults, published in the peer-reviewed journal Medicine in 2024 (Jeong et al., 103(52):e41130). The study reported no treatment-emergent adverse events and no serious adverse events in either group.
We describe the study's design and safety findings only. The research was conducted and funded by the manufacturer, results in a single study do not guarantee any individual outcome, and this product is not intended to diagnose, treat, cure or prevent any disease.
How it works in real life
Give the bottle a shake before opening. Natural plant sediment is normal and expected.
One 25 ml bottle a day, after eating. Many people pair it with lunch so it becomes automatic. Finish the bottle once opened.
The published study ran 12 weeks. That's the honest timeframe, and it's why we lead with the four-box programme rather than a single box.
Each box holds 21 bottles — a three-week supply. Four boxes covers the full 12 weeks.
A lot of our orders
He won't change how he eats. You've tried. Everyone's tried. There's a version of this conversation that happens at every family dinner and it never goes anywhere.
But he'll drink one small bottle after lunch — because it takes four seconds, it doesn't taste like medicine, and it doesn't require him to admit anything.
Sometimes doing one small thing is the whole point.

Not because it's the bigger box, but because it's the length the research actually ran. Three weeks tells you whether you like the taste. Twelve weeks is the commitment the product was designed around.
Prices in Singapore dollars, inclusive of GST. Struck-through prices are the single-box price multiplied by quantity. Sealed boxes can be returned within 14 days.

Before you order
We would rather lose the sale than have you take something you shouldn't. Please check with your doctor before using GLPro™ Core if any of these apply:
Not for children. Do not use if you are allergic to any listed ingredient. Stop taking it and seek medical advice if you feel unwell. Never stop or change prescribed medication — this is a health supplement, not a medicine, and it does not replace medical care.
Questions
Light and fruity, not the heavy bitter ginseng tonic you may be bracing for. It's sweetened with allulose and stevia rather than syrup, which is how it stays at 0.3 g of sugar and six calories. Most people drink it straight from the bottle in one go. This matters more than it sounds — a supplement you dread drinking is one you stop drinking in week two.
One bottle a day, after a meal. Shake before opening and finish it once opened. The specific time of day matters less than doing it at the same time every day — pick a meal you never skip and attach it to that.
The published study ran for 12 weeks, and that's the timeframe we'd point you to. We'd rather tell you that upfront than sell you one box on the suggestion that three weeks will do something. If you want to try a single box first to see whether the taste and routine suit you, that's a perfectly sensible way to start.
Please ask your doctor or pharmacist first, particularly if you take medication for blood sugar or any anticoagulant. Red ginseng and bitter melon can both interact with those. Bring the box or this page to your appointment — the full ingredient list is on the carton. And whatever you do, don't stop or reduce a prescribed medication.
In the 12-week study of 98 adults, no treatment-emergent adverse events and no serious adverse events were reported in either group. That said, no supplement is right for everyone — the most commonly reported effect with ginseng generally is difficulty sleeping, which is one reason we suggest taking it during the day. If you feel unwell after taking it, stop and see a doctor.
No, and we won't pretend otherwise. Those are prescription medicines that act directly on a receptor, prescribed and monitored by a doctor. GLPro™ Core is a health supplement made from red ginseng and two botanicals. Different category, different regulation, different thing entirely. If you need a medicine, you need a doctor.
Health supplements in Singapore are not subject to pre-market approval or licensing by the Health Sciences Authority. Sellers are responsible for ensuring their products are safe and comply with HSA's requirements. GLPro™ Core is manufactured in Korea by Korea Ginseng Corporation under GMP, HACCP and ISO 9001 standards.
Orders ship from Singapore and typically arrive in one to three working days. Delivery is free on two boxes or more. Sealed, unopened boxes can be returned within 14 days of delivery for a refund. If a box arrives damaged, message us on WhatsApp with a photo and we'll replace it.
Please contact us before ordering if halal certification is a requirement for you — we'd rather confirm the current certification status for your specific batch than give you a general answer.
Korean red ginseng from a company that has been studying it since 1899 — in the smallest, easiest format they've ever put it in.
