Jung Kwan Jang · red ginseng since 1899
Which stops are on your day?
It isn't the plate of rice that wipes out your afternoon. It's the sugar spike after it.
Sound familiar?
- 10:30 · Kopi to get to lunch
- 12:30 · Rice or noodles at every meal
- 15:00 · The crash, right on time
- 20:30 · Full, but still craving sweets
- The waistline creeping up
Three or more? This isn't a willpower problem. Your blood sugar after each meal is running your day, and you can change that from your very next meal.
Pillar: after-meal sugar
GL Pro CoreAfter-meal sugar
One bottle after lunch, and no sleepy, sugar-hungry afternoon
- Steadier sugar after meals
- Supports insulin sensitivity
- More energy in the afternoon
- Fewer sweet cravings
When your blood sugar shoots up after a meal, it crashes soon after, and you feel sleepy and want something sweet. Red ginseng's ginsenosides, with banaba leaf and the bitter gourd you know from home cooking, help keep after-meal sugar on a gentler curve. A steadier afternoon means fewer cravings.
Cheong Kwan Jang only uses Korean red ginseng grown for a full 6 years, and the KGC05pg ingredient is recognised by Korea's MFDS for blood sugar. 23 mg ginsenosides a bottle, 0 g sugar, 5 kcal. Shake and drink; no fridge needed.
The real problem
Cutting a spoonful of rice won't last. GL Pro Core handles what happens after you eat.
Nobody gives up nasi for good, and GL Pro Core won't ask you to. Have your meal, then drink one bottle. The red ginseng, bitter melon and banaba leaf deal with the blood sugar that meal brings, and your afternoon stays level.

Frequently asked questions
Results and how it works
Does GL Pro Core really control blood sugar?
Yes, that's its job. The KGC05pg red ginseng inside is recognised by Korea's MFDS for blood sugar and went through a 12-week human study. Alongside it, bitter melon helps hold blood sugar steady after you eat, and banaba leaf improves insulin sensitivity. It works best with balanced meals and exercise. It isn't a medicine, so if you're on blood-sugar medicine, talk to your doctor before starting.
When will I see results?
It varies. In weeks 1–2, the after-lunch slump comes less often and afternoon energy evens out. In weeks 3–4, sweet cravings ease; over 85% of Korean users reported a clear change within 4 weeks. By weeks 8–12, post-meal blood sugar is steadier and you start seeing it on the scale and your belt.
Why after a meal?
It is there to deal with the blood sugar that meal brings. Drink it once you've eaten and the red ginseng, bitter melon and banaba leaf work alongside the food; doing it after lunch keeps the afternoon level.
Can I take it with Kuro Shuga?
Yes. Chew Kuro Shuga before lunch and dinner, and drink GL Pro Core once a day after a meal.
How to take it
How do I take it, and when is best?
One bottle daily, after you eat. Shake it, drink all 25 ml in one go once it's open. Taking it after lunch keeps the afternoon level. Nothing to mix, no need to chill.
Does it contain sugar?
The box says 0 g sugars and 5 kcal per bottle. The sweetness comes from stevia and allulose (3 g per bottle), with a light fruity taste.
Is the sediment at the bottom normal?
Yes. Red ginseng drinks can settle a little at the bottom, and it's harmless; just shake before you drink. Keep it somewhere cool and dry, out of direct sun.
Will red ginseng make me feel heaty?
For most people it sits well. Red ginseng is fresh ginseng that has been steamed, then dried. Jung Kwan Jang calls it warming, not heaty, and you may notice a gentle warmth as your body picks up pace.
Safety
Who should check with a doctor first?
It's made for adults aged 18 and over. Pregnant or breastfeeding, on blood-sugar medicine or blood thinners, or living with a kidney condition? See your doctor before you start. Skip it if any ingredient gives you an allergy.
Can it replace my blood sugar medicine?
No. GL Pro Core is not a medicine and does not replace prescribed medication. If you take medicine, ask your doctor before drinking it, and never stop your medicine on your own.
Does it contain animal ingredients? Is it Halal?
No animal-derived ingredients and non-GMO, according to Jung Kwan Jang. Our sources show no Halal certification for it; if you need Halal, ask your advisor first or check the pack.
I have food allergies. Can I take it?
The brand states it is free from gluten, dairy, soy, eggs, fish, shellfish and peanuts. Check the ingredient list first; do not take it if you are allergic to any ingredient, and stop if any reaction occurs.
Buying and authenticity
Is Jung Kwan Jang GL Pro Core Red Ginseng Shot 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 it genuine? How can I check?
Yes, genuine and sealed: original Jung Kwan Jang stock made in Daejeon, Korea by Korea Ginseng Corp. Every box carries barcode 8800255101253 on the back, so you can check it when it arrives.
Why do some sellers charge much less?
Take care. A price far under normal can mean old stock, a repack or a fake. Something you drink daily should come in a box you can verify.
Who makes GL Pro Core?
Korea Ginseng Corp., under its red ginseng brand Jung Kwan Jang (also spelled Cheong Kwan Jang, 正官庄). The company has been making red ginseng since 1899, and GL Pro Core comes out of its Daejeon facility in Korea.
How long does one box last, and how many should I buy?
21 bottles, 21 days at one a day. One box to try it; four boxes for the whole 12 weeks (recommended), S$6.01 a day; six boxes for the long run at the lowest price a box, S$5.86 a day.
How do I order, and what does delivery cost?
Pick your boxes and tap order. Messenger opens, your advisor confirms the address and payment, and your order ships free.

Which stops are on your day?
Count how many of these happen most days.Learn more
10:30 · Kopi to get to lunch
Kopi, teh or a sweet drink almost every day. Without it, you don't make it to noon.
12:30 · Rice or noodles at every meal
Economy rice, char kway teow, bread. Eating out and tapau, the carbs are unavoidable.
15:00 · The crash, right on time
Heavy eyes and a foggy head by 2 or 3pm. You're nodding off in meetings.
20:30 · Full, but still craving sweets
A piece of kuih, a slice of cake, a packet of biscuits. Skip it and something feels missing.
The waistline creeping up
You don't eat that much, yet the scale and your waistline climb a little every year.
Three or more? This isn't a willpower problem. Your blood sugar after each meal is running your day, and you can change that from your very next meal.Learn more
The real problem
It isn't the plate of rice that wipes out your afternoon. It's the sugar spike after it.
Rice, noodles, bread and sweet kopi hit your bloodstream fast and your blood sugar shoots up. Your body rushes to bring it down and often overshoots. Spike, then dip: that's your 3pm slump, and the cravings that won't stop at night.Learn more
It's a roller coaster
The higher the spike, the deeper the dip. Your energy follows your blood sugar, so your afternoon swings between alert and foggy.
It's a craving switch
When blood sugar dips, your body calls for sugar. Craving sweets on a full stomach isn't greed; the signal has been scrambled.
It repeats every day
Morning kopi, a plate of rice at lunch, dessert in the afternoon, snacks at night. Several spikes a day, every day.
It won't stop on its own
As long as you eat out and eat rice, the cycle comes back every day. What needs handling is what happens after each meal.
Sugar spike after a meal
Balanced blood sugar after a meal
Sticky sugar crystals crowd the vessel, blood cells sluggish and jammed
A clear vessel, blood flowing smoothly, sugar in balance
Cutting a spoonful of rice won't last. GL Pro Core handles what happens after you eat.

Sound familiar?
Why what you tried didn't stick
Cutting rice and noodles
Fine for a meal or two. Eating out, hawker centres and tapau make rice and noodles unavoidable. The issue isn't the rice; it's what your blood sugar does afterwards.
Kopi and sweet drinks to get through the afternoon
They carry you for a while, then the sugar and caffeine wear off, you dip again, and the night-time cravings get worse.
Home-made bitter melon juice or tea
The right idea, but bitter and fiddly, so it's hard to keep up every day. GL Pro Core puts bitter melon extract into a fruit-flavoured 25 ml shot.
Any ginseng drink
A quick lift doesn't look after blood sugar. GL Pro Core is built on KGC05pg, a red ginseng that Korea's MFDS recognises for blood sugar, with bitter melon and banaba leaf alongside.
The mechanism
The 3pm slump, after-meal cravings and a growing waistline are often one cycle
After every meal, the same three steps play out:Learn more
Blood sugar spikes after the meal
The sugar in rice, noodles, bread and sweet drinks reaches your blood fast, and your blood sugar shoots up.
It crashes, and so does your afternoon
Your body rushes to bring it down and often overshoots. Your energy drops with it, and by 2 or 3pm you're fading.
The dip sends you for sugar, and it spikes again
Low blood sugar makes your body ask for more. You reach for kuih or a sweet drink, and the next spike begins.
GL Pro Core steps in at the start of the cycle
GL Pro Core steps in at the start of the cycle
A 25 ml shot once you've eaten: KGC05pg 6-year red ginseng, bitter melon and banaba leaf handle the blood sugar that meal brings. Steady blood sugar → no afternoon crash → fewer cravings → weight is easier to manage. Rice stays on the plate, and there's nothing to mix.
