Korean red ginseng continues to gain scientific validation and commercial momentum in 2025. Recent clinical trials, regulatory milestones, and economic showcases confirm that this traditional herbal remedy is increasingly respected in modern health contexts. This post walks through the newest validated findings, what they mean for consumers & retailers, and how to choose the best products.
Major New Findings in 2025
Glycemic Control in Prediabetes
- A 12-week randomized, double-blind, placebo-controlled trial in prediabetic Korean adults (98 participants) used red ginseng extract powder (RGEP, “KGC05pg”) at 500 mg twice daily. The trial showed significant improvements in fasting blood glucose, post-meal glucose (30, 60, 90, 120 minutes in OGTT), HbA1c, insulin resistance (HOMA-IR), insulinogenic index, c-peptide, glucagon, adiponectin, and GLP-1 compared to placebo. Importantly, there were no serious adverse effects. Lippincott Journals+2NutraIngredients-Asia.com+2
- The red ginseng also reduced blood glucose area under the curve (AUC) for 0-120 min post‐meal by about 7.4%, and improved insulin resistance by roughly 22.8% in the intervention group vs control. NutraIngredients-Asia.com+1
Hormonal & Mechanism Insights
- GLP-1 (glucagon-like peptide 1) levels rose significantly in the red ginseng group vs placebo over 12 weeks. This is important, because GLP-1 is involved in blood sugar regulation and satiety. NutraIngredients-Asia.com+1
- Other hormonal parameters: adiponectin increased (promotes fat burning, metabolic health), glucagon decreased (lowering glucose raising hormone). NutraIngredients-Asia.com
Cellular & Preclinical Mechanisms
- A study in Foods (2024) showed that saponins from Korean Red Ginseng improved insulin signaling in liver cells via enhancing mitophagy (PINK1/Parkin pathway), reducing oxidative stress, boosting phosphorylation of IRS & AKT, and downregulating gluconeogenic enzymes. This suggests a deep cellular mechanism for improving insulin sensitivity. MDPI
Market Actions & Regulatory Recognition
- Following these clinical results, the Korea Ginseng Corporation (KGC / JungKwanJang) obtained approval from South Korea’s Ministry of Food and Drug Safety (MFDS / KFDA) for blood sugar control claims in functional health foods containing red ginseng.

- KGC has launched new product lines: GLPro Core (red ginseng + bitter melon) and GLPro Double-Cut (red ginseng + lemon balm) targeted at blood sugar management (with Double-Cut also claiming body fat reduction). These are positioned for both domestic and global markets. NutraIngredients-Asia.com
- KGC presented red ginseng at Growth Asia Summit 2025, highlighting its roles for healthy aging and blood sugar control to global health-nutrition companies. Korea Joongang Daily
Implications for Consumers & What to Watch For
What Consumers Should Know
- Dose & Duration Matter: In these studies, 500 mg twice daily over 12 weeks was used. Shorter durations or lower dosages may have weaker or inconsistent effects. Lippincott Journals+1
- Standardization is key: Products specifying extract type, ginsenoside content, and bioavailability are more trustworthy.
- Safety: The clinical trial reported no serious adverse events. However, prediabetic subjects without other major diseases participated; results may differ in people with comorbidities. Lippincott Journals
- Functional Claims Validated: With MFDS recognition, certain health claims are no longer just marketing—they have regulatory backing. But region matters: outside Korea, regulatory environment varies.
What Retailers & Brands Should Emphasize
- Highlight the clinical trial data (e.g. GLP-1 increase, HbA1c reduction, insulin resistance improvement).
- Emphasize regulatory approval (KFDA/MFDS) when marketing to build consumer trust.
- Product formats combining red ginseng with complementary ingredients (e.g. bitter melon, lemon balm) may broaden appeal (blood sugar + body fat support).
- International expansion: With approvals and trial data, brands may more easily enter non-Korean markets with usable science.
- Messaging for metabolic health, prevention (not just disease treatment). Many consumers are prediabetic or health-conscious rather than already diabetic.
Additional Health Context & Mechanisms
- Oxidative stress is a key driver of insulin resistance. The study on mitophagy suggests red ginseng helps remove damaged mitochondria via PINK1/Parkin, lowering ROS, improving mitochondrial health. MDPI
- Hormonal modulation (GLP-1, adiponectin, glucagon) suggests systemic effects beyond just “lower blood sugar”—includes satiety, fat distribution, glucose metabolism.
- Improvements in postprandial glucose (after meals) are especially relevant for daily life: they may reduce glucose spikes that contribute to long-term metabolic strain.
What to Look for When Choosing Red Ginseng Products
| Feature | What to Look For / Ask |
|---|---|
| Extract & Standardization | Does the label mention “red ginseng extract powder”, specify ginsenoside content, match what was used in clinical studies (e.g. KGC05pg)? |
| Regulatory Claims | Does the product have MFDS / KFDA functional claim for blood sugar control? Is it approved in your country? |
| Dosage / Serving Instructions | Similar dosage to trials: e.g. 500 mg x2 daily. If less, check evidence. |
| Combination Ingredients | Bitter melon, lemon balm, etc., are used in GLPro variants; they might enhance or assist metabolic effects. |
| Transparency & Safety | Lab testing, origin, absence of contaminants, side-effect information. |
| Format & Convenience | Tablets, sticks, extract powders—choose what works for daily adherence. |
Future Outlook & Questions to Watch
- Larger multicenter trials, across other populations (non-Korean, different age groups, people with metabolic disease).
- Longer term studies: beyond 12 weeks, to assess effects on diabetes incidence, complications, long-term safety.
- Mechanistic human studies clarifying GLP-1 pathways, hormonal changes, mitochondrial / cellular level effects.
- Product innovation: optimizing bioavailability, flavor, combinations.
- Regulatory shifts outside Korea: whether KFDA functional claims will help with approvals in other jurisdictions (US, Europe).
