DHM: Why China’s Vine Tea Extract Is the New Star of Functional Ingredients
In the rapidly expanding world of botanical extracts, one compound is generating serious buzz among formulators and brand owners: Vine tea extract Dihydromyricetin, better known as DHM. Derived from Ampelopsis grossedentata—a plant native to southwestern China and traditionally used as a medicinal tea—DHM has caught the attention of researchers and the health product industry for its multi-targeted biological activity. Chinese wholesale suppliers have become the global powerhouse for this ingredient, offering high-purity extracts and custom manufacturing that align with the needs of the nutraceutical, functional beverage, and supplement markets.

What Makes Dihydromyricetin Stand Out?
DHM is a flavanonol, a type of flavonoid. China suppliers typically sell it in standardized HPLC-tested specifications, commonly 98% purity, as an off-white to white fine powder with CAS number 27200-12-0 . It is soluble in hot water and ethanol but presents formulation challenges due to its bitter taste .

However, it is the science that makes this ingredient compelling. Recent research shows DHM has strong redox-modulating capacity and regulates multiple kinase-mediated signaling pathways, including AMPK, PI3K/Akt, MAPK, and NF-κB . In simple terms, it acts on the body at a fundamental cellular level, addressing oxidative stress and inflammation that drive chronic disease .

The "Hangover Cure" and Liver Support Hero
DHM has gained mainstream attention for its effects on alcohol metabolism. It accelerates toxin breakdown by activating alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), the enzymes responsible for metabolizing alcohol . Importantly, it also reduces "brain fog" after drinking by blocking GABA receptors in the brain . For brands targeting the massive social wellness and functional beverage market, this positions DHM as a key ingredient for hangover-recovery gummies, shots, and ready-to-drink beverages. There is also specific research linking DHM to the inhibition of liver fibrosis and the reduction of serum transaminase (ALT/AST) levels .

Beyond the Liver: Diabetes and Weight Management
While the liver protection angle is significant, the therapeutic potential of DHM extends much further. A 2026 review published in Food & Function highlighted that DHM improves glucose metabolism and alleviates oxidative stress and inflammation, making it relevant for managing diabetes and its complications .

Similarly, recent studies have explored DHM's impact on obesity. Research published in 2025 demonstrated that DHM inhibits adipogenesis—the formation of fat cells—by restoring lipid homeostasis. It was found to reduce body weight gain in high-fat diet models and disrupt lipid droplet formation .

Cognitive and Cardiovascular Health
Emerging evidence suggests DHM is neuroprotective. A 2025 study published in Phytomedicine indicated that DHM improves cognitive function in cases of vascular dementia by promoting angiogenesis (the formation of new blood vessels) through the VEGFR2 pathway . These findings open up exciting possibilities for brain health supplements targeting an aging population.

The China Supplier Advantage
Manufacturing Scale and Specifications
Chinese suppliers dominate the production of DHM. Manufacturers typically use "dynamic continuous countercurrent extraction" and recrystallization processes to achieve purity levels exceeding 98% . They offer the ingredient in multiple specifications—ranging from 50% to 98% purity—accommodating different cost and formulation needs .

Certifications and Compliance
Quality assurance is a priority for the leading Chinese manufacturers. Many operate under GMP, ISO, HACCP, KOSHER, and HALAL certifications . Major players are also establishing planting bases and adhering to EU standards for pesticide residues and heavy metals, aligning with the needs of international buyers in regulated markets .

Customization and Application Support
Chinese suppliers are offering more than just raw powder. Many provide private-label services, turning DHM into final formats like tablets, capsules, and gummies . Given the ingredient's bitterness, some suppliers have developed flavor-masking technology and micronization processes to improve solubility and customer experience—key advantages for functional beverage brands .

Commercial Considerations for Buyers
When sourcing DHM from China, buyers should focus on specific factors. Purity verification is critical; HPLC analysis reports confirming the exact percentage, most commonly 98%, must be requested . The source material is also a concern; while DHM is often derived from vine tea, it can also be sourced from Hovenia dulcis. Ensuring the botanical source aligns with your product positioning is essential .

Another key consideration is the gap between preclinical promise and clinical reality. While the lab data on DHM is extensive, clinical translation remains constrained by limited human studies . Brands should be aware of this caveat when making claims.

The Bottom Line
Dihydromyricetin from China's vine tea supply chain represents a unique intersection of traditional plant use and modern pharmaceutical-grade science. With applications spanning liver support, metabolic health, weight management, and cognitive function, it offers versatility to brand owners. China’s wholesale suppliers provide the scale, purity, and customization needed to bring DHM-based products to market, making this ingredient one to watch in the global functional ingredients landscape.
