Explore our core standardized botanical derivatives engineered to meet international quality control standards.
As international consumer demand shifts toward clean-label and clinically-backed active compounds, Dihydroquercetin (DHQ), also widely classified as Taxifolin, has emerged as a premium bioactive flavonoid. Primarily derived from larch wood sources (such as Larix sibirica), DHQ represents a significant structural advancement over standard quercetin, possessing superior water solubility, exceptional bioavailability, and a significantly higher safety profile.
Global R&D sectors are integrating wholesale Dihydroquercetin for its profound biological properties: acting as an ultra-potent free radical scavenger, supporting microcirculation stability, limiting lipid peroxidation, and extending the shelf-life of complex formulations. In clinical contexts, Taxifolin works synergistically with ascorbic acid, stabilizing cell membranes and modulating inflammatory pathways.
For international buyers and product developers, securing a consistent, traceably sourced supply of pharmaceutical-grade DHQ is vital to maintaining batch uniformity and ensuring market compliance under rigorous regulatory regimes like EFSA and FDA.

A comparative look at why product formulators prefer Taxifolin for high-efficacy modern nutraceuticals.
| Evaluation Parameter | Dihydroquercetin (Taxifolin) | Standard Quercetin | Formulation Benefit |
|---|---|---|---|
| Chemical Structure | Hydrogenated structure (no double bond in the C-ring) | Double bond present between C2 and C3 | Lower toxicity thresholds, improved metabolic pathways |
| Bioavailability Rate | High (rapid absorption in the GI tract) | Extremely low (often requires complex excipients) | Enables lower effective dosage targets in end products |
| Water Solubility | Significantly improved (approx. 1.2 g/L at room temp) | Virtually insoluble in water (approx. 0.002 g/L) | Excellent performance in functional beverages & cosmetics |
| Sensory Profile | Very mild, neutral taste/color profile | Bitter, strong yellow pigment characteristics | Prevents discoloration or off-flavors in food matrixes |
| Antioxidant Capacity | Exceptional ORAC values (sustained action) | High peak capacity but rapid breakdown | Longer shelf-life stabilization for target products |

Three pillars supporting our manufacturing consistency, ensuring security for contract manufacturers and buyers.
Quality and safety are non-negotiable. Every batch undergoes rigorous testing in our in-house laboratories, equipped with HPLC, GC-MS, and other advanced analytical instruments. We guarantee compliance with stringent international standards, including ISO, NSF, cGMP, and related certifications. Our commitment to transparency means you receive comprehensive Certificates of Analysis (CoA) for every product, ensuring traceability and peace of mind.
It’s one thing to just meet the regulations when providing ingredients, but when an ingredient supplier exceeds those standards and imposes even higher ones in its products that is a sign of a company who cares. Andy Biotech takes extra steps to ensure that our independent third-party laboratory-tested ingredients you want meet our standards as well as your own.
Our extensive portfolio features a wide range of standardized extract, ratio extract, and custom blends tailored to specific formulations. Whether you need Echinacea for immune support, Turmeric with high curcuminoid content, or innovative botanical blends for skincare, our technical team works closely with you to deliver exactly what your product requires. Andy Biotech provide high quality Ginkgo Biloba Extract, Lycopene Tomato Extract, Lutein Marigold Extract, Aloe Vera Gel Freeze Dried powder Aloe Vera Extract and other natural ingredients.
Providing functional application methodologies to overcome technical formulation boundaries across sectors.
Within clinical formulas, Dihydroquercetin acts as a capillary-stabilizing and cardioprotective agent. By protecting erythrocytes and improving capillary permeability, it is key for formulations focused on diabetic microangiopathy, cardiovascular support, and lipid regulation. As premium exporters, we provide low-microbial, ultra-pure powders optimized for tableting, capsule filling, and dry syrup suspensions.
The cosmetic market integrates Dihydroquercetin to prevent UV-induced collagen degradation and melanogenesis. Its powerful anti-elastase and anti-collagenase pathways make it an active ingredient in premium anti-aging creams, serums, and sun protection formulas. Its high solubility ensures clean emulsion phases without crystallization or separation issues over shelf-life cycles.
As food safety regulations restrict synthetic preservatives like BHA, BHT, and propyl gallate, Dihydroquercetin offers a natural alternative. Its high antioxidant capacity prevents oil oxidation and extends shelf-life in functional fats, milk powders, and meat products without altering flavor profiles. Its heat stability makes it ideal for pasteurized functional beverages and baked goods.
With global bans on antibiotic growth promoters, animal feed producers use Taxifolin to manage intestinal oxidative stress in livestock. Incorporating standard and custom-mesh DHQ into veterinary feeds supports immune response, mitigates heat stress, and improves lipid quality in dairy and poultry production.
A heritage deeply rooted in natural botanical wisdom and a commitment to spreading healing power globally.
Andy was born in a small village close to Hanjiang River in Hanzhong Shaanxi province, China. Thirty years ago, when she was still a little child, she caught a cold, but the medical services were not available unless the family crossed over high mountains to find a hospital. Thus, Andy's grandfather first used Echinacea leaves soaked in water for her treatment, then he dug Echinacea root and shredded into pulp and squeezed the liquid for Andy to drink one spoon every two hours. Andy recovered after this treatment.
As a child, Andy watched his grandfather harness the healing power of plants in his humble garden. His ancient herbal remedies were not just treatments; they were magic. That early wonder blossomed into a profound passion for plant extracts and a deep respect for nature’s wisdom. From that time on, little Andy swore that he would help to spread all herbs all over the world to give benefit to more people.
This personal journey is the heart of Andy Biotech. It’s why Andy Biotech are dedicated to researching and delivering the purest, most effective botanical solutions for modern wellness. Andy’s lifelong vow is to honor that tradition by innovating for a healthier future, empowering lives through the timeless power of plants.
