The cardiovascular implications of dietary supplements and functional foods warrant continued investigation. Among naturally occurring flavonoids, interest in the antioxidant, anti-inflammatory, vascular and lipid-related implications of dihydroquercetin/taxifolin is increasing.

For brands of dietary supplements, Contract Manufacturer’s (CMs) capabilities, and product formulators, the ability to source Wholesale Dihydroquercetin Powder with the appropriate product specifications and supporting documentation is critical. Based on the experience of B-Thriving, this article focuses on the product specifications for dihydroquercetin and the proposed cardiovascular mechanisms and formulation considerations.
What is Dihydroquercetin?
Dihydroquercetin is a natural dihydroflavonol found in some fruits and plants. As a common commercial source, larch wood is used. Dihydroquercetin is similar to quercetin, but in the C2-C3 bond, dihydroquercetin is completely saturated, and this change alters the stability and the chemical properties of the compound.
Wholesale Dihydroquercetin Powder of high purity can be used in capsules, tablets, premixes, powdered supplements and functional nutrition products.
•Botanical source: For commercial use, dihydroquercetin is primarily extracted from Larix species.
•Active content: Dihydroquercetin in a commercial product is at least 98% and is controlled by HPLC.
•Appearance: This ingredient appears as a fine powder that is pale yellow in color.
•Application formats: This ingredient, in powdered form, can be conveniently used for tablets, capsules and blends.
Mechanisms of Potential Cardiovascular Support
With respect to the potential effects of Dihydroquercetin, it is possible that the mechanisms can have several effects within interrelated biological systems.
1. Antioxidant Defense
The damage caused by oxidative stress to the endothelium can induce the oxidation of lipids and lipoproteins. Dihydroquercetin may provide the means to interact with the reactive species as a function of its hydroxyl groups.
•Free radical scavenger: Dihydroquercetin may be capable of neutralizing superoxide and hydroxyl radicals, as well as other reactive species.
•Metal ion chelator: Dihydroquercetin may bind to, and thus inactivate, the oxidizing catalysts copper and iron.
•Lipid protection: Dihydroquercetin may inhibit the oxidation of membrane lipids and lipoproteins.
•Support of antioxidant network: Dihydroquercetin may provide support for vitamin C and glutathione systems and related networks.
2. Vascular Inflammation
Dihydroquercetin may be involved in the modulation of vascular tissue and the endothelium by affecting various pathways related to inflammation.
•NF-κB: Some studies indicate that Dihydroquercetin may inhibit the NF-κB pathway.
•Expression of adhesion molecules: Dihydroquercetin may affect the expression of VCAM-1 and ICAM-1.
•Inflammatory cytokines: Animal studies indicate that Dihydroquercetin may affect TNF-α, IL-6, and other inflammatory cytokines.
Dihydroquercetin helps to maintain the structural and functional integrity of the endothelium by modulating the combined effects of oxidative and inflammatory stress.

3. Lipid Metabolism
Dihydroquercetin may affect lipid metabolism and atherogenesis.
•Lipid metabolism: Dihydroquercetin may inhibit the oxidative modification of LDL.
•Cholesterol translocation: Evidence indicates that dihydroquercetin could include cholesterol efflux facilitation.
•Lipid metabolism: Some animal studies suggest that dihydroquercetin could affect hepatic lipogenesis and triglyceride formation.
•Plaque-related mechanisms: There are oxidative and inflammatory processes that may, in an indirect sense, assist in the stabilization of the vasculature.
Due to insufficient evidence from human studies, no conclusions can be made regarding the control of lipids.
4. Endothelial Function and Nitric Oxide
Well-functioning endothelium is essential for the control of blood flow and distribution of nutrients. Central to these processes is nitric oxide.
•Support of the eNOS pathway: It is suggested that Dihydroquercetin may have a positive effect on the activity of the endothelial nitric oxide synthase enzyme.
•Protection of nitric oxide: It is proposed that the antioxidant activity of Dihydroquercetin may reduce the scavenging of nitric oxide by superoxide.
•Vascular relaxation: The availability of nitric oxide may assist in the relaxation of blood vessels.
•Microcirculation: Support of the endothelium is likely to assist in the flow of blood in the cardiac and peripheral tissues.
5. Platelet Function
The influence of Dihydroquercetin on platelet activity has been studied.
•Platelet signaling: It is suggested that Dihydroquercetin may have an effect on thromboxane and related intracellular signaling in platelets in vitro.
•Aggregation response: Under particular conditions, platelet aggregation was affected to a moderate degree.
•Combination use: Dihydroquercetin is sometimes combined with other polyphenols in broader cardiovascular formulas.
These findings should not be interpreted as a replacement for prescribed antiplatelet medication or medical treatment.
