Dihydroquercetin

Q: Is Dihydroquercetin safe?

Generally, DHQ is considered safe; however, long-term effects and medication interactions require further study.

Q: How should Dihydroquercetin be taken?

There are no specific timing recommendations for DHQ; consistent daily intake is suggested for best results.

Q: What benefits can be expected from taking Dihydroquercetin?

Dihydroquercetin may improve cardiovascular health and could help mitigate the severity of diseases like COVID-19.

Q: Can Dihydroquercetin replace medical treatments?

No, DHQ is not a substitute for medical treatment but can complement therapy under healthcare supervision.

Also known as: Dihydroquercetin, Taxifolin

Overview

Dihydroquercetin (DHQ), also known as Taxifolin, is a flavonoid compound predominantly found in conifers and various fruits. It is a derivative of quercetin and is recognized for its potent antioxidant properties and diverse biological activities. Potential applications of DHQ include its use as a dietary supplement aimed at the prevention and treatment of cardiovascular diseases and possibly neurodegenerative diseases. Research indicates it exerts significant antioxidant, anti-inflammatory, antihypertensive, and vasoprotective effects. The research surrounding DHQ is growing, although further large-scale studies are necessary to establish its clinical applications, particularly in relation to its stereoisomerism and pharmacokinetics.

Benefits

Dihydroquercetin offers multiple evidence-backed benefits. Key findings suggest that it can enhance cardiovascular health by improving endothelial function, reducing blood viscosity, and preventing platelet aggregation, consequently aiding in the management of cardiovascular diseases. Additionally, while direct evidence for DHQ in COVID-19 is lacking, its structural similarities to quercetin, which has shown benefits in COVID-19 patient management, indicate potential use in similar contexts. The compound also exhibits significant anti-inflammatory and antioxidant properties, making it beneficial in various pathological states. Patients with arterial hypertension and other cardiovascular conditions are expected to benefit the most, with the treatment duration for noticeable effects potentially spanning several weeks to months.

How it works

Dihydroquercetin operates through various biological pathways, primarily involving its antioxidant and anti-inflammatory mechanisms. It modulates pathways related to oxidative stress and inflammation by interacting with nuclear factors such as NRF-2 and NF-κB. DHQ's benefits extend to its effects on the cardiovascular system, where it enhances endothelial function, reduces blood viscosity, and inhibits platelet aggregation, while also potentially affecting the nervous and immune systems.

Side effects

Dihydroquercetin is largely considered safe with limited documented side effects. Although direct side effect studies regarding DHQ are scarce, flavonoids are typically well tolerated. Common side effects (>5%) are not clearly defined, while no uncommon side effects (1-5%) have been reported. Rare side effects (<1%) remain largely undocumented, necessitating further investigation. Though comprehensive data on drug interactions is limited, it is advised that caution should be exercised when DHQ is administered alongside other cardiovascular medications due to its biological activities, notably its antiplatelet effects. Individuals with bleeding disorders should also avoid DHQ unless supervised by healthcare professionals, and pregnant or breastfeeding women are advised to consult healthcare providers prior to use.

Dosage

The recommended dosage range for Dihydroquercetin has not been universally established. However, studies on its relative, quercetin, suggest that doses exceeding 500 mg/day may yield cardiovascular benefits. Typical usage for DHQ tends to range between 100-500 mg daily. No specific timing for dosage has been identified, although improvements in health parameters are expected with consistent intake over time. Furthermore, Phytosome formulations may enhance the bioavailability of DHQ, similar to formulations for quercetin, indicating that absorption can be optimized through specific delivery formats.
