Pure Quercetin Powder

Pure Quercetin Powder can be extracted from a variety of plants, it is a very good expectorant, has a good expectorant cough. It also has the effect of anti-tumor, anti-inflammatory, reducing blood pressure, assisting coronary heart disease and hypertension patients.

Healthkintai^® utilizes proprietary high-speed countercurrent chromatography technology to efficiently purify and scale up quercetin production, achieving product purity exceeding 98%, with some batches exceeding 99%. The company boasts a portfolio of nearly 3,000 natural product monomers, including its core product, quercetin, which has been exported to countries such as Switzerland, Singapore, and Germany, and has received numerous international quality certifications.

• Nanoformulation Development: In view of the poor water solubility of quercetin (1 mg/L), liposome encapsulation technology is used to increase the bioavailability to 45%.
• Glycoside derivative research: Explore the synergistic effect of derivatives such as quercetin-3-gentiobioside (CAS 7431-83-6) to enhance its antiviral activity.
• Green synthesis process: Use microbial fermentation to produce Pure Quercetin Powder precursors to reduce dependence on plant resources.​​​​​​​​​​​​​​

Quercetin not only possesses significant antioxidant and anti-inflammatory properties but also effectively regulates six cellular signaling pathways, thereby delaying the aging process through multiple pathways. Studies have shown that quercetin mitigates oxidative stress damage to cells by scavenging free radicals, thereby effectively protecting cell function. Inflammation is considered a key factor in the aging process, and its inhibitory effect on inflammatory responses provides important support for its anti-aging effects. Furthermore, Pure Quercetin Powder modulates cellular signaling, delaying aging, by affecting pathways such as AMPK and mTOR.

1. Relieve Allergy Symptoms

Quercetin is known as a "natural antihistamine." It stabilizes mast cells, preventing them from releasing excessive histamine. Histamine is the key substance responsible for allergy symptoms such as sneezing, runny nose, and itchy eyes. It is effective in relieving seasonal allergies (such as hay fever) and allergic rhinitis.

2. Support Cardiovascular Health

Quercetin helps relax blood vessels and improve endothelial function. It protects blood vessels from damage through its anti-inflammatory and antioxidant properties. It can be used as an adjunct to prevent cardiovascular disease.

3. Boost Immune System Function

Quercetin not only indirectly supports immunity through its anti-inflammatory and antioxidant properties, but some studies have also shown that it has antiviral potential, possibly by inhibiting the replication of certain viruses (such as influenza and rhinovirus). Supplementation at the early stages of infection may help shorten the duration of illness.

4. Support Joint Health

For rheumatoid arthritis and osteoarthritis, its anti-inflammatory properties can help reduce joint pain, swelling, and morning stiffness. It is often used with bromelain, an anti-inflammatory enzyme, to enhance its effectiveness and absorption.

5. Potential Anti-Aging and Neuroprotective Effects

By scavenging free radicals in the brain and reducing oxidative damage, it may help protect nerve cells. Some studies are exploring its potential in preventing neurodegenerative diseases such as Alzheimer's disease.

6. Athletic Performance and Recovery

For athletes or those who exercise regularly, Pure Quercetin Powder may help increase mitochondrial biogenesis (improving endurance) and reduce muscle inflammation and soreness after exercise, accelerating recovery.

1. Nutritional Supplements and Functional Foods

This is quercetin's most traditional and established application area.

• Basic Dietary Supplements: As a "natural antioxidant," it can be used alone or in combination with vitamin C and bromelain to enhance immunity, combat aging, and combat environmental stress.
• Sports Nutrition: Used to reduce post-exercise muscle damage and inflammation, accelerate recovery, and improve endurance.
• Anti-Allergy Products: As a "natural antihistamine," it can relieve symptoms of seasonal allergies (such as hay fever) and allergic rhinitis.
• Joint Health Products: Used in combination with glucosamine, chondroitin, and other products to help relieve pain and inflammation caused by arthritis.
• Cardiovascular Health Products: Used to support vascular health and assist in regulating blood pressure and blood lipids.

2. Medicine and Health

This is the most active research area with enormous potential. Quercetin is primarily explored as an adjunctive therapeutic or preventive agent.

• Metabolic Syndrome: Research is underway to investigate its role in improving insulin resistance and regulating blood sugar and blood lipids.
• Cardiovascular Disease: Exploring its anti-atherosclerotic and cardiomyocyte-protective properties.
• Neurological Disease: Researching its potential to combat neuroinflammation and oxidative damage, with the goal of preventing or delaying neurodegenerative diseases such as Alzheimer's and Parkinson's diseases.

3. Animal Health (Pet Nutrition)

This application is an extension of human nutritional health, and the market is growing rapidly.

• Pet Anti-Allergy: Relieves allergic symptoms such as itching, redness, and swelling in dogs caused by the environment or food, a primary application in the pet sector.
• Joint Support: Helps relieve pain and inflammation in older dogs or large breeds with arthritis.
• Overall Health Support: Acts as an antioxidant, supporting the pet immune system and delaying aging.

4. Cosmeceuticals and Skincare

• Anti-Aging: Combats oxidative damage caused by ultraviolet (UV) rays, reducing wrinkles and hyperpigmentation.
• Soothing and Repair: Soothes sensitive, red, or irritated skin, suitable as an adjunct care for sensitive skin and dermatitis.
• Promoting Collagen Production: By reducing oxidative stress, it indirectly protects collagen from degradation, maintaining skin elasticity.

5. Functional Beverages and the Food Industry

As a natural additive, it enhances product stability and health benefits.

• Natural Preservative: Leveraging its antioxidant properties, it replaces or reduces the use of synthetic preservatives (such as BHT and BHA), extending the shelf life of fatty foods like cooking oils and meat products.
• Functional Ingredient: Added to sports drinks, health drinks, and energy bars, claiming its health benefits.
