Premium MCP (Modified Citrus Pectin)

Advanced Ingredient for Cellular Health and Immune Support

Modified Citrus Pectin (MCP) is a specialized form of citrus pectin produced through controlled modification processes that reduce molecular weight and degree of esterification, improving solubility and bioavailability.

Derived from citrus peel, MCP has gained significant attention in nutraceutical and biomedical research for its potential role in supporting immune health, cellular wellness, and healthy inflammatory balance.

At Skywin International, we supply high-quality Modified Citrus Pectin developed through advanced processing technologies to ensure optimal molecular characteristics, consistent quality, and reliable performance in dietary supplement formulations.

Key Features
  • Low Molecular Weight
  • Low Degree of Esterification (DE)
  • High Galacturonic Acid Content
  • Excellent Water Solubility
  • Ideal for Nutraceutical Applications

Quercetin

Available Grades

• Quercetin 95% (HPLC)
• Quercetin 98% (HPLC)
• Quercetin Dihydrate
• Customized particle size for formulation

Quercetin is a naturally occurring plant flavonoid widely distributed in fruits, vegetables, and botanical sources such as Sophora japonica. Recognized as one of the most abundant dietary flavonoids, quercetin is valued for its antioxidant and immune-support properties and is widely used in dietary supplements and functional nutrition formulations.

At Skywin International, we supply high-purity quercetin designed for modern nutraceutical applications, ensuring consistent quality, reliable supply, and formulation compatibility.

Key Features

• Powerful antioxidant activity
• Supports immune system balance
• Helps maintain cardiovascular health
• Supports healthy inflammatory response
• Suitable for immune and longevity formulations

Berberine

(Plant-Derived Alkaloid) 

Available Grades

• Quercetin 95% (HPLC)
• Quercetin 98% (HPLC)
• Quercetin Dihydrate
• Customized particle size for formulation

Berberine is a naturally occurring isoquinoline alkaloid extracted from botanical sources such as Coptis chinensis, Berberis aristata, and other traditional medicinal plants. Historically used in traditional medicine, berberine has gained significant attention in modern nutraceutical research for its role in supporting metabolic health, cardiovascular function, and digestive balance.

Scientific studies suggest that berberine may help regulate glucose metabolism, support healthy lipid levels, and improve insulin sensitivity through activation of metabolic pathways such as AMPK, a key enzyme involved in energy regulation.

At Skywin International, we supply high-purity berberine designed for advanced nutraceutical formulations, ensuring consistent quality, reliable sourcing, and formulation compatibility

Key Features
