Description

Procyanidin C1 is a naturally occurring oligomeric proanthocyanidin, a subclass of polyphenolic compounds known for their potent antioxidant properties. This high-purity compound is critical for research and development in nutraceuticals and pharmaceuticals, where standardized bioactive ingredients are required. It is primarily sought by manufacturers in the dietary supplement, cosmetic, and functional food industries for formulating products targeting oxidative stress and promoting cellular health.

Application

• Dietary Supplements & Nutraceuticals: Used as a key active ingredient in capsules, tablets, and powders for its strong antioxidant and potential cardiovascular support benefits.
• Cosmetic & Skincare Formulations: Incorporated into anti-aging serums, creams, and lotions for its ability to protect skin from free radical damage and support collagen integrity.
• Functional Food & Beverage Enrichment: Added to health drinks, fortified foods, and confectionery to enhance nutritional profiles with natural polyphenols.
• Pharmaceutical Research & Development: Serves as a reference standard and active pharmaceutical ingredient (API) intermediate in preclinical studies for metabolic and inflammatory conditions.
• Biochemical Research: Utilized in laboratory studies to investigate mechanisms of antioxidant activity, cell signaling pathways, and bioavailability of procyanidins.
