Essential-C & Flavonoids®


Ester-C® & flavonoids is a unique form of vitamin C enhanced with flavonoids for antioxidant, immune, and vascular support.

Ester-C® & flavonoids, consisting primarily of calcium ascorbate, is a natural, non-acidic water-soluble form of vitamin C that is distinguished by its unique chemical composition and biological activity. It is manufactured in an exclusive, water-based process that results in a mixture of naturally occurring vitamin C metabolites, including ascorbate, dehydroascorbate, and threonate. The bioflavonoids quercetin, rutin and pomegranate extract are free radical scavengers (antioxidants) that complement the roles of vitamin C. Quercetin helps maintain healthy mast cell function and moderates healthy leukotriene and prostaglandin metabolism, thereby helping to mediate the inflammatory response. Rutin and pomegranate extract provide important support for blood vessel integrity and healthy cell function.


What Ester-C & flavonoids does:

  • Enhances immune function
  • Provides antioxidant protection from free radical damage (oxidative stress)
  • Supports healthy cardiovascular function
  • Promotes healthy allergic and inflammatory responses
