Description
What It Does Delivers 24-hour vitamin C protection with a single daily dose. Unlike regular vitamin C that clears your system in hours, Ester-C's patented calcium ascorbate formula stays active in your immune cells for up to 24 hours. Enhanced with quercetin and berry bioflavonoids for maximum absorption.
Why It Works
PROVEN RETENTION: Clinical studies show Ester-C remains in white blood cells 24 hours — no other vitamin C can make this claim.
ENHANCED ABSORPTION: Contains L-threonate metabolites that improve cellular uptake compared to standard ascorbic acid.
STOMACH-FRIENDLY: Calcium-buffered process makes it less acidic and gentler than regular vitamin C.
SYNERGISTIC SUPPORT: Quercetin provides anti-inflammatory benefits while berry bioflavonoids boost vitamin C absorption.
What's Inside Clean vegan formula in vegetable capsules. Contains no dairy, wheat, gluten, peanuts or soy. Made in Canada to strict quality standards.
Why we carry it: The only vitamin C with published research proving 24-hour immune cell retention — results that matter.
