WHAT IS ASCORBIC ACID? – Vitamin C, or ascorbic acid, is a substance found in citrus fruits. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissue from oxidative stress. This essential vitamin also promotes the absorption of iron, while inhibiting its oxidation. It’s also a vital to producing collagen: a key protein for tendons, arteries, skin, bones and teeth.

THE FORM THAT FITS YOUR ROUTINE: Most vitamin C on the market starts from corn — refined, acidic ascorbic acid that sits uncomfortably with sensitive stomachs and works against the alkalizing routine many adults are trying to build. Alkalini-C uses 100% l-ascorbate, the fully reduced, fully buffered form of vitamin C that is genuinely corn-free, pH-neutral rather than acidic, and easy on digestion from the first tabsule. One thousand milligrams per tabsule, the form that fits, every single day.
ALKALIZING, NOT ACIDIFYING: Standard ascorbic acid carries an acid load into your day with every dose. Alkalini-C doesn’t — the l-ascorbate form metabolizes as an alkalizing compound, consistent with a pH-balanced supplement protocol instead of working against it. The calcium it’s paired with is calcium ascorbate — 111 mg per tabsule, the same alkalizing mineral form. Every ingredient on this label is disclosed at its precise amount in the Supplement Facts panel.
