🧪 Formulation Notes

Vitamin C is essential for healthy immune defenses and collagen formation as well as for the structure of virtually every organ of the body. C-Ascorbs is the ultimate high-potency vitamin C that features sustained release, is enhanced with a standardized lemon bioflavonoid complex and is pH buffered for maximum stomach comfort. Ascorbates are minerals that combine with ascorbic acid to produce stable, pH neutral, easy-to-digest-and-absorb vitamin C complexes.

Free from artificial colors and artificial preservatives. Free from all of the major allergens identified in the U.S. Food Allergen Labeling and Consumer Protection Act.
