• People commonly seek this supplement for its potential benefits in boosting immunity, supporting skin health, and providing antioxidant protection.

Historical Background / Traditional Use

• Vitamin C has been recognized for its health benefits since the 18th century when it was used to prevent scurvy among sailors. Its role in immune support and skin health has been acknowledged in various traditional medicine systems.
• Modern usage focuses on its antioxidant properties and its role in collagen synthesis, which were not fully understood in historical contexts.

Composition and Active Components

• The primary active component is Vitamin C, provided in the form of calcium ascorbate. This form is less acidic than ascorbic acid, making it suitable for individuals with sensitive stomachs.
• Calcium is included as part of the calcium ascorbate compound, contributing to daily calcium intake.
