Vitamin C (ascorbic acid) is essential for collagen synthesis, immune function, and antioxidant protection.
Vitamin C, or ascorbic acid, is a water-soluble vitamin vital for numerous physiological processes. While it cannot be produced endogenously, it can be obtained through dietary sources or supplementation. It plays a key role in immune function by supporting immune cell activity, wound healing through collagen synthesis, and provides antioxidant protection by neutralizing free radicals. Furthermore, it aids in iron absorption. While generally safe, high doses can lead to gastrointestinal issues and, in susceptible individuals, increase the risk of kidney stones. Therefore, it is important to adhere to recommended dosages and consult with a healthcare professional when considering supplementation.

Production Process
Ascorbic acid is typically synthesized through a multi-step process often involving glucose. A common method is the Reichstein process, which involves converting glucose to sorbitol, then to sorbose, followed by a series of chemical reactions including oxidation and esterification to ultimately yield ascorbic acid.

BothPotential Benefits
Antioxidant support protects cells from damage by neutralizing free radicals, supporting immune function, and reducing inflammation. It contributes to overall health and may reduce the risk of chronic diseases.
Immune support enhances the body's defense against pathogens by strengthening immune cells, promoting antibody production, and maintaining immune homeostasis. It aims to optimize immune function for a balanced and resilient response to threats.
This benefit aims to improve overall skin health and appearance through increased hydration, reduced inflammation, improved elasticity, and protection from environmental damage. Healthy skin exhibits a smooth texture, even tone, and strong barrier function.
Antioxidant protection defends the body against free radical damage, reducing the risk of chronic diseases and promoting overall cellular health. This is achieved by neutralizing unstable molecules that cause oxidative stress and cellular damage.
Collagen synthesis is the body's natural process of producing collagen, a structural protein crucial for skin, hair, nails, joints, and tissue repair. Adequate synthesis supports skin integrity, hair/nail growth, joint health, and wound healing.
Possible Side Effects
Gastrointestinal upset involves a variety of digestive symptoms like nausea, diarrhea, and abdominal pain. It can range from mild discomfort to severe pain and may indicate an underlying condition if persistent.
Digestive upset includes various gastrointestinal symptoms like nausea, diarrhea, and abdominal pain, stemming from factors such as medication, diet, or infections. The severity and duration vary depending on the cause and individual sensitivity.
Kidney stones are hard mineral deposits forming in the kidneys, causing pain and potentially blocking urine flow. They are often caused by a combination of dietary, environmental, and genetic factors.
