Synonyms: Vitamin C Cas No. 50-81-7 Molecular Weight: 176.13 Description: L-Ascorbic Acid is a powerful antioxidant and plays a vital role in many physiological functions. Chemical Structure: It is a water-soluble compound. Its structure is a six-membered ring with hydroxyl groups attached, making it highly reactive and capable of neutralizing free radicals in the body. Functions and Benefits: Antioxidant Activity: It helps protect cells from damage by neutralizing free radicals, which can otherwise lead to oxidative stress and contribute to aging and disease. Collagen Synthesis: L-Ascorbic Acid is essential for the synthesis of collagen, a protein that provides structure to the skin, blood vessels, and connective tissues. This is why Vitamin C is often associated with healthy skin. Immune Support: Vitamin C boosts the immune system by stimulating the production of white blood cells and promoting their function. It also helps the skin act as a barrier to pathogens. Iron Absorption: L-Ascorbic Acid enhances the absorption of non-heme iron (the type found in plant-based foods), which is important for preventing iron-deficiency anemia. Wound Healing: Due to its role in collagen production, Vitamin C is crucial for proper wound healing and tissue repair. Neurotransmitter Synthesis: It plays a role in synthesizing neurotransmitters like dopamine, which is involved in mood regulation. Prevention of Scurvy: A deficiency in Vitamin C can lead to scurvy, a condition marked by weakness, gum disease, and skin problems. Dietary Sources: L-Ascorbic Acid is found in a wide variety of fruits and vegetables. Some of the richest sources include: Citrus fruits (oranges, lemons, grapefruits) Strawberries Kiwi Bell peppers Broccoli Brussels sprouts Tomatoes Spinach Daily Recommended Intake: The recommended daily intake varies by age, sex, and life stage. For adults, L-Ascorbic Acid typically around 65–90 mg per day, with an upper limit of 2,000 mg per day to avoid potential side effects like stomach upset. Skincare Benefits: Brightening & Hyperpigmentation: It is a popular ingredient in skincare for its ability to brighten skin tone and reduce dark spots or hyperpigmentation caused by sun exposure or acne scarring. Anti-Aging: Its antioxidant properties help protect against damage from UV rays and pollution, which can accelerate aging. Collagen Production: L-Ascorbic Acid promotes collagen synthesis, making the skin firmer and more youthful. Topical Use in Skincare: Stability:It is sensitive to light, air, and heat, which can cause it to degrade. That’s why it’s often packaged in opaque, airtight containers, and it’s recommended to store it in a cool, dark place. Concentration: Skincare products typically contain ascorbic acid in concentrations ranging from 5% to 20%. Higher concentrations can be more effective but may also cause irritation for sensitive skin. Possible Side Effects: In skincare, high concentrations of ascorbic acid can cause skin irritation, redness, or dryness, especially for those with sensitive skin. It’s usually advised to patch-test new products. In excessive amounts through supplementation, It can lead to digestive disturbances like diarrhea or kidney stones.
