Vitamin C (Ascorbic Acid): Immune Support and Antioxidant Defense
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for numerous physiological functions, ranging from immune support and collagen synthesis to antioxidant protection and iron absorption. Unlike most animals, humans cannot produce vitamin C endogenously, making consistent dietary intake or supplementation critical. In longevity-focused health routines, vitamin C plays a foundational role in cellular protection, tissue repair, and healthy aging.
Powerful Antioxidant for Cellular Longevity
Vitamin C is a potent antioxidant that neutralizes reactive oxygen species (ROS) and helps protect cells from oxidative stress. By reducing oxidative damage to proteins, lipids, and DNA, vitamin C supports the body's ability to maintain cellular function and delay biological aging. This antioxidant role is especially important for individuals exposed to environmental stressors, inflammation, or metabolic imbalances.
Immune Function and Inflammation Control
Vitamin C contributes to both innate and adaptive immune responses. It supports the production and activity of white blood cells, enhances epithelial barrier integrity, and helps modulate inflammation. Studies have shown that vitamin C supplementation may reduce the severity and duration of infections, particularly in individuals with low baseline levels or elevated physiological stress.
Collagen Formation and Skin Health
As a cofactor in collagen synthesis, vitamin C is essential for the maintenance of connective tissue, skin elasticity, and wound healing. It contributes to the structural integrity of blood vessels, cartilage, and bones. In anti-aging and skin health contexts, adequate vitamin C levels help reduce signs of aging by supporting dermal structure and resilience.
Bioavailability and Supplementation
Our supplements use highly bioavailable forms of vitamin C, formulated for gentle absorption and optimal plasma concentration. Each batch is third-party tested to verify potency, purity, and the absence of contaminants. For enhanced effectiveness, vitamin C is often paired with bioflavonoids or buffered to reduce gastrointestinal discomfort—making it suitable for daily, long-term use.
