Understanding Oxidative Stress

Oxidative stress arises as a natural by-product of cellular metabolism and is amplified by environmental pollutants, UV radiation, sustained physical exertion, and psychological stress. When antioxidant defences are insufficient, cellular membranes, proteins, and DNA can be progressively damaged — contributing to accelerated ageing, reduced immune capacity, and impaired tissue repair.

Vitamin C — Water-Soluble Antioxidant & Collagen Cofactor

Primary aqueous antioxidant, neutralises ROS and regenerates Vitamin E. Essential for collagen synthesis.

Vitamin C (as buffered calcium ascorbate) is the body's primary water-soluble antioxidant, operating in blood plasma and aqueous cellular compartments to neutralise reactive oxygen species and regenerate Vitamin E. It is also an essential cofactor for collagen hydroxylation — the enzymatic process by which the triple-helix structure of collagen is stabilised, making it indispensable for connective tissue formation, wound healing, and vascular integrity. The calcium ascorbate form is selected specifically to reduce gastrointestinal irritation associated with acidic ascorbic acid.

Vitamin E — Lipid-Soluble Membrane Protector

Mixed tocopherols protect cellular membranes and lipoproteins where Vitamin C cannot operate.

Mixed tocopherols Vitamin E concentrate (low-alpha type) provides lipid-soluble antioxidant protection within cellular membranes and lipoproteins. The low-alpha mixed tocopherol blend is preferred over isolated alpha-tocopherol, as it preserves the activity of gamma- and delta-tocopherols which contribute meaningfully to overall antioxidant and anti-inflammatory activity. Vitamin C regenerates oxidised Vitamin E, creating a self-reinforcing antioxidant network more effective than either nutrient in isolation.

Nicotinamide (B3) — NAD+ Metabolism & Cellular Energy

Supports NAD+ pathway, cellular energy production, nervous system, and skin structure. No flushing.

Nicotinamide (Vitamin B3) contributes to cellular energy production through its role in NAD+ metabolism, and supports healthy skin structure, nervous system function, and normal psychological function. Unlike nicotinic acid, nicotinamide does not cause the vasodilatory flushing response, making it well-tolerated at the dose provided.
