What is Vitamin C?

Vitamin C, or ascorbic acid, is a water-soluble vitamin — meaning your body doesn’t store it, so you need to replenish it every day through diet or supplements.

It’s naturally found in foods like:

•Citrus fruits (orange, lemon, grapefruit)

•Strawberries

•Kiwi

•Papaya

•Bell peppers

•Broccoli

Why Vitamin C is Essential

1.   Immune System Defense

Vitamin C strengthens white blood cell activity and boosts your body’s ability to fight infections. It’s why you’ll find vitamin C with zinc supplements everywhere during flu season.

2.     Skin Glow & Anti-Ageing

It stimulates collagen synthesis, keeping skin firm, youthful, and radiant while reducing wrinkles and pigmentation.

3.     Powerful Antioxidant

Vitamin C neutralises free radicals caused by stress, pollution, and UV rays, protecting your cells from damage.

4.     Faster Recovery & Healing

It accelerates wound healing and tissue repair, especially after workouts or illness.
