Ascorbic acid, commonly known as Vitamin C, is an essential water-soluble nutrient and potent antioxidant vital for immune function, collagen synthesis, and wound healing.

Because the human body cannot produce or store it, it must be consumed daily through foods like citrus fruits and vegetables or via supplements.

Key Aspects of Ascorbic Acid (Vitamin C):
Health Benefits: Supports collagen production for skin and joints, enhances iron absorption, and acts as an antioxidant to protect cells from free radicals.

Deficiency: Lack of Vitamin C leads to scurvy, causing fatigue, gum disease, and poor wound healing.
Dietary Sources: Citrus fruits (oranges, grapefruit), kiwi, berries, and vegetables (broccoli, peppers).

Supplementation: Available as pills or powder, often used to boost immune health. Common dosages range, with 50 mg/day used for scurvy prevention.

Safety: Generally safe, but excessive doses (over 2000 mg/day) may cause stomach upset or increase the risk of kidney stones.

For most people, a balanced diet provides sufficient vitamin C, but supplements are used for deficiency or extra immune support.
