I. Introduction
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a vital role in maintaining your overall health. Best known for its immune-boosting powers, it also helps with collagen formation, iron absorption, and skin regeneration. Unlike some vitamins, your body cannot produce or store Vitamin C, making it essential to consume it regularly through diet or supplementation.
Let’s dive into why Vitamin C is so essential and how to make the most of it in your daily routine.

What is Vitamin C / Ascorbic Acid?
Vitamin C is an essential micronutrient and antioxidant that helps protect your body from oxidative stress caused by free radicals. It’s also crucial for enzyme function, tissue repair, and the synthesis of neurotransmitters.
Humans, unlike most animals, cannot synthesise Vitamin C internally. That means we need to get it from our diet, primarily through fruits, vegetables, or supplements.
Top 10 Health Benefits of Vitamin C
1. Boosts Immunity
Vitamin C enhances the production and function of white blood cells, the key soldiers in your immune system. It also strengthens skin barriers to pathogens and reduces the duration of common colds.
2. Powerful Antioxidant
As a potent antioxidant, Vitamin C neutralises free radicals that damage cells and cause ageing and chronic diseases.
3. Promotes Healthy Skin
Vitamin C is crucial for collagen synthesis, which keeps your skin firm, youthful, and elastic. It also helps reduce hyperpigmentation, sun damage, and acne scars.
4. Speeds Up Wound Healing
Vitamin C aids in faster healing of cuts, wounds, and even post-surgical recovery by supporting new tissue growth and reducing inflammation.
5. Enhances Iron Absorption
This vitamin increases the absorption of non-heme iron (from plant sources), making it an excellent companion for those at risk of anaemia.
6. Supports Heart Health
By reducing oxidative stress, Vitamin C lowers blood pressure, improves blood vessel function, and helps prevent atherosclerosis.
7. May Reduce Risk of Chronic Diseases
A diet high in Vitamin C is associated with a reduced risk of chronic conditions like heart disease, stroke, and certain cancers.
8. Improves Brain Function
Vitamin C plays a role in the production of neurotransmitters and may protect against neurodegenerative diseases like Alzheimer’s.
9. Acts as an Anti-Inflammatory Agent
It helps reduce systemic inflammation, making it beneficial for conditions like arthritis and autoimmune diseases.
10. Helps with Skin Brightening (Topically)
When used in serums or creams, topical Vitamin C can fade dark spots, improve skin tone, and give your skin a radiant glow
