Revealed from many studies, vitamin C acts as an enzyme, co-factor, co-substrate and a potent antioxidant for various body reactions and metabolic processes.


Although, humans are unable to produce this vitamin due to absence of L-gluconolactone oxidase enzyme. Therefore, vitamin C intake purely depends on the diet; major sources are citrus fruits (oranges and grapefruit), kiwi, broccoli, brussels sprouts, green and red pepper, strawberries, tomatoes, cantaloupe and potatoes.

  • Provides strong Antioxidant Protection

Antioxidants are crucial for the human body as they prevent free radical damage. Free radicals are molecules, generated either due to UV radiations or pollutants exposure or as by-products of metabolic processes. These molecules are extremely reactive and can harm cellular components, which may become the base of certain diseases.

Here antioxidants play their role and being a potent antioxidant; the presence of vitamin C is significant to counter such free radicals.


According to research studies, vitamin C also helps to protect other vitamins like vitamin E and vitamin A from the deteriorating effects of oxidation.


But How Vitamin C reverses the effect of free radicals?

By donating their electrons, vitamin C neutralizes the free radicals. However, the transfer of electrons does not turn the antioxidants into free radicals as they are stable in any form.



  • Protects From Numerous Cardiovascular Diseases



A problem in which arteries become narrowed due to build-up of cholesterol in the wall of the artery. The reason behind is the oxidative modification of low-density lipoprotein (bad cholesterol).

Vitamin C helps to prevent this oxidation of LDL. Along with this, vitamin C also strengthens the wall of arteries by preventing unwanted adherence of white blood cells to the artery wall and synthesizing collagen.


Cardiovascular Therapy Supplement

By improving nitric oxide production and neutralize reactive oxygen species, vitamin C helps to prevent specific problems occurring after certain cardiovascular therapies, consequently reduces hospital stay and helps in fast recovery.


Lowers Blood Pressure

Vitamin C also helps to reduce the blood pressure by enhancing nitric oxide production of endothelium and even suggested as an adjuvant for antihypertensive therapy.

  • Protects From Common Cold

Due to significant antihistamine effect and immune-boosting properties, vitamin C remarkably reduces the duration of the common cold.


  • Strengthens the Immune System

Vitamin C exhibits various significant positive impacts on the immune system of humans. It remarkably improves immunity by boosting the natural killer cell production and antimicrobial properties, chemotaxis and white blood cell growth.

  • Speeds up the Fat Metabolism

Vitamin C is an essential component of muscle carnitine synthesis, which is very necessary for fatty acid metabolism. This helps in improving burning off excessive fat which leads to a reduction in obesity.

  • Reduces the Risk Of Neurodegenerative Diseases

Vitamin C also helps to synthesis catecholamine, an essential neurotransmitter needed for transferring signals necessary to regulate processes such as blood pressure, blood glucose levels, fight or flight response, and heartbeat.

Besides this, it also strengthens the neuron structure and survival. All these lead to improved recognition, free recall and vocabulary.

  • Improves Iron Absorption

Conversion of ferric iron into ferrous iron is also the main attributes of vitamin C. It improves iron absorption in the body, thereby prevents anaemia, weak immunity and cognitive impairment.

  • Helps In Treating Eye Problems

In the eye lens, vitamin C is present in high concentrations.

Being a powerful reducing agent, it lowers oxidative stress and protects the lens. It is also beneficial for patients who are suffering from cataracts and macular degeneration. Except this, vitamin C maintains the integrity of the eye’s connective tissues and blood vessels.

  • Provides Photo-protection

Due to its extraordinary antioxidant properties, it protects skin from free radicals and the harmful effects of UVA and UVB rays. Not only this, but it also plays an essential role in collagen synthesis and reducing melanin formation. Vitamin C reduces the hyper-pigmentation by hindering the production of tyrosinase enzyme, which is crucial for melanin production.


All these vitamin C benefits provide human Health with a shield of protection from various diseases.


But, If the concentration of vitamin C increases in our body!

Well, vitamin C found to have very low toxicity and does not cause any significant side effects if taken in high doses.

But, when its concentration rises too high, it may cause problems like,

  • Abdominal Cramps
  • Nausea
