What Is Vitamin C & What Does It Do?


Also known as Ascorbic Acid, Vitamin C is one of 12 water-soluble vitamins that your body cannot store for later use.

So it’s essential to ensure you and your family are getting enough of this vital vitamin from your diet on a daily basis.

In this post, I give you a brief history of how Vitamin C was first identified as being a vitamin and an essential one at that.

I’ll discuss some of the many benefits vitamin C has, and what signs to look out for, that may indicate a deficiency.

We’ll also have a look at some research, and foods guaranteed to give you that extra boost of vitamin C daily.

Below I have highlighted the important bits for you, just in case your schedule is tight.

A significant player regarding the integrity, structure and function of the immune system, Vitamin C helps protect your body and mind from infection, disease, stress, including nervous breakdown.

A Little Bit of History

Vitamin C played a significant role in the treatment of Scurvy which effected thousands of sailors between the 16th and 18th century.


It is a severe condition that leads to easy bruising and bleeding, lethargy, muscle weakness, chronic gum disease and skin problems.

Scurvy resulted in gross vitamin C deficiency due to diet and the lack of citrus fruits and fresh vegetables. (a factor they did not understand time)

In 1747, whilst at sea, a Scottish naval physician James Lind conducted an experiment using three sailors groups.

James Lind physically demonstrated that eating citrus fruits such as oranges physically, lemons, and limes prevented, treated, and cured scurvy.

What Are The Benefits of Vitamin C

Vitamin C has so many lead roles and functions that the benefits are endless. Here I list just a few, starting with the most beneficial to you, your immune system and general overall health.

Vitamin C the other sunshine vitamin.
Vitamin C & Vitamin D3 are the two Sunshine vitamins.
  • When you need to give your immune system a good boost, vitamin C must be one of the first supplements you consider first.  It boosts your immune system by defending your body from free radicals that damage cells as a powerful antioxidant.
  • Vitamin C also plays a crucial role in the nervous system’s physiology by regulating and supporting your mood and emotions.


Collagen is a protein in which there are 16 types; however, the collagen in your body is either type 1, 2 or 3.

Types 1 and 3 is found in your organs, bone, skin, ligaments and tendons.

Type 2 is found in the cartilage around the joints of your body.

Because of this, vitamin C supplement is used in the treatment of arthritis.

I Wouldn’t Be Without My Vitamin C

Sometimes we all need an extra boost depending on circumstance; I have been taken a daily supplement of vitamin C for the past year.

I still ensure I maintain a healthy balanced diet, ensuring I also get the vitamins and minerals I need from what I eat and drink.

Supplements are just that, supplements; they are not meant to replace meals but complement your diet, adding that extra layer of security, ensuring you provide your body with everything it needs.

The benefits are so worth it, I’ve noticed my joints and lower back don’t trouble me as much dealing with past British winters.

My hair has grown thicker (it was starting to thin out from the hairline, too), my nails are much stronger and longer than they ever have before.

I’ve had no colds, flu, the dreaded COVID 19 or any other illness or disease, so far, touch wood.

2020 was such an awful year I felt I needed to find natural ways to keep my physical health, stress levels, energy and sanity in check.

Let’s Get Back to the Benefits

  • Supports eye health, precisely that of the corneas in your eyes due to its powerful antioxidant and wound healing properties.
  • Enables easier absorption of iron from plant-based foods, a crucial mineral needed in the manufacture and production processes of red blood cells.
  • Along with other vitamins such as B12, vitamin C helps and influences lipid metabolism and cholesterol decrease.
  • Vitamin C is also a powerful antioxidant that prevents and neutralises unstable molecules and radicals. These are significant contributors to cell damage, particularly the skin. (including, but not limited to the onset and process of old age, making it another fantastic addition to Mother Natures make up bag)
Vitamin C helps keep wrinkles, cells and the onset of old age at bay.

Vitamin C Deficiency

A lack of vitamin C in your body weakens the immune system drastically and can cause a condition called anaemia which hinders the body’s ability to absorb iron from food.

A lack of this essential nutrient can also cause gum disease, severe tooth decay, slow, poor wound healing, joint pain, depression accompanied by a lack of energy, focus, and concentration.


Research has shown Vitamin C may also lower the risk of some cancers, particularly those of the mouth, esophagus, stomach, and breast.

Using supplements over time may also protect your eyes against cataracts.

Best Food Source

Super foods packed with Vitamin C goodness.

Thankfully Scurvy and most Vitamin C deficiencies are rare nowadays due to the easy access of a wide and varied range of fruit and vegetables we have at our disposal.

Just be sure you are getting enough from your diet; either top up on your next shopping trip, or you may want to consider supplementing your diet like me.

Here are just a few: 

  • fruits  (especially citrus)
  • fruit juice
  • potatoes
  • broccoli
  • bell peppers
  • spinach
  • strawberries
  • tomatoes
  • brussels sprouts

My Thoughts

As I’m sure you will agree, Vitamin C is indeed an essential vitamin and in so many ways.

It’s not just your physical body that you need to look after and pay attention to, but also your stress levels, emotions and moods.

2020 was not an easy year by any measure, what with the COVID 19 pandemic, lock down’s home and job losses and protests, brutality, fake news and alternative truths.

2020 was such a stressful year for just about everyone.
In 2021 you must take stock of your overall health, physical, mental & spiritual.

2021 hasn’t started any better; we have all witnessed the awful riots at the Capitol in Washington, DC, on January 6th and across the United States.

The future looks uncertain, and as you move forward into the new year, you will be faced with more complex challenges that you will have to overcome.

Looking after you has to be a priority to be physically and mentally prepared for what may come in this very different world.


Look after your body; after all, it is a temple; ensure you take great care of your immune system as it is the best line of defence you have at your intimidate disposal.
