In this blog, we'll take a closer look at the key benefits of Vitamin C and how you can incorporate it into your daily routine for optimal health and wellness.

What is Vitamin C? 

Vitamin C is probably the world’s most well-known vitamin. Vitamin C is classed as an essential vitamin as the body cannot make it and as a result, we need to obtain it in our diet. 

Vitamin C, also known as ascorbic acid, is a powerful antioxidant that is found in fruit and vegetables. It has many important functions in the body and plays a vital role in immunity, reducing tiredness and fatigue, improving energy and skin health. 

Antioxidants protect the body against harmful free radicals that damage cells and can cause inflammation and mutations. These antioxidant properties make vitamin C a cell protector and a booster of the bodies defence against viruses’, colds and flu. Those with low vitamin C levels have also been linked to have a higher risk of chronic diseases like dementia and heart disease. 


What is Vitamin C good for? 

If you were to ask what does vitamin C do and what is it good for, it would be impossible to sum it up in a few words. This water-soluble vitamin has many health benefits and plays a central role in functions ranging from immune support to energy. This article provides a comprehensive overview of the benefits of vitamin C.

Function of Vitamin C in your body

Vitamin C has several functions within the body. The most well-known functions, and those that you may have already heard of, are its role in maintaining the normal function of the immune system and contributing to energy production. These benefits make it the perfect vitamin for when you are feeling ill with cold or flu symptoms. Not only does it help support your immune system, but it also has the added benefit of acting as a ‘pick me up’ helping reduce tiredness and fatigue. 

Interestingly, vitamin C also has a role in normal collagen formation which benefits blood vessels, bones, cartilage, gums, skin and teeth. Vitamin C is even made into serums that can be spread on to the skin due to its skin hydrating and brightening properties, whilst promoting collagen production. Vitamin C is a potent antioxidant so helps to protect the body from harmful free radicals. 

One of vitamin Cs lesser-known functions is that it increases iron absorption. It is quite often recommended that if you take an iron supplement for anaemia you should also take it alongside a vitamin C supplement to help its absorption and effectiveness.  


8 Vitamin C Benefits 

  1. Immune support – Our immune systems are there to protect us from invading pathogens, viruses, bacteria and more! To function at its best, we need to make sure we are fuelling our bodies with the correct nutrition. It has been shown in studies that people who are deficient in vitamins like vitamin C are more susceptible to viruses and their recovery is longer. A study showed that regular vitamin C supplementation reduced the duration and severity of cold and flu symptoms in adults and children.  
  2. Supports energy metabolism and helps reduce tiredness and fatigue – when the body is put under stress like through intense exercise and illnesses like colds, we can simultaneously feel fatigued and lack energy. Ensuring that your body is supplied with enough vitamin C can help to reduce tiredness and give an energy boost. 
  3. Supports skin health – vitamin C is important in collagen production. It has shown to reduce dark circles and make skin look more radiant. It is important to get enough vitamin C through your diet, but it can also be applied directly to the skin in serum or cream form. 
  4. Helps create vitamin E – vitamin E is a potent antioxidant and vitamin C actually plays a role in converting by-products from certain bodily processes into vitamin E!  
  5. May help to manage weight and burn fat – a study has shown that individuals with an adequate intake of vitamin C burnt 30% more fat during exercise compared to those with a low vitamin C level. 
  6. Shown to reduce risk of disease – vitamin C is a potent antioxidant and helps protect the body against dangerous free radicals that can lead to chronic diseases like cancers and heart disease
  7. Helps prevent deficiency in iron – vitamin C aids iron absorption in the body. This helps increase the uptake of iron by the blood stream and helps iron levels to increase, ensuring dietary iron consumption is optimised. Iron is an important component of blood and if we don’t absorb enough, it can have negative effects on our health including tiredness and fatigue. 
  8. Helps protect future memory and brain health – a review of data was carried out that showed that those with higher levels of vitamin C have better brain function.
