Benefits of Vitamin C: Skin, Cells, Wound Healing and Food Sources
Vitamin C helps protect cells, supports skin, blood vessels, bones and cartilage, and is found in many fruit and vegetables.
What Vitamin C does
Vitamin C is an essential nutrient, meaning your body needs it in small amounts to work properly. The practical benefit is not that it gives you superpowers. It helps normal processes run as intended, which is less dramatic but much more useful.
Main benefits of getting enough Vitamin C
- Helps protect cells and keep them healthy
- Supports skin, blood vessels, bones and cartilage
- Helps with wound healing
- Supports iron absorption from plant foods when eaten together
Foods that contain Vitamin C
For most people, the best starting point is a varied diet rather than reaching straight for tablets. Useful food sources include:
- Oranges and orange juice
- Peppers
- Strawberries
- Blackcurrants
- Broccoli
- Brussels sprouts
- Potatoes
Simple meal idea
Pair beans or lentils with peppers, broccoli or citrus. That is useful because vitamin C can help the body absorb non-haem iron from plant foods.
Food first vs supplements
Supplements can be useful in specific situations, but they are not automatically better than food. Food also brings protein, fibre, fats, carbohydrates and other micronutrients that work together. A supplement is a tool, not a cheat code.
Consider a supplement if you have been advised to do so, have a restricted diet, have a confirmed deficiency, or fall into a group with higher needs. For symptoms such as ongoing tiredness, weakness, unusual bleeding, tingling, dizziness or unexplained changes, get proper medical advice rather than guessing.
Who may need to pay closer attention?
- People with restricted diets, including vegan or very limited diets.
- People who are pregnant, planning pregnancy or breastfeeding.
- Older adults or people with reduced appetite.
- People with digestive conditions, absorption issues or relevant medication use.
- Anyone with symptoms that could suggest deficiency.
When to be cautious
Large amounts of vitamin C supplements can cause stomach pain, diarrhoea and wind. Food first is the sensible default.
