Vitamin C, also known as ascorbic acid, is one of the most popular and essential vitamins for maintaining overall health. It’s a powerful antioxidant that plays a critical role in various bodily functions, including supporting the immune system, improving skin health, and aiding in the absorption of iron. Here’s a closer look at why vitamin C is vital, how you can get more of it, and what happens when you don’t get enough.
1. Immune System Support
Vitamin C is well-known for its immune-boosting properties. It helps stimulate the production of white blood cells, which are vital in fighting off infections and illnesses. By enhancing immune defence, vitamin C can shorten the duration of the common cold and may even help prevent more serious illnesses.
2. Skin Health and Collagen Production
Vitamin C is a key player in collagen synthesis, the protein responsible for keeping your skin firm and youthful. Regular intake of vitamin C can promote smoother skin, reduce the appearance of wrinkles, and help heal wounds faster. Its antioxidant properties also protect skin cells from damage caused by free radicals, which contribute to premature ageing.
3. Antioxidant Protection
As a potent antioxidant, vitamin C fights oxidative stress in the body by neutralising free radicals. These free radicals are unstable molecules that can damage cells and contribute to various chronic diseases, including heart disease, cancer, and arthritis.
4. Iron Absorption
For those who consume plant-based diets, vitamin C is particularly beneficial as it enhances the absorption of non-heme iron found in plant foods like beans, lentils, and spinach. Pairing foods high in vitamin C with iron-rich meals can improve iron levels and help prevent anaemia.
5. Heart Health
Vitamin C may also promote cardiovascular health. Studies suggest that it can help reduce blood pressure, lower the risk of heart disease, and decrease LDL (bad) cholesterol and triglycerides.
Best Food Sources of Vitamin C
Unlike some vitamins, the body doesn’t produce or store vitamin C, so it’s important to get it from your diet. Some of the best sources include:
- Citrus Fruits: Oranges, lemons, grapefruits, and limes are classic sources of vitamin C.
- Berries: Strawberries, blueberries, and raspberries are packed with antioxidants, including vitamin C.
- Leafy Greens: Spinach, kale, and broccoli offer substantial vitamin C along with other nutrients.
- Peppers: Red and green bell peppers are among the richest sources of vitamin C.
- Kiwi: This tropical fruit delivers a powerful dose of vitamin C along with other beneficial nutrients.
Signs of Vitamin C Deficiency
A lack of vitamin C in the diet can lead to several health issues, the most severe being scurvy. Common symptoms of vitamin C deficiency include:
- Frequent infections
- Slow wound healing
- Fatigue and weakness
- Bleeding gums
- Dry, rough skin
Can You Get Too Much Vitamin C?
While vitamin C is water-soluble, meaning excess amounts are flushed out of the body, very high doses (above 2,000 mg per day) can cause gastrointestinal discomfort, including diarrhoea and nausea. It’s always best to get your nutrients from whole foods rather than supplements unless advised by a healthcare provider.
Vitamin C is a crucial nutrient for maintaining optimal health, supporting everything from your immune system to your skin’s appearance. Including a variety of vitamin C-rich foods in your daily diet ensures you reap all the benefits of this powerful antioxidant. So, stock up on citrus fruits, leafy greens, and colourful veggies to keep your vitamin C levels high and your body thriving!
