Vitamin C, also known as ascorbic acid, plays a vital role in maintaining good health. It boosts immunity, improves iron absorption, and promotes healthy skin.

In a country like India, where seasonal changes often bring viral infections and health challenges, a Vitamin C-rich diet can be your natural shield. Fortunately, our diverse Indian kitchen is full of fruits and vegetables that are excellent sources of this essential nutrient.

From juicy amla to tangy oranges, adding Vitamin C to your daily meals is both easy and delicious.

In this blog, we’ll explore the top foods rich in Vitamin C, why they matter, and how you can incorporate them into your everyday meals.

Why Your Body Needs Vitamin C?

Vitamin C is essential for strengthening the immune system and protecting the body against common infections. It helps in the production of collagen, which is important for healthy skin, bones, and blood vessels.

Additionally, Vitamin C enhances iron absorption from plant-based foods, preventing anaemia and boosting energy levels. Let’s know more about it.

Essential role in immune function

Vitamin C is crucial for your immune system’s proper functioning. It supports various cellular functions of both the innate and adaptive immune systems. It helps stimulate the production and function of white blood cells, particularly neutrophils, lymphocytes, and phagocytes, which protect your body against infections.

Regular consumption of vitamin C can help reduce the severity and duration of common colds and respiratory infections. The NHS recognises vitamin C as an important nutrient for maintaining a healthy immune response, especially during winter months when colds and flu are more prevalent in the UK.

Importance of Vitamin C for collagen production and wound healing

Vitamin C is essential for synthesising collagen, the most abundant protein in your body. Collagen provides structure to your skin, bones, cartilage, tendons, and blood vessels.

Without adequate vitamin C, collagen production becomes impaired, leading to poor wound healing and structural weaknesses throughout the body. This explains why proper vitamin C intake helps wounds heal faster and supports overall skin health.

Antioxidant properties that fight free radicals

As a powerful antioxidant, vitamin C helps protect your cells against damage from free radicals—unstable molecules produced when your body breaks down food or is exposed to tobacco smoke, pollution, and ultraviolet rays from sunlight.

These free radicals contribute to ageing and various health problems, including heart disease and cancer. Vitamin C neutralises these harmful molecules, potentially reducing oxidative stress and inflammation. In Britain’s often-polluted urban environments, this protective function becomes especially valuable.

Connection to iron absorption

Vitamin C significantly enhances the absorption of non-haem iron (the type found in plant foods) by converting it to a more easily absorbed form. This is particularly important for vegetarians, vegans, and those with iron-deficiency anaemia.

Combining vitamin C-rich foods with iron-rich plant foods (like spinach, lentils, and fortified cereals) can boost iron absorption by up to threefold. This pairing helps maintain healthy iron levels, especially for women of childbearing age who have higher iron requirements.

Lesser-Known Foods Rich in Vitamin C

Some of these you may know and not. But, apart from the regular ingredients and consumed foods, these are some of the other best foods rich in Vitamin C.

Herbs and spices with significant vitamin C (Thyme, Parsley)

Many people don’t realise that common herbs and spices contain impressive amounts of vitamin C. Fresh thyme is particularly remarkable, containing about 160mg per 100g—higher than oranges! While you wouldn’t consume large quantities, even small amounts in cooking contribute meaningfully to your daily intake.

Fresh parsley provides about 133mg per 100g and adds nutritional value to many dishes. Other vitamin C-rich herbs include basil (18mg per 100g), chives (58mg per 100g), and coriander/cilantro (27mg per 100g).

Growing these herbs on a windowsill or in a small garden provides year-round access to fresh vitamin C sources. Using herbs generously in cooking, particularly adding them at the end of cooking or as garnishes, preserves more of their vitamin C content since the vitamin is heat-sensitive. Many everyday dishes like soups, stews, and roasted meats can benefit nutritionally from a generous addition of fresh herbs.

Fermented foods with vitamin C benefits

Fermented foods offer surprising vitamin C benefits, though this is often overlooked in discussions about nutrition.

Sauerkraut (fermented cabbage) contains significant vitamin C, with approximately 15-35mg per 100g depending on preparation methods.

Raw cabbage already contains vitamin C, and while some is lost during fermentation, the bioavailability of the remaining vitamin C may actually increase.

Kimchi combines cabbage with other vitamin C-rich ingredients like red chilli peppers, boosting its nutritional profile further. Traditional fermented foods from various cultures also retain some vitamin C, though in varying amounts.

Interestingly, kefir and some fermented dairy products may help improve vitamin C absorption when consumed alongside other vitamin C sources, creating a synergistic effect in your diet.

Fortified foodsare available in supermarkets

Many supermarkets offer numerous vitamin C-fortified options that can help boost intake, particularly valuable during seasons when fresh produce may be less varied. Many breakfast cereals are fortified with vitamin C, especially protein-enhanced varieties, and children’s cereals contain added vitamin C in varying amounts.

Fruit juices, drinks and cordials, particularly those marketed for children, often contain added vitamin C. Plant-based milk alternatives (especially those aimed at children) frequently contain added vitamin C, with some providing about 15% of daily vitamin C requirements per serving. Some fruit yoghurts and fromage frais products are also fortified with vitamin C, as are certain fruit-based baby foods and toddler snacks.

Plant-based substitutes for common vitamin C sources

As plant-based diets grow in popularity, many people are seeking alternatives to traditional vitamin C sources. Rose hips are an excellent source, containing up to 426mg per 100g—among the richest natural sources available. During autumn, foraging for rose hips is becoming increasingly popular for making vitamin C-rich syrups and teas.

Sea buckthorn berries, found along some coastlines and increasingly available as juice or supplements, contain about 400mg per 100g. Acerola cherries, available as powder or supplements in health food shops, provide approximately 1,700mg per 100g—one of the highest concentrations found in any food.

For those avoiding citrus due to allergies or medication interactions, blackcurrants provide an excellent alternative with about 200mg per 100g, significantly higher than oranges. Chilli peppers can substitute for bell peppers for those with nightshade sensitivities, offering comparable vitamin C content in smaller serving sizes.

Some innovative companies are now producing vitamin C-rich snacks from unexpected sources, such as dried seaweed crisps and sprout powders, which can be incorporated into smoothies or baking for those looking to diversify their nutrient sources beyond conventional fruits and vegetables.

Signs of vitamin C deficiency to watch for

While severe vitamin C deficiency (scurvy) is rare in modern Britain, mild deficiency can still occur, especially among elderly people, heavy smokers, those with limited food variety, and people with certain medical conditions.

Early signs include fatigue, irritability, and widespread joint and muscle pain. More noticeable symptoms develop as deficiency progresses: bleeding gums, poor wound healing, dry skin and hair, easy bruising, nosebleeds, swollen joints, and weakened tooth enamel.

Addressing even mild deficiencies through dietary changes can produce noticeable improvements in energy levels and overall well-being.

Meeting your daily requirement—about 75 mg for adult women and 90 mg for adult men—can be easily achieved through a balanced diet.

Seasonal Guide to Vitamin C

Winter sources when you need it most

Winter is when vitamin C becomes particularly crucial for immune support, yet fresh produce variety often diminishes. Fortunately, several vitamin C powerhouses are at their peak during winter months.

Citrus fruits like oranges, grapefruits, mandarins, and clementines become widely available and offer significant vitamin C content. Root vegetables become nutritional heroes—rutabagas (swedes) contain about 25mg per 100g, while sweet potatoes provide approximately 20mg per 100g.

Winter greens like kale (120mg per 100g) and Brussels sprouts (85mg per 100g) are excellent cold-weather sources of vitamin C. Winter squash varieties, including butternut and acorn, offer modest but valuable amounts of vitamin C—around 10-15mg per 100g.

Many winter fruits like persimmons (66mg per 100g) and kiwi fruits (93mg per 100g) are also excellent sources that become more available during colder months.

Spring and summer bounty of vitamin C-rich foods

Spring and summer bring an abundance of fresh vitamin C sources. Strawberries peak in late spring and early summer, providing about 59mg per 100g.

Bell peppers become more affordable and available in summer, with red varieties offering an impressive 128mg per 100g. Fresh herbs flourish in summer gardens, adding not only flavor but substantial vitamin C to meals.

Summer berries like blackberries (21mg per 100g) and raspberries (26mg per 100g) contribute meaningful amounts of vitamin C. Stone fruits, including peaches (7mg per 100g) and nectarines (5mg per 100g) provide modest but valuable vitamin C when consumed regularly.

Fresh tomatoes reach their flavorful peak in summer, offering about 14mg per 100g. Green vegetables like broccoli (89mg per 100g) and leafy greens grow abundantly during warmer months, ensuring plentiful vitamin C access.

Tips for preserving seasonal produce for year-round benefits

Freezing is one of the best methods for preserving vitamin C content in seasonal produce. Most berries, bell peppers, broccoli, and leafy greens can be frozen with minimal nutrient loss. For best results, freeze produce at peak ripeness after blanching the vegetables to preserve colour and nutrient content.

Dehydrating fruits and vegetables can preserve some vitamin C, though there will be more loss than with freezing. Consider making vitamin C-rich fruit leathers by pureeing and dehydrating fruits like strawberries or kiwi. Creating preserves with vitamin C-rich fruits provides a winter option, though some vitamin C is lost in the cooking process—adding lemon juice can help offset this loss.

Fermentation preserves and sometimes enhances vitamin C bioavailability. Making sauerkraut or kimchi with cabbage creates a long-lasting vitamin C source. Canning fruits and vegetables with proper techniques can retain some vitamin C, especially when processed quickly after harvest.

Tips for smoothies and juices that maximise vitamin C content

Use frozen fruits instead of ice to maintain nutrient density in smoothies. Include vitamin C-rich vegetables like spinach or kale in fruit smoothies—their flavor is masked while their nutrients are retained. Add a squeeze of lemon or lime juice to smoothies and juices just before serving to boost vitamin C content.

Consume freshly made juices immediately, as the vitamin C content decreases rapidly after exposure to air. Include the pulp when possible, as fibre helps slow the absorption of natural sugars. Combine fruits and vegetables in juices for balanced nutrition and flavours—try carrot with orange or apple with kale.

Clever food pairings to enhance Vitamin C absorption

Pair vitamin C sources with iron-rich foods like lentils, beans, or spinach to enhance iron absorption—try adding bell peppers to bean salads or lemon juice to spinach dishes. Combine vitamin C foods with healthy fats to improve absorption of fat-soluble vitamins and antioxidants—add olive oil to salads with bell peppers or avocado to berry smoothies.

Incorporate vitamin C-rich foods in meals containing zinc (like legumes or meat) to maximise zinc absorption. Add citrus or berry dressings to salads containing nuts and seeds to enhance the absorption of their nutrients. Include vitamin C foods in meals containing calcium sources for overall nutritional synergy—try broccoli with cheese or oranges alongside yoghurt.

Vitamin C Supplements: When and Why?

Some populations have higher vitamin C requirements and may benefit from supplementation. Smokers need 35mg more vitamin C daily than non-smokers due to increased oxidative stress. People with limited dietary variety, including some elderly individuals or those with food insecurities, may struggle to obtain sufficient vitamin C from the diet alone.

Individuals recovering from surgery or wounds may benefit from temporary supplementation to support collagen formation and healing. Those with certain medical conditions, including malabsorption disorders, cancer, and kidney disease receiving dialysis, may have higher needs or impaired vitamin C absorption.

People under significant physical stress, including athletes in intense training periods and individuals fighting infections, may benefit from additional vitamin C.

Tips to Maximise Your Vitamin C Intake

• Eat raw when possible: Cooking can reduce Vitamin C content by up to 50%. Light steaming is better than boiling.
• Combine with iron-rich foods: For example, add bell peppers to spinach salads to boost iron absorption.
• Snack on fresh fruits: Carry an orange or a handful of strawberries to snack on during the day.
• Make smoothies: Blend kiwi, orange, and spinach for a quick, nutritious drink.
