Vitamin C, also known as ascorbic acid, is a vital, water-soluble nutrient that supports many essential bodily functions[1]. From bolstering immune defences to enhancing skin health and providing antioxidant protection, vitamin C’s benefits extend throughout the body[2].
In this blog, we’ll cover the optimal ways to integrate vitamin C into your diet, explore the best times to take it, and offer tips on maximising its effects for overall wellness.
Key Takeaways:
- • Vitamin C is crucial for immune health, skin support, and general well-being.
- • It can be taken any time of day, with or without food, due to its water-soluble nature.
- •Staying hydrated enhances vitamin C absorption in the body.
- • Combining vitamin C with nutrients like iron, collagen, and zinc maximises its effects on skin, immunity, and more.
Best Practices for Taking Vitamin C
There are several best practices to help maximise the absorption and benefits of vitamin C. Although it’s a water-soluble vitamin, meaning the body doesn’t store it, and excess amounts are excreted[1], being mindful of timing, pairing with food, and hydration can make a difference.
Ideal Time of Day
Vitamin C’s flexibility is due to its water-soluble nature, allowing it to be absorbed at any time of the day[3]. Those taking multiple supplements or vitamins may find that spreading them out over the day, with vitamin C in the morning, can also help avoid any mild digestive discomfort associated with taking multiple nutrients at once[4].
Taking Vitamin C with or Without Food
Vitamin C can be taken with or without food, making it easy to add to your daily routine[5]. For those with sensitive stomachs, taking vitamin C alongside meals can help reduce potential gastrointestinal discomfort due to its acidity[6]. Meals also contain other nutrients, such as healthy fats, which may aid in the overall absorption of nutrients, though food is not specifically essential for vitamin C absorption.
The Role of Hydration
Vitamin C is absorbed in the small intestine and is water-soluble[9]; hydration supports efficient distribution throughout the body. Staying adequately hydrated also aids digestion and ensures water-soluble nutrients like vitamin C are utilised and transported efficiently[7]. In particular, for people with increased vitamin C needs—such as smokers or those under stress[8]—staying well-hydrated supports optimal use of this important nutrient.
Boosting Vitamin C’s Effects with Other Nutrients
Combining vitamin C with certain other nutrients can amplify its benefits, particularly for immune support, skin health, and antioxidant defence. Here’s how these nutrient pairings work:
Vitamin C and Iron
Vitamin C significantly enhances the absorption of non-heme iron, the type found in plant-based foods, by converting it into a form more readily absorbed by the body[10]. This is especially useful for those on vegetarian or vegan diets who rely on plant sources of iron. Including vitamin C-rich foods with iron sources (like spinach or lentils) can improve iron intake and reduce the risk of deficiency.
Vitamin C and Collagen
As an essential cofactor for collagen synthesis, vitamin C supports collagen’s role in promoting skin elasticity and joint health[11][12]. It helps stabilise and strengthen the collagen molecule, which is crucial for maintaining skin structure and resilience[12]. This combination is widely used in skin care products and supplements to enhance skin and joint function.
Vitamin C and Vitamin E
Vitamin C and E provide a robust antioxidant defence by recycling each other’s active forms, enhancing protection against oxidative stress[13]. This synergy is particularly beneficial for skin health, as both vitamins help reduce UV-induced damage and may contribute to a more youthful complexion[14][15].
Vitamin C and Zinc
Both vitamin C and zinc are well-known for supporting immune function[16]. Zinc plays a role in maintaining immune cell integrity, while vitamin C helps produce white blood cells essential for fighting infection[16]. Taken together, they may provide a stronger boost to the immune system, making this combination popular in immune support supplements[16][15].
Combining these nutrients can be a simple way to enhance Vitamin C’s benefits, whether through food pairings or targeted supplements.
Whole Foods vs. Supplements: Finding the Right Source of Vitamin C
Top Vitamin C-Rich Foods for Daily Intake
Incorporating vitamin C-rich foods into your diet is an excellent way to ensure adequate amounts of this essential nutrient. Here are some top choices[17]:
- • Fruits: Citrus fruits like oranges, strawberries, kiwis, and guava are high in vitamin C.
- • Vegetables: Bell peppers, broccoli, and Brussels sprouts provide substantial levels of vitamin C and can be easily incorporated into meals.
Vitamin C Supplements
While whole foods remain the best source for vitamin C intake, supplements provide a practical solution for individuals who may need extra support, such as during seasonal changes, times of illness, or when dietary sources are insufficient. Vitamin C supplements can effectively meet daily requirements and bolster immunity when natural intake is lower than recommended.
Types of Vitamin C Supplements
- • Vitamin C Tablets: Simple and effective, tablets are an easy choice for consistent daily intake.
- • Vitamin C Capsules: Similar to tablets but often preferred for easier swallowing or targeted absorption.
- • Vitamin C Powder: Flexible in dosage, powder can be mixed into water or smoothies, making it versatile for those who prefer liquid intake.
- • Chewable Vitamin C: Popular for their taste, chewables are an enjoyable way to meet vitamin C needs, especially among children and adults looking for a flavourful option.
- • Effervescent Vitamin C Tablets: Dissolve quickly in water, creating a refreshing, easy-to-digest drink.
- • Vitamin C Liquid: Easy and convenient way of taking, high in absorption.

How to Properly Store Vitamin C for Maximum Potency
Storing vitamin C correctly is essential to preserve its potency and maximise its effectiveness. Being sensitive to light, heat, and air, vitamin C can degrade if not stored properly, which reduces its nutritional benefits. Here are some guidelines for keeping your vitamin C at its best:
- 1. Store in a Cool, Dry Place: Heat can cause vitamin C to break down, so avoid storing it in warm or humid areas, like kitchens or bathrooms. Instead, keep it in a cool, dry location, such as a cupboard, away from heat sources[24].
- 2. Choose Dark or Opaque Containers: Light exposure can weaken vitamin C over time[25]. Many vitamin C supplements come in dark or opaque containers to prevent light damage. If your supplement didn’t come in such packaging, consider transferring it to a dark container to protect it better.
- 3. Keep Lids Tightly Closed: Exposure to air accelerates the degradation process of vitamin C[26]. Always ensure the container is tightly closed after each use to minimise air exposure, keeping the vitamin fresher for longer.
- 4. Avoid High-Humidity Areas: Moisture can impact the stability of vitamin C[27], particularly in powder or tablet form. Keep it away from areas prone to humidity, like the bathroom, and avoid storing it in the fridge unless specifically advised, as fluctuating temperatures can also lead to condensation inside the container.
Following these steps will help maintain the potency and effectiveness of your vitamin C supplements, ensuring you get the maximum benefit from every dose.
Dosage Recommendations and Safety
For adults aged 19 to 64, the recommended daily vitamin C intake is 40 mg[18]. Taking high doses of vitamin C (more than 1,000 mg daily) may lead to temporary side effects, including diarrhoea, stomach cramps, and bloating[18]. Keeping daily supplement intake below this amount minimises the likelihood of adverse effects. Always consult your healthcare expert to determine the right dosage based on your individual health needs and conditions.
Can You Ever Take Too Much Vitamin C?
Vitamin C is water-soluble, so any excess is generally excreted through urine, making toxic levels uncommon[19]. However, prolonged high intake can lead to certain risks, particularly for susceptible individuals. Those with hereditary hemochromatosis—a condition where iron accumulates in the body—should exercise caution, as vitamin C enhances the absorption of non-heme iron[20]. In such cases, high doses of vitamin C could worsen iron overload, potentially causing tissue damage[21]. Conversely, vitamin C can be beneficial by enhancing iron uptake for those with low iron stores or individuals supplementing with iron.
Additionally, some studies have suggested that consistently high vitamin C intake may lead to reduced levels of vitamin B12 and copper, erosion of dental enamel, or even allergic responses. However, these findings require further research for confirmation[22]. For general safety, a daily vitamin C supplement limit of 1,000 mg is recommended, which helps to avoid risks such as digestive discomfort, kidney stone formation, and potential nutrient imbalances[18].
Conclusion
Integrating vitamin C into your daily routine can be simple and highly beneficial, especially with a few best practices. Because it’s a water-soluble vitamin, vitamin C can be taken any time of day, with or without food, and pairs well with various nutrients for enhanced effects. Drinking enough water is crucial, as hydration helps vitamin C circulate and function effectively in the body. Combining it with complementary nutrients, such as iron for improved absorption, collagen for skin health, and zinc for immune support, can amplify vitamin C’s benefits.
Meeting your recommended daily intake can be achieved through a balanced diet rich in fruits and vegetables or, if needed, through supplements. Nature’s Fix offers high-quality vitamin C options from reputed brands, allowing you to support your health effectively.
