Vitamin C is a water-soluble nutrient with numerous functions in the body; it boosts the immune system, supports collagen production, and aids in wound healing. It also acts as an antioxidant, protecting cells from damage caused by free radicals. However, the human body cannot synthesize Vitamin C on its own. Therefore, to obtain the recommended amount, it is essential to get it from foods or nutritional supplements to maintain good health.

While Vitamin C helps lower blood pressure, it is always advised to consult a physician before using it for this specific purpose.
The Role of Vitamin C in the Body
Vitamin C, also known as ascorbic acid, is vital for the growth, development, and repair of all body tissues. According to the health website vinmec, it is involved in many bodily functions, including collagen formation, iron absorption, immune system function, wound healing, and maintaining the health of cartilage, bones, and teeth.
As an antioxidant, Vitamin C helps protect the body from damage caused by free radicals, as well as harmful chemicals and pollutants like cigarette smoke. The accumulation of free radicals can contribute to diseases such as cancer, heart disease, and arthritis.
Because the body does not store Vitamin C (excess amounts are excreted), overdosing is usually not a concern. However, it is important not to exceed the safe upper limit of 2,000 mg per day to avoid stomach upset and diarrhea. Water-soluble vitamins must be consumed regularly through the diet. It is recommended to eat fruits and vegetables rich in Vitamin C or to cook them with minimal water to preserve these vitamins.
How and When to Take Vitamin C
Vitamin C is available in various forms, such as ascorbic acid, mineral ascorbates (sodium ascorbate, calcium ascorbate), or ascorbic acid with bioflavonoids. Ascorbic acid is an excellent choice for a supplement due to its high bioavailability, meaning it is easily absorbed by the body.
The Best Time for Consumption
The ideal time to take Vitamin C is on an empty stomach. This means taking it:
In the morning.
30 minutes before a meal.
Or two hours after eating.
The body uses only the required amount and eliminates any excess through urine; therefore, it is not stored in the body. For supplements, look for products providing 45 to 120 mg, depending on age and gender.
Other Health Benefits
Vitamin C can provide health benefits by alleviating symptoms of various conditions:
Stress: A recent analytical study found Vitamin C beneficial for individuals with weakened immune systems due to stress. It is one of the nutrients most depleted by stress and is often deficient in those who consume alcohol, smoke, or deal with obesity.
Colds and Flu: While not a cure, studies suggest it can prevent serious complications like pneumonia or lung infections when taken during an illness.
Stroke: Research published in the American Journal of Clinical Nutrition found that individuals with the highest levels of Vitamin C in their blood had a 42% lower risk of stroke compared to those with the lowest levels.
Skin Aging: A study of 4,025 women (ages 40–47) showed that higher Vitamin C intake is linked to a lower likelihood of wrinkles, skin dryness, and visible signs of aging.
Rich Food Sources
Fruits and vegetables are the richest sources of Vitamin C. Since heat and light can degrade the vitamin, care should be taken during preparation. Key sources include:
Fruits: Citrus fruits, strawberries, cantaloupe, papaya, mango, raspberries, and blueberries.
Vegetables: Green peppers, tomatoes, broccoli, white and sweet potatoes, dark leafy greens, cauliflower, and cabbage.
