What Does Vitamin C Do When Sick?
Vitamin C is a powerful antioxidant that plays a crucial role in maintaining our overall health and immune system. When we’re sick, our body needs extra help to fight off the infection and restore its normal functioning. In this article, we’ll explore what vitamin C does when we’re sick and provide evidence-based information to support its benefits.
Vitamin C is an essential nutrient that supports immune function, particularly in times of illness. Here are some ways vitamin C helps:
- Boosts antioxidant defenses: Vitamin C helps protect our cells from oxidative stress, which occurs when free radicals damage our cells. Antioxidants neutralize free radicals, allowing our cells to function properly.
- Enhances inflammation reduction: Vitamin C has anti-inflammatory properties, which can help reduce inflammation caused by illness. Chronic inflammation can lead to chronic diseases, such as arthritis, diabetes, and cardiovascular disease.
- Supports immune cell function: Vitamin C is necessary for the proper functioning of immune cells, such as T-cells and natural killer cells. These cells play a crucial role in fighting off infections.
Supports Respiratory Health
Vitamin C has been shown to support respiratory health, particularly when it comes to conditions like bronchitis, pneumonia, and asthma. Here are some ways vitamin C helps:
- Relieves symptoms: Vitamin C supplements have been shown to relieve symptoms of respiratory infections, such as congestion, coughing, and fatigue.
- Reduces inflammation: Vitamin C has anti-inflammatory properties, which can help reduce inflammation in the lungs and airways, making it easier to breathe.
- Boosts lung function: Vitamin C has been shown to improve lung function in patients with emphysema and chronic obstructive pulmonary disease (COPD).
Supports Gastrointestinal Health
Vitamin C is also important for maintaining healthy gut bacteria, which is essential for gut health and immune function. Here are some ways vitamin C helps:
- Supports gut health: Vitamin C helps maintain the integrity of the gut lining, preventing leaks and reducing inflammation.
- Enhances nutrient absorption: Vitamin C is necessary for the absorption of nutrients, such as iron and vitamin B12, from the gut.
- Reduces inflammation in the gut: Vitamin C has anti-inflammatory properties, which can help reduce inflammation in the gut and alleviate symptoms of conditions like irritable bowel syndrome (IBS).
Other Benefits
Vitamin C has numerous other benefits, including:
- Antioxidant properties: Vitamin C has antioxidant properties, which can help protect our cells from damage caused by free radicals.
- Supports collagen production: Vitamin C is necessary for the production of collagen, a protein that gives structure to our skin, bones, and connective tissue.
- May help reduce cancer risk: Some studies have suggested that vitamin C may help reduce the risk of certain types of cancer, such as prostate cancer and breast cancer.
Who Can Benefit from Vitamin C Supplementation?
While vitamin C is beneficial for everyone, some groups may be more susceptible to its benefits, including:
- Infants and children: Vitamin C is essential for growth and development, and deficiencies can lead to scurvy, a disease characterized by fatigue, weakness, and bleeding gums.
- Pregnant and breastfeeding women: Vitamin C is important for fetal development and milk production, and excessive intake can lead to toxicity.
- Older adults: As we age, our body’s ability to absorb vitamin C decreases, making it essential for older adults to consume sufficient amounts through supplements or fortified foods.
Recommended Daily Intake
The recommended daily intake of vitamin C varies by age and sex, but a general guideline is:
- Adults: 90 milligrams (mg) per day for adult men and 75 mg per day for adult women.
- Pregnant and breastfeeding women: 80-85 mg per day.
- Infants and children: 40-60 mg per day.
Conclusion
Vitamin C is a powerful antioxidant that plays a crucial role in maintaining our overall health and immune system. When we’re sick, our body needs extra help to fight off the infection and restore its normal functioning. By incorporating vitamin C supplements or foods rich in vitamin C into our diet, we can support our immune function, respiratory health, and overall well-being.
