Vitamin C is one of the most talked-about nutrients, especially when dealing with colds and coughs. For many, it’s the go-to remedy suggested by parents or grandparents. But what exactly is Vitamin C, and why is it so essential?
What is Vitamin C?
Vitamin C, also known as ascorbic acid, is a vital nutrient that supports several bodily functions. It plays a crucial role in wound healing and iron absorption. It’s also a powerful antioxidant, helping to neutralize free radicals that can lead to serious conditions such as cancer. While some claim it boosts the immune system, there is limited scientific evidence to fully support this.
How Much Vitamin C Do You Need?
The daily requirement for Vitamin C varies based on age, gender, and individual circumstances. Here’s a quick guide:
- Infants (0–6 months): 40 mg
- Children (1–3 years): 15 mg
- Adult Men: 90 mg
- Adult Women: 75 mg
- Pregnant Women: 85 mg
- Breastfeeding Women: 120 mg
For general guidance, the Daily Value (DV) of Vitamin C is approximately 60 mg per day.
Can Too Much Vitamin C Be Harmful?
While Vitamin C is water-soluble and excess amounts are typically excreted, consuming too much can lead to side effects such as diarrhea, vomiting, and abdominal pain. The upper limit for adults is 2,000 mg per day.
What Happens If You Lack Vitamin C?
A deficiency in Vitamin C can lead to scurvy, a condition characterized by symptoms such as:
- Swollen, bleeding gums.
- Small red spots on the skin.
- Painful joints.
- Slow wound healing.
