Vitamin C: The Essential Immune-Boosting Superstar for the Whole Family
Vitamin C, also known as ascorbic acid, is one of the most popular and important vitamins for supporting health in kids and adults alike. From fighting off colds to keeping skin glowing and gums healthy, vitamin C is a must-have nutrient in your daily routine. Let’s explore everything you need to know about vitamin C, including its benefits, recommended amounts, food sources, and possible side effects.
What Does Vitamin C Do?
Vitamin C is a water-soluble vitamin, which means your body doesn’t store it—so you need to get it from food or supplements every day. Here’s why it’s so important:
-
Immune Support: Helps your body fight infections and recover faster from illness.
-
Wound Healing: Essential for repairing cuts, scrapes, and bruises.
-
Collagen Production: Keeps skin, blood vessels, bones, and cartilage strong and healthy.
-
Antioxidant Power: Protects cells from damage caused by free radicals (unstable molecules that can harm your body).
-
Iron Absorption: Helps your body absorb iron from plant-based foods, preventing anemia.
-
Healthy Gums and Teeth: Keeps gums healthy and helps prevent bleeding and loose teeth.

Vitamin C needs vary by age and life stage. Here’s a handy table:
