1. Vitamin C and Skin Health


To help maintain skin health, make sure you consume enough vitamin C in your diet. As an antioxidant, vitamin C plays an important role in skin health. Antioxidants help fight free radicals to help maintain healthy skin at a cellular level. Vitamin C also helps your body create collagen.1 Collagen is a protein your body produces, which helps give your skin its firmness and elasticity. To incorporate vitamin C-rich foods into your diet, try foods like broccoli, strawberries, kale, kiwis, orange juice, and red peppers. The Recommended Dietary Allowance (RDA) for vitamin C is 90 mg/day for men and 75 mg/day for women.2

2. Vitamin C for Immune Support

Many people know that vitamin C plays a role in immune health. In fact, studies show that vitamin C helps support the cellular functions of both the innate and adaptive immune system.3 Vitamin C is a powerful antioxidant that helps keep your immune system up and running. Supporting a healthy immune system requires a variety of vitamins and nutrients—an essential one is vitamin C. Luckily, vitamin C is in a lot of common foods. To help ensure you get the daily recommended amount of vitamin C, continue to incorporate recipes with vitamin C-rich foods into the daily menu, and if you like, take Emergen-C as a complement to your healthy diet.

3. Vitamin C and Iron Absorption

Did you know there was a link between Vitamin C and iron absorption? Iron is a mineral found in meat, seafood, and spinach and is essential for growth and development. It’s an important component of hundreds of proteins and enzymes that support essential biological functions, such as oxygen transport, energy production, and DNA synthesis.4 Vitamin C increases the intestinal absorption of iron from non heme iron food sources.5 So, if you want to get more of the iron from the foods you eat, consider adding a vitamin C-rich food to your meal, like orange juice with your iron-fortified cereal, or serve a leafy green salad with your dinner entree.
