What is vitamin C?

Vitamin C is an important vitamin for overall health that boasts powerful antioxidant benefits and offers immune health support. Since your body does not naturally produce it, it’s important to eat foods rich in vitamin C like oranges, strawberries, peppers, broccoli and kale. Many of us fall short on their recommended daily intake, so it is important to take a high-quality dietary supplement.

What does vitamin C do?

Most notably, vitamin C plays a critical role in supporting healthy immune function. A vitamin C supplement helps support your immune system by protecting against oxidative stress and challenges, especially during winter months. Other vitamin C benefits include helping your body produce collagen and absorb iron, as well as supporting cardiovascular health and already-healthy blood pressure levels.

How should I take vitamin C?

Make sure to speak with your primary care doctor before incorporating a vitamin C supplement into your wellness routine. Your health care provider will determine the best formula and strength for your health and wellness goals. Follow the dosage guide on the bottle and do not to take more than what is recommended daily.

Is vitamin C good for the skin?

Vitamin C is essential for your body to naturally produce collagen. Collagen helps support skin, hair, muscles and tendons – plus it keeps your skin smooth and youthful. As you age, collagen production slows down, which can lead to wrinkles. When applied directly on the skin, vitamin C helps boost production of collagen to keep your skin firm and plump. Incorporating a topical cream that incorporates vitamin C will help your skin look smoother, youthful and help promote the overall appearance. Oral supplementation of vitamin C may benefit your skin as well.
