Key Benefits of Vitamin C

Vitamin C is well known for its role in supporting a healthy immune system. Research suggests that adequate intake may help maintain your body's natural defences. As an antioxidant, vitamin C helps protect cells from damage by free radicals—unstable molecules that can contribute to aging and various health concerns. Additionally, vitamin C is involved in collagen synthesis, which supports the structure of skin, blood vessels, and connective tissues. While individual results vary, making vitamin C part of your daily routine is a simple step towards overall wellness.

Why Choose Prolonged Release Tablets?

Unlike immediate-release vitamin C supplements, prolonged release formulations release the nutrient slowly over several hours. This helps maintain more consistent levels in the body compared to a single large dose that is quickly excreted. For those who prefer steady support throughout the day, this extended release tablet is a convenient choice. 21st Century's formula is designed to provide sustained release, so you can benefit from vitamin C's support over a longer period.

What Is Vitamin C and Why Do You Need It?

Vitamin C, also called ascorbic acid, is a water-soluble nutrient essential for overall health. It acts as an antioxidant, neutralizing free radicals that cause oxidative stress. Your body also needs it for proper immune function and to maintain healthy bones, cartilage, teeth, and gums. Because humans cannot produce vitamin C, it must come from diet or supplements. This 500 mg prolonged release tablet from 21st Century provides a steady supply throughout the day.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, consider dosage, form, and additional ingredients. Each tablet provides 500 mg—a moderate dose suitable for daily maintenance. The prolonged release form is ideal for consistent support without multiple doses. This product contains No added sugar, salt, yeast, preservatives, artificial colour, or flavour, making it a clean option for health-conscious individuals. With 110 tablets per bottle, you have a generous supply. Always follow the recommended dosage and consult a healthcare professional if you have concerns.

Frequently Asked Questions

Can I take this on an empty stomach? Vitamin C is generally well tolerated, but taking it with food may reduce the risk of stomach upset. The prolonged release design may also help minimize digestive discomfort.

How long does one bottle last? At one tablet daily, 110 tablets provide approximately 3.5 months of supply.

Is this product suitable for vegetarians? The tablets are made without animal-derived ingredients, but check the label for specific certifications.

Can I take more than one tablet per day? Stick to the recommended dosage. If you feel you need more, consult a healthcare practitioner.
