What Makes the Prolonged Release Formula Special?

Standard vitamin C tablets release all their dose at once, causing a quick spike then a drop in blood levels. These tablets use prolonged release technology to trickle out the nutrient over hours, giving your body a more consistent supply. This means you can take just one tablet a day and still enjoy steady support, without needing multiple doses.

Looking to give your immune system a steady boost throughout the day? 21st Century's prolonged release Vitamin C tablets are designed to do just that. Each tablet delivers 1000 mg of ascorbic acid, a well-absorbed form of vitamin C, slowly and steadily.

Key Benefits of This Prolonged Release Vitamin C

This supplement offers several advantages for your daily well-being routine:

  • Immune support: Vitamin C helps support your body's natural defences and immune function.
  • Antioxidant protection: As an antioxidant, it helps shield your cells from oxidative damage caused by free radicals.
  • Convenient dosing: One tablet a day provides prolonged release of vitamin C over an extended period.
  • Clean formula: Non-GMO, gluten free, and vegan, making it suitable for a wide range of diets.

21st Century is a trusted brand with over 30 years of experience making high-quality vitamins and supplements.

How to Choose the Best Vitamin C Supplement

When picking a vitamin C supplement, consider dose, form, and certifications. Ascorbic acid is the most common and cost-effective form, and 1000 mg is a popular dose for daily maintenance. Prolonged release formulae offer convenience if you prefer once-daily dosing.

Look for products that align with your values: this supplement is non-GMO, gluten free, and vegan, making it a great choice if you have dietary restrictions. 21st Century ensures quality through careful manufacturing.

What Is Vitamin C and Why Do You Need It?

Vitamin C is an essential nutrient your body can't make on its own. It plays a key role in supporting immune function and acts as a powerful antioxidant, helping protect cells from oxidative stress caused by free radicals. Many people turn to vitamin C supplements to maintain their natural defences, especially during seasonal changes or times of stress.

With 1000 mg per serving, this supplement provides a significant dose to help meet your daily needs. The prolonged release formula is designed to deliver the nutrient slowly throughout the day, which may help maintain steady levels.

Recommended Dosage and Safety

Take one tablet daily with a meal, or as directed by your health care professional. Do not exceed the recommended dose. Vitamin C is generally well tolerated, but high doses may cause digestive upset in some people. The prolonged release design may help reduce this risk by spreading absorption over time.

Consult your health care professional before use if you are pregnant, nursing, taking medications, or have a medical condition. Keep out of reach of children and store in a cool, dry place.

Always read the label and follow directions for use.
