Key Benefits of This Prolonged Release Vitamin C

Each tablet provides 1000 mg of ascorbic acid, a highly absorbable form of vitamin C. This supplement supports your daily wellness in several ways:

  • Immune support: Vitamin C helps maintain the normal function of the immune system.
  • Antioxidant protection: As an antioxidant, vitamin C helps protect cells from oxidative stress.
  • Convenient dosing: Just one tablet per day provides a prolonged release of vitamin C over several hours.
  • Clean formula: Non-GMO, gluten-free, and vegan, suitable for various dietary needs.

This product is manufactured by 21st Century, a trusted brand with over 30 years of experience in the vitamin industry.

Recommended Dosage and Safety

The recommended dose is one tablet daily, taken with a meal or as directed by your healthcare practitioner. Do not exceed this dosage. Vitamin C is generally well tolerated; however, high intakes may cause gastrointestinal discomfort in some people. The prolonged release formulation may mitigate this by distributing absorption over time. If you are pregnant, nursing, taking medication, or have a health condition, consult a healthcare provider before use. Keep out of the reach of children and store in a cool, dry location. This product is a natural health product. It is not intended to diagnose, treat, , or prevent any disease.

What Makes the Prolonged Release Formula Special?

Unlike standard vitamin C tablets that release their entire dose immediately, this prolonged release formula is designed to release vitamin C gradually over several hours. This helps maintain more consistent levels in your body throughout the day. It is an excellent option for individuals who want the convenience of once-daily dosing without needing to take multiple pills.

What Is Vitamin C and Why Do You Need It?

Vitamin C is a vital nutrient that your body cannot synthesise. It plays a key role in immune health and acts as an antioxidant to protect cells from free radical damage. Many people turn to supplementation to support their natural defences, particularly during cold and flu season or times of stress. This formula delivers 1000 mg of vitamin C per tablet in a prolonged release form to help maintain optimal levels all day.

How to Choose the Best Vitamin C Supplement

When choosing a vitamin C supplement, look at the dosage, form, and certifications. Ascorbic acid is a well-absorbed form, and 1000 mg is a standard daily dose. The prolonged release feature adds convenience. This product is non-GMO, gluten-free, and vegan, making it suitable for many dietary preferences. 21st Century is committed to quality manufacturing.
