Why Choose Prolonged Release Tablets?

Prolonged release tablets deliver vitamin C steadily over several hours, helping to maintain consistent levels in the body. This is particularly beneficial for those who prefer a single daily dose rather than taking multiple tablets. 21st Century's 500 mg formulation use a sustained-release technology to provide ongoing support throughout the day, making it a practicable option for busy individuals.

Key Benefits of Vitamin C

Vitamin C contributes to the normal function of the immune system, as recognised by EFSA. It also plays a role in the protection of cells from oxidative stress and aids in the normal collagen formation for the normal function of skin, bones, cartilage, gums, and teeth. As an essential nutrient that the body cannot produce on its own, it must be obtained from diet or supplementation. Regular intake of vitamin C can help maintain overall wellness, whilst individual results may vary.

What Is Vitamin C and Why Do You Need It?

Also known as ascorbic acid, vitamin C is a water-soluble vitamin with antioxidant properties. It helps neutralise free radicals, which are unstable molecules that can cause cellular damage over time. The body requires vitamin C for various functions, including immune defence, collagen synthesis, and iron absorption. Since it is not stored in large amounts, a consistent supply is important. This prolonged release tablet offers a convenient way to meet your daily needs.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, consider the dosage, form, and purity. This product provides 500 mg per tablet, a moderate dose suitable for daily maintenance. The prolonged release form ensures gradual absorption, reducing the likelihood of stomach upset. It contains no added sugar, salt, yeast, preservatives, artificial flavours, or colours, making it a clean option. Each bottle contains 110 tablets, providing over three months of supply at one tablet per day. As with any supplement, always read the label and follow the directions for use.
