Understanding Prolonged Release Technology

The 21st Century C-1000 supplement features a prolonged release tablet design. Unlike immediate release formulas that release all the vitamin C at once, prolonged release tablets are formulated to gradually release the nutrient over several hours. This design helps maintain more consistent blood levels of vitamin C throughout the day, reducing the peaks and troughs associated with standard tablets. For those who prefer a single daily dose, a prolonged release format offers convenience without compromising on sustained nutrient availability.

Key Benefits of Vitamin C

Vitamin C is widely recognized for its role in supporting the immune system. It helps stimulate the production and function of white blood cells, which are essential for defending the body against infections. As an antioxidant, vitamin C helps neutralize free radicals, reducing oxidative stress that can contribute to chronic conditions. It also plays a key role in collagen synthesis, which is necessary for wound healing, healthy skin, and strong connective tissues. Additionally, vitamin C enhances the absorption of non-heme iron from plant-based foods, which can help maintain healthy iron levels.

What Is Vitamin C and Why Do You Need It?

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a vital role in maintaining overall health. It acts as a powerful antioxidant, helping to protect cells from damage caused by free radicals. Additionally, vitamin C supports the immune system and contributes to the normal formation of collagen for healthy skin, bones, and blood vessels. Since the body cannot produce vitamin C on its own, it must be obtained through diet or supplementation. A daily vitamin C supplement can help fill nutritional gaps, especially when dietary intake may be insufficient.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, consider factors such as dosage, form, and release profile. The C-1000 provides a moderate 1000 mg per tablet, which is suitable for daily maintenance. Tablets are a convenient and stable form, easy to store and handle. Prolonged release options are ideal for those seeking steady intake without multiple doses. Look for supplements manufactured under good manufacturing practises (GMP) to ensure quality and purity. 21st Century products are produced under established standards for dietary supplements.

Recommended Dosage and Safety

For adults, take one tablet daily with food, or as directed by a healthcare professional. Do not exceed the recommended dosage. Vitamin C is generally well tolerated, but high doses may cause digestive discomfort in some individuals. Prolonged release formats may help minimize such effects. As with any supplement, consult a health-care practitioner prior to use, especially if you are pregnant, breastfeeding, or have a medical condition. Keep out of reach of children. Store in a cool, dry place.

Frequently Asked Questions

What is the difference between prolonged release and immediate release vitamin C?

Prolonged release tablets are designed to release vitamin C gradually over several hours, providing a steady supply. Immediate release tablets release the nutrient all at once, leading to a rapid spike in blood levels followed by a decline.

Can I take this supplement on an empty stomach?

While vitamin C can be taken on an empty stomach, taking it with food may help reduce the risk of stomach upset. The prolonged release format may also be gentler on the digestive system.

How long does one bottle last?

With 110 tablets and a recommended dose of one tablet daily, each bottle provides approximately three and a half months of supplementation.
