Understanding Vitamin C Sustained Release

Vitamin C is a vital nutrient known for its role in supporting a healthy immune system and acting as an antioxidant. A sustained release formula, such as the one offered here, is designed to provide a steady release of vitamin C into the body over an extended period. This gradual delivery aims to maintain consistent nutrient levels in your system.

Features of Sustained Release Vitamin C

This product contains 500mg of vitamin C, which is released slowly over approximately 8 hours. The inclusion of mineral ascorbates helps to moderate the acidity of vitamin C, making it a gentler option for those with sensitive stomachs. Additionally, bioflavonoids are present to complement the action of vitamin C.

Benefits of a Gradual Vitamin C Supply

The slow release of vitamin C is designed to support the immune system. Antioxidants like vitamin C contribute to the protection of cells from oxidative stress. Furthermore, vitamin C is involved in the production of collagen, which is important for skin, bone, and joint health. It also plays a role in enhancing the absorption of iron from dietary sources.

Consistent levels of vitamin C throughout the day may help in maintaining general wellbeing. While vitamin C is not a cure for the common cold, adequate intake may help manage its symptoms and duration.

Considerations for Use

The product is formulated to provide a portion of the recommended daily intake of vitamin C. It is suitable for daily use to support overall health. For those experiencing a cold, the product may be used as part of a healthy lifestyle to help manage symptoms.

As Australia’s leading vitamin brand, this sustained release vitamin C supplement is crafted to meet high-quality standards. It offers a convenient way to incorporate this essential nutrient into your daily routine.
