Now Vitamin C-1000 Sustained Release, 250 Tablets

How Sustained Release Technology Works

The sustained release formula in NOW Vitamin C-1000 uses an advanced time-release matrix that controls the rate at which vitamin C is released into your digestive system. When you swallow the tablet, the outer layer begins to dissolve, delivering an initial dose. Over the next several hours, the inner matrix gradually breaks down, providing a steady trickle of vitamin C. This method mimics a continuous infusion, helping to maintain optimal blood levels for longer periods compared to immediate-release tablets.

One of the major advantages of this technology is improved gastrointestinal tolerance. High doses of vitamin C, particularly ascorbic acid, can cause stomach upset, cramping, or diarrhoea in sensitive individuals. By releg the nutrient slowly, the sustained format reduces the concentration of acid in the gut at any given time, minimising irritation while still delivering the full 1,000 mg dose. This makes it an excellent choice for those who want high-potency vitamin C without the discomfort.

Key Benefits of Vitamin C

Vitamin C is renowned for its wide range of health benefits, many of which are supported by decades of scientific research. As a potent antioxidant, it helps neutralise free radicals—unstable molecules that can damage cells and contribute to premature ageing. By reducing oxidative stress, vitamin C supports healthy ageing and cellular integrity. Additionally, it plays a vital role in immune function by encouraging the production and activity of white blood cells, which defend the body against pathogens.

Beyond immunity, vitamin C is essential for collagen synthesis, a protein that provides structure to skin, bones, tendons, and ligaments. Adequate vitamin C intake contributes to healthy skin elasticity and wound healing. The nutrient also enhances the absorption of non-haem iron from plant-based foods, supporting overall iron status and energy levels. Furthermore, research suggests that vitamin C may promote cardiovascular health by supporting blood vessel function and maintaining healthy cholesterol levels already within the normal range.

With 1,000 mg per tablet, NOW Foods Vitamin C-1000 Sustained Release delivers a potent dose of this vital nutrient. The sustained release design ensures that these benefits are spread throughout the day, providing long-lasting support without the need for multiple doses.

What Is Vitamin C and Why Do You Need It?

Vitamin C is an essential water-soluble nutrient that plays a critical role in maintaining overall health. Unlike some animals, the human body cannot produce vitamin C on its own, making dietary intake or supplementation necessary. This powerful antioxidant supports numerous bodily functions, including immune defence, collagen synthesis, and protection against oxidative stress. However, because vitamin C is water-soluble, it is quickly excreted, which is why a sustained release formula can be beneficial. By delivering the nutrient gradually over several hours, sustained release technology helps maintain consistent levels in the bloodstream, minimising the peaks and troughs associated with standard vitamin C supplements.

NOW Foods Vitamin C-1000 Sustained Release offers a convenient way to meet your daily vitamin C needs. Each tablet contains 1,000 mg of pure vitamin C in a specialised matrix designed for prolonged release. This formulation not only supports steady antioxidant activity throughout the day but also reduces the likelihood of digestive discomfort often experienced with high-dose vitamin C. Whether you are looking to bolster your immune system, support healthy skin and bones, or simply ensure adequate nutrient intake, this sustained release supplement provides a reliable solution.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, several factors can influence effectiveness and personal suitability. Form: Vitamin C is available as ascorbic acid (the most common and cost-effective form), sodium ascorbate (buffered for gentleness), and liposomal forms (designed for enhanced absorption). Ascorbic acid is well-absorbed and ideal for most people, especially when formulated as sustained release. Dosage: A 1,000 mg dosage is considered high potency and sufficient for supporting immune function and antioxidant protection. For those with higher needs, such as smokers or individuals under significant stress, split dosage or sustained release can help maintain consistent levels. Additional Ingredients: Some products include bioflavonoids or rose hips, which may enhance absorption. This NOW formula is pure vitamin C with no unnecessary additives. Quality Certifications: NOW Foods is a trusted brand known for commitment to quality, including GMP certification and third-party testing. Choosing a reputable manufacturer ensures purity and potency.

Recommended Dosage and Safety

The recommended dosage for NOW Foods Vitamin C-1000 Sustained Release is one tablet daily, preferably taken with a meal to enhance absorption and further reduce any potential gastric upset. Each bottle contains 250 tablets, providing over eight months of supplementation at this serving size. Vitamin C is generally safe even at high doses, but excessive intake (above 2,000 mg per day from supplements) may cause digestive issues in some individuals. This product's sustained release design supports tolerance at the 1,000 mg level. As with any dietary supplement, it is advisable to consult your health care provider before starting a new regimen, especially if you have existing health conditions or are taking medications. Note that vitamin C can increase iron absorption, which may be a consideration for those with iron overload disorders.

Frequently Asked Questions

Can I take this on an empty stomach? While the sustained release formula is designed to be gentle, taking it with food can help minimise the rare chance of stomach irritation. Food also aids in absorption.

Is this product suitable for vegetarians or vegans? The product is labelled as suitable for vegetarians. However, if you follow a strict vegan diet, check the label for any animal-derived ingredients. Typically, tablets may contain small amounts of silicon dioxide or stearic acid, which are generally vegan.

How does this compare to liposomal vitamin C? Liposomal forms encapsulate vitamin C in fat-like membranes to potentially enhance absorption, but they are often more expensive. This sustained release tablet offers excellent absorption at a more economical price point, and the gradual release helps maintain blood levels comparably.

Can I take more than one tablet daily? One tablet provides 1,000 mg, which is a standard high-dose. If you wish to increase intake, consult your health care provider first, and consider splitting doses for optimal tolerance.
