Zahler Vitamin C 1000mg Tablets with Bioflavonoids - High Potency, Gentle on the Stomach, Gluten-free - 90 Tablets

Key Benefits of Vitamin C

Vitamin C is an essential nutrient that contributes to the normal function of the immune system, normal collagen formation for healthy skin and connective tissues, and the protection of cells from oxidative stress. It also increases iron absorption from plant-based foods, making it particularly valuable for vegetarians and vegans. This water-soluble vitamin supports energy metabolism and overall vitality, helping you stay resilient against everyday stressors.

Zahler's Vitamin C tablets deliver 1000 mg per serving in a buffered, non-acidic form that is gentle on the stomach. The addition of citrus bioflavonoids enhances absorption and provides extra antioxidant support, working synergistically to maximise the protective benefits.

What Makes Zahler Vitamin C with Bioflavonoids Special?

Not all vitamin C supplements are created equal. What sets Zahler apart is its thoughtful formulation designed for maximum efficacy and comfort. Each tablet provides 1000 mg of vitamin C as calcium ascorbate, a buffered form that is gentle on the stomach even at high doses. This is a game-changer for anyone who has experienced acid reflux or stomach upset from traditional ascorbic acid.

The formula includes 200 mg of PureWay-C, a proprietary blend of citrus bioflavonoid peel powder. Bioflavonoids are known to improve the absorption and bioavailability of vitamin C, meaning your body can utilise more of what you take. They also offer additional antioxidant benefits, working in synergy with vitamin C to protect your cells. Plus, these tablets are vegetarian, kosher, non-GMO, and free from common allergens like gluten, dairy, soya, and nuts—crafted in GMP-certified facilities in the USA.

Types of Vitamin C Supplements

Vitamin C supplements come in several forms, each with distinct characteristics. Ascorbic acid is the most common and cost-effective, but can be harsh on the stomach for some individuals. Buffered forms such as sodium ascorbate and calcium ascorbate are less acidic, making them a better choice for sensitive stomachs. Liposomal vitamin C offers enhanced cellular absorption, whilst it tends to be more expensive.

Whole-food sources like acerola cherry or camu camu provide vitamin C alongside other phytonutrients, but the dosage is often lower. Zahler's tablets uses calcium ascorbate, combining a high-potency dose with a gentle, non-acidic delivery. The inclusion of bioflavonoids further elevates this formula, as these natural compounds help your body process vitamin C more efficiently. When choosing a supplement, consider your tolerance, dosage needs, and any dietary restrictions—Zahler meets a wide range of preferences with its clean, allergen-free profile.

Recommended Dosage and Safety

The recommended dosage for adults is one tablet daily, providing 1000 mg of vitamin C. This amount is well within the safe upper limit of 2000 mg per day for most adults, making it suitable for long-term uses. However, individual needs may vary based on diet, lifestyle, and health status. If you have a history of kidney stones or are on certain medications, consult your doctor before starting any supplement.

Vitamin C is water-soluble, meaning excess amounts are typically excreted in urine, reducing the risk of toxicity. Still, taking more than the recommended dose may cause digestive upset or diarrhoea, especially with ascorbic acid. Thanks to the buffered calcium ascorbate in this formula, such side effects are less likely. Store in a cool, dry place and keep out of reach of children. Food supplements should not be used as a substitute for a varied diet. Always read the label and follow directions for uses.

What Is Vitamin C and Why Do You Need It?

Vitamin C is an essential nutrient your body cannot produce on its own. It contributes to the normal function of the immune system, collagen synthesis for healthy skin and joints, and protection of cells from oxidative stress. Whether you're looking to support your natural defences during cold and flu season or maintain overall wellness year-round, a high-quality vitamin C supplement like Zahler Vitamin C 1000mg Tablets with Bioflavonoids can help fill the gap when your diet falls short.

This potent formula delivers 1000 mg of vitamin C per serving in a gentle, buffered form that is easy on the stomach. Unlike standard ascorbic acid, which can cause digestive discomfort for some, this supplement uses calcium ascorbate—a non-acidic alternative that provides the same immune-supporting benefits without the irritation. Combined with citrus bioflavonoids for enhanced absorption, it is designed for daily uses by both women and men.
