American Health Ester-C Vitamin C with Citrus Bioflavonoids - 1000 mg, 120 Veggie Tablets

What Makes Ester-C® Different?

Discover Ester-Vitamin With Citrus — Standard vitamin C (ascorbic acid) is acidic and can cause digestive discomfort at high doses. Ester-C® is a patented form manufactured through a unique process that converts ascorbic acid into a calcium ascorbate complex, resulting in a pH-neutral supplement that is gentle on the stomach. Studies indicate that Ester-C® is absorbed more efficiently and remains in the body's tissues longer than ordinary ascorbic acid. For individuals who require higher daily doses—such as smokers or those under physical stress—Ester-C® offers a well-tolerated alternative that supports consistent nutrient levels throughout the day.

Key Benefits for Everyday Wellness

Vitamin C is an essential nutrient that contributes to the normal function of the immune system. It also acts as a potent antioxidant, helping to protect cells from oxidative stress. The addition of citrus bioflavonoids—including hesperidin and rutin—may further support the body's natural defences and promote healthy circulation. Together, these ingredients contribute to normal collagen formation for the normal function of skin, blood vessels, bones, cartilage, gums and teeth. Scientific research suggests that the combination of vitamin C and bioflavonoids can enhance the nutrient's bioavailability, meaning your body may absorb and utilise it more effectively.

How to Select a High-Quality Vitamin C

When choosing a vitamin C supplement, quality and purity matter. American Health's Ester-C® is free from gluten, yeast, wheat, milk and milk derivatives, making it suitable for individuals with common food sensitivities. It is also certified vegan and non-GMO, ensuring the product aligns with plant-based and clean-label preferences. The tablets are formulated without artificial binders or unnecessary fillers, delivering just the active ingredients you need. Look for supplements that disclose their full ingredient list and undergo third-party testing to verify potency and purity.

Recommended Dosage and Practicable Advice

The typical serving is one tablet daily, providing 1000 mg of vitamin C from Ester-C® and 100 mg of citrus bioflavonoids. This amount is well above the recommended daily intake for adults but remains within safe upper limits. As with any supplement, consult your health care provider before starting a new regimen, especially if you are pregnant, nursing or taking medication. Vitamin C is water-soluble, so excess amounts are generally excreted in urine, but extremely high doses may cause gastrointestinal discomfort in sensitive individuals. Store in a cool, dry place away from direct sunlight.
