What Makes Ester-C Different?

Ester-C is not your average vitamin C. It's manufactured through a water-based process that neutralises pH, making it non-acidic and gentle on the stomach—a real bonus for those who experience digestive discomfort with standard ascorbic acid. Plus, Ester-C is combined with citrus bioflavonoids, naturally occurring compounds found in citrus fruits that work synergistically with vitamin C to support optimal absorption and effectiveness. This means your body can get the most out of every dose.

Key Benefits of Vitamin C

Vitamin C contributes to the normal function of the immune system and helps protect cells from oxidative stress. As an antioxidant, it fights free radicals that can damage cells over time. Research suggests that maintaining adequate vitamin C levels may help support a healthy immune response. Ester-C is a clinically studied form of vitamin C that provides 24-hour immune support with just one daily serving. Unlike regular vitamin C, Ester-C contains naturally occurring metabolites that may help enhance the retention of vitamin C in white blood cells—an important part of the immune system. This means it stays in your system up to twice as long as regular vitamin C.

What Is Vitamin C and Why Do You Need It?

Vitamin C is an essential nutrient that your body cannot produce on its own—you need to get it from diet or supplementation. Known for its powerful antioxidant properties, vitamin C plays a vital role in supporting the immune system, promoting healthy skin, and aiding in the absorption of iron. While many people turn to citrus fruits for their vitamin C, a high-quality supplement like American Health Ester-C ensures you meet your daily needs consistently. It delivers a unique form of vitamin C designed for enhanced absorption and round-the-clock immune support.

How to Choose the Best Vitamin C Supplement

When picking a vitamin C supplement, think about the form, dosage, and extra ingredients. Ester-C offers a buffered, gentle formula ideal for daily use. The inclusion of citrus bioflavonoids sets it apart from basic vitamin C. Always look for supplements that are third-party tested for purity and potency. American Health Ester-C is manufactured with strict quality standards, so you know you're getting a reliable product. With 500 mg per capsule and a recommended serving of two capsules, this bottle provides a 60-day supply.

Recommended Dosage and Safety

The recommended dosage for adults is two capsules daily, preferably with a meal. Each serving provides 1000 mg of Ester-C along with 100 mg of citrus bioflavonoids. Vitamin C is water-soluble, and excess is typically excreted, but high doses may cause digestive discomfort in some individuals. Ester-C's gentle formulation minimises this risk. As with any supplement, consult your healthcare professional before starting a new regimen, especially if you are pregnant, nursing, or have a medical condition. Store in a cool, dry place and keep out of reach of children. Always read the label and follow the directions for use.
