American Health Ester-C 500 with Citrus Bioflavonoids, 90 Caplets

What Makes Ester-C Different?

If you're looking for a vitamin C supplement that's kind to your stomach and provides enduring support, Ester-C is an excellent choice. This patented form of vitamin C uses calcium ascorbate instead of ascorbic acid, making it pH-neutral and non-acidic—ideal for those with sensitive digestion. Its unique composition includes vitamin C metabolites that may enhance cellular retention and provide longer-lasting immune benefits. Clinical studies suggest that Ester-C is absorbed efficiently and remains in the body for longer than equivalent amounts of ascorbic acid. Combined with a citrus bioflavonoid complex containing hesperidin and rutin, this supplement offers synergistic antioxidant protection and supports healthy circulation. The result is a premium, once-daily vitamin C formula that delivers 24-hour immune support without the typical acidity of standard vitamin C products.

Key Benefits of Vitamin C

Vitamin C contributes to the normal function of the immune system, helping the body defend against everyday environmental challenges. It also protects cells from oxidative stress, which is important for healthy ageing. Vitamin C is necessary for normal collagen formation, supporting skin health, wound healing, and the maintenance of bones and teeth. Additionally, it enhances the absorption of non-haem iron from plant-based foods, reducing the risk of iron deficiency. The citrus bioflavonoids in this formula provide complementary benefits—they have their own antioxidant properties and may help maintain healthy capillaries and blood vessels. Together, vitamin C and bioflavonoids offer comprehensive support for overall wellness, especially during periods of seasonal stress or increased physical activity.

What Is Vitamin C and Why Do You Need It?

Vitamin C is an essential water-soluble nutrient that supports numerous functions in the body. It acts as a potent antioxidant, helping to neutralise free radicals that can damage cells. Vitamin C also plays a vital role in the immune system, encouraging the production and function of white blood cells. Moreover, it is required for the synthesis of collagen, a structural protein that supports skin elasticity, joint health, and blood vessel integrity. Because the human body cannot manufacture vitamin C, it must be obtained from diet or supplementation. While fruits and vegetables provide vitamin C, many people fall short of the recommended daily intake, making supplements a convenient way to maintain optimal levels.

Types of Vitamin C Supplements

Vitamin C supplements come in various forms, including ascorbic acid, sodium ascorbate, calcium ascorbate (Ester-C), and whole-food concentrates like acerola. Ascorbic acid is the most widely available and affordable, but its high acidity can cause stomach upset for some individuals. Sodium ascorbate is a buffered form that is less acidic but contains sodium, which may be a concern for those on low-sodium diets. Ester-C is a patented, non-acidic form that is well tolerated and often preferred for its gentle nature. Whole-food sources like acerola also provide vitamin C along with naturally occurring bioflavonoids and other phytonutrients. American Health Ester-C 500 with Citrus Bioflavonoids offers the benefits of a gentle, buffered formula combined with targeted bioflavonoids for enhanced support.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, consider factors such as form, dosage, added ingredients, and certifications. For those with sensitive stomachs, a buffered form like Ester-C or sodium ascorbate is ideal. Dosage is important; 500 mg per day is a common maintenance dose, while higher doses may be used for short-term needs. Look for supplements that include bioflavonoids, as they may improve absorption and provide additional antioxidant benefits. Vegetarian or vegan certifications are also important for those with dietary preferences. American Health Ester-C 500 is 100% vegetarian, gluten-free, and free from artificial preservatives, making it a clean and convenient choice for daily immune support.

Recommended Dosage and Safety

The recommended dosage for adults is one (1) vegetarian caplet daily, preferably with a meal. Each caplet provides 500 mg of vitamin C (as Ester-C calcium ascorbate) and 100 mg of citrus bioflavonoids. This dosage is within the safe range established by the European Food Safety Authority. Vitamin C is water-soluble, and excess amounts are excreted, but taking more than 2,000 mg per day from supplements may cause digestive discomfort. Individuals with certain conditions, such as kidney disease or haemochromatosis, should consult a health care professional before supplementing. As with all dietary supplements, it is advisable to talk to your doctor before uses, especially if you are pregnant, nursing, or taking medication.
