Key Benefits of This Vitamin C Supplement

Vitamin C plays a crucial role in supporting the body's natural defences. It contributes to the normal function of the immune system and helps protect cells from oxidative stress. Additionally, vitamin C is needed for normal collagen formation, which supports healthy skin, bones, cartilage, gums and teeth. By choosing a high-quality supplement like this one, you ensure a reliable source of this essential nutrient. Ester-C 500 mg with Citrus Bioflavonoids from American Health is formulated to deliver these advantages without the harsh acidity that can accompany other vitamin C products.

What Is Ester-C and How Is It Different?

Vitamin C is an essential nutrient that the body cannot produce on its own; it must be obtained through diet or supplementation. Ester-C is a patented form of vitamin C that is buffered and non-acidic, making it gentler on the stomach compared to standard ascorbic acid. This unique form, made from calcium ascorbate, is designed for efficient absorption. Many people find Ester-C a comfortable option for daily intake, especially those with sensitive digestions. Each serving provides 500 mg of vitamin C in the Ester-C form, complemented by citrus bioflavonoids—natural plant compounds found in citrus fruits that support the activity of vitamin C in the body.

The Role of Citrus Bioflavonoids

Citrus bioflavonoids are naturally occurring compounds from the peels and pulp of citrus fruits. They are often included with vitamin C because they may aid its absorption and utilisation. Research suggests that bioflavonoids possess their own antioxidant properties and work synergistically with vitamin C to promote overall wellness. This product contains a generous amount of citrus bioflavonoids, offering a more complete nutritional profile akin to whole food sources. For those wishing to maximise their vitamin C supplement's benefits, the addition of bioflavonoids is a valuable feature.

As a food supplement, take one or two caplets daily, preferably with a meal.

This bottle contains 120 caplets, providing a 60- to 120-day supply depending on your chosen serving size. Remember, supplements are meant to complement a balanced diet, not replace it. A healthy lifestyle with a variety of fruits and vegetables will also contribute to your overall wellbeing.

Frequently Asked Questions

Is Ester-C better than regular vitamin C?

Ester-C is a buffered, non-acidic form of vitamin C that may be easier on the stomach for some individuals. It is also thought to have enhanced absorption, whilst individual results may vary. Both forms provide the same essential nutrient, so the choice often comes down to personal preference and tolerance.

Can I take this supplement on an empty stomach?

Because Ester-C is non-acidic, it is generally well tolerated even on an empty stomach. However, if you have a particularly sensitive stomach, taking it with food may be more comfortable.

How should I store this product?

Store in a cool, dry place away from direct sunlight. Keep the caplets in their original container with the lid tightly closed. Do not use if the seal is broken.
