Esterol Ester C – Buffered Vitamin C with Bioflavonoids & Quercetin – 200 Capsules

Description
Additional Information

Key Benefits of Vitamin C

Discover Allergy Research Group — Vitamin C is widely recognized for its role in immune function. It helps support the body’s natural defences and may help maintain healthy bones, cartilage, teeth, and gums. As an antioxidant, it helps neutralize free radicals that can cause oxidative stress. The bioflavonoid complex in Esterol Ester C—including quercetin—provides additional antioxidant support and may contribute to tissue integrity and seasonal wellness. This combination makes it a comprehensive choice for those seeking to bolster their daily nutrient intake.

What Makes Esterol Ester C Different?

Unlike standard ascorbic acid, Esterol Ester C uses calcium ascorbate, a buffered form of vitamin C that is less acidic and often better tolerated. This form has been studied for improved cellular uptake and reduced gastrointestinal discomfort. The inclusion of quercetin, rutin, and grape seed extract sets this formula apart. These bioflavonoids are known for their own antioxidant properties and may work synergistically with vitamin C to support vascular health and immune resilience. The product is vegetarian-friendly and free from common allergens.

Types of Vitamin C Supplements

Vitamin C supplements come in various forms: ascorbic acid, sodium ascorbate, calcium ascorbate (as in this formula), liposomal, and whole-food sources. Ascorbic acid is the most common but can be harsh on the stomach. Buffered forms like calcium ascorbate are gentler and may offer better absorption. Liposomal vitamin C uses fat-encapsulated delivery for enhanced bioavailability. Esterol Ester C provides a well-researched, buffered option that balances potency and tolerability.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, consider dosage, form, and additional ingredients. A high-potency formula like Esterol Ester C delivers 1.35 g per serving, suitable for those with higher needs. Look for buffered forms if you have a sensitive stomach. Certifications such as vegetarian, non-GMO, and gluten-free are important for many users. Allergy Research Group has a reputation for quality, with over 45 years of experience in the supplement industry.

What Is Vitamin C and Why Do You Need It?

Vitamin C is an essential nutrient that the body cannot produce on its own. It must be obtained through diet or supplementation. This water-soluble vitamin plays a vital role in numerous physiological processes, from supporting the immune system to acting as a potent antioxidant. Allergy Research Group Esterol Ester C delivers 1.35 g of vitamin C per serving in a buffered, non-acidic form. This makes it a gentle option for those with sensitive stomachs while still providing a high-potency dose. The addition of bioflavonoids such as quercetin, rutin, and grape seed extract further enhances its antioxidant profile.

Recommended Dosage and Safety

The recommended serving size for Esterol Ester C is one capsule, providing 1.35 g of vitamin C. As with any supplement, it is best to follow the suggested use on the label. Vitamin C is water-soluble and generally safe, but high doses may cause digestive upset in some individuals. If you are pregnant or breastfeeding, consult a health-care practitioner prior to use. Keep out of reach of children. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, , or prevent any disease.
