Ester-C

Ester-C is a patented form of vitamin C containing calcium L-threonate and vitamin C metabolites that enhance bioavailability and cellular retention. It supports immune function through enhanced white blood cell activity and provides superior antioxidant protection compared to standard ascorbic acid.

Origin & History

Ester-C is a patented form of vitamin C that includes calcium ascorbate and metabolites, designed to enhance absorption and retention in the body.

Historical & Cultural Context

Ester-C was developed in the late 20th century as a unique form of vitamin C, offering improved absorption and retention.

Health Benefits

- Supports a strong immune system by enhancing the activity of natural killer cells, crucial for pathogen defense. - Provides antioxidant protection, reducing free radical damage by up to 50% and supporting cellular health. - Enhances skin health by promoting collagen synthesis, leading to reduced signs of aging. - Supports cardiovascular health by lowering blood pressure and improving arterial function. - Increases calcium absorption, supporting bone health and reducing the risk of osteoporosis. - Promotes brain health by protecting against oxidative stress and supporting cognitive clarity. - Supports adrenal function, helping to manage stress and improve overall energy levels.

How It Works

Ester-C contains calcium L-threonate and naturally occurring vitamin C metabolites including L-xyonate and L-lyxonate that facilitate enhanced cellular uptake through improved transporter affinity. These metabolites increase vitamin C retention in white blood cells by up to 24 hours, prolonging antioxidant activity and immune cell function. The calcium component also supports the vitamin's stability and gastric tolerance.

Scientific Research

Studies show that Ester-C is absorbed more quickly and retained longer in the body compared to traditional vitamin C, enhancing its effectiveness.

Clinical Summary

Clinical studies demonstrate Ester-C achieves higher plasma vitamin C levels and longer retention compared to ascorbic acid in human trials with 30-60 participants. Research shows 24-hour vitamin C retention in white blood cells versus 12 hours for regular vitamin C. Limited studies suggest enhanced immune cell function and reduced oxidative stress markers. However, most research comes from manufacturer-sponsored trials with relatively small sample sizes, requiring independent replication.

Nutritional Profile

- Provides vitamin C. - Contains calcium for added benefits. - Includes vitamin C metabolites for enhanced absorption.

Preparation & Dosage

Typical dosage ranges from 500-1000 mg per day. Consult a healthcare provider before use.

Synergy & Pairings

Vitamin E, CoQ10, Omega-3 fatty acids

Safety & Interactions

Ester-C is generally well-tolerated with fewer gastrointestinal side effects than ascorbic acid due to its neutral pH. Standard vitamin C precautions apply: doses above 2000mg may cause diarrhea, nausea, or kidney stones in susceptible individuals. May enhance iron absorption and interact with blood thinners, chemotherapy drugs, and certain antibiotics. Pregnant and nursing women should consult healthcare providers before supplementing above RDA levels.
