Ester C complex – 90 tablets

Ester C - the patented vitamin C with rutin, acerola, rosehips and flavonoids

The advantages of Ester C have been confirmed by many tests. The manufacturing company Intercal was granted the globally valid patent: 4.822.816. Ester C® is resorbed quickly in the gastrointestinal tract and transported into the cells. It has a high bioavailability and gets into the blood stream twice as fast.


Ester C® contains a mixture of mineral ascorbate (acid-free) and vitamin C metabolites. Both components support each other’s effect and enhance the resorption and usability of vitamin C.
This product additionally contains citrus bioflavonoids, rutin, acerola and rosehips, which work together synergistically with Ester C® and ensure a delayed resorption of the vitamin C.


A comparison between common vitamin C and Ester C® regarding the cellular absorption (uptake by the cells) showed that Ester C® promotes the transport of vitamin C into the cells and ensures a high vitamin C concentration in the cells.


Unlike ascorbic acid, Ester C® has a neutral pH value and is therefore well tolerable for sensitive persons.

Specialities of Ester C®

During intensive examinations by a group of chemists, nutritionists and pharmacologists, the presence of the naturally occurring vitamin C metabolites in Ester C® has been proven. These metabolites are intermediates in the metabolism. They also develop in the body during the metabolisation of vitamin C.
However, the amount of these important metabolites only seems to increase with the intake of very high doses of common vitamin C.
Ester C®, on the other hand, provides these important metabolites in a sufficiently high concentration. The metabolites, no matter if they are formed by the body or taken in with a vitamin C supplement such as Ester C®, are able to affect the transport and utilisation of vitamin C.
Dr. Anthony Verlangieri, professor of pharmacology and toxicology at the University of Mississippi, examined how the metabolites and vitamin C affect each other in the body. His work showed that vitamin C metabolites, mostly threonate, are directly connected with an increased vitamin C concentration in the blood. Threonate is an intracellular door opener, which allows the vitamin C to get into the cells quickly and efficiently. This makes Ester C® the only vitamin C immediately available for the body.
