SAN DIMAS, California, April 22 /PRNewswire/ --

To enhance absorption, the Longevinex(R) matrix of nutraceuticals now features micron-sized trans-resveratrol, microencapsulated in an envelope of all natural plant dextrins and starches to preserve resveratrol in its trans-resveratrol form from degradation by light, heat and oxygen. (Refs 1, 2)

The newly formulated Longevinex resveratrol matrix withstands direct exposure to solar ultraviolet radiation and heat in independent laboratory tests, says Bill Sardi, spokesperson for Longevinex.

Microencapsulation protects resveratrol from environmental factors before it is encapsulated into a larger oral capsule. Microencapsulation also facilitates slow release and better absorption.

The ingredients in Longevinex(R) capsules are newly formulated to provide rice bran ferulate, and natural vitamin D3.

The ingredients in Longevinex(R) work additively and synergistically, says Sardi. Vitamin D3 works to breakdown rice bran IP6, a whole-grain factor also provided in Longevinex, into IP3, which is its primary active form. Quercetin allows more resveratrol to pass through the liver before it is metabolized, improving immediate bioavailability of resveratrol.

A drawback of most resveratrol supplements is their emodin content. Small amounts of emodin can induce loose stool in sensitive individuals. Resveratrol in Longevinex(R) is a purified form that is virtually emodin-free.

The newly formulated Longevinex(R) matrix is produced in a vege-capsule, to meet requirements of vegetarians.

Longevinex(R) provides a unique array of mineral chelators (patent applied for) based around an over-mineralization theory of aging, explained at its website.

Longevinex(R) is the first and only resveratrol-based dietary supplement to be shown to be efficacious in a human study (reduced markers of oxidation and inflammation among endurance athletes in independent study conducted by researchers at Appalachian State University).
