Doctor's Breakthrough Formula

Dr. Paul Krawitz Develops New Resveratrol Health Formula

Dr. Paul KrawitzDr. Paul Krawitz, a High Honors graduate from the University of Michigan with medical training at New York's top medical institutions - Columbia-Presbyterian Medical Center and Mount Sinai Hospitals, founded Vitamin Science in 2001. Since then, Dr. Krawitz has become one of the country's leading experts in evidence-based nutritional treatment for vision and body health. As a board-certified physician and surgeon with membership in the Alpha Omega Alpha Medical Honor Society, Dr. Krawitz is a frequent speaker and is widely quoted for his articles and his book, Ultimate Insider's Guide to Eye Health. Below, he writes about his discovery.


One of the mysteries of aging was that the French people, despite a diet rich in fat and among the highest percentage of smokers in the world, lived longer than many of their healthier counterparts living in "healthier" countries. The differences weren't explained by genetics, better doctors, or fewer environmental toxins.

Reziva trans-resveratrol

What was suspected was that the French might be getting some benefit from their frequent drinking of wine. And then the evidence began to "pour in" – first in animal studies, and then in human studies. A compound known as resveratrol, a polyphenolic compound found abundantly in red wine and grapes, was the critical chemical in red wine with a myriad of health benefits – longer life, improved cardiac health, promotion of healthy cell replication, weight control, better glucose levels, reduced inflammation in arteries and more.

The question has become, "Not what can resveratrol do" but rather, "What can't resveratrol do?"

Companies jumped on the mountain of research and hundreds of resveratrol supplements began hitting store shelves.

Our customers have been asking for the past few years about why we hadn't offered a resveratrol product, and frankly, there wasn't (yet) shown to be any benefit to eye health. But that changed when a recent study demonstrated that Resveratrol effectively prevented new blood vessels from forming and even eliminating them once they had formed. The study, published in the July issue of the American Journal of Pathology found that resveratrol reduces the growth of abnormal new blood vessels in the eye (angiogenesis), the very process that can cause rapid vision changes due to aging. Researchers at Washington University in St. Louis found that high doses of resveratrol helps block the formation of these fragile new blood vessels in mouse retinas. When these new blood vessels grow out of control, the result can be rapid vision changes.

Now that I was intent on bringing resveratrol to our thousands of devoted customers, the question became, "How do we do it better than everyone else?"

I scoured the offerings from major manufacturers and vitamin stores, and I was shocked to discover two things:

First, the active trans-resveratrol was coming not from grapes but rather from the plant Polygonum Cuspidatum (Japanese knotweed), which is identified as a "noxious weed" by the United States Department of Agriculture and others. Why? Because trans-resveratrol is very plentiful in this plant, and the plant itself - a "noxious weed" is dirt cheap!

Secondly, to cover up the fact that trans-resveratrol is coming from Japanese Knotweed, manufacturers add various red wine grape ingredients in tiny amounts, just so that these ingredients can be listed on the label and the capsules smell of wine when the vitamin bottle is opened.

So finally, working with a leading manufacturer of naturally-derived nutritional supplements, I devised our own resveratrol product that I consider to be leaps and bounds above the offerings of others.

I am therefore proud to announce the arrival of:

Reziva®, a concentrated extract made from red wine grapes grown in the fertile valleys of southern France. The name lovingly comes from Ziva, the Slavic Goddess of Longevity.

Unlike other resveratrol supplements made using Polygonum Cuspidatum (Japanese knotweed), Reziva contains concentrated trans-resveratrol, oligomeric proanthocyanidins, anthocyanins and wine polyphenols - just like real red wine. In other words, Reziva is concentrated red wine – but without the alcohol! And taking only one Reziva®capsule per day gives you as much resveratrol as 30 glasses of red wine!

Like all of our products, Vitamin Science independently tests every lot of every one of our supplements for potency and purity so that you are sure that you are getting the necessary nutrients.
