What Reziva Does

Is Resveratrol Really the Fountain of Youth in a Pill?

Buy Reziva

Reziva® is a unique red wine extract manufactured in France from premium red grapes, not Japanese Knotweed (Poygonum cuspidatum) as is used in other resveratrol supplements. Alcohol-free, the red grapes used in the extraction of Reziva® are abundant in polyphenols and trans-resveratrol. 

Researchers have known for years that reducing daily intake of calories dramatically slows down the aging process and extends lifespan in laboratory animals. This regimen is called calorie restriction, and it has been shown to protect mice from cancer, diabetes and other age-related diseases. It does this by producing changes in gene expression that are associated with long life.

Scientists have found recently that resveratrol, a very potent antioxidant compound found in red wine, grapes and peanuts, is able to act in a similar way without having to reduce one's intake of food.

In a study published in Cell Metabolism, mice were given resveratrol while consuming twice as many calories as normal and still lost weight. It's important to note that this research was done on mice, not humans, and further studies still need to be done to see if the results apply to humans as well.

What Does Resveratrol Do?

There are enzymes in the body called sirtuins (silent information regulator proteins) that act as protection for cells and enhance their survival. These sirtuins have been shown to increase DNA stability and speed cellular repair.

"We think sirtuins buy cells time to repair damage," says molecular biologist David Sinclair, Assistant Professor of Pathology at Harvard Medical School and co-author of the study. It is believed that the self-destruction of cancer cells, a process known as apoptosis, is activated by resveratrol.

Scientists at the University of Puerto Rico School of Medicine have found that combined levels of grape polyphenols, like those found in resveratrol supplements, provide much more potent healing power than do isolated compounds, even at much lower doses.

Reziva® brand resveratrol contains trans-resveratrol in combination with real red wine polyphenols  - without the alcohol. The intake of one Reziva®capsule daily provides as much resveratrol as 30 glasses of red wine.
