New findings indicate polyphenols from blueberry and grape extracts prevent age-related memory decline

BOSTON, July 25, 2018 /PRNewswire/ -- A newly published study in the Journals of Gerontology has found that a six-month supplementation with Neurophenol®,  a polyphenol-rich extract of blueberry and grape, improved episodic memory in healthy older adults. The potentially groundbreaking results from researchers at the Institute of Nutrition and Functional Foods (INAF) in Canada and the University of Bordeaux in France demonstrated an improvement of eight years of cognitive age in study subjects, a significant discovery in an era when an estimated 16 million people in the United States are living with, and suffering from, cognitive decline.

"In our observations, individuals with mild cognitive impairments and who performed at the level of an 83-year-old at baseline using the CANTAB battery, scored like 70-year-olds after supplementation with Neurophenol®¹," explained lead researcher Yves Desjardins. "These findings hold exciting promise for the power polyphenols can have in treating, and preventing, some age-related cognitive decline—a devastating side effect of the aging process." 

Neurophenol® is a clinically researched blend of standardized wild blueberry and grape extracts that provides a proprietary profile of polyphenols with neuroprotective properties. Researchers conducted a double-blind, randomized, placebo-controlled clinical study of 215 healthy subjects between 60 and 70 years of age to investigate the role of polyphenols in preventing age-related cognitive decline (ARCD).

Unlike Alzheimer's disease, ARCD is a nonpathological impairment of cognitive function that usually develops progressively from midlife onward. As the population continues to age, ARCD is becoming a critical issue. Previous research has suggested polyphenols from fruits such as blueberries and grapes may have the ability to support memory and neurological health as we age.

The present study clearly demonstrated that supplementation with Neurophenol® (600 mg/d) for six months improved episodic memory, or the ability to recall previous events and specific details such as people, times and places, in healthy elderly subjects, specifically in those with the highest memory decline at baseline. Researchers found that the polyphenol intervention was able to reverse these memory alterations in healthy elderly individuals with a lower level of memory performance, giving hope to those who are already experiencing some neurocognitive and memory issues.

In an effort to combat cognitive decline, Atrium Innovations joined a consortium of French and Canadian researchers and commercial partners to create the Neurophenols Project, an international research initiative dedicated to developing and marketing innovative natural products to support neurocognitive health. First-to-market products containing Neurophenol® are now available from Atrium Innovations brands Pure Encapsulations®, Douglas Laboratories® and Garden of Life®. 

"As part of our long-standing and successful collaboration with the world-class research team at INAF, we have consistently explored nutritional interventions with real promise for positively impacting health," explained Barry Ritz, Chief Scientific Officer for Atrium Innovations. "This collaboration has allowed us to meaningfully contribute to nutrition science and create innovative new products to address important issues, such as cognitive decline in the aging population."

This study is part of a multiyear research collaboration between INAF and Atrium Innovations exploring the impact of lifestyle and nutritional interventions on health. In addition to Neurophenol®, the collaboration has yielded other important discoveries on the clinical applications of polyphenols, fish oil and systemic enzymes and their role in improving cardiometabolic health outcomes.

STUDY METHODOLOGY:
The study evaluated the results of 215 healthy male and female subjects between 60 and 70 years of age with a body mass index (BMI) between 20 and 30. The study used a bicentric, double-blind, randomized, placebo-controlled model. The study was divided into three visits at investigational sites and two follow-up calls. Subjects were seen for a pre-inclusion visit, followed in two to four weeks by a baseline visit, and an end-of-study visit 24 weeks after the first visit. Follow-up calls were made eight and 16 weeks after the first visit. All participants' Mini Mental State Examination (MMSE) scores were 26 < MMSE score ≤ 29. To minimize the confounding effects of a variety of diet, health and lifestyle factors, all participants had to meet criteria and be capable and willing to comply with protocol in order to be eligible for the study. Subjects were randomized and assigned to receive either the active treatment, a polyphenol-rich extract from grape (Vitis vinifera L.) and wild blueberry (Vaccinium angustifolium Aiton) (PEGB), or the placebo. Subjects consumed two 300mg capsules of Neurophenol^® orally each day for 24 weeks. The study was not designed to look at a rate of change in cognition over time. The results provide evidence that supplementation with specific polyphenols from grape and blueberry improves verbal episodic memory in healthy elderly people. Moreover, it was demonstrated that a nutritional intervention with polyphenols is able to reverse the episodic memory alterations in healthy elderly people with a lower level of memory performance.
