MegaNatural®-BP Structure/Function Claims Language

MegaNatural®-BP is a unique form of grape seed extract that has been clinically shown to help maintain healthy blood pressure levels within the normal range.

MegaNatural®-BP, a unique form of grape seed extract, is an antioxidant that helps support endothelial function by maintaining healthy nitric oxide levels that are within the normal range. This helps support healthy vasodilation and blood flow.


If a formulator begins with a branded ingredient that has endured vigorous R&D already, it could ultimately save time, and give confidence because a company’s R&D is backed by additional studies.Anil Shrikhande, President, Polyphenolics, in an interview printed in the June 2014 issue of Natural Products Insider.

Formulators and marketers continue to realize the strong benefits of using premium grape seed extracts and grape skin extracts in supplements, functional foods and beverages. Grape extracts naturally contain polyphenols. Polyphenols function in normal metabolism, doing more than just scavenging oxygen radicals.

Not all grape seed extracts are created equal.

Polyphenolics has worked diligently at researching methods and developing the science behind our MegaNatural® grape seed extracts. Polyphenolics’ extracts are produced using a patented, water-based extraction process, concentrating natural compounds that have been scientifically connected with exceptional health benefits. They support maintenance of the natural supple elasticity of healthy blood vessels, thereby contributing to a healthy cardiovascular system.

In the July/August 2014 issue of Nutrition Industry Executive Magazine, Dr. Anil Shrikhande stated, ‘“These special GSE’s are also being incorporated in sports nutrition supplements because of their value in increasing nitric oxide formation, blood flow modulator and decreasing the antioxidative capacity of the blood. The values of these GSE’s are unique in managing the healthy blood pressure and healthy blood glucose levels.”

Shrikhande also ‘pointed out that another trend in the supplement area is to provide different capsules in daily vitamin packs, which usually include an antioxidant. “Water containing nutrients and antioxidants is also a rapidly expanding business to differentiate from the traditional soda market,” he added. “Providing an antioxidant in water also meets the criteria of hydration of the body…”

Polyphenolics creates effective, condition-specific products that have been clinically shown to work. MegaNatural® grape seed extracts are now included in formulations targeting heart health, sports nutrition, blood pressure maintenance, and various prevention lines for men and women from some of the most successful supplement companies in the world.
