Unfortunately, the marketplace is full of imitations, various “extracts” and derivative forms of Dr. Jack Masquelier’s scientifically proven complex. (1-3)

Flavay® is the product—used in the actual experiments—by which Dr. Jack Masquelier patented the "Radical Scavenger Effect." of Flavay®

Consumers need to know that the marketplace is full of imitations, offshoots and derivatives of scientifically proven natural products. Those who are looking for a product that will produce the proven results and not just the "claimed" or "implied" results, want the authentic product that was used in the actual scientific research. This is especially important when you buy a product labeled as "grape seed extract" or "pine bark extract."

"OPC" and "Proanthocyanidins" are Unreliable Names in the Marketplace

When reading product labels, magazine articles and many popular books, the terms "OPC" and "proanthocyanidins" should be considered as generic words and not scientific whatsoever. In most cases, the terms are used as equivalent to "grape seed extract" or "pine bark extract" for commercial interests—or by mistake—and their differences have truly lost all scientific meaning. For example, independent testing found no active OPCs (oligomeric proanthocyanidins) in a leading American brand of grape seed extract—even though it's aggressively marketed and branded as an OPC product.

The following terms are used interchangeably for commercial interests—or by mistake—and their differences have truly lost all scientific meaning in the marketplace:

  • bioflavonoids and flavonoids

  • Oligomeric Proanthocyanidins (OPCs) or Proanthocyanidolic Oligomers (PCOs)

  • polyphenols

Proanthocyanidin clusters must have a certain molecular size to be effective.

Unfortunately, many companies have used Dr. Jack Masquelier’s name and research in unauthorized ways to promote illegitimate extracts. There are many, many suppliers of grape seed and pine bark extracts who use various and unproven manufacturing processes, which leads to widespread differences in products labeled at "grape seed extract" or "pine bark extract" in the marketplace. Together with widespread confusion and misunderstanding as to the differences between vague "extracts" and their active principles, it's practically impossible for retailers and consumers to distinguish inferior products from quality ones.

Flavay® customers say it best:

“Flavay® is terrific. I've had concentration problems, well, for 60 years, all my life. I couldn't have direct eye contact with people when talking with them because I couldn't concentrate. I told jokes but couldn't make people laugh because I couldn't keep my concentration. Now I can look people in the eye. Now I can make people laugh! I don't know how it works but it works and it is terrific.”
Mr. Wayne S.

“I just wanted to write and say WOW... I was so skeptical of your product at first and really had a negative attitude when I started taking it. I am a 40yr old female with anxiety, mild ADHD and a host of Arthrtis and inflammation issues. It was a struggle for me to get out of bed everyday and focus on what needed to be done. I had no focus, no attention span, no energy, and no desire to do anything. About a week into taking Flavay, I started noticing that I could think a little clearer. My rheumatoid arthritis flare-ups weren't so bad, though I still have them. Also, I haven't been procrastinating as much and also, my boss has noticed I've been a little more social. I attribute all of this to feeling better, and having more energy. I never thought I would feel like my old self again. I don't know exactly how you do it,...but this stuff works! I am telling all of my friends to try it because you've given me my old life back! Thank you!”
Ms. L. A.

“I want to thank your company for Flavay Plus®. My aunt and grandmother had Alzheimer's. In my early 50's I was beginning to experience some memory problems, but not anymore, and I'm grateful.”
