OPCs            byPass this intro> http://opcs.us/anti-O.htm  

Fundamental and prevalent in nature, including the oldest known surviving tree species (Acacia);

derived and isolated around 1950 from the red skin of peanut, and then grape seed and tree bark;

and now institutionally produced in Europe as a vitamin in the manner patented in France and U.S.


The case was made for its status as vitamin (P),

appearing in Stedman's 1972 Medical Dictionary --

[aka "citrin"] -- but absent in current editions of Stedman's!!


It's status as vitamin was wrongly denied by the FDA,

for lack of demonstration of the affliction reliably arising when lacking in the diet.

The "affliction" is subOptimum health,

which occurs over a longer period

finally manifest in:  slow healing of injury to collagen:

1/3 of your body weight is collagen.

(collagen holds your 10-billion cells in place; keeping arteries, veins brain et al:  healthy).


Jacques (Jack) Masquelier (1921-2009) completed his PhD in Bordeaux in 1950;

impassioned for his remaining life to institutionalize assured OPC production

while learning and reporting the results of clinical trials demonstrating:

no risk of overdose; and multiple positive health benefits

(recently affirmed by National Institute of Health), 

especially as co-factor of vitamin C,

facilitating:  building/maintenance/reBuilding/repairing:  collagen the subject of sports injuries.

1/3 of your body weight is collagen -

the binding of muscle cells and bone and every structural component of your body. 

Bones, teeth, nails and cornea are modified collagen.  Brain is wrapped in collagen.

Collagen is the basis of skin, blood vessels, GI tract and organ encasement.

Diverse nutritive benefits result in optimizing mammalian biology, health, and function:

Anti-oxidant; Anti-inflammatory; Anti-Cancer; Anti-Caries; Anti- neural degeneration.

Beyond his published scientific papers, a colleague authored with him the 1993 textbook:

OPC in Practice, which john has read several times and reported on wiki.

Curiously, except for 2013 obscure reference in a Harvard publication;

but well known by USDA;

this gift of nature is largely ignored by the mainstream medico/pharma. 

However, belatedly, OPC is increasingly the focus of new research

confirming its effective and reliable impact on health;

most prominently:  The National Institue of Health.


More prevalent are increasing reports of common food sources,

beyond that established by Masquelier: 

1. GSE  Grape Seed Extract - a source that is abundant, low-co$t waste product of white wine

    Note:  red wine is red because the whole grape is fermented.

2. Some species of Pine bark

3. Cacao, pecans, apples (GrannySmith et al), hops, fava beans ...


U.S. Department of Agriculture has cataloged OPC content in food for over a decade.


By far:  most concentrated natural source of OPCs is (chocolate) cacao beans (impassioned web).

The original story (pdf -produced by The Lloyd Library)

long preceded the modern (1950) _continuing discovery in nature of flavanols -


The pearl of flavanols is OPCs

Not a salesman; an educated, impassioned teacher:

This report is developing, beginning 2010, continuing the active focus in 2021

by this writer and canines who enjoy improving health with this important vitamin.
