Resveratrol and the Power of Industrial Science
Currently featured in nearly 20,000 scientific publications, this polyphenolic compound is best known for its association with longevity. Although it was first discovered in 1939 by Japanese chemist Takaoka, its popularity skyrocketed in the 1980s thanks to a phenomenon known as the “French Paradox.”
Researchers observed that the French had a high intake of red meat but surprisingly low rates of cardiovascular disease. Delving deeper, they attributed this paradox to red wine—specifically, to the resveratrol it contains. Thus began the widespread association of resveratrol with heart health and extended lifespan.
But there was a catch:
Natural sources like grapes, grape skins, seeds, mulberries, and peanuts contain extremely low levels of resveratrol—sometimes in the nanogram range. To deliver a standard daily dose of 200 mg through supplements, capsules, or beverages, researchers needed a scalable source.
This is where Polygonum cuspidatum comes in.
The dried roots of this plant contain 3–5% resveratrol by weight—an astonishingly high concentration. That’s approximately 1,000 times more than the amount found in red grape skins. Research quickly confirmed that this plant was industrially viable, and by the early 2000s, both the U.S. and EU had recognized Polygonum cuspidatum (a common and fast-growing plant, also known as Japanese knotweed) as the gold standard source of resveratrol.
In fact, if you check the label of any global resveratrol product today, you’ll see this plant listed as the source—never grapes.

While grapes, mulberries, and peanuts do contain resveratrol, they are simply not viable for industrial production. Red grape skin, for instance, contains only about 30–50 mg/kg, while Polygonum cuspidatum root contains 30,000–50,000 mg/kg.
This is exactly why I love industrial science.
While most people focus on familiar sources, science dares to look elsewhere—to challenge assumptions and seek more efficient, scalable, and surprising solutions.
