Knotweed Powder

Organic Japanese knotweed root (Polygonum cuspidatum), milled into a fine powder. One ingredient, nothing added. 8 oz, 226 servings.

Where does resveratrol come from naturally?

Grape skins and red wine are the famous sources, but Japanese knotweed root carries much more of it, which is why it is the main commercial source of resveratrol. Resveratrol is one of the most studied plant polyphenols. Our powder is the whole organic root, milled, for people who want the plant rather than a purified extract.

Why you'll love it
  • The whole root, milled, not a purified extract
  • USDA Organic and Non GMO, vegan and gluten free
  • One gram is a serving, about a third of a teaspoon, so the jar lasts
  • Third party tested for heavy metals on every batch; we tested twelve suppliers before choosing this one
  • Strong and bitter, which is how the root tastes; it hides best in a bold smoothie
How people use it

A serving is 1 g, about a third of a teaspoon. The taste is strong, earthy and bitter, so blend it into a fruit smoothie, stir it into a tincture, or fill your own capsules. Keep the jar sealed and dry.

Fun fact: Japanese knotweed is one of the most vigorous plants on earth. In Britain it is listed as an invasive species, and it can push up through asphalt.

Try it in one of our knotweed powder recipes.

All orders come with a 30 day, no questions asked return policy. Free shipping on orders over $50.

Questions people ask
What is Japanese knotweed powder good for?

Japanese knotweed root is the main natural source of resveratrol, the polyphenol also found in red wine. Our powder is the whole organic root, milled, with nothing added.

How much knotweed powder should I use, and how?

1 g a day, about a third of a teaspoon, blended into a smoothie or a tincture or filled into capsules. The 8 oz jar holds 226 servings.

Where does your knotweed powder come from?

Organic Japanese knotweed root, milled and packed in Southern California in a GMP certified facility. We tested twelve suppliers for heavy metals before choosing this one.

How is it tested?

Every batch is third party lab tested for heavy metals and potency, and the reports are on our third party testing page. We only put a badge on the page if the label backs it.

Does it contain anything else?

No. The only ingredient is organic Japanese knotweed root. Vegan and gluten free.

How should I store it, and how long does it keep?

Sealed, cool and dry, away from sunlight. Use the best before date on the jar. Once opened keep the lid tight, because the powder clumps if it takes in moisture.

Pairs well with Strawberry Powder, Raspberry Juice Powder and Celery Powder.

Every batch is tested for heavy metals. This root is well below the FDA limit for lead and just above California's stricter Proposition 65 limit, so California law requires this notice. CA WARNING: Can expose you to Lead and lead compounds, a carcinogen and reproductive toxicant. See www.P65Warnings.ca.gov/food.
