Knotweed Powder

Unlock the Power of Resveratrol

Our USDA Organic Japanese Knotweed (Polygonum cuspidatum) Powder is designed for those who seek a potent, authentic source of natural resveratrol, an antioxidant traditionally valued for supporting heart health and optimal circulatory function.

What’s Inside

We provide 100% pure, organic Japanese Knotweed root, finely ground to preserve its natural bioactive profile. Our powder is crafted without additives, fillers, or preservatives of any kind. Because this is a raw, undiluted botanical, it possesses a distinctively bold, bitter flavor. This is nature in its most concentrated form, delivered exactly as the earth intended.

Why You Need It

Given the intensity of its natural flavor, it is the perfect candidate for masking in a nutrient-dense smoothie, incorporating into a custom tincture, or filling into DIY capsules. By choosing our organic powder, you gain total control over your intake and avoid the hidden binders found in commercial supplements. Whether you are exploring ancient herbal wisdom or simply seeking a clean, powerful antioxidant boost, you are choosing a traditional powerhouse that connects your daily routine to the resilience of nature.

Note, we tested 12 different polygonum suppliers and found the one with the lowest levels of lead. Our Japanese knotweed is well below the FDA threshold but we are still just a bit over above CA 65 requirements, which are the strictest in the world when it comes to heavy metals. So we have to include the warning below:

CA WARNING: Can expose you to Lead and lead compounds, a carcinogen and reproductive toxicant. See www.P65Warnings.ca.gov/food

Remember, all orders come with a Full 30 Day, no questions asked guarantee! FREE shipping for all orders over $50.

We offer a full 30 day, no-questions-asked return policy. No fine print, no restocking fee. A happy customer is hopefully a returning customer. That’s our philosophy.

Simply contact customer service at info@naturerestore.com with your order # and “returns” in the subject line. Since we’re a small operation, we’re able to reach each email manually every day, Monday-Friday. 

We process orders Monday through Thursday same day, with 12pm noon PST as our cutoff time. Shipping is through USPS or UPS ground advantage. We ship from Orange County California, so most west coast orders are delivered usually within 4 business days. East coast orders might take up to 7 working days. Note, we close our warehouse on Fridays.

We sure do! We have quite a number of customers based in Canada as well as Europe. Note, it does take longer, sometimes up to two weeks and the cost will vary on weight. The best shipping rate will be on orders with 5 or more items, so stock up!

Each order comes with an email receipt with your order confirmation and when we ship your item, there’s a followup email with your shipping tracking number

The easiest is info@naturerestore.com, we check that inbox all throughout the work week and sometimes even on the weekends. We know, bad habit.

We have to be honest, this product is easily one of the three least favorite in terms of taste. It’s a powerful wallop of antioxidants that is pretty bitter on the taste buds. We recommend putting it into DIY capsules or putting a small amount, ¼ of a teaspoon into a larger smoothie.

Yes! The plant has some of the highest naturally occuing amounts of resveratrol. Resveratrol is the same antioxidant found in red wine.

With Our Products You May...

Our Japanese Knotweed powder contains high levels of trans-resveratrol (yes, that thing in red wine) which works to support healthy heart functions.

Experience It Yourself!
