Pharmaceutical-Grade Manufacturing
Exceptional quality and consistency. Every batch of raw materials undergoes identity verification, microbial testing, and heavy metal analysis at our U.S. facility.
Learn about our process
Ideal for addressing ongoing health challenges, our pharmaceutical-grade extract offers researched support for microbial balance, healthy immune function, and cardiometabolic health.*
Extensively Researched
Our Japanese Knotweed extract begins with carefully sourced Polygonum cuspidatum root, harvested at peak maturity to maximize active compound content. Every batch undergoes identity verification and contaminant screening before entering production.
Refined through decades of experience, our hydro-ethanol extraction process preserves the root’s full profile of polyphenols and anthraquinones — including resveratrol, emodin, polydatin, and flavonoids — to ensure broad-spectrum activity and high bioavailability.
Ingredients
Active Ingredient:
Japanese Knotweed (Polygonum cuspidatum) root extract – 1.5 mL
Other Ingredients:
Mineral water, ethanol (20–24%)
What is Japanese Knotweed, and how does it support health?
Japanese Knotweed is a clinically studied botanical used in traditional medicine for more than 1,500 years. Its root contains resveratrol, emodin, polydatin, and flavonoids — bioactive compounds that provide broad-spectrum support for microbial balance as well as inflammatory and immune function, cardiovascular health, and healthy blood glucose metabolism.*
Why was this formula developed?
Leading integrative practitioners asked us for a high-quality Japanese Knotweed extract for use in multi-layered microbial and immune support protocols. This formula complements other NutraMedix microbial support formulas.
How is it different from other Japanese Knotweed extracts?
Our proprietary hydro-ethanol extraction process captures the root’s complete profile of bioactive compounds — unlike other extraction methods, which only capture isolated compounds. In addition to delivering broader clinical benefits, this process preserves the natural synergies between each compound, enhancing absorption and bioavailability.*
Is it safe for everyone?
Japanese Knotweed is generally well-tolerated at recommended doses. Not recommended for pregnant or breastfeeding women, children under 3, and patients taking anticoagulants, antiplatelet medications, estrogen therapy, or medications metabolized by CYP450 enzymes.
Research-backed
“I love NutraMedix products. Most importantly, they work. Excellent quality, backed by tremendous research and I’ve just had good success as a clinician.”
