Unlock a healthier, happier future with Visterra's premium, thick burdock root extract. For over 20 years, we've been dedicated to producing the highest-quality burdock root extract, both in its concentrated liquid form and capsule format. Our extensive research into burdock's biochemical composition and beneficial properties has led to the development of proprietary technology for processing fresh burdock, maximizing the preservation of bioactive compounds. We've published numerous scientific papers on the health benefits of burdock root extract and continue our ongoing research. In 2003, Visterra scientists made a groundbreaking discovery: the presence of L-β-asparagine crystals in spring-harvested burdock root extract—a compound absent in autumn harvests. Further research revealed significantly higher anti-tumor activity in spring burdock. Since then, Visterra has exclusively used fresh, May-harvested burdock root. We are the only company in Russia that independently cultivates and processes fresh spring burdock root into extract. Unlike other producers, our burdock is never dried or subjected to prolonged storage, preserving its rich bioactive composition, including inulin, protein, essential fatty acids (arginine, Omega-3, Omega-6, etc.), tannins, vitamins, minerals, and a wealth of macro and micro-elements (potassium, calcium, magnesium, iron, and many more) that contribute to overall well-being.
