PREDATOR POWERCold, stone and snow, I grow through it, that's why I give strength to everyone |
During the Cold War, the Soviet Union conducted extensive research into the bioactivity of numerous plants and their effects. This research remained a state secret for decades. With the rise of democracy and the erosion of the USSR's political boundaries, much of the old Russian research was slowly revealed to the Western world. One of these secret studies gave Soviet athletes a significant advantage and has only been shared with us in the last twenty years. Rhaponticum carthamoides, also known as Leuzea, contains a remarkable substance called 20-Hydroxyecdysone, which increases (muscle) strength* and stimulates muscle building/muscle growth/lean muscle mass during sports*.

History
Leuzea, or Maral root, is a very rare, endemic plant with a height of 130 cm. Leuzea contains a unique group of bioactive compounds and grows on the mountain slopes of Southern Siberia (Altai and Sayan). Leuzea does not grow in other parts of the world and only grows in Southern Siberia. Due to the limited distribution of Leuzea in the wild and because it grows slowly, the harvesting and gathering of wild-growing Leuzea root in Russia is controlled by the government and subject to severe restrictions. The history of Leuzea as a natural plant is particularly evident in Siberian, Mongolian, and Chinese medicinal traditions. It began centuries ago when local hunters observed the behavior of a variety of deer known as Maral. During mating, Maral deer fight with each other and are often seriously injured. To regain strength and recovery, deer would dig up and eat Leuzea roots. The plant was subsequently called maral root; now, its official common name is Leuzea root. Local shamans discovered that humans also benefited from the consumption of dried Leuzea root during periods of recovery*. Traditionally, Siberians consumed Leuzea tea mixed with Rhodiola Rosea root as a natural booster for fatigue (Rhodiola Rosea) and to maintain physical balance (Leuzea) to survive the long Siberian winter. Traditionally, shamans used Leuzea to brew tea and thus activate mental resilience*. Modern studies of Leuzea began in the 1940s in the Soviet Union, led by researchers including E. Kushka and Y. Aleshkina. During this period, the country was looking for solutions to help restore the strength of soldiers. In 1961, after more than 20 years of research and clinical studies, Rhaponticum Carthamoides was officially included in the Soviet pharmacopoeia as an aid (9th Edition of the State Pharmacapoeia of the Union of Soviet Sociatlist Republics) for recovery periods*, for fatigue*, for more strength* and has a positive effect on the immune system*. Recent studies have shown that Leuzea activates your natural energy in the body*. In addition, it has a positive effect on the immune system*, blood vessels*, is good for the circulation, contributes to normal digestion* and is good for intestinal function*. Leuzea is also used to support the menopause process*.
Application
1 to 2 grams daily, depending on your body weight. Add 1/2 teaspoon of Leuzea root to your smoothie, juice, protein shake, yogurt, tea, or latte. This supplement is not a substitute for a varied diet. Do not exceed the recommended daily dose. Consult your doctor if pregnant or breastfeeding. Keep out of reach of young children. For best (sports) results, mix with Rhodiola Rosea.
Bioactivity
The main active ingredients responsible for the specific constructive effect are a mixture of compounds called "Levseins." Levseins represents a complex of more than 10 ecdysterones, including 20-beta-ecdysterone, makisterone C, 24-dehydromakisterone A, carthamosterone, polypodyne B, and ajugasterone. Ecdysterone, also called beta-ecdysterone, is a polyhydrodated sterol belonging to the Ecdysone group.

Science
Under European and Dutch law, we are not permitted to make medical claims about foods and dietary supplements, regardless of whether there is scientific evidence. This means we cannot mention specific health benefits of Leuzea root unless they have been approved by the EFSA (European Food Safety Authority). For herbs and botanicals, most claims are currently "on hold," meaning they have not yet been fully approved.
Although we are not permitted to make medical claims, several scientific studies are available on Leuzea. To help our customers better understand the potential benefits, we offer an overview of these studies. We recommend reading these studies yourself to learn more about Leuzea's properties.

Leuzea: Powerful Support from Nature
Wild picked
Our Leuzea root is wild-harvested in the Siberian Altai Mountains, where the harsh weather conditions contribute to its natural strength and resilience. Thanks to these extreme growing conditions, the root contains high levels of bioactive compounds, including ecdysterone.
Top performance
Wang Junxia, world-renowned marathon runner and world record holder, trained under coach Ma Junren in the Tibetan highlands. She took Leuzea, Rhodiola, and Ginseng as part of her supplements for larger and stronger muscles* and a beneficial effect on endurance* (Rhodiola Rosea), which supported her exceptional performance.
Transition process
Menopause is a natural process in which menstruation stops and hormones change, but it remains a taboo topic, rarely discussed, despite the physical and emotional changes many women experience. Leuzea supports the natural transition* and provides strength during menopause. A trusted source of power to empower yourself through every stage of this important journey.
