Vincaria® – Is a Patented, Highly Concentrated Substance:

(Support studies listed in the Scientific Studies)

     Clinically effective: Has been found in a preliminary study to reduce pain associated with activity in individuals with osteoarthritis of the knee.

Vincaria® is a patented alkaloid-deplete extract from the Uncaria species vine shown in human clinical studies to reduce inflammation and pain associated with osteoarthritis. It’s mechanism of action is regulation of the TNF-alpha, a cytokine responsible in over 35 inflammatory pathways, via the NFkB. It also protects the gastrointestinal tract from NSAID (e.g. aspirin) induced injury, such as ulcers.

Inflammation is a key element and chronically active in many diseased states, including inflammatory bowel disease, arthritis, sepsis, gastritis, asthma, and atherosclerosis. Nuclear Factor Kappa B (NFkB) is a protein complex found in most cells that acts as the “on-off” switch for many genes involved in various types of inflammation.

Beginning in 1998, scientists at LSU Medical School and later Albany Medical College began studying the two cat’s claw species. It was discovered that UG acts as a powerful anti-inflammatory agent by regulating TNF alpha, the master “On-Off” switch in our bodies responsible for over thirty-five different types of inflammation – from arthritis to asthma. When alkaloid traces were extracted and removed from UG, a patented process which created Vincaria®, it was even more therapeutic.

Subsequently, a clinical trial was conducted in which a single once-a-day 100 milligram dose of Vincaria® was effective in ninety percent of patients, the majority in less than five days. It was then used as an anti-inflammatory component, both to promote healthy skeletal, muscular and gastric health in obesity. In a separate trial, it was combined with a natural mineral supplement again successful for arthritis and later, with RNI 249, a maca extract, for osteoarthritis of the knee.
