MetaLeptin is a cutting-edge option for those in need of joint support related to excess body fat. Exciting, new research shows that fat cells send messages (via leptin and other signaling molecules) to joint tissue cells. These messages can trigger a cascade of events that damage the health and integrity of joints. MetaLeptin works by changing the “communication” between these cells, resulting in a more naturally healthy joint environment that can help you stay comfortable and be active.*

A paradigm shift is occurring in our understanding of how excess body fat affects joint health. This new paradigm suggests that joint health has a systemic underpinning that carries a metabolic component. At the heart of this systemic mechanism, adipose tissue has emerged as a dynamic organ that releases several signaling molecules or mediators (e.g., adipokines). These adipose-generated mediators “communicate” with cells of joint tissues, sending messages that result in changes to cartilage and synovial fluid that ultimately affect joint health, function, and comfort. In a search to discover substances that can help change this cellular “communication” to a more healthy exchange, scientists tested a proprietary combination of hyaluronic acid and other glycosaminoglycans called ORALVISC®, which is the main ingredient in MetaLeptin.*

In a double-blind, randomized, controlled study, an evaluation of the effects of ORALVISC (80 mg/day) on multiple mediators associated with joint tissue changes in overweight individuals was undertaken. The results were very promising.

Leptin is an adipokine (or adipocytokine), a cell-to-cell signaling protein that originates from adipose. It is one of the central mediators being investigated as a metabolic component that affects joint health. Leptin is not only thought to have synergistic actions with other damaging cytokines, including IL-1, TNF-alpha, and IFN-gamma, but it is also thought to affect joint tissues through activation of iNOS, stimulation of cartilage remodeling enzymes, induction of synovial membrane cytokines, and bone matrix regulation. Increased levels of leptin have been observed in the chondrocytes, synovial fluid, and osteophytes of human subjects; and increased levels of leptin are thought to play a role in cartilage homeostasis. It is postulated that supporting a reduction in levels of synovial and serum leptin will prove to be beneficial in cartilage homeostasis and turnover.*

Three months of supplementation with ORALVISC resulted in a significant (P < 0.05) decrease between initial and final—and between supplement and placebo—synovial and serum leptin levels, as measured by immunoassay. In addition, the supplemented group lost an average of 1.21 lb compared to an average 1.65 lb weight gain in the placebo group. The researchers concluded that reducing leptin levels could be beneficial to cartilage homeostasis and turnover, and that the weight loss could be due to the decrease in leptin levels associated with healthy joint function and changes in overall metabolism.*

Cytokines and Chemokines are cellular communication mediators; some of these activate chondrocytes and synovia to break down joint extracellular matrix and trigger a cascade of damaging events.[6,7] As demonstrated in the clinical trial, ORALVISC supplementation resulted in a significant reduction in 12 serum and synovial cytokines and chemokines, including IL-1alpha, IL-1beta, and TNF-alpha, after the three-month period. In contrast, the placebo group did not display a reduction in these mediators; and, in some cases, the levels increased, suggesting progression of unhealthy catabolic signaling.*[7]

Glycosaminoglycans (GAGs), such as hyaluronic acid (HA), have numerous functions within joints. For instance, HA has visco-elastic properties that reduce friction between cartilage surfaces, and it has metabolic properties that are critical for homeostasis of the synovial fluid.[8,9] Damaging pathways triggered by signaling molecules result in changes to the synovial fluid environment and have been shown to result in an increase in HA turnover. When the researchers looked at the effect of ORALVISC on HA turnover in synovial fluid, they found that after 12 weeks of supplementation the mean rate of HA turnover declined by 45% (P = 0.046). In addition to the normalization in HA turnover, the researchers also noted that the dietary supplement supported joint comfort and function.*[9]

Bradykinin, a peptide produced in the synovial membrane, is responsible for stimulating nociceptors and initiating the cytokine response to cellular insult. Researchers found that ORALVISC supplementation resulted in significantly lower (P < 0.05) serum bradykinin levels (14.44 ng/mL versus placebo 15.06 ng/mL). Likewise, synovial fluid bradykinin decreased significantly (P < 0.05) in the supplemented group (-0.6 ng/mL versus placebo +0.29 ng/mL).*[10]

The positive results observed for each metabolic parameter studied may have translated into the clinically significant improvements recorded in joint comfort and function as assessed by VAS (visual analog scale) and WOMAC (Western Ontario and McMaster Universities osteoarthritis index) scores.*[11]
