Supports joint function and tissue health*

To understand glucosamine's role, it is important to understand joint structure and function. Cartilage in the joints acts as a shock absorber to cushion the blows of daily wear and tear. Joint cartilage is made of a unique connective tissue that consists of collagen and proteoglycans. Collagen is a strong, fibrous, insoluble protein. Proteoglycans are large, carbohydrate-rich protein chains made up of 95 percent polysaccharides and 5 percent protein called glycosaminoglycans (GAGs). GAGs are composed of repeating two-sugar units (disaccharides) that contain glucosamine sulfate and other amino sugars. Surrounding the joint cartilage is synovial fluid, which contains many substances including its chief component, hyaluronic acid. Hyaluronic acid forms the backbone of other proteoglycans and is responsible for the thickness of synovial fluid as well as its lubricating and shock-absorbing properties. Synovial fluid also provides nutrients for the joint cartilage.

Glucosamine sulfate is a normal constituent of glycosaminoglycans in cartilage and synovial fluid. In essence, glucosamine sulfate provides important building blocks for cartilage production. Laboratory studies suggest that glucosamine may also function to stimulate production of cartilage-building proteins. It is also thought that the sulfate portion of the molecule contributes to the efficacy of glucosamine sulfate in the synovial fluid by providing the elemental sulfur needed for strengthening cartilage and aiding glycosaminoglycan synthesis. ^1,2,3

Glucosamine sulfate has been the subject of research for over twenty years. Clinical trials as well as experimental studies have repeatedly supported the efficacy of oral glucosamine sulfate in supporting joint function. In one large open trial, over 1200 people took oral glucosamine sulfate for periods ranging from 36 to 64 days. In this multi-center trial, ninety-five percent of the subjects experienced greater joint comfort and increased mobility. The physicians reported "good" results in 59%, and "sufficient" results in 36%. Furthermore, the improvements in joint health lasted for up to three months after the glucosamine sulfate was discontinued. ³

Promotes optimal joint comfort, function and flexibility*

Boswellia serrata (Indian frankincense) has been used for centuries in the Indian Ayurvedic system of medicine to maintain healthy joints. Even today, this is one of the primary uses for this plant in Ayurvedic medicine. Boswellic acids have been shown to support healthy joint tissue, maintain circulation to joints, enhance joint mobility, and promote joint comfort in animal models without known side effects. ⁴

Boswellin® is an extract rich in boswellic acids. Boswellic acids are potent modulators of enzymes involved in leukotriene synthesis in vitro, promoting a healthy balanced production of these components of the immune system.⁵ Healthy leukotriene balance can lead to enhanced joint function. A human clinical study was conducted to assess the effects of supplementation with a formula containing Boswellia, Curcumin and other nutrients on joint function. In this double-blind placebo-controlled crossover trial, participants were randomly assigned to receive the herbal formulation or a placebo for 3 months. Following this 3-month period, the treatments were reversed for an additional 3 months. The results showed that while each group was receiving the herbal formulation, they had superior joint function and a greater sense of joint comfort when compared to the placebo groups.⁶ Other trials lend further support to Boswellia’s ability to promote healthy joint function.^4,6,7

Curcumin is a potent antioxidant that has known free radical scavenging activity. This activity of Curcumin is thought to play a major part in its role as a joint protective nutrient. In fact, the numerous beneficial effects attributed of whole turmeric are thought to stem in large measure from the antioxidant properties of curcuminoids. Antioxidants neutralize free radicals, which are highly unstable molecules that can damage cellular structures through abnormal oxidative reactions. Curcumin is not toxic to cells, even at high concentrations. Pure Curcumin was shown to be less protective than a mixture of curcuminoids, indicating a possible synergism among the curcuminoids.⁸

Curcumin demonstrates several other in vitro effects linked to free radical scavenging. Curcumin scavenges nitric oxide, a compound associated with the body’s inflammatory response.⁹ Curcumin also demonstrates in vitro inhibition of certain enzymes involved in promoting inflammatory reactions in the body. Together these results strongly suggest that Curcumin is a potent bioprotectant with a potentially wide range of therapeutic applications.^9,10,11

Preliminary human trials have assessed the therapeutic potential of Curcumin, with results that verify the traditional use of turmeric as an herb to enhance joint health. In a short-term double-blind, cross-over, comparative study, eighteen people were randomized to receive Curcumin (1200 mg daily) or an alternative therapy for two-week periods. The participants in the Curcumin groups were shown to produce measurable enhancements in joint flexibility and walking time.¹² Research suggests that Curcumin and Boswellia work extremely well in combination to benefit joint health and mobility, as trials combining both nutrients have yielded highly positive results.

Bioperine-Nature’s Absorption Enhancer Boosts Nutrient Absorption*

Traditional Ayurvedic herbal formulas often include black pepper or long pepper as synergistic herbs. The active ingredient in both black pepper and long pepper is the alkaloid, piperine. Experiments carried out to evaluate the scientific basis for the use of peppers have shown that piperine significantly enhances bioavailability when consumed with other substances.¹³   Several double-blind clinical studies have confirmed that Bioperine® increases absorption of nutrients.¹⁴

Curcumin is known to be poorly absorbed in the intestinal tract when used on its own, thereby limiting its therapeutic effectiveness. Oral doses are largely excreted in feces, and only trace amounts appear in the bloodstream. However, a study has shown that concomitant administration of 20 mg of piperine with 2 grams of Curcumin was able to enhance Curcumin bioavailability by an astounding 2000%. ¹⁵ These results speak to the wisdom of including a small amount of Bioperine® in the formulation to ensure nutrient bioavailability.
