Shellfish Free / Vegetarian Safe / No Sodium

man running a marathonInvigoFlex® GS contains a proprietary blend that now includes a shellfish free and vegetarian safe Glucosamine Sulfate. This means if you are vegetarian, allergic to shellfish, or simply want to avoid animal/fish source glucosamine, then InvigoFlex® GS is right for you. In addition to being vegetarian safe, it provides a premium-quality and USP-grade formulation, and its overall patented Isotopic Signature Carbon Tracing method (ISCTM) ensures quality assurance and ingredient purity – which is essential in having a vegetarian and shellfish free ingredient. We have also recognized that customers are now also looking to control their sodium intake within their diets, including with their dietary supplements. While other glucosamine products may have upwards of 50mg to 150mg of sodium per serving, InvigoFlex® GS contains little to no sodium in its formulation, which helps customers ensure InvigoFlex® GS does not interfere with their healthy diet

The added benefit of Boswellia Serrata

A relatively new ingredient to the joint market is Boswellia Serrata. Also known as Indian Franincense, Boswellia Serrata, a plant and natural extract, has been shown to have many different health applications, including supporting joint health. It's natural properties have also been known to have anti-inflammatory properties as well as antioxidant benefits and may even help with reducing pain from overexertion and exercise. The benefits of Boswellia Serrata have been validated and confirmed in multiple clinical studies. The gum resin of Boswellia Serrata is valued as a source of healthful "phytonutrients". Such extracts are used as ingredients in dietary supplements and cosmetics, to support healthy aging. However, the most popular use of Boswellia Serrata is in joint health as it supports normal joint functions and mobility.

The anti-inflammatory properties of Boswellia Serrata can be seen in the gum resin and is attributed to the presence of "boswellic acids". Boswellic acids were found to inhibit two pro-inflammatory enzymes, 5-lipoxygenase (which generates inflammatory leukotrienes) and Human Leukocyte Elastase (HLE). HLE is a serine protease which initiates injury to the tissues, which in turn triggers the inflammatory process. This dual inhibitory action on the inflammatory process is unique to boswellic acids.

The Glucosamine Sulfate Difference

While many products today use different versions of Glucosamine, such as Glucosamine Hydrochloride, InvigoFlex® GS specifically uses Glucosamine Sulfate as it has been proven in many different studies. Glucosamine Sulfate is one of the most popular and proven ingredients used to help with joint discomfort. As a natural ingredient, Glucosamine Sulfate is essential in maintaining cartilage in the joints while defending, strengthening, and promoting overall joint flexibility. Glucosamine Sulfate has also been investigated for its ability to modify underlying cartilaginous degeneration in joints, and therefore to potentially provide relief to patients. The majority of studies have demonstrated the ability of Glucosamine Sulfate to alleviate symptoms of joint discomfort due to overexertion and exercise as well as support joint function and cartilage. Glucosamine Sulfate has been used in many pre-clinical and clinical studies. Leading medical journals have cautioned that without head-to-head trials, other glucosamine products, like Glucosamine hydrochloride (HCI), may not provide the same benefits as Glucosamine Sulfate.

The benefit in taking InvigoFlex GS comes in two forms. First, it provides much needed short-term relief (1-3 months) by helping to reduce pain from overexertion and exercise. Second, it provides long-term benefits in maintaining the joint cartilage and promoting overall joint health on a consistent basis. Additionally, less negative side effects have been reported compared to other joint products.
