Age, mechanical use and diet are some of the factors that can affect our connective tissues, which in turn affect the quality and mobility of joints. Glucosamine is produced naturally within our bodies to support the structure and function of joints and cartilage. If our bodies do not produce sufficient glucosamine this can limit the ability to repair wear and damage in our joints. A balanced diet is crucial to supplying the nutrients required to produce glucosamine and other connective tissue components but sometimes we need some support over and above what the diet can provide. Our joint supporting supplements supply glucosamine, as well as a combination of other joint-supporting nutrients such as manganese. Omega 3 supplements such as fish oils or krill oil are also associated with joint support, as Omega 3 fatty acids are believed to have anti-inflammatory actions.
