The supplement OmegaXL, from Great HealthWorks, contains 300 mg of Green-Lipped Mussel (Perna canaliculus) Oil Extract (PCSO-524®) containing Omega Fatty Acids, Extra Virgin Olive Oil, Pure Olive Oil, d-alpha Tocopherol (Vitamin E). How effective is OmegaXL compared to Joint Genesis, FleXion, and the Fusion Nano Circle, for improving joint symptoms and joint restoration?

While this has beneficial supporting effects on the joints and muscles as advertised, it will not outshine any of the other strategies you list, which we have described as being of benefit for such issues, particularly, the long-term restoration. The OmegaXL has useful fatty acids and those are a known benefit and often needed because of there being an ongoing deficit in the body. And in those situations where there is a degradation in joint function and muscle function, this is a breath of fresh air from a nutritional standpoint. But it is only a starting point, when there are many individual components needed for long-term healthy well-being of muscles and joints. So this can be a useful adjunct although it would not be our recommended first choice, but down on the list following the others you mentioned.
