Omega XL is a fish oil supplement designed to reduce joint pain and improve overall health, and omega-3 is the main ingredient found in Omega XL, according to Great HealthWorks, the manufacturer of the supplement. There are 30 fatty acids in the supplement, including omega-3s such as DHA and EPA.
Omega-3 fatty acids, especially the ones derived from fish, contain certain substances that lower the amount of triglycerides in the blood, which may decrease an individual's risk of developing heart disease, as claimed by WebMD. This ability is specific to omega-3 DHA. A combination of omega-3's DHA and EPA may improve symptoms of rheumatoid arthritis by reducing joint pain and overall stiffness as well as by enhancing the potency of anti-inflammatory drugs.
The natural omega-3 fatty acids found in Omega XL are derived from green-lipped mussels, a clam the manufacturer freshly harvests in New Zealand, as stated by Great HealthWorks. The supplement comes in the form of a small gel capsule that contains no toxins, PCBs or other potentially harmful ingredients. The manufacturer claims to have proven the effectiveness of the supplement against joint pain and inflammation through over 30 years of clinical studies. The studies have also concluded that the supplement does not contain negative interactions with prescription drugs as is the case with other fish oil supplements.
