Omega XL Side Effects
The green-lipped muscle is the source of omega XL.

Omega XL is a fish oil supplement with a mixture of omega-3 fatty acids. Specifically, omega XL is from the green-lipped mussel from New Zealand, part of the shellfish family. Omega-3 fatty acids play a role in normal growth and development. According to the University of Maryland Medical Center, they may help to lower the risk of heart disease, cancer and arthritis. Before taking any supplements, consult with your health care provider.

Gastric Upset

Omega XL fish oil may cause abdominal bloating and gas. This side effect is more bothersome than an adverse affect. This may be experienced when initiating large doses. The Mayo Clinic advises you to start with small doses and not switch brands. Belching may be experienced with gastric upset. This may lead to a fishy taste in the mouth. Freezing fish oil supplements before you take them may help to avoid this side effect. If these symptoms persist, consult a health-care provider.

Shellfish Allergy

The OmegaXL website claims the proteins that cause shellfish allergies have been removed from the green-lipped mussel. But, if you do have an allergy to shellfish, consult your health care provider before using this product. This type of allergy can have minor side effects such as a skin rash. Adverse reactions can be swelling of the throat and difficulty breathing. These side effects would require immediate medical attention.

Increased Bleeding

Increased bleeding time means you could bruise and bleed easily if taking higher doses of omega-3. There is a lower significance of this side effect when taking lower doses. A person may initially have a minor nose bleed or more bruises on the skin. Should this occur, your health care provider should be notified. The Food and Drug Administration reports dosing up to 3 g of omega-3 a day is safe.
