Omega-3 fish oil 1200 mg capsules are excellent for supporting overall health. They are primarily used to promote heart health by lowering triglycerides and managing blood pressure, as well as reducing joint stiffness and supporting brain function. These capsules are generally very safe and well-tolerated. Some people may experience mild, harmless side effects like a fishy aftertaste, burping, or slight stomach upset. Because omega-3s can mildly thin the blood, it is always a good idea to consult your doctor before starting them, especially if you take blood thinners or have upcoming surgeries.
