                                While omega-3 fatty acids can enter the bloodstream within hours of taking a supplement, the health benefits of fish oil are not immediate and require consistent, long-term use. It is not a quick fix like aspirin for a headache, as the fatty acids need time to build up in tissues throughout the body to have a therapeutic effect. The answer to "how long does it take for fish oil to start working?" depends on the individual's health goals and their consistent daily intake over a period of weeks to months.
