2. Change in Dietary Habits: Individuals who regularly consume fatty fish or other omega-3-rich foods may decide to stop taking fish oil supplements. If they believe they can obtain sufficient omega-3 fatty acids through their diet alone.

3. Financial Considerations: Fish oil supplements can be relatively expensive, and some individuals may discontinue their use due to budgetary constraints or changes in financial circumstances.

5. Joint Discomfort: Omega-3 fatty acids have been studied for their potential benefits in reducing joint pain and inflammation, particularly in conditions like rheumatoid arthritis. Ceasing fish oil supplementation may lead to a temporary increase in joint discomfort in individuals who rely on these supplements for symptom management.
