• Immunosuppressants: Omega-3s may modulate immune responses, potentially interacting with immunosuppressive therapies.

Conclusion: If you are taking prescription medications, consult a healthcare provider before supplementing with fish oil.

Are There Any Side Effects of Taking Fish Oil?

Most people tolerate fish oil well, but some experience mild side effects, especially when starting supplementation. Common side effects and solutions:

• Fishy aftertaste or burps: Choose enteric-coated capsules or take fish oil with meals.
• Digestive issues (nausea, bloating, diarrhea): Start with a lower dose and gradually increase intake.
• Bad breath or body odor: Ensure fish oil is fresh and properly stored to prevent rancidity.
• Allergic reactions (rare): Those with seafood allergies should opt for algae-based omega-3 supplements.

Conclusion: Side effects are typically mild and can be managed by choosing high-quality fish oil and following proper dosing guidelines.

Is Fish Oil Safe for People with Seafood Allergies?

Individuals with seafood allergies may wonder if they can safely take fish oil supplements. Key considerations:

• Most allergic reactions to seafood come from proteins, not fats, so purified fish oil supplements typically do not cause allergic reactions.
• However, individuals with severe seafood allergies should exercise caution and consult a doctor before taking fish oil.
• Algae-based omega-3 supplements provide a safe, plant-based alternative.

Conclusion: While most people with seafood allergies tolerate purified fish oil, those with severe allergies may consider plant-based omega-3 sources.

How to Store Fish Oil Properly
