Prof. Benjamin Murphy, Ph.D.Fish oil supplementation should be avoided in certain medical conditions, despite its numerous benefits. Blood-thinning properties may pose potential risks when surgery is performed. Allergic reactions to the proteins in fish or the fillers in the capsules lead to an immune response. Interactions of drugs such as blood thinners may lead to dangerous consequences. Contaminants in inferior brands may introduce toxins into the body.
Surgical Precautions
- Risk: Excessive bleeding during procedures
- Protocol: Stop 2 weeks pre-surgery
- Alternative: Switch to plant-based DHA
Allergy Management
- Symptom: Hives, swelling, or anaphylaxis
- Source: Fish proteins or synthetic additives
- Solution: Algal oil supplements
Medication Conflicts
- Drugs: Warfarin, aspirin, or clopidogrel
- Danger: Uncontrolled bleeding episodes
- Monitoring: Regular INR blood tests
Pre-surgical protocols specify discontinuation of fish oil two weeks before surgery. I've helped cardiology patients facilitate the transition using algal DHA. This plant-based extract offers omega-3 without the thinning properties. Be sure to inform your surgical staff of any supplements you are taking to ensure your safety and well-being.
Allergic responses frequently come from protein residues in inferior supplements. Symptoms may be swelling of the throat or rash. Brands subjected to testing by outside sources mitigate this risk. For individuals with severe allergies, it is recommended to consider switching to plant-based sources, such as flaxseed combined with algal oil.
Interactions with anticoagulants should be discontinued immediately. Fish oil can potentiate blood-thinning medications in a potentially dangerous way. Watch for blood in the urine or stool. I work with a pharmacist to change the timing of medication when it isn't possible to stop the medication.
Contaminant risks also include mercury and PCBs, which may be present in products regardless of testing. Look for supplements that show the IFOS 5-star certification. Krill oil is a purer form of omega-3 with the added benefit of astaxanthin protection. Store omega-3 oils in dark bottles to help prevent rancidity.
