What Should You Not Take With Omega-3,6,9 Supplements?

3 min read

According to the National Institutes of Health, high doses of omega-3s can increase bleeding risk when taken with certain medications. Understanding what you should not take with omega-3,6,9 supplements is critical for preventing adverse health outcomes and ensuring your safety.

Quick Summary

This guide details important drug, supplement, and food interactions to be aware of when taking omega-3,6,9, including blood thinners and blood pressure medications. Key safety precautions and a comparison table of interactions are provided.

Key Points

  • Blood Thinners: Avoid high doses of omega-3 with prescription anticoagulants like warfarin, aspirin, and NSAIDs to prevent excessive bleeding.

  • Blood Pressure Meds: If you take medication for high blood pressure, consult a doctor before using omega-3, as the combination can cause your blood pressure to drop too low.

  • Orlistat: This weight-loss drug can inhibit the absorption of omega fatty acids, so take them at separate times during the day.

  • Cod Liver Oil: Be cautious of high Vitamin A content in cod liver oil, as high doses can lead to toxicity over time.

  • Certain Herbs: Herbal supplements with blood-thinning properties, such as garlic and ginkgo biloba, should be used with caution alongside omega-3s.

  • Oral Contraceptives: Some birth control pills may reduce the effectiveness of fish oil's triglyceride-lowering effects.

Important Interactions to Know Before Taking Omega-3,6,9

Omega-3,6,9 supplements are widely consumed for their potential benefits, including supporting heart and brain health. However, these fatty acids can interact with several medications and other supplements, potentially leading to harmful side effects. It is crucial to consult a healthcare provider before adding these supplements to your regimen, especially if you are taking other medications.

Medications That Increase Bleeding Risk

Perhaps the most critical interaction to be aware of is with blood-thinning agents. High doses of omega-3 fatty acids naturally have antiplatelet effects, meaning they can slow down blood clotting. When combined with prescription blood thinners, this effect can be amplified, significantly increasing the risk of bruising, nosebleeds, and excessive bleeding, especially before surgery.

  • Prescription Anticoagulants: This includes medications like warfarin (Coumadin), apixaban (Eliquis), and rivaroxaban (Xarelto). The combination can make the blood too thin, requiring close medical supervision and potential dose adjustments.
  • NSAIDs: Regular or high-dose use of Nonsteroidal Anti-Inflammatory Drugs like ibuprofen and aspirin can increase bleeding risk in the gastrointestinal tract. Combining them with omega-3 supplements can compound this risk, particularly in high doses.
  • Herbal Supplements: Certain herbs are also known to have blood-thinning properties. Taking omega-3 with supplements like garlic, ginger, ginkgo biloba, and dong quai can further increase the risk of bleeding.

Blood Pressure Medications

Omega-3 supplements can cause a modest reduction in blood pressure. For individuals already taking antihypertensive drugs to manage high blood pressure, combining these can lead to an excessive drop in blood pressure, a condition known as hypotension. Close monitoring is necessary to prevent dizziness, lightheadedness, and other related complications. Types of blood pressure medications to be mindful of include:

  • ACE inhibitors
  • Beta-blockers
  • Diuretics

Other Prescription and Over-the-Counter Drugs

Beyond blood pressure and bleeding, other medication interactions exist:

  • Oral Contraceptives: Some birth control pills may interfere with the triglyceride-lowering effect of fish oil, potentially reducing its effectiveness.
  • Orlistat: This weight-loss drug can hinder the absorption of fat-soluble vitamins and fatty acids. It is recommended to take your omega-3 supplement at least two hours apart from orlistat to ensure proper absorption.
  • Immunosuppressants: Medications like cyclosporine, sirolimus, and tacrolimus can have their levels increased in the body when taken with fish oil, potentially amplifying their effects and side effects.

Other Supplements and Dietary Considerations

It's not just prescription drugs that pose a risk. Several other factors should be considered when supplementing with omega-3,6,9.

  • Vitamin E: While often paired to prevent oxidation of omega-3s, very high doses of Vitamin E can also have blood-thinning effects. The combination should be monitored, especially in individuals with bleeding risks.
  • Cod Liver Oil: This specific type of fish oil is high in Vitamin A and D. Excessive intake can lead to Vitamin A toxicity, causing symptoms like nausea, dizziness, and joint pain. Always check the Vitamin A content on your supplement label.
  • High-Mercury Fish: While supplements typically have contaminants removed, consuming large amounts of high-mercury fish can be risky. If you get your omega-3s from diet, be mindful of intake limits for fish like swordfish and king mackerel.

Comparison Table of Omega Fatty Acid Interactions

Interaction Type Potential Side Effects Specific Examples
Increased Bleeding Excessive bruising, nosebleeds, internal bleeding Warfarin, Eliquis, Ibuprofen, Aspirin, Ginkgo Biloba
Lowered Blood Pressure Dizziness, lightheadedness, excessive pressure drop ACE Inhibitors, Beta-Blockers, Diuretics
Reduced Absorption Decreased effectiveness of omega fatty acids Orlistat (take 2 hours apart)
Hormonal Interference Reduced triglyceride-lowering effect Oral Contraceptives
Increased Drug Levels Heightened effects and side effects of medication Cyclosporine, Sirolimus, Tacrolimus
Vitamin Overload Nausea, headache, joint pain High-dose Cod Liver Oil (Vitamin A)
Immune System Suppression Lowered immune response Higher doses of omega-3 in immunocompromised individuals

Conclusion

While omega-3,6,9 supplements offer significant health benefits, they are not without risks, particularly when combined with other substances. The most critical concerns involve increased bleeding risk with anticoagulants and blood-thinning medications, as well as an excessive drop in blood pressure with antihypertensive drugs. Other supplements like certain herbs and even high-dose Vitamin E can also play a role. Ultimately, the best course of action is to have an open and honest conversation with a healthcare professional before starting any new supplement regimen to ensure it aligns with your overall health profile and current medications. This informed approach can help you safely reap the rewards of these powerful fatty acids.
