Coumadin and Dietary Supplements

When taking Coumadin, it is crucial to be cautious of interactions with dietary supplements. Certain supplements can affect the effectiveness of Coumadin and increase the risk of bleeding or clotting. Here are some key points to consider:

Fish oil: Fish oil supplements contain omega-3 fatty acids, which have blood-thinning properties. When combined with Coumadin, they can increase the risk of bleeding. Monitoring your intake of fish oil and discussing it with your doctor is recommended.
Ginkgo biloba: Ginkgo biloba is a popular herbal supplement used for memory and cognitive function. However, it can also affect blood clotting and interact with Coumadin, leading to an increased risk of bleeding. Consult your healthcare provider before taking ginkgo biloba while on Coumadin.

According to a study published in the Journal of Thrombosis and Haemostasis, interactions between Coumadin and dietary supplements are a significant concern for healthcare professionals and patients. The study highlights the importance of discussing all supplements with your healthcare provider to avoid potential adverse effects.
