What vitamins and supplements thin the blood?
Also, you have to watch your supplement intake while on common blood thinners, as some vitamins and herbs (such as vitamin E, aspirin, or Ginkgo biloba) can thin your blood too much. If you're on a blood thinner, limit supplemental vitamin E to 400 IU per day, and avoid taking aspirin or Ginkgo biloba.
Herbals Known to Have Blood-thinning Properties and That May Interact with Blood Thinners*

- Many side effects of too much vitamin D are related to excessive calcium in the blood. However, these symptoms don't occur in everyone with elevated calcium levels. Summary: High-dose vitamin D therapy has been found to cause nausea, vomiting and lack of appetite for some due to high blood calcium levels.
- If you are a heart patient who is taking blood thinners, such as warfarin (Coumadin®), you need to be careful not to overdo vitamin K. Blood thinners are often prescribed for people at risk for developing harmful blood clots. It can actually decrease the effect of warfarin.
