Alternative medicine practitioners tout apple cider vinegar as a panacea for everything from weight loss and diabetes to diarrhea and constipation. They sometimes forget to mention the potentially serious side effects of this supplement, which is sold in both liquid and pill form. Apple cider vinegar could have blood-thinning properties which could cause excessive bleeding if you already take prescription blood thinners or over-the-counter medications such as aspirin. Ask your doctor before taking apple cider vinegar as a supplement.
Apple cider vinegar's blood-thinning effects have not been studied or proven in clinical trials. In fact, very few of apple cider vinegar's claims have been studied in well-designed clinical studies, according to eMedTV. Most of the information available on this supplement comes from anecdotal evidence, testimonials given by people who have used it.
Apple cider vinegar could increase spontaneous bleeding or bruising and could cause serious blood loss during surgery. Apple cider vinegar has in several documented cases damaged the esophagus, the tube that leads from your mouth to your stomach, because of its high acid content. Make sure to drink plenty of water if you take either apple cider pills or liquid supplements. The high acid content could also damage tooth enamel. Unpasteurized apple cider vinegar could also contain dangerous bacteria that could cause infection.
Interactions With Other Medications
Apple cider vinegar could increase bleeding if you take it with other known blood thinners. While prescription medications such as heparin and warfarin are best known for their blood-thinning effects, over-the counter medication and supplements can also possess blood-thinning properties.This can include a number of herbs such as capsicum, chamomile, feverfew, ginkgo biloba, garlic, ginger, licorice root and passionflower. Vitamin E and omega-3 fatty acids can also increase bleeding.
A study was conducted by researchers from the University of Arkansas after reports of esophageal injury in eight people taking apple cider vinegar tablets. It found considerable discrepancy in the actual amount of apple cider vinegar in the pills based on acid content and pH, according to a report published in the July 2005 "Journal of the American Dietetic Association." If you decide to try apple cider vinegar after talking to your doctor, buy only from well-known manufacturers.
