Four turmeric interactions that may pose health risks

Many people use turmeric to support health and reduce inflammation, but it can interact with some medications and supplements, making caution necessary, especially for those with chronic conditions.

Doctors advise caution with turmeric and blood thinners, as curcumin may have an effect. Taking turmeric supplements alongside anticoagulant medications or certain supplements—such as garlic, ginkgo, or high doses of vitamin E—could increase the risk of bleeding. However, the strength of evidence varies depending on the substance and dosage, and these possibilities do not mean that all combinations will necessarily cause bleeding, according to Al Arabiya.

Turmeric can also affect blood sugar levels, raising the risk of excessively low blood sugar when combined with some diabetes medications. It is important to watch for symptoms such as trembling, sweating, dizziness, and confusion, and to consult a doctor before adding turmeric supplements, especially for those taking medications that may cause hypoglycemia.

Some turmeric supplements, particularly highly absorbable formulations, have been linked by doctors to rare cases of liver injury. Taking these supplements with other products that may harm the liver, such as concentrated green tea extract or kava, requires extra caution. Using turmeric in typical food amounts is generally not associated with the same risks.

Evidence also suggests that curcumin may reduce iron absorption. This could be significant for people with iron deficiency, anemia, or those relying on supplements to address deficiencies. In such cases, it is best to consult a doctor before regularly taking turmeric supplements.
