Guide To Turmeric Side Effects, Precautions, And Interactions

May Prevent Iron Absorption

High doses of turmeric may prevent iron absorption, and turmeric should be used with caution in patients who have an iron deficiency. Studies conducted in the laboratory and on animals suggest turmeric binds to iron, decreasing the body's ability to absorb iron from food. In theory, this could result in anemia in patients who are already mildly deficient in iron. While some human studies have concluded iron absorption was not affected by turmeric supplementation, most doctors advise patients to be careful about consuming large doses of turmeric if they have or are at risk for an iron deficiency. In fact, a case study from January 2019 reported that a sixty-six-year-old male developed an iron deficiency after consuming six turmeric extract capsules per day. Patients should ask their healthcare provider about a safe turmeric dose for their health needs, and they may also want to have their iron levels checked regularly. When consuming any amount of turmeric, patients may want to increase the amount of iron in their meals. Iron-rich foods such as lentils, chickpeas, peas, and soybeans may be beneficial, and some patients might need to take an over-the-counter iron supplement as well. Patients should check with their doctor before taking any type of supplement.
