Vitamins and Supplements You Should Never Mix

Iron and Green tea

While green tea isn’t a supplement, it is a delicious antioxidant-infused beverage that many of us enjoy for its health benefits. Unfortunately, taking iron supplements along with green tea isn’t a great mix.“Green tea can actually cause iron deficiency if taken in large quantities for longer periods of time,” says Dr. Tripathy. “Iron, on the other hand, can decrease the efficacy of green tea.”The solution? Skip green tea on days when you’re taking your iron supplement and decrease your weekly consumption.
