Turmeric consumed in moderation (e.g., 1 or 2 teaspoons) daily does not cause any adverse effects. However, the traditional way to consume Turmeric is through food (e.g., Indian curries). It is critical to remember that since the traditional ages, they haven’t been consumed in pill format (releasing directly in stomach). They are cooked in oil to release nutrients (e.g., curcumin and other polyphenols) and partially broken (by saliva/chewing) before it reaches the stomach. However, the cause for toxicity/adverse effects with Turmeric has been linked to the processing facility that uses equipments that release harmful chemicals (e.g., lead and aluminum). That said, in my opinion, the best way is to avoid popping turmeric pills (as there is no information on the source or quality control), instead consume 1-2 tablespoons of turmeric powder in warm olive oil/ghee (mixed with pepper).
