Research doesn't indicate the best time of day to take turmeric. Turmeric and turmeric supplements are generally well tolerated, however, there are some reports of nausea or diarrhea at high doses. To prevent side effects, taking turmeric at a time of day that you have a balanced meal would be best. You may experience nausea or gastrointestinal effects if you take high doses of turmeric on an empty stomach.If taking a supplement that has more than one capsule per serving, consider splitting the dose to take it with two different meals. Taking a dietary supplement at the same time every day may help you make it a part of your routine and help you remember your daily supplements.
