Recommended Dosage of Turmeric Supplements

A popular cooking spice, turmeric also has a long history of use as a medicine. It contains a substance called curcumin, which appears to account for its therapeutic effects. The University of Maryland Medical Center reports that research has shown it might help treat a variety of conditions, ranging from cancer to digestive distress, but not all studies have found positive results. The optimal dose of turmeric will depend on your reason for using it. A doctor well-versed in alternative medicine can offer guidance on an appropriate dose and other aspects of safe use.

General Dosing Guidelines

Supplemental turmeric comes in many forms. The Beth Israel Deaconess Medical Center notes turmeric supplements standardized to contain a certain amount of curcumin – typically 90 to 95 percent -- are the most common for medicinal purposes. It notes a standard dose usually falls between 400 mg to 600 mg three times a day, though some conditions might require larger doses.

The University of Maryland Medical Center notes the following typically recommended daily doses for other forms of turmeric: cut root: 1.5 to 3 g; dried, powdered root: 1 g to 3 g; fluid extract: 30 to 90 drops; tincture: 15 to 30 drops four times a day.
