Various clinical tests carried out on turmeric deem it to be generally safe for regular use. In determining the appropriate turmeric dosage to take on a daily basis though, it is preferable to take it in moderation. A concentrated dose of 50 mg to 100 mg can be quite sufficient if taking a turmeric supplement or a turmeric capsule. Dietary supplements may not be necessary if turmeric is made part of the normal diet; a few pinches of it can be added to vegetables, soups, casseroles, rice and other foods during cooking.

If taken in excess, there may be some side effects such as nausea and stomach upsets. A more major problem with taking turmeric in high amounts is that it acts as an anti-coagulant, that is, it prevents the blood from clotting in the event of an injury. Too much curcumin in the system may prevent wounds from healing fast, cause intestinal bleeding, and lead to further health complications.

Another issue to bear in mind is the chelating activity of turmeric. Turmeric dosage in moderate amounts can help the body get rid of a toxic excess of metals like iron and copper. If overdone, the chelating agents can impede the iron metabolic process, resulting in iron deficiency and anemia.
