Curcumin

Studies in people

• Benefit

  Metabolic disorders²

  Curcumin, found in turmeric, may help with metabolic problems like fatty liver and heart disease.

• Benefit

  Blood sugar and cholesterol³

  Curcumin with piperine may improve blood sugar, cholesterol and inflammation, but scientists say more good trials are needed.

• Benefit

  Memory and muscle in aging⁴

  In older adults, curcumin may help memory, brain health and muscle, but scientists do not yet know the right amount.

• Benefit

  Bone health in women⁵

  In women with thin bones, curcumin supplements improved bone density, but human studies on curcumin and bone health are still few.

• Benefit

  Joint pain and stiffness⁶

  In people with osteoarthritis, curcumin eased joint pain and stiffness, with fewer side effects than painkillers.

• Benefit

  Muscle soreness after exercise⁷

  In studies of active adults, curcumin seemed to ease muscle soreness and pain after hard exercise.

• Concern

  Kidney, heart and liver effects⁸

  Some case reports link too much curcumin to problems with the kidneys, heart, liver, blood and immune system.

• Benefit

  Blood sugar in diabetes⁹

  In people with type 2 diabetes, curcumin lowered fasting blood sugar, long-term blood sugar and inflammation markers.

• Open question

  Muscle recovery after exercise¹⁰

  In men, higher doses of curcumin eased soreness and blood markers but slowed muscle endurance recovery at 24 hours.

• Benefit

  Blood fat levels¹¹

  In people with metabolic syndrome, curcumin lowered blood fats but did not change blood pressure, blood sugar or weight.

• Benefit

  Heart and blood vessel risk¹³

  In people with type 2 diabetes, curcumin lowered blood pressure and LDL cholesterol and improved heart risk scores.

• Benefit

  Muscle and joint comfort¹⁴

  In postmenopausal women, curcumin capsules improved musculoskeletal health scores and reduced fatigue over 8 weeks, but not depression.

• Benefit

  Migraine symptoms¹⁵

  In people with migraines, phytosomal curcumin reduced how bad, long and often headaches were, and improved sleep.

Study type not stated

• Open question

  How much the body absorbs¹⁸

  Curcumin is poorly absorbed when eaten, so scientists are still working out how to get more into the body.

Found in some samples or products

These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.

• What's actually in the capsule¹⁶

  Curcumin levels in turmeric capsules varied widely, and some contained trace metals like lead and nickel.

Single cases of misuse or overdose

One person or one incident, such as an accidental overdose or a mistake in a kitchen or factory. They are real, but a single case does not show what happens at normal amounts, so the signal does not count them.

• Recurrent liver damage¹²

  A woman's liver injury came back worse after she took turmeric with black pepper again.

How it’s made and used

• Main yellow component¹⁷

  Curcumin is the main yellow part of turmeric, and food is still its main use.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
