What is curcumin?

Curcumin is the principal curcuminoid found in turmeric (Curcuma longa), the golden-orange root used in South Asian cuisine and Ayurvedic medicine.

Turmeric has been used traditionally for thousands of years, while curcumin has become a major focus of modern research. Curcumin typically makes up around 2 to 5% of dried turmeric root.

Whole turmeric provides curcumin alongside other plant compounds and has an important culinary role. Concentrated curcumin extracts provide a more standardised amount of this specific compound.

Anti-inflammatory activity and joint comfort

Curcumin’s anti-inflammatory properties are among its most extensively researched effects. It influences several molecular pathways involved in your body’s inflammatory processes.

Research has examined its effects on NF-κB, COX-2 and various inflammatory cytokines. These mechanisms have contributed to interest in curcumin for supporting your joint comfort and mobility.

Clinical trials have investigated standardised curcumin extracts for joint health, with some reporting improvements in comfort and flexibility. Curcumin is generally well tolerated when used as directed.

Antioxidant protection and liver support

Curcumin also has antioxidant properties that have attracted considerable research interest. It can help neutralise free radicals and influence your body’s natural antioxidant defence systems.

Research has examined curcumin’s effects on antioxidant enzymes such as superoxide dismutase and glutathione peroxidase. These properties may help protect your cells from oxidative stress.

Curcumin has also been studied for its potential effects on liver function and bile production. However, more research is needed to understand how these effects translate into practical benefits.

The bioavailability challenge

Curcumin has naturally low bioavailability, meaning your body absorbs relatively little when you consume standard forms. Much of the compound is metabolised before it reaches your bloodstream.

This has led to several enhanced absorption formulations. Piperine from black pepper can increase curcumin absorption by slowing its breakdown in your digestive tract and liver.

Phospholipid formulations, such as curcumin phytosomes, can also improve absorption by increasing curcumin’s solubility. Micellar and nanoparticle formulations use different approaches to improve how readily your body absorbs curcumin.

When choosing a curcumin supplement, check whether it uses an enhanced absorption technology. Also consider the amount and type of curcumin provided per serving.
