There’s no shortage of health claims about curcumin, the active ingredient in turmeric. But what does the research say?

“Curcumin is a natural antioxidant that has anti-inflammatory benefits, as well as [possible] benefits related to slowing the aging process and preventing Alzheimer's disease and, potentially, depression,” says Elizabeth Ann Shaw, RDN, the owner of Shaw Simple Swaps Consulting in San Diego.

Unfortunately, turmeric (and curcumin on its own) doesn’t absorb well into the bloodstream, and having it in curry once a month is unlikely to give you the desired anti-inflammatory and antioxidant benefits, says Dana Angelo White, RD, the owner of Dana White Nutrition. To reach the amounts of turmeric and curcumin shown to offer benefits in research studies, you’ll have to turn to supplements. It is important to note, however, that the U.S. Food and Drug Administration (FDA) has no established safe or recommended daily value for curcumin or turmeric, and the FDA does not regulate any supplements.

Still, more research is needed to determine if curcumin is a safe and effective long-term treatment strategy for people with heart disease.

Thanks to its anti-inflammatory, antimicrobial, and antioxidant properties, turmeric may be an effective treatment for a variety of skin conditions, including acne, eczema (atopic dermatitis), photoaging, and psoriasis. Yet robust research is lacking.
