It adds flavor to our curries, turns our smoothies golden, and sits proudly in our kitchen cupboards. But could turmeric also be good for our brains? Scientists are seriously investigating this question, and their findings are intriguing, to say the least. Between scientific promises and important nuances, here’s what we really know about this spice that’s been touted as a superfood.
What curcumin actually does in your brain
The star ingredient in turmeric is curcumin. This molecule has attracted the attention of researchers for several years, and in March 2025, the journal *Biotechnology Advances* published a review that has generated considerable discussion.
The researchers focused in particular on certain proteins involved in brain aging. Their findings? Curcumin possesses anti-inflammatory properties that may help slow down certain mechanisms associated with cognitive decline. Nutritionist Molly Knudsen confirms this: chronic low-grade inflammation contributes to brain aging, and curcumin may play a protective role in this process.
Another fascinating avenue of research is the gut-brain axis. Gut bacteria convert curcumin into various compounds, some of which are thought to have antioxidant and anti-inflammatory effects. In short, your gut flora may amplify the benefits of this golden spice. Pretty encouraging, right? Memory and turmeric: promising results, but these should be put into perspective.
A study conducted at the University of California, Los Angeles, followed adults with mild memory problems for eighteen months. Participants took 90 mg of curcumin twice daily. The result? Their memory and mood improved more than in the placebo group.
Other studies, conducted over approximately twelve weeks, also suggest improved ability to remember information and a reduction in mental fatigue. Yet another reason to splurge on plenty of water!
But be warned: these studies involve small groups and use concentrated, standardized extracts, not just a pinch in a dish. Therefore, we cannot claim that seasoning your rice is enough to boost your brain power. Science is evolving, but caution is still advised.
How to consume turmeric wisely
The first thing to keep in mind is that curcumin is naturally poorly absorbed by the body, which is why many supplements combine it with piperine, a compound found in black pepper, to optimize its absorption.
Molly Knudsen makes it clear: If you choose an optimized dietary supplement, you should always choose the lowest possible dose. According to US health authorities specializing in complementary medicine, highly concentrated formulations have sometimes been linked to negative liver effects.
The good news? The simplest solution is often the best. Incorporating turmeric as a spice into a varied and balanced diet is a safe and enjoyable approach. Think of the famous golden latte, winter soups, roasted vegetables… The possibilities are endless!
However, high-dose supplements require medical advice, especially if you are undergoing treatment or are pregnant.
Turmeric may not be the fountain of youth, but it certainly deserves a prominent place in our kitchens – and in our wellness routine.
