Turmeric, the spice that gives curry its yellow color, has been a staple in traditional medicine in Asia for thousands of years. However, it has only recently started gaining popularity in the Western world for its purported health benefits.

One of the proposed benefits of turmeric is its potential effect on memory, but what does science say about this claim?.

What is Turmeric?

Turmeric is a spice derived from the root of the Curcuma longa plant, which belongs to the ginger family.

It has been used in traditional medicine in India, China, and other parts of Asia for thousands of years, primarily for its anti-inflammatory, antioxidant, and antibacterial properties.

The Active Ingredient in Turmeric

The active ingredient in turmeric is curcumin, which is responsible for its vibrant yellow color. Curcumin is a powerful antioxidant and anti-inflammatory agent and is thought to be responsible for many of the health benefits associated with turmeric.

Effects on Memory: Scientific Evidence

Multiple studies have investigated the potential cognitive benefits of curcumin in humans.

One study published in the American Journal of Geriatric Psychiatry found that a daily dose of curcumin (90mg) over the course of 18 months improved memory and attention in adults with mild memory loss and reduced amyloid deposits in the brain, which are associated with Alzheimer’s disease.

Another study published in the Journal of Psychopharmacology found that a single dose of curcumin (400mg) improved working memory and mood in healthy adults aged 60–85 years.

Similarly, a study published in the Journal of Psychopharmacology found that a daily dose of curcumin (400mg) over the course of four weeks improved memory and attention in healthy adults aged 60–85 years.

Mechanism and Bioavailability of Curcumin

The mechanism behind the potential cognitive benefits of curcumin is not completely understood.

However, it is believed that curcumin’s antioxidant and anti-inflammatory properties may play a role in protecting the brain from oxidative stress and inflammation, which are both believed to contribute to cognitive decline.

However, one major challenge with curcumin as a potential cognitive enhancer is its bioavailability. Curcumin is poorly absorbed by the body and rapidly metabolized, meaning that it may not reach therapeutic levels in the brain even at high doses.

Conclusion

The research on the effects of turmeric on memory is promising, with multiple studies suggesting that curcumin may provide cognitive benefits in certain populations.

However, the mechanism behind these potential benefits and the optimal dosing regimen is not yet fully understood, and the poor bioavailability of curcumin is a significant obstacle to its use as a cognitive enhancer. Nonetheless, there is certainly potential for future research on the cognitive benefits of turmeric and its active ingredient, curcumin.
