A traditional Korean pantry staple is getting a neuroscience rebrand. Ganjang - fermented soy sauce - is now being studied for its potential to enhance brain function. Recent research from Switzerland shows ganjang consumption improved memory performance and gut microbiota in mice. Broader literature supports a link between fermented foods and the gut-brain axis, fueling a new wave of cognitive-focused food innovation. With the global fermented soy sauce market currently worth US$3.12B and projected to grow steadily through 2033, this low-key condiment may be the next unlikely hero of food-based nootropics.
Key Drivers:
Rising consumer demand for functional foods supporting mood, focus, and cognition
Increased scientific interest in traditional ferments and neuroinflammation modulation
Asian market leadership in gut-health-forward food innovation
