Cognitive function encompasses the brain’s ability to process, store, and retrieve information efficiently. It includes essential skills such as focus, logic, memory, and creativity. Maintaining optimal cognitive function is vital for daily activities and long-term mental health. Cognitive function can be supported by herbs like ginkgo (Ginkgo biloba), lion’s mane mushroom (Hericium erinaceus), and bacopa (Bacopa monnieri), which enhance brain health by improving blood flow, promoting neuroprotection, and reducing oxidative stress. Adequate sleep, hydration, and mental stimulation also play critical roles in maintaining cognitive function.
