Brain Health Supplements: US doctor recommends these 5 must-have supplements for a healthy brain

Nootropics are a mix of vitamins, fats, amino acids, and herbs designed to support cognitive function. These supplements can help with focus, mental clarity, mood regulation, and even better sleep.

Dr Sandison told CNBC Make It, that she takes nootropics on days when she needs to be extra focused, such as during public speaking or high-workload days. They are known to improve productivity and energy levels, making them useful for people with demanding schedules. However, it’s essential to consult a doctor before taking them, especially if you are on other medications, as they may interact with psychiatric drugs.
