As a doctor specialising in neurocognitive medicine and the founder of a brain optimisation clinic in California, Heather Sandison has spent 15 years studying the brain, and she believes that it is important to address nutritional deficiencies to ensure a healthy functioning brain.

"Nearly every patient I see leaves with a list of recommended supplements," she told CNBC Make It, sharing the details of three supplements that Sandison said she recommends "to just about everyone". The doctor, however, suggested getting the supplements checked by a healthcare provider first to discuss if "they are appropriate for you, dosages and possible interactions with any medications you may be taking".

"Some nutrients and herbs can interact with prescribed medications in potentially dangerous ways, such as nootropics and mood-stabilising psychiatric medications," Sandison clarified.

1.) Nootropics

It is a fancy word for a substance that supports cognitive function and typically includes a blend of vitamins, fats, amino acids, herbs, and sometimes caffeine. "My personal experience with nootropics is that they help with focus, mental clarity, mood and better-quality sleep. It can give you a level up on days that you haven’t gotten enough rest or eaten well," Sandison told the publication. "I take them on days I’m giving talks or when I have a lot of work to get through and need to be on all day — they help me power through, feel productive and sleep better at night."

2.) Vitamin D with K

"These fat-soluble vitamins have roles all over the body, particularly in maintaining bone health, but they are also directly related to brain health," the brain expert said. "Vitamin K works with D to direct calcium into the bones. Like vitamin D, having higher levels of circulating vitamin K is associated with better cognitive function."

3.) Omega-3

Omega-3 essential fatty acids are anti-inflammatory and are believed to help reduce neuroinflammation and heart disease risk. "What’s good for the heart is also good for the brain," Sandison said.
