US doctor suggests 3 drinks that can help sharpen memory

When it comes to memory, most people think of brain games, supplements, or meditation. But sometimes, even the smallest daily choices—like what goes into a morning cup—can quietly shape cognitive health. A US based neuroscientist, Robert WB Love, describes about drinking these three drinks everyday and watch the changes it makes in our body. These drinks, when consumed in required quantities, can nourish the brain, improve focus, and support memory retention over time.


Each of these drinks brings a unique set of compounds that protect neurons, support brain energy, and even calm inflammation, one of the key factors behind mental fog and forgetfulness. Here's what they are and how they help.



Green tea

Green tea has earned its place as one of the most respected drinks for brain health. Light and earthy in flavour, it holds powerful ingredients like L-theanine and EGCG (epigallocatechin gallate). L-theanine is known to promote a calm, focused mind, without the jitteriness that strong stimulants sometimes bring.


What makes green tea stand out is its ability to enhance attention and memory simultaneously. The small amount of natural caffeine present works in harmony with L-theanine to improve reaction time and working memory, according to findings published in a journal.


Also, EGCG—an antioxidant found almost exclusively in green tea—has shown potential to protect the brain from oxidative stress, which plays an important role in cognitive decline. It’s a drink that not only energises the body but also gently supports mental clarity over time.

Organic coffee with MCT oil

Coffee, often misunderstood, can be a brilliant ally for the brain when sourced right and consumed consciously. Organic coffee, free from pesticides and synthetic additives, offers cleaner caffeine and a natural lift in mental energy. But when blended with MCT oil (medium-chain triglycerides), it becomes something even more powerful.


MCT oil, derived from coconut or palm kernel oil, gets converted quickly into ketones—an alternative energy source for brain cells. These ketones have been found to improve memory function, especially in those facing early signs of cognitive decline. A study found that MCT supplementation improved cognitive performance in older adults with memory concerns.


This combination not only sharpens focus but also provides sustained mental energy, reducing the common midday crash. Many individuals following brain-boosting routines now swear by this smart blend for enhanced clarity and productivity.



Magnesium-rich water

Magnesium rarely gets the spotlight it deserves, but it plays a key role in brain function. Low magnesium levels have been associated with forgetfulness, mental fatigue, and even a higher risk of age-related cognitive conditions.


Drinking distilled or reverse osmosis (RO) water is common for purity, but these processes also remove beneficial minerals, including magnesium. Re-mineralising this water with a magnesium supplement or drops can restore what’s missing.


Magnesium supports neuroplasticity, the brain’s ability to form and reorganise neural connections. It also helps regulate glutamate, a neurotransmitter deeply involved in learning and memory. As per a study, maintaining magnesium levels may help reduce the risk of neurodegenerative diseases like Alzheimer's.


Hydrating with magnesium-enriched water can be a simple, daily way to support long-term cognitive health, especially when paired with a balanced diet.

Why these drinks matter more than just a trend

What connects green tea, MCT-infused organic coffee, and magnesium-rich water is not just their popularity, but their biological impact on the brain. Each one brings a targeted benefit: green tea calms while keeping the mind alert, coffee with MCT energises without the crash, and magnesium water supports brain repair and function at the cellular level.
