Maryland Doctor Shares Five Supplements to Clear Brain Fog

A Maryland-based doctor has shared five common supplements that can help people fight brain fog and improve mental clarity. Dr Kunal Sood posted the list on Instagram, noting that while a healthy lifestyle helps, these specific nutrients offer extra support for brain health.

Supplement List

Creatine is widely known for muscle growth, but it also helps the brain make cellular energy by regenerating ATP, which studies show can benefit working memory when people lack sleep. Omega-3 fatty acids like DHA and EPA build brain cell membranes and help control inflammation. Magnesium supports nerve function and energy, with early studies on magnesium L-threonate showing potential benefits for sleep and thinking, though evidence still varies by form. Vitamin B12 is crucial for nerve function and healthy red blood cells, meaning fixing a true shortage can cure fatigue and poor concentration, though extra doses do not help if levels are already fine. Finally, Vitamin D deficiency can cause tiredness, and treating that shortage can improve how some people think and feel.

Context

Brain fog is a general term for feeling confused, forgetful, or lacking mental focus, and it can stem from poor sleep, stress, or diet. While supplements are easily bought over the counter, medical experts generally advise checking with a doctor before adding them to a daily routine.
