More Information ⬇️
⚡ Creatine
Creatine helps buffer brain energy through the creatine-phosphocreatine system, supporting ATP availability during periods of high cognitive demand. Studies suggest possible improvements in memory, processing speed, and attention, particularly when the brain is under metabolic stress (PMID: 37368234; 33578876; 39070254).
🐟 Omega-3s
DHA and EPA support neuronal membranes, synaptic signaling, and inflammatory regulation. They may be most helpful when low omega-3 intake, inflammation, mood symptoms, or mild cognitive decline contribute to brain fog (PMID: 36381743; 27933449; 36637075).
🩸 Vitamin B12
B12 is essential for myelin, nerve function, and red blood cell production. Replacing B12 can improve cognitive symptoms when true deficiency is present, but it has not been shown to improve cognition in people with normal B12 levels (PMID: 32206454; 31963141; 18350363).
🧂 Magnesium
Magnesium supports energy metabolism, NMDA receptor regulation, sleep, and stress physiology. It may help mental clarity when brain fog overlaps with poor sleep, headaches, stress, or low magnesium intake, although evidence remains indirect (PMID: 36613667; 39387051; 40647320).
🍄 Lion’s mane
Lion’s mane contains compounds being studied for neurotrophic and neuroprotective effects. Human studies are promising but mixed, so it is best viewed as an experimental cognitive support supplement rather than a proven treatment (PMID: 37958943; 18844328; 31413233; 38004235).
💡 Takeaway
These supplements may support mental clarity in specific situations, but persistent brain fog deserves evaluation for causes such as sleep disorders, anemia, thyroid disease, B12 deficiency, medication effects, depression, or post-viral illness. Discuss with your doctor prior to starting any supplement.
