8 Brain Fog Supplements a Top Doctor Says Clear Your Thinking Fast
Whether you misplaced your keys, forgot where you parked your car or are having trouble recalling names, brain fog can quickly set in—especially during perimenopause and menopause—and make it hard to think clearly. The good news is that there are natural supplements for brain fog that may help you regain mental clarity. Keep reading as a top psychologist shares the best herbs and vitamins for sharpening focus and supporting brain health.
8 brain fog supplements to boost your focus
Focus is largely about the prefrontal cortex, the brain’s CEO, which is involved in attention, planning and follow-through, explains psychiatrist Daniel G. Amen, MD, author of Change Your Brain Every Day. “Brain fog is often a sign that something is ‘off,’ whether it’s poor sleep, hormonal imbalances, inflammation, head trauma or low blood flow,” he adds.
If you struggle to concentrate or find yourself easily distracted, these brain fog supplements can help sharpen your focus and cognitive performance:
Omega-3s
It’s no surprise omega-3 fatty acids appear on this list, as they’re shown to improve focus, he notes. Dr. Amen adds that they also improve brain cell communication and help us think more clearly.
Recommended daily dose: 900 to 2,000 mg of combined EPA and DHA omega-3 supplements daily.
Green tea extract (EGCG + L-theanine)
These antioxidant-rich compounds support healthy blood flow to the brain and enhance attention and mental clarity, which is especially important for older adults.
Recommended daily dose: 300 to 400 mg of EGCG and100 to 400 mg of L-theanine daily.
Rhodiola
This flower has been shown to improve learning and work performance, says Dr. Amen. That’s in part because it’s an adaptogen, balancing the stress hormones that impede focus even in otherwise healthy adults.
Recommended daily dose: 200 mg of rhodiola twice a day.
Ashwagandha
The adaptogenic herb promotes overall mental focus, notes Dr. Amen, by decreasing stress and lifting brain fog.
Recommended daily dose: 300 to 600 mg of ashwagandha daily.
Ginseng
Simply put, ginseng sharpens focus, he declares. That’s largely due to compounds in ginseng that dial down mental fatigue and boost blood flow to the brain.
Recommended daily dose: 200 mg to 400 mg of ginseng daily.
Zinc and iron (if deficient)
This duo is critical when it comes to fighting brain fog in the long term, because deficiencies are associated with inattentiveness and impulsivity, Dr. Amen notes. Consider talking to your doctor about getting tested for deficiencies—if you have a shortfall, they can recommend the right tailored dosage to your needs.
Lion’s Mane ‘smart’ mushrooms
“This supplement enhances key neural pathways to boost mental clarity,” shares Dr. Amen. Indeed, these mushrooms work by encouraging the growth of new brain cells.
Recommended daily dose: 500 to 1,000 mg of lion’s mane daily.
B-complex vitamins
This suite of vitamin supplements—especially B6, B12 and folate—supports energy production and brain metabolism, which are key to easing brain fog and improving concentration, notes Dr. Amen.
Recommended daily dose: Follow package directions, as B-complex formulations vary. Look for a formula that includes B6, B12 and folate.
The bottom line on brain fog supplements
Brain fog doesn’t have to slow you down. These eight science-backed supplements support healthy blood flow, reduce stress, boost brain cell communication and fill nutritional gaps that cloud your thinking.
