Have you ever walked into a room and forgotten why you were there? Struggled to recall a familiar word during a conversation? Read the same paragraph three times because your mind kept wandering? Me too!
Many women over 40 begin noticing subtle changes in memory, concentration, and mental clarity. While these experiences can be worrisome, they don't necessarily mean you're developing dementia. In many cases, they're a normal part of the hormonal transition that occurs during perimenopause and menopause.
Estrogen plays an important role in brain function, influencing memory, attention, and communication between brain cells. As estrogen levels begin to fluctuate and eventually decline, many women experience what is commonly referred to as "brain fog." Poor sleep, chronic stress, thyroid disorders, insulin resistance, nutrient deficiencies, depression, anxiety, and certain medications can all make these symptoms even worse.
That said, several supplements have shown promising evidence for supporting brain health. While none can prevent dementia or completely eliminate brain fog, they may provide an added boost when combined with hormone balance and healthy lifestyle habits.
1. Omega-3 Fatty Acids
If I had to choose just one supplement for long-term brain health, omega-3 fatty acids would be high on the list. The omega-3 fat DHA is a major structural component of the brain, helping maintain the integrity and flexibility of brain cell membranes. EPA also plays an important role in regulating inflammation, which has increasingly been linked to cognitive decline. Some studies suggest that individuals with higher omega-3 intake may experience slower cognitive aging and better memory, particularly if they don't regularly consume fatty fish.
Aim to eat fish such as salmon, sardines, trout, or mackerel at least twice per week. If that's not realistic, a high-quality fish oil supplement providing both EPA and DHA may help fill the gap. I take 1300 mg of EPA/DHA daily.
2. Creatine
Your brain is one of the most energy-hungry organs in your body. Creatine helps regenerate ATP—the primary energy source used by every cell, including brain cells. Researchers have found that creatine supplementation may improve working memory, mental fatigue, and cognitive performance, particularly during periods of stress, sleep deprivation, or demanding mental tasks.
This is especially interesting for women. Women generally have lower creatine stores than men, and emerging research suggests they may experience cognitive benefits in addition to improvements in muscle strength and healthy aging.
As an added bonus, creatine has also been shown to support muscle mass and bone health—two other important priorities in women after 40.
3. Citicoline (CDP-Choline)
Citicoline doesn't receive nearly as much attention as some trendy brain supplements, but the science behind it is quite impressive.
Citicoline provides choline, a nutrient needed to produce acetylcholine, one of the brain's most important neurotransmitters involved in learning and memory. It also helps support the structure of brain cell membranes and may improve communication between neurons.
Several clinical studies have demonstrated improvements in attention, focus, memory, and mental processing speed, particularly in older adults experiencing age-related cognitive changes.
Unlike many supplements marketed as "brain boosters," citicoline has accumulated a fairly solid body of research supporting its use.
4. Bacopa monnieri
Bacopa monnieri is an herb that has been used for centuries in Ayurvedic medicine to support memory and learning. Modern research has shown encouraging results as well. Several clinical trials suggest Bacopa may improve memory formation, information processing, and recall after several weeks of consistent use.
One important point to remember is that Bacopa is not a quick fix. Most studies don't show noticeable improvements until it has been taken daily for approximately two to three months.
Some people experience mild digestive upset when first starting Bacopa, so beginning with a lower dose may improve tolerance.
5. Lion's Mane Mushroom
Lion's mane has become increasingly popular over the past several years—and unlike many social media trends, there is actually some science behind the excitement.
Lion's mane contains compounds that appear to stimulate the production of nerve growth factor (NGF), a protein involved in the growth, maintenance, and repair of nerve cells.
Although human studies remain relatively small, several have demonstrated improvements in memory, concentration, and cognitive function. Researchers continue to investigate whether lion's mane may also play a role in supporting long-term brain health.
While more research is certainly needed, the early evidence is encouraging.
Don't Forget the Basics
It's also worth mentioning that several vitamins and minerals—including vitamin B12, vitamin D, magnesium, and iron—can contribute to fatigue, poor concentration, and memory problems when levels become deficient. If you’re experiencing brain fog, ask your practitioner to check your levels.
Likewise, no supplement can compensate for chronic sleep deprivation, unmanaged stress, uncontrolled diabetes, untreated thyroid disease, physical inactivity, or a diet high in ultra-processed foods. Even the best brain health supplements on the planet won’t move the needle if these other factors are in play.
The Bottom Line
Your brain changes as you age—and luckily there’s a lot you can do to support it during the process. A healthy lifestyle, appropriate treatment for secondary causes, and thoughtfully chosen supplements can go a long way toward helping you stay sharp for years to come.
