If you’ve found yourself forgetting names, struggling to concentrate, or feeling mentally sluggish after turning 40, you’re not alone. Hormonal changes, chronic stress, poor sleep, and the natural aging process can all contribute to brain fog and memory lapses. While a healthy diet, regular exercise, and quality sleep remain the foundation of brain health, experts say certain supplements may also help support focus, mental clarity, and cognitive performance. From adaptogenic herbs to nutrients that boost neurotransmitter activity, here are five supplements experts recommend for helping reduce brain fog and support memory.

1. Rhodiola Rosea
Neuroscientist Emily McDonald, known on TikTok as @emonthebrain highlights rhodiola rosea as her top pick, emphasizing its ability to increase dopamine, serotonin, acetylcholine, and norepinephrine. This adaptogenic herb has been used for centuries in traditional medicine to combat fatigue and enhance cognitive function, making it a popular choice for individuals seeking to alleviate brain fog. "Rhodiola increases focus, attention, mental clarity, and mood," McDonald explains.
2. Alpha GPC and Huperzine A
McDonald introduces alpha GPC and Huperzine A as two more fantastic supplements that work to reduce brain fog. "These both work to increase the activity of acetylcholine, helpful for working memory," she explains. Alpha GPC is a natural choline compound that crosses the blood-brain barrier and supports the synthesis of acetylcholine, while Huperzine A inhibits the breakdown of acetylcholine, leading to improved cognitive function and memory retention.
3. Ginkgo Biloba and Bacopa Monnieri
Next up are two adaptogens that could do wonders for your brain. McDonald recommends Ginkgo Biloba and Bacopa Monnieri for their ability to increase the activity of acetylcholine, which, as noted above, is essential for working memory. Ginkgo biloba, derived from the leaves of the ginkgo tree, has been shown to enhance blood flow to the brain and support cognitive function. Bacopa monnieri, a herb used in Ayurvedic medicine, has been associated with improved memory and cognitive performance, making it a promising option for combating brain fog.
4. Creatine
Creatine isn't just for athletes—research suggests it may also benefit the brain. While it's best known for improving strength and muscle recovery, creatine helps replenish the body's energy stores, including those used by brain cells. Some studies have found that creatine supplementation may improve short-term memory, mental fatigue, and cognitive performance, particularly during periods of sleep deprivation or intense mental work. It may be especially helpful for women over 40 who notice reduced mental energy or increased brain fog.
5. Omega-3 Fatty Acids
Omega-3 fatty acids, particularly DHA and EPA, are essential for maintaining healthy brain cells and supporting communication between neurons. As we age, getting enough omega-3s becomes increasingly important for preserving memory and cognitive function.
Research suggests omega-3 supplements may help reduce inflammation, support mood, and improve memory and executive function. If you don't regularly eat fatty fish like salmon, sardines, or mackerel, an omega-3 supplement may be worth discussing with your healthcare provider.
Before starting any new supplement, consult your healthcare provider, especially if you have underlying health conditions or take prescription medications. Supplements can interact with certain medications and may not be appropriate for everyone.
