Supplements for Brain Function and Memory
Many dietary supplements are advertised as beneficial for brain function and memory. They may also claim to improve cognitive performance.
Science is often uncertain about the efficacy of these supplements, and there are even reports that some may cause harm.
Talking to a healthcare professional before starting any new supplement regimen is always a good idea.
Some of the most commonly marketed brain function supplements include:
B vitamins
These are a group of water-soluble vitamins that are essential for many bodily functions, including brain function.
Vitamin B12, in particular, plays a crucial role in forming red blood cells and maintaining the nervous system, including the brain.
The deficiency of certain B vitamins, such as vitamin B12, may increase the risk of cognitive decline and dementia, according to some studies.
However, the evidence for the effectiveness of B vitamin supplements in improving cognitive function in healthy individuals varies.
A 2016 systematic review and meta-analysis of 10 randomized controlled trials found that B vitamin supplementation did not improve cognitive function in healthy older adults.
However, some studies have suggested that B vitamin supplementation may benefit individuals with mild cognitive impairment or those deficient in certain B vitamins.
It is important to note that B vitamin supplements can interact with certain medications and may cause side effects such as nausea, diarrhea, and skin rash in some individuals.
Ginkgo biloba
A herbal supplement known as ginkgo biloba is often touted for its cognitive and memory-boosting effects.
However, the evidence for its effectiveness could be more consistent, and it may interact with certain medications.
Ashwagandha
Traditionally, Ashwagandha is associated with promoting overall health and longevity in Ayurvedic medicine.
It sometimes appears as a dietary supplement for its potential benefits for brain function and mental health.
While there is limited research on the effects of ashwagandha, specifically on brain function and memory, some studies have suggested that it may benefit cognitive performance and anxiety levels.
For example, a 2017 study published in the Journal of Dietary Supplements found that taking ashwagandha supplements improved cognitive performance.
It also improved reaction time in healthy adults compared to a placebo.
Another study published in the Journal of Ayurveda and Integrative Medicine found that ashwagandha extracts reduced symptoms of anxiety and depression in individuals with moderate to severe anxiety.
However, there is a need for more research to fully understand the effects of ashwagandha on brain function and mental health.
DMAE (Dimethylaminoethanol)
It is not a food product but rather a chemical compound that occurs naturally in the body. It is often used as a dietary supplement.
Brains contain small amounts of DMAE, which shows antioxidant properties and promotes acetylcholine / choline production.

This neurotransmitter plays a role in learning and memory. DMAE is also a potential treatment for cognitive impairment, memory loss, and attention deficit hyperactivity disorder (ADHD).
This compound served effectively in anti-aging products and supplements for its supposed ability to improve skin firmness. It is said to also reduce the appearance of wrinkles.
However, the evidence for the effectiveness of DMAE in these areas needs to be more extensive and consistent.
There are concerns about its safety and potential side effects.
Some studies have suggested that when applied topically, DMAE may cause skin irritation or allergic reactions.
Evidence shows that it may negatively affect certain individuals’ heart and blood pressure.
What Is Choline
Choline is an essential nutrient that is important for many functions in the body.
It is a water-soluble vitamin-like substance that is similar to the B vitamins.
Choline is important for the proper functioning of the brain and nervous system. It is also necessary for many other processes in the body, including metabolism, DNA synthesis, and cell membrane function.
Choline is found in various foods, including eggs, liver, meat, fish, nuts, and vegetables.
The body can also synthesize it, but the amount produced may not meet the body’s needs, which is why it is considered an essential nutrient.
Choline has been studied for its potential benefits in improving cognitive function, reducing inflammation, and preventing liver disease.
Pregnant women need to consume adequate amounts of choline, as it plays a crucial role in fetal brain development.
Krill Oil Supplements
Krill oil is a dietary supplement derived from tiny, shrimp-like marine crustaceans called krill.
Rich in omega-3 fatty acids, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), it is considered essential for optimal health.
Potential benefits associated with krill oil supplements:
1. Omega-3 Fatty Acids
Krill oil is a potent source of omega-3 fatty acids, which play a crucial role in maintaining overall health. Omega-3s have anti-inflammatory properties, supporting heart health, brain function, and joint health.
2. Heart Health
Omega-3 fatty acids have been shown to have a positive impact on heart health.
They can help reduce triglyceride levels, lower blood pressure, decrease inflammation, and improve cholesterol profiles, reducing the risk of cardiovascular diseases.
3. Brain Health
DHA, one of the main components of krill oil, is highly concentrated in the brain. It plays a vital role in brain development and function.
Omega-3 fatty acids are believed to support cognitive function and may have a positive impact on conditions like depression, anxiety, and age-related cognitive decline.
4. Joint Health
Krill oil’s anti-inflammatory properties may benefit individuals suffering from joint conditions such as arthritis.
Omega-3s can help reduce joint stiffness, pain, and inflammation, improving overall joint health and mobility.
5. Skin Health
Omega-3 fatty acids are known to support healthy skin by reducing inflammation, maintaining skin barrier function, and promoting moisture retention.
In addition, krill oil supplements may contribute to healthier skin, reducing symptoms of conditions like eczema and psoriasis.
6. Antioxidant Properties
Krill oil contains astaxanthin, a potent antioxidant that gives it its distinctive red color.
Antioxidants help protect cells from damage caused by free radicals, which can contribute to various chronic diseases and premature aging.
7. Bioavailability
Krill oil has been suggested to have better bioavailability compared to other sources of omega-3s, such as fish oil.
The phospholipid structure of krill oil is thought to enhance the absorption of EPA and DHA, making it easier for the body to utilize these essential fatty acids.
However, while krill oil supplements offer potential benefits, individual responses can vary, and more research is needed to fully understand their effectiveness.
Additionally, always consult with a healthcare professional before starting any new dietary supplement regimen.
