Can DMAE Really Improve Memory and Mood?

DMAE (Dimethylaminoethanol) has been gaining attention for its potential benefits on cognitive health and mood regulation. As more people seek ways to enhance their mental clarity and emotional well-being, understanding how supplements like DMAE might help is crucial. This article explores whether DMAE can improve memory and mood based on existing research and anecdotal evidence.

What is DMAE?

DMAE, or Dimethylaminoethanol, is a compound structurally similar to choline but with one less methyl group. It is naturally produced in small amounts in the human brain and found in certain fatty fish such as salmon, sardines, and anchovies. Historically, DMAE was used in a prescription drug called Deaner (deanol p-acetamidobenzoate), marketed for children’s learning and behavioural problems. However, it was removed from the market in 1983 due to insufficient evidence of its efficacy. Today, DMAE is available as a dietary supplement and is also used in various skincare products.

Mechanism of Action

DMAE is believed to enhance cognitive function primarily by increasing the production of acetylcholine, a neurotransmitter crucial for many brain functions including memory and learning ¹. Acetylcholine helps nerve cells send signals, regulating functions such as REM sleep, muscle contractions, and pain responses. Additionally, DMAE may prevent the buildup of beta-amyloid, a substance linked to age-related cognitive decline and memory loss. By increasing acetylcholine production and reducing beta-amyloid accumulation, DMAE may support brain health, especially as we age ².

Potential Benefits of DMAE

Memory Enhancement

While there is limited scientific research on DMAE, some small studies and anecdotal evidence suggest it may help improve memory ³. The proposed mechanism involves the increase of acetylcholine levels in the brain, which plays a vital role in memory formation and recall. For example, some research has indicated that DMAE supplementation can lead to better cognitive performance in individuals with early-stage Alzheimer’s disease and other forms of dementia ⁴. However, more robust studies are needed to confirm these findings and establish the efficacy of DMAE for memory enhancement.

Mood Improvement

DMAE has also been studied for its potential effects on mood and emotional well-being. Some studies suggest that it can help reduce symptoms of depression, anxiety, and irritability. For instance, a study conducted in 1977 found that DMAE reduced depression and anxiety in individuals with age-related cognitive decline ⁵. Additionally, anecdotal reports indicate that DMAE supplementation can lead to improved mood, increased motivation, and a sense of well-being. The exact mechanism is not fully understood, but it may involve DMAE’s impact on brain chemistry and neurotransmitter activity.

DMAE in Skin Health

DMAE is also commonly used in skincare products due to its potential benefits for aging skin. It is believed to help reduce wrinkles, and firm sagging skin, and improve overall skin appearance. Studies have shown that topical application of DMAE can lead to significant improvements in skin firmness and hydration. For example, a clinical study reported in the American Journal of Clinical Dermatology found that a facial gel containing 3% DMAE reduced fine lines around the eyes and forehead after 16 weeks of use ⁶. These benefits are thought to result from DMAE’s ability to hydrate the skin and enhance its structural integrity.

Risks and Side Effects

While DMAE has potential benefits, it also comes with risks and side effects. Common side effects include headaches, muscle tension, and skin irritation. More severe risks involve the potential for seizures, particularly in individuals with epilepsy or bipolar disorder. Pregnant and breastfeeding women are advised to avoid DMAE due to the risk of birth defects. DMAE can also interact with certain medications, such as cholinergic and anticholinergic drugs, potentially reducing their efficacy or causing adverse reactions. It is essential to consult a healthcare provider before starting DMAE supplementation, especially if you have underlying health conditions or are taking other medications.

Dosage and Usage Guidelines

The recommended dosage for DMAE varies depending on the intended use, but it generally ranges from 100 to 500 mg per day. It is crucial to follow the dosing instructions provided by the supplement manufacturer and to start with a lower dose to assess tolerance. DMAE is best taken in the morning before or with breakfast to avoid potential insomnia. Cycling the use of DMAE, such as taking it a few days a week rather than daily, may help prevent tolerance and reduce the risk of side effects. As always, consulting with a healthcare provider is recommended to determine the appropriate dosage and usage for your specific needs.

Scientific Evidence and Research

Research on DMAE’s effects on cognitive function and mood is limited but promising. Some studies have shown positive results, such as improved cognitive performance and mood enhancement in individuals with cognitive decline. For instance, early studies in the 1960s and 1970s suggested that DMAE could reduce hyperactivity and improve attention in children ⁷. More recent research has focused on its potential to support brain health and improve skin appearance.

One study involving 80 participants found that DMAE supplementation led to decreased theta and alpha brain waves ⁸, which are associated with increased vigilance and attention. Another study reported that DMAE reduced symptoms of depression and anxiety in older adults ⁹. However, many of these studies are small and lack robust methodology, making it difficult to draw definitive conclusions. More high-quality, large-scale studies are needed to fully understand the potential benefits and mechanisms of DMAE.

Conclusion

DMAE shows potential as a supplement for improving memory and mood, supported by some studies and anecdotal evidence. However, the current research is not conclusive, and more rigorous studies are needed to confirm these benefits. DMAE also carries risks and side effects, making it essential to consult with a healthcare provider before starting supplementation. By understanding the potential benefits and risks, individuals can make informed decisions about whether DMAE is a suitable option for enhancing their cognitive health and emotional well-being.
