Attention is a vital component of our day to day functioning.

When impacted, it can lead to significant consequences in our lives.

Is your ability to concentrate and stay focused on your job or project seemingly getting worse? You are not alone. Many people are increasingly complaining that they are finding it hard to sustain attention and keep their focus on their job, in the boardroom, during a sporting performance, completing schooling, or simply during conversations with friends and family.

Attention refers to the mental ability of an individual to focus or narrow their awareness on selected stimuli from the external environment or on internal moods, thoughts, memories, and physical sensations that are behaviourally relevant from those that are behaviourally irrelevant (Raz, 2004).

Attention is a vital component of our day to day functioning and when impacted, it can lead to significant consequences in our lives. Now more than ever, this seems to be an increasing problem with the impact Covid has had on our stress levels and sleep. Developing evidence is beginning to show the significant impacts of Covid on brain functioning, irrespective of whether you had symptoms or not, suggesting that the negative impacts may last longer than the virus itself and may even increase the risk of Alzheimer’s disease.  

Your brain may well be wired and set up to excel intellectually but if your ability to focus and pay attention is compromised, then realising that potential becomes far more challenging and likely improbable. And sadly, the more you realise your attention is failing you, the worse it gets as you stress and worry about the impact it will have on your performance and if others will notice as you increasingly make more mistakes.

Factors that Impact Attention 

Attention is commonly reported to be impacted by things like anxiety, depressed mood, fatigue, stress and is a common symptom feature in most mental health conditions including anxiety, depression, attention deficit hyperactivity disorder (ADHD), age-related cognitive decline, Alzheimer’s dementia and is also commonly found in viral infections of all sorts. Having read widely and considered a large volume of information on all these diseases and reports of poor focus/attention and memory, I have come to conclude that the main driver behind all these struggles is ‘stress’. Now understanding what I mean by ‘stress’ is important as I am not just talking about when people say, ‘I’m stressed at work’, although this is important. I am talking more about ‘oxidative stress’ that results from unrelenting ‘demand’ on the person’s physiology and resources, both from within the body and from the environment, to the point the body can no longer keep up with the build-up of by-products from cellular stress known as free radicals, which leads to inflammation and more specifically, neuro-inflammation. 

Our bodies are stressed from psychological worry and constant, unrelenting demand on our fight and flight system coming at us from all angles: work, kids, finances; news 24 hours a day of disasters, murders, accidents, Covid; ingesting chlorine in our water, poisonous sprays in our food, chemicals in our skin and hair products, and the list goes on and on. All of these ‘stress’ the body and then, to make matters worse, we sleep less than 7 hours a night and impair the natural detox process even further. All of this leads to overwhelming ‘toxic’ stress overload. 

Inflammation Has Been Linked to a Multitude of Conditions

The gut-brain connection is now well established and most readers will be familiar with leaky gut/dysbiosis and the role this plays in the inflammatory process.

Recent research has begun to discuss the role of the blood-brain barrier (BBB) in some conditions such as Alzheimer’s disease, having been found to be ‘leaky’ in much the same way as we see in the gut. It would appear that our lifestyles, the constant bombardment of stress on our lives coming from all directions is leading to the degradation of these two very important barriers, increasingly allowing what should not go through, into our body and into our brain. No wonder we are experiencing increasing levels of mental health issues, brain fog, Alzheimer’s, autism, and all forms of autoimmune disease. 

Improving Attention and Focus

The important question on everyone’s mind is, ‘Can I improve or treat these neuro-inflammatory conditions?’ And the simple answer is that you certainly can do much to significantly improve or even address many if not most. It appears from the literature in the field of ‘peak performance’, that even for those without diagnosed conditions, that attention, focus, memory and performance can be improved and provide that competitive edge that so many sports people and top executives are looking for, implementing, and seeing dramatic results. Emerging evidence in the field of Alzheimer’s is also beginning to show the possibility of delaying the onset of this awful condition. At the very least, preventing it despite possible genetic links is appearing increasingly possible.

If you are serious about improving your attention and focus, then improving your brain health is a must and the only way to achieve this goal. If you give your brain the attention and love it needs and deserves, your brain will begin to function the way it was designed to and then everything changes.

Although I am passionate about neuromodulation and the significant advances being made in the fields of neurostimulation, I will leave that for another article, and consider over a series of upcoming posts, strategies you can consider employing now to address brain inflammation. I have come to see within my own clinic that even neurotherapies (such as neurofeedback) that have proven track records for addressing ADHD don’t seem to work or last in effectiveness unless the foundational cause of most neurological issues (inflammation) is addressed.  

The key areas within my N.E.U.R.O program, that should all be worked on within a complex systems mindset, include Nutritional Supplementation and Food, Exercise (or more specifically, daily movement), Unwinding (stress management/disconnecting daily) Restorative Sleep and Optimising Brain Plasticity, with targeted brain strengthening exercises like neurofeedback, neurogames, reading, dancing or learning a new language. 

Many of my patients are seeking some immediate help and need immediate support for motivation and attention, and so targeted supplements will often be the first line of support to help underpin being able to implement all the other vital lifestyle changes.

Supplements for Brain Health and Function

Supplementing without working on all the other lifestyle changes mentioned above is going to be a waste of time and money in the long run. However, beginning here may help with motivation and temporarily give the brain a lift – enough to help with motivation to make all the vital changes for lasting success.

The risk of reviewing supplements is that the information can become overwhelming and often lead to not taking action at all. As such, at the end of this article is one recommended combination that saves you the time on having to go and research all the products that are out there – so keep reading.

It is simply not true that supplements lack evidence. Many do have extensive science and research findings to back them up and should not be dismissed so readily. They have the capacity and evidence to support boosting focus and concentration, memory and recall and can reduce and even resolve depression and anxiety and ADHD.

It is also not true that supplements are safe. Yes, certainly, they have better safety profiles than most, if not all medicines, but if not balanced and matched to address underlying drivers, supplements can make matters worse. For example, L-Tyrosine is a commonly used amino acid that the body uses to convert into dopamine. Dopamine is one of the neurotransmitters that appears to play a role in supporting the attention networks and have been found to be deficient in ADHD. However, even though supplementing with this alone can have significant impacts on attention, ongoing use can lead to a change for the negative in other neurotransmitters and end up causing other concerns with mood or sleep. This is why it is important to understand balance when supplementing. Some vitamins, like most of the B-group vitamins, are used by the body and brain and the excess excreted in your urine, but other supplements/nootropics (fancy word for supplements for brain health) can build up over time.

High doses are not necessarily the way to go. Many researchers use high doses in an attempt to elicit a response in a shorter window of time. If one is seeking to take these over a much longer period of time, then lower dosages may be better. Yes, it may take a little longer to notice the impact, but at least it may be longer-lasting. 

Avoiding tolerance is also important to consider. Ritalin, for example, appears to have an 18-month effectiveness period, with increasing dosages needed during this period to achieve the same effect as the body and brain habituates. This is seen in antidepressant medications, melatonin supplementation (when in doses higher than 1mg) and may be seen with supplements too. For this reason, cycling the supplements may be the best way to go as well as ensuring the balance in your supplement stack to help compensate for the tolerance effect.

More importantly, supplements, herbs and nootropics may interact with other medications and should never be blindly taken without proper supervision from a well trained nutritional medicine practitioner or GP.

Synergistic Use of Supplements for Brain Health

In the movie Limitless, Bradley Cooper’s character took just one pill, called NZT-48, and instantly was able to magically recall with perfection, and access vast amounts of information – making him a super processing machine. Consensus is that this is not possible and never will be, but advances in the peptide and peak performance sector is beginning to show that combinations of various supplements, peptides and lifestyle changes, tailored to the individual’s specific genetic needs can significantly improve performance on nearly all metrics. The synergistic effects of combined supplements are important (and beyond the scope of this article to explore). 

These are some of the best supplements for brain health that I have come across that work well synergistically, and seem to be of some real assistance when it comes to the brain, attention, focus and memory and have also proven useful in helping with ADHD for those wanting to avoid stimulant medication.


Pycnogenol® is a standardised exctract of the French maritime pine bark. Research began way back in 1965, with more than 370 clinical studies since conducted. It is a powerful antioxidant that promotes the delivery of blood to the brain and protects cells from oxidative stress membrane damage, DNA damage and inflammation. It also appears to prevent decreases in dopamine and norepinephrine – all shown to be an issue in conditions like ADHD and Alzheimer’s disease. Intensive clinical research has established its benefits for attention and other higher brain functions in kids as well as adults and is established as a viable treatment for ADHD hyperactivity symptoms in children.


Choline is essential in the formation of acetylcholine, a neurotransmitter that plays an important role in mental function and cell membrane function. Choline enhances focus, supports healthy memory, and promotes calm. It is present in every cell in your body. It is regarded as an essential nutrient, as your body uses it faster than it can produce it and in fact, without it, we could not move, think, sleep or function. Research from hundreds of studies has shown that supplementing with a form of choline called CDP-choline or citicoline, will boost cognition, increase brain energy and speed up formation of cell membranes, boost production of acetylcholine, increase blood flow to the brain, offset harmful effects of stroke, improve memory and learning and boost cognitive performance and memory in Alzheimer’s.


Phosphatidylserine (PS) is a universal building block for cell membranes, playing a significant role in their repair. This phospholipid nutrient is present in all our cells and is especially concentrated in the brain’s nerve cells. PS helps to improve attention and the ability to cope with stress. It is known to improve alertness, cognition, memory, recall and mood and may lower anxiety. PS is the best-documented nutrient for the recall of words, names, faces, and events in people over 50. PS starts to decline when we reach our 20s and can impact on attention, concentration, and memory as we age. We get this from organ meats which most do not eat and so including this in our supplements for brain health is vital to staving off age related brain decline and improving attention, focus and memory.


Acetyl-L-carnitine (ALC or ALCAR) is an amino acid that is naturally produced in the body and is important for energy production. It assists in the proper functioning of genes, enzymes and neurotransmitters. Among ALC’s many benefits are its promotion of healthy memory, lessening of mental fatigue, enhancement of mood, and support for the production of acetylcholine which is a major memory neurotransmitter. The acetyl form is better absorbed and thus more likely to be used by the body and brain. ALC promotes brain energy by fueling your mitochondria. There are studies showing positive effects for depression, dementia, neuronal growth, and mild cognitive impairment. Studies considering supplements for brain health also showed ALC can slow rates of cognitive decline, improve chronic fatigue syndrome, and protect the brain from oxidative damage. A meta-analysis in 2018 by Nicola Veronese et al. looked into randomised controlled trials of ALC alone or in combination with antidepressant medications with a control group taking a placebo/no intervention or antidepressants. 12 studies were included with 791 participants. They concluded that ALC supplementation significantly decreases depressive symptoms against placebo and offered a comparable effect with that of established antidepressant agents with fewer adverse effects.


Rhodiola is one of the best studied and most potent adaptogens (helping our bodies and brain adapt and respond better to stress). Rhodiola is fast-acting and has been shown to fight fatigue, support a positive mood, and improve physical and mental alertness and performance. It also helps increase the availability of energy during the day, helping to fight fatigue and promoting restful sleep. There are over 180 studies on this plant supplement which has been shown to be as effective in treating depression and anxiety as the medications commonly used. It is highly effective in protecting neurons from stress related damage (inflammation). It also appears to influence neurotransmitters like serotonin, norepinephrine and beta-endorphins. 


Tyrosine (L-tyrosine) is an amino acid that is required for the production of the neurotransmitters dopamine, epinephrine, and norepinephrine. The thyroid gland needs tyrosine to make the hormone thyroxine, and the skin needs it to make melanin. Having sufficient quantities of tyrosine in the brain promotes mental clarity in dealing with stress and enhances working memory, executive functions including focus and concentration, mood, anxiety and lessens ADHD symptoms. Studies have shown benefits, but this is not always lasting, so it is important to keep in mind that tolerance can be reached with high doses of this amino acid. One study by Hinz et al. in 2011 where 85 young people with ADHD were treated for a period of 8-10 weeks found treatment to be equal in efficacy to stimulant medications.  


Lion’s mane mushroom is an ancient Chinese remedy for improving cognitive performance. This mushroom has been found to specifically address the root cause of many issues through preventing and treating nerve damage by boosting nerve growth factor (or neurogenesis). As such, it has been shown to boost memory and cognition. This mushroom is mostly backed by animal studies, however, promising results from one pilot trial on dementia and preclinical studies have shown the brain and nerve benefits. The results have not been replicated but this strongly encourages more research to be done. There are 7 studies looking at lion’s mane mushroom in inflammation, but no clinical studies. Lion’s mane mushroom extract was shown to exhibit anti-inflammatory activity thought to be due to inhibition of nitric oxide generation, suggesting a possible role as either a preventive or therapeutic anti-inflammatory agent.


L-theanine is an amino acid green tea extract that reduces anxiety by promoting relaxation. It slows down the heartbeat, reduces blood pressure, diminishes the acuteness of stress – all the while improving focus, attention and concentration. Research has demonstrated the various effects L-theanine has on GABA, serotonin, melatonin and BDNF levels such that it has shown profound effects on neurogenesis and neuroplasticity and is able to regulate mood, motivation, cognition and memory. L-theanine helps to lower levels of the stress hormone corticosterone, and avoid the interference with memory and learning.

L-theanine research has shown it can increase attention span and reaction time in people who are prone to anxiety. It may even help improve accuracy, with one study showing that it reduced the number of errors made in a test of attention. IN Lyon, MR et al. (2011), a randsomised double-blind, controlled clinical trial showed that L-theanine (Suntheanine®) led to improvement on objective sleep quality in boys with ADHD. This is important to note with sleep playing such a significant role in ADHD. 

There are many more supplements, such as saffron, that have also shown benefit in treating ADHD and depression, equivalent to stimulant and antidepressant medication without the side effects. It is important to keep in mind that many of these are small studies. However, when it comes to nutritional medicine research, the lack of any real financial gain limits the research investment and the size of research desired may never come despite the promising initial results being observed.

In my own clinic, where non-medication based approaches are sought, I use BIOv8, which is a good combination supplement of some, if not most, of the discussed supplements. It is made within Australia, which provides more reassurance and guarantees to me that I am indeed getting the quality ingredients and thus more likely to see results. Supporting this with a high potency omega-3 supplement that seeks to provide around 1000mg of both DHA and EPA, along with a daily vitamin D supplement is a further way to address neuroinflammation and address the documented significant deficiencies of these very important compounds found within ADHD and general populations alike. It is also important to ensure that adequate multi-vitamin support is included which will provide most of the co-factors that many of the above supplements for brain health need to ensure effectiveness and to keep the whole complex system within balance.

A final note is to always ensure that you discuss your use of any supplements with a trained clinician and that you particularly seek this advice if you are taking any medications, are pregnant or breastfeeding and treat these as you would any medications – with caution.
