Introduction

Did you know?

• 1 in 25 adults have difficulty maintaining attention and focus.¹
• Nearly half of individuals feel their attention span isn't what it used to be.²

Attention and cognitive performance are fundamental to daily functioning, influencing productivity, learning and decision-making. Unfortunately, focus-related difficulties are increasingly prevalent, affecting individuals across all age groups leading to an upward trend in adults seeking support to improve their focus and concentration. The growing prevalence of digital distractions, stress and inadequate nutrition exacerbates attention-related challenges.

This blog highlights the role of the cholinergic system and acetylcholine optimization in enhancing cognitive performance and sustaining mental clarity through integrative strategies, including nutrition, lifestyle factors and targeted nutrient support. 

Acetylcholine and the Cholinergic System

The cholinergic system is a complex system involved in various peripheral and central nervous functions. Its most significant roles include:^3,4

1)    The transmission of signals across nerve cells for muscle activation, memory, learning, neuronal signaling, synaptic plasticity and sensory processing. 

2)    The synthesis and release of the neurotransmitter acetylcholine (ACh).

Acetylcholine is a primary neurotransmitter that, as the name implies, is synthesized from acetyl-coenzyme A (acetyl CoA) and choline. This neurotransmitter is essential for memory formation, learning and sustained attention. It acts at both nicotinic and muscarinic receptors throughout the brain, particularly in the prefrontal cortex and hippocampus, which are critical for executive function and memory recall.⁴  ACh is broken down into acetate and choline. Choline can then be recycled for use by nerves or can be converted back to phosphatidylcholine, a major component of cellular membranes.^3,4   

Studies show that individuals with higher acetylcholine activity demonstrate superior cognitive flexibility, faster reaction times and enhanced working memory. ^5–7 Conversely, acetylcholine depletion is associated with reduced attention span, slower cognitive processing and impaired recall ability.⁸

Nutrition and Lifestyle Interventions for Acetylcholine Optimization

Several factors can influence acetylcholine levels, including poor dietary intake of choline, lack of physical activity and chronic stress. Given acetylcholine's role in cognitive performance, strategic interventions aimed at preserving and enhancing cholinergic function should be a focus of clinical care.

Consuming foods high in choline is crucial since this nutrient is needed to synthesize acetylcholine. 

Key dietary sources include:

• Egg yolks (one of the highest sources of dietary choline)
• Beef and chicken liver
• Fish (rich in both choline and omega-3s)
• Soybeans and legumes
• Wheat germ and bran
• Vegetables (though smaller amounts compared to animal sources) 

Additionally, a Mediterranean-style diet, abundant in healthy fats, polyphenols, and antioxidant-rich foods, has been linked to improved cognitive performance, memory and executive function.⁹

Regular aerobic and strength exercise supports acetylcholine production by:

1. Increasing brain-derived neurotrophic factor (BDNF), which is directly involved in acetylcholine release and synapse maintenance.¹⁰
2. Increasing the release of nitric oxide (NO), which works synergistically with acetylcholine to enhance vasodilation.¹¹

Clinical Pearl: In older adults, low choline intake is associated with reduced gains in strength and muscle quality during resistance training, suggesting that adequate choline is important for muscle function and possibly acetylcholine-related neuromuscular activities.¹²

Mind-body practices can help promote increased focus, attention and cognitive performance; however, there isn't evidence to suggest a direct impact on acetylcholine production. 

1. Controlled breathing exercises, such as pranayama or diaphragmatic breathing, may help regulate cholinergic signaling, vagal tone and enhance parasympathetic nervous system activity, supporting cognitive clarity.¹³
2. Mindfulness meditation has been shown to enhance attention processing and emotional regulation through improved brain connectivity and neuroplasticity.^14,15
3. Time in nature ("green therapy") may support acetylcholine balance by reducing stress hormones.¹⁶

Clinical Pearl: Engage in physical activity in nature for an extra win!

In the digital age, one of the most pervasive disruptors of focus and cognitive efficiency is the constant influx of notifications, multitasking and screen time. Research indicates that frequent digital interruptions can lead to attention fragmentation, reducing the brain's ability to engage in sustained, deep work.¹⁷

To mitigate these effects, healthcare professionals can recommend structured digital detox strategies, such as: 

• Establishing technology-free blocks during the day
• Turning off notifications
• Using "do not disturb" settings during cognitively demanding tasks
• Implementing screen-free morning and evening routines
• Encouraging periods of boredom, creative play and real-world sensory engagement, such as connecting with others in real life, walking in nature or journaling. 

Nutrient Solutions to Optimize Acetylcholine

Targeted nutrient supplementation offers an evidence-based approach to supporting acetylcholine levels and cognitive function. 

Choline is a direct precursor to acetylcholine, which is involved in attention and cognitive performance. Supplemental and dietary intake is associated with healthy memory, attention and learning. Not all forms of choline may provide the same benefits.^18‡ Research suggests GPC and CDP-choline (citicoline) are bioavailable forms that efficiently cross the blood-brain barrier and support acetylcholine synthesis.¹⁸ Cognizin^®, a patented citicoline, increases choline and phospholipid composition in the brain.¹⁹ Studies in children, middle-aged adults and elderly adults indicate that it supports healthy cognition across a wide age range. In two studies, one involving adolescent boys and another involving middle-aged women, 250-500 mg Cognizin citicoline offered statistically significant support for daily mental task performance.^20,21

Acetyl-L-Carnitine (ALC) is an ester of the trimethylated amino acid L-carnitine. It plays a dual role in supporting cognitive function: it facilitates acetyl-CoA uptake to enhance acetylcholine production and supports mitochondrial energy production in neurons. Clinical trials suggest that ALC supplementation promotes mental clarity, reduces brain fog and supports focus in individuals with cognitive fatigue.²²

American Ginseng (Panax quinquefolius) has been shown to modulate acetylcholine release and thereby promote learning and working memory.²³ Its active components, known as ginsenosides, also possess protective properties that prevent oxidative stress-induced changes to cholinergic signaling.²⁴

Phosphatidylcholine: choline is a precursor to phosphatidylcholine, a key phospholipid found in cell membranes and serves as a reservoir for choline needed for acetylcholine synthesis.²⁵ 

Phosphatidylserine is a phospholipid critical for synaptic function and neuronal membrane integrity. Multiple studies indicate that supplementation helps support mental acuity, behavioral and cognitive parameters.^26–28

Omega-3 Fatty Acids: The long-chain omega-3 fatty acids EPA and DHA promote healthy cognition, support the release of neurotransmitters and help protect against oxidative stress. One systematic review concluded that omega-3 fatty acid intake (1-2 grams daily) promoted  cognitive performance.²⁹

Introduction

Mental health concerns are a growing global issue, with recent data indicating that nearly 1 in 8 individuals worldwide experience some form of emotional distress, including anxious feelings and mood fluctuations.¹ Evidence suggests that disruptions in gut microbiota composition, often influenced by modern diets, stress and environmental exposures, may play a role in these rising mental health concerns.²

By leveraging dietary strategies, stress management techniques and targeted nutrient support, clinicians can provide natural, sustainable solutions that optimize the microbiota-gut-brain axis to address mental health and emotional resilience.

This blog explores the underlying mechanisms of the microbiota-gut-brain axis, its role in mood regulation and evidence-based strategies, including dietary interventions, stress management techniques and targeted nutrients such as probiotics, prebiotics, ashwagandha and L-theanine to support a balanced and resilient gut-brain connection.^‡

What is the Microbiota-Gut-Brain Axis?

The microbiota-gut-brain axis is a bidirectional communication network between the gut microbiome, the central nervous system (CNS), autonomic nervous system (ANS), enteric nervous system (ENS) and the hypothalamus-pituitary-adrenal (HPA) axis.^3,4 This intricate system regulates cognitive function, mood and overall mental well-being. The gut microbiome, composed of trillions of microorganisms, influences neurotransmitter production, immune modulation and hormonal balance, all affecting neurological function and mental & emotional health.⁴

The Microbiota's Influence on the Gut-Brain Axis

The microbiota-gut-brain axis functions through several key pathways facilitating communication between the gut microbiota and the brain. These include neural, immune and endocrine pathways, each playing a distinct role in supporting mental health.

Neural Pathway

The vagus nerve is a primary conduit between the gut and brain, transmitting signals directly from the gut microbiota to the central nervous system.³ Sometimes called the “sixth sense,” the vagus nerve can sense the microbiota and transfer the information to the nervous system, where it integrates and responds appropriately.⁵ Additionally, the enteric nervous system, often called the "second brain," contains millions of neurons that interact with gut microbes to regulate neurotransmitter production and brain activity.

Immune Pathway

The gut microbiome plays a critical role in immune system regulation, influencing cytokine regulation.³ Beneficial microbes promote the release of anti-inflammatory cytokines, such as interleukin-10 (IL-10). Non-beneficial microorganisms can trigger the production of cytokines, including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), which have been implicated in neuro-immune responses and mood disturbances.⁶

Endocrine Pathway

The endocrine pathway is more commonly referred to as the neuroendocrine system. The gut microbiota modulates gut hormones and neurotransmitters made in the gut and activates the hypothalamus-pituitary-adrenal (HPA) axis. The HPA axis governs the body's stress response and is involved in mood and immune function.³ Gut bacteria produce neurotransmitters such as serotonin, dopamine and GABA, which are essential for maintaining emotional stability.⁷

The Microbiota-Gut-Brain Axis and Mood

Studies suggest that gut microbiota imbalances are linked to mood fluctuations through altered neurotransmitter production, increased intestinal permeability, HPA dysregulation and heightened cytokine production. Specific bacterial strains, such as Bifidobacterium longum and Lactobacillus helveticus, have been shown to exert anxiolytic and mood-stabilizing effects by modulating gamma-aminobutyric acid (GABA), serotonin, dopamine, tryptophan, cortisol and cytokines.⁷

Nutrition and Lifestyle Interventions to Support the Microbiota-Gut-Brain Axis

Optimizing gut health through targeted nutrition and lifestyle interventions can strengthen the microbiota-gut-brain axis and improve mood regulation.

Diet and Its Influence on the Microbiome

Diet is described as one of the most influential and rapid contributors to microbial changes.^3,4 A symbiotic relationship between fiber, polyphenols, prebiotics and fermented foods in the diet supports microbial diversity and enhances gut-brain communication.

• Fiber is a food source for beneficial bacteria and promotes short-chain fatty acid (SCFA) production. Among its benefits, SCFAs support the GI barrier, promote the production of serotonin and GABA, modulate the immune system and influence the gut-brain connection through the vagus nerve.⁸ Fruits, vegetables, legumes and whole grains are rich sources of dietary fiber.
• Polyphenol-rich foods like berries, apples, green tea, olive oil and dark chocolate may act as prebiotics.³ They have been shown to modulate the gut microbiome by increasing beneficial bacteria (i.e., Bifidobacterium, Firmicutes, Lactobacillus) and reducing harmful bacteria (i.e., Clostridium) while also supporting the body’s natural inflammatory processes and providing antioxidant and neuroprotective properties.⁹ Many polyphenol-rich foods are also a good source of fiber.
• Prebiotics found in foods like garlic, onions, leeks, bananas, apples, honey, chicory root, flaxseed and asparagus fuel the growth of beneficial bacteria. By default, many prebiotic foods are also a source of fiber and polyphenols.
• Fermented foods, including yogurt, kefir, kimchi, miso, cheese, vinegar and sauerkraut, provide beneficial probiotics that enhance gut microbiota composition and are a readily available source of SCFAs. Homemade fermented foods will provide the most probiotic diversity, and the fermentation process increases the polyphenol bioavailability.¹⁰

In contrast, a diet high in processed foods, refined sugars and artificial additives can disrupt the gut microbiome, contributing to mood fluctuations and an altered cytokine response.⁴

Stress, Physical Activity and Sleep: Their Influence on the Microbiome

Stress negatively impacts gut microbiota composition and vagal tone, increasing intestinal permeability and cytokine response.⁵ Conversely, gut microbiota diversity may influence how one handles stress, partially due to the influence on the production of GABA and serotonin.¹¹ Stress management techniques like meditation, deep breathing and cognitive behavior therapy can help restore microbial balance, reduce HPA overactivity and support emotional resilience.⁵

Physical activity, particularly aerobic exercise, fosters microbial diversity and enhances the production of beneficial short-chain fatty acids (SCFAs), improving HPA axis control and positive moods.¹²

Sleep and the microbiome have a complementary relationship. Sleep is essential for maintaining a healthy microbiome, and a diverse microbiome has been positively correlated with increased sleep efficiency and total sleep time. Sleep deprivation has been linked to shifts in microbial composition and increased cortisol levels.¹³

Nutrient Solutions to Support the Microbiota-Gut-Brain Axis

Targeted supplementation with specific nutrients and bioactive compounds can further enhance the gut-brain connection and promote positive mental health.^‡

Probiotics & Prebiotics

Probiotic supplementation has been extensively studied for its effects on gut health and mood regulation. More specifically, in 2013, the term 'psychobiotics' was coined, describing the beneficial bacteria that produce health benefits for mental health.⁷ Multiple probiotic strains have been shown to enhance GABA and serotonin receptor expression in the brain, reduce cortisol levels and reduce cytokine activation. (Table 1)^‡

The most extensive and compelling evidence to support emotional and mental health exists for Lactobacillus helveticus Rosell-52 (RO052) and Bifidobacterium longum Rosell-175 (RO175).⁷ In a randomized, double-blind, placebo-controlled trial, supplementation with this combination maintained healthy urinary cortisol levels, indicating the potential to lessen occasional stress.¹⁴ In a separate analysis, supplemented subjects reported positive mood, relaxation and enhanced cognitive function.¹⁵ Further, multiple human studies have reported positive mood effects with this specific combination of probiotic strains.⁷

Prebiotics works synergistically with probiotics. The various types of prebiotics include fructans, galactooligosaccharides, xylo-oligosaccharides, chitooligosaccharides, lactulose, resistant starch and polyphenols. Prebiotics modulate and support the growth of the gut microbiota, specifically Bifidobacteria and Lactobacilli, increase SFCA production, improve gut barrier function, modulate the immune system and positively influence mood.^16‡

Butyrate

Butyrate is one of the three most abundant short chain fatty acids (SCFAs) produced by anaerobic bacterial fermentation of polysaccharides/fiber in the colon, where it serves as an energy source for epithelial cells.¹⁷ Considered a functionally versatile molecule, butyrate provides support for maintaining gastrointestinal health and regulating the neuro-endocrine-immune pathways, in part due to its ability to cross the blood-brain barrier.^17,18‡

Ashwagandha

Ashwagandha (Withania somnifera) is an adaptogenic herb that modulates the HPA axis and maintains healthy cortisol levels. In a double-blind trial, 60 participants with high perceived stress scores were randomized to receive KSM-66 Ashwagandha^® extract (125 mg or 300 mg) or placebo twice daily for 8 weeks. A significant reduction in perceived stress scale (PSS) scores was observed with both doses of ashwagandha compared to the placebo group. Mean cortisol response decreased by 17% and 33% in the groups receiving 125 mg and 300 mg twice daily, respectively, after 8 weeks. Subjects receiving ashwagandha also exhibited significant improvements in sleep quality.^19‡

L-Theanine

L-theanine an amino acid found in green tea, may be most recognized for its ability to exert anxiolytic effects by modulating GABA activity and for its role in regulating the stress response. In a double-blind crossover trial, 30 healthy adults received l-theanine (200 mg Suntheanine^®/day) or placebo for 4 weeks. L-theanine significantly improved stress-related symptoms, including low-mood symptoms and occasional anxiety per validated questionnaires and sleep (Pittsburgh Sleep Quality Index; PSQI)^‡

Newer research also suggests that l-theanine influences the gut-brain connection by increasing beneficial bacteria, such as Lactobacillus, while also decreasing non-beneficial bacteria, such as Closterium.²¹

The Role of Neurotransmitters in Attention, Focus and Behavior

Key Points:

1. Approximately 6.76% of adults experience focus and attention related challenges.
2. Neurotransmitters such as dopamine, norepinephrine, serotonin and acetylcholine play crucial roles in managing focus-related tasks.
3. A balanced diet, regular exercise, and supplements can support neurotransmitter production and function. Consider food or supplements high in omega-3 fatty acids, vitamin D, magnesium and B vitamins for foundational support.^‡
4. Targeted supplements can support specific neurotransmitters that contribute to focus and attention: CogniPhos (acetylcholine), CurcumaSorb Mind (dopamine and serotonin) and DopaPlus (dopamine and norepinephrine).^‡

Introduction

For many, maintaining focus is a daily struggle that affects productivity and overall well-being. The prevalence of focus and attention issues is approximately 6.76%, or around roughly 366.33 million, adults globally.

What causes these challenges with focus? One crucial factor is the brain’s neurotransmitters. Focus involves the ability to sustain attention on a particular task or goal, while ignoring distractions. It is essential for effective work, learning and daily functioning. Maintaining focus can be difficult for many people, leading to decreased productivity and increased stress. In this blog, we’ll explore how neurotransmitters impact our ability to focus, the role they play in managing focus-related tasks and provide some lifestyle solutions to support focus.

Key Neurotransmitters Involved in Focus

Dopamine: is essential for motivation, attention and reward processing. It helps regulate how we perceive and respond to stimuli, influencing our ability to stay focused on tasks. Low levels of dopamine can impair our ability to concentrate, stay organized, manage time effectively and may lead to challenges in maintaining attention on tasks.¹

Norepinephrine: affects alertness and arousal. It helps the brain stay alert and responsive to stimuli, which is essential for maintaining focus. Norepinephrine has been shown to alter network activity in attention and working memory through arousal activation of the frontoparietal network, which is critical for sustained attention and alertness.²

Serotonin: influences mood, impulse control and overall cognitive function. It plays a role in managing emotional responses and maintaining a steady focus. Changes in serotonin levels can affect our emotional stability and our ability to maintain focus, leading to increased distractibility and impulsive actions.³

Acetylcholine: governs memory, learning, motivation and attention. Synthesized from choline, acetylcholine is the chief neurotransmitter of the parasympathetic nervous system and has a significant impact on muscle function, sleep, cognitive processes and mental performance.⁴ Fluctuations of acetylcholine can affect short-term memory, processing speed and word recall and can lead to learning difficulties and symptoms like brain fog.

Natural Ways to Support Neurotransmitter Balance^‡

By understanding how neurotransmitters play a role in focus, attention and mood, you can better provide guidance on lifestyle changes that support neurotransmitter balance.

Diet and Nutrition

A balanced diet rich in essential nutrients can support neurotransmitter production and function. Foods high in omega-3 fatty acids and certain nutrients, such as vitamin D, magnesium and zinc, support the synthesis of neurotransmitters or assist their functioning.⁵

Very few research studies have investigated specific dietary patterns on focus or attention outcomes in randomized clinical trials. However, there is available evidence to provide broad recommendations, such as consuming nutrient-dense foods and limiting excessive added sugars as beneficial for attention problems.

Mediterranean diets, rich in omega-3s and plant-based foods compared to Western diets, have also been associated with better mental health and mood.⁶

Exercise

Regular physical activity has been shown to boost levels of dopamine, norepinephrine and serotonin, which can enhance mood and improve concentration. In fact, in children who have problems with attention, exercise interventions improved overall executive function when participating in exercise.⁷

Additionally, there is a robust body of scientific evidence demonstrating positive outcomes on brain function in adults from long-term exercise. Several studies have shown positive effects of exercise on cognitive functioning, specifically on prefrontal cortex-dependent cognition. Even acute, short bursts of exercise have been shown to improve mood and emotional status.⁸

Supplements

• CogniPhos: A blend of clinically researched Cognizen^® citicoline, acetyl-L-carnitine, Sharp-PS^® phosphatidylserine and cofactors. Cognizen^® promotes daily cognitive performance and mental sharpness. ^9,10‡
• CurcumaSorb Mind: A curcumin and polyphenol blend to promote mood, memory and mental sharpness and support healthy levels of serotonin and dopamine. ^11‡
• DopaPlus: This formula provides the dopamine precursors L-tyrosine and L-DOPA (from Mucuna pruriens). DopaPlus supports dopamine production and maintains healthy reuptake for daily mental function and sharpness. ^{12, 13‡}
• Vitamin D + Magnesium: Vitamin D and Magnesium are both nutrients that play a role in the body’s nervous system. In a randomized-clinical trial, children supplemented with vitamin D and magnesium had a positive impact on and total difficulties compared to placebo after 8-weeks of supplementation.^14‡
• Fish oils:  are rich in omega-3 essential fatty acid. DHA, a fatty-acid in fish oil, is well recognized for its ability to support neural and cognitive function.  Epidemiological studies indicate that intake of DHA is associated with healthy cognitive function.^15‡
• Vitamin B₆: A coenzyme involved in the synthesis of neurotransmitters needed for synaptic transmission (e.g., dopamine, serotonin, GABA).^‡
• Pycnogenol®: A highly researched maritime pine bark extract, which contains a unique mixture of proanthocyanidins and other polyphenols. Clinical trials have shown that pycnogenol supports parameters related to attention in both children and adults. ^17-19‡

Conclusion

Understanding the relationship between neurotransmitters and focus offers valuable insights into managing focus-related challenges. By addressing neurotransmitter imbalances through lifestyle changes and supporting supplements, individuals can help improve their ability to concentrate and enhance their overall focus and attention.
