Everything starts with your brain. Difficulty concentrating can be influenced by several factors, such as inadequate sleep, stress, anxiety, mental fatigue, or what is commonly described and known as “brain fog.”
What Are Nootropics?
Nootropics are natural or synthetic substances that are marketed for their potential to support cognitive function and mental performance. Depending on where you live, many nootropics may be available over-the-counter (OTC), while others require a prescription from a healthcare professional.
Always consult with a healthcare professional regarding usage and dosage if you’re considering taking any nootropic or supplement. That said, some nootropics have preliminary evidence suggesting potential benefits for certain aspects of cognitive functioning, including
- Motivation
- Memory
- Mood
- Creativity
- Attention and focus
Today, we’ll focus on nootropics that target improved focus and concentration. There are many nootropics on the market, though the strength of evidence varies among them, and not all have been shown to directly improve concentration.
Top Three Nootropics for Concentration
We’ve boiled down all of the best nootropics for concentration into our top three choices. Each of these nootropics may offer benefits beyond improved concentration and may be able to improve other areas of brain functioning, such as enhancing memory and reducing anxiety, to prevent issues with attention span and focus in the future.
GABA (Aminalon)
GABA (also sold under the name ‘Aminalon’), or gamma-aminobutyric acid, is an inhibitory neurotransmitter (in fact, it is the brain's primary inhibitory neurotransmitter) and a compound that has been studied for its potential calming and neuroprotective effects.
Some research has observed altered GABA signaling in individuals with attention-deficit/hyperactivity disorder (ADHD). Inattentiveness, impulsivity, and hyperactivity—all associated with a lack of focus or concentration—are common symptoms for this disorder. Read our article about the differences between ADHD and BPD.
GABA is known for its role in calming the nervous system, and while it is naturally produced in humans and animals, and some studies suggest its potential effects on relaxation, stress response, and blood pressure, evidence supporting oral GABA supplementation for improving focus or cognitive performance remains limited.
While GABA is available OTC in the United States, manufacturers make different recommendations regarding dosages. We always recommend consulting with a healthcare professional before taking GABA.
MemoProve (N-Pep-12)
MemoProve may be able to boost memory, concentration, and alertness. MemoProve (N-Pep-12) is a proprietary peptide blend that has been studied for its potential effects on cognitive function. One study has suggested that MemoProve may support aspects of memory and attention in adults. In this study, subjects took MemoProve for thirty days and were then tested on various cognitive functioning tests, and the subjects who took MemoProve performed better than subjects who were given a placebo during that same time period.
Some preclinical and early human research suggests potential effects on learning-related processes, though direct evidence of enhanced neuroplasticity in humans is still somehow limited, indicating that while MemoProve shows promise, further research is needed to fully understand its impact on cognitive enhancement. For these reasons, MemoProve may be the perfect nootropic if you’re experiencing memory problems, issues with sleep, struggling with concentration, or undergoing work stress or overload. Consult a healthcare professional to see if MemoProve is right for you.
Theanine (L-Theanine)
Theanine, or L-theanine, is a natural nootropic that is an amino acid found in green tea or mushrooms. It is quickly absorbed in the small intestine, which allows it to cross the blood-brain barrier. Also, it has been studied for its potential neuroprotective and calming effects. Research suggests this can increase relaxing neurochemicals in the body while modulating neurotransmitter activity associated with stress and arousal, which may indirectly support attention and focus.
Taking theanine may increase the brain’s production of serotonin, dopamine, and GABA–which we know can also target improvement in focus and attention span. These hormones and neurotransmitters play a key role in alertness, concentration, and other bodily functions that can contribute to improved cognitive abilities.
Because L-theanine has been studied for its calming effects without causing sedation, it may be a reasonable option for individuals seeking support for focus, particularly when stress or anxiety is a contributing factor. Ask your healthcare professional if they recommend theanine as a supplement for you.
In Summary
There are many nootropics with evidence to support claims of improved focus, attention span, and cognitive function. Whether you’re a young adult experiencing occasional attention difficulties or an older adult aiming to support cognitive health, there may be a nootropic that offers the benefits you need. Consult your healthcare professional today to see if GABA, MemoProve, or theanine are right for you. Here you can find a list of top more nootropics for concentration and here 5 best nootropics for studying.
