Higher performance of the brain is often associated with improved mood, memory, learning ability, verbal fluency, motivation, focus, confidence, or creativity. Nootropics are also known as cognitive enhancers which are marked by their ability to improve mental health, focus and concentration, and memory among other things. People of all age groups are seen inclined to using nootropics to boost their general well-being and daily mental performance. Even the healthy individuals, as well as people affected by diseases like Alzheimer’s, Parkinson’s and ADHD, can use these focus and concentration supplements – nootropics. Here is a list of top nootropics for focus and concentration.PhenylpiracetamPhenylpiracetam is more effective in improving memory and learning compared to other nootropic supplements, and by improving cerebral processing, it benefits cognitive function. Phenylpiracetam acts as an antidepressant, reduces the severity of epileptic seizures, reduces anxiety, and even relieves psychotic disorders. It stimulates the mind and increases learning capacity, focus and mental energy. Phenylpiracetam promotes pleasure, motivation and attention and enhances athletic performance. It also relieves the onset of retrograde amnesia and serves as an effective neuroprotectant.Phenylpiracetam has nootropic properties and the phenylpiracetam supplements can have a pronounced stimulatory effect on motor responses and improve physical performance. Though phenylpiracetam has previously been used by the athletes, it is now included in the WADA list of prohibited during sports.[3]Bacopa monnieriBacopa supplementation can reduce anxiety and improve memory formation. Being an adaptogen, after supplementation of Bacopa monnieri, a person feel relaxed and free from anxiety.[4]Bacopa Monnieri is one of the most commonly used natural nootropics with proven effects for boosting memory, cognitive ability and brain health. For its having wonderful brain health properties, this plant-derived natural medicine has been widely prescribed to both children and adults to enhance brain power for centuries in India. It improves cognitive performance; it is very effective for the treatment of Alzheimer’s disease and epilepsy, reduces anxiety and depression, fights stress, and helps in the treatment of attention deficit-hyperactivity disorder (ADHD) symptoms. Bacopa Monnieri improves learning and memory, and increases creativity and focus.[5]AniracetamAniracetam was developed as a more powerful analog of the nootropic drug Piracetam and is said to be 3-6 times more effective than Piracetam and has greater oral bio-availability, in part because of the fact that it is fat soluble. Aniracetam has also been used in the treatment of cognitive disturbances, mood and motor performance in patients with stroke and Alzheimer’s disease.[6]Aniracetam has immense health benefits which have made this supplement different from others. Aniracetam improves mental performance, increases memory, concentration, mental endurance, focus, memorization, and visual perception. It enhances learning capacity, creativity, and verbal fluidity. It also reduces anxiety, stress, depression, promotes mood, motivation, sleep and wakefulness. Aniracetam helps in the treatment of ADHD, autism, negative symptoms of schizophrenia.[7][8]Fladrafinil / Modafinil/ AdrafinilFladrafinil, Adrafinil and Modafinil are eugeroics, mostly known as wakefulness-promoting drugs. Fladrafinil has similar cognitive effects to those listed for both Adrafinil and Modafinil. The cognitive effects include improved memory and recall speed as well as a possible increase in learning capacity. As the attention period is also expanded, you will have the ability to concentrate and focus. You will also find it easier to engage in common tasks like reading, writing, talking, and giving presentation.Students use these supplements as study pills, for alertness and staying awake for all-night cram sessions before an important exam. These supplements reduce fatigue and diminish symptoms of ADHD in children. They also increase wakefulness and improve focus and mood, and also increase dopamine.L-theanineL-theanine is an amino acid (a building block for proteins) found ingreen tea. This natural nootropic has been researched for its ability to support brain health and enhance focus.[9]People use L-theanine for the relief of anxiety and high blood pressure, for preventing Alzheimer’s disease, and for making cancer drugs more effectively.[10] L-theanine has a lot of different benefits for mood, cognitive function and general health. L-theanine enhances the production of GABA, an amino acid and neurotransmitter, which works to calm the mind and relax the body by preventing over-excited stress signals in the brain.NoopeptNoopept is a peptide-derived compound closelyassociated with the nootropics inside the racetam  Though Noopept is an identical way of action to racetams, it is thought to probably be one thousand times stronger than Piracetam. Noopept affects NMDA and AMPA receptors in the brain. It also increases serotonin, acetylcholine, and dopamine. Dopamine plays a crucial role in motivation as well as reward. Noopept improves motivation, enhances focus and concentration, and improves overall cognitive performance.[14] You will have superior memory and superior mood.CentrophenoxineCentrophenoxine, also known by its brand name as Lucidril, is a cholinergic compound with a DMAE (Dimethylaminoethanol) component, and acts as a better absorbed transporter of DMAE into the brain. Centrophenoxine enhances brain health and functions in several ways. It helps improve memory [11] and it is done in part by increasing the enzyme acetylcholinesterase in the brain.[12] This enzyme is needed for breaking down acetylcholine once it does its function in the post-synaptic neuron. Later the choline is liberated to be taken up by the pre-synaptic neuron where acetylcholine is once again synthesized with the help of Acetyl-CoA and choline acetyltransferase.In a study, researchers compared Centrophenoxine with DMAE and determined that DMAE was about half as potent as Centrophenoxine in boosting choline and ACh levels.[13] Increased acetylcholine activity helps short-term memory, focus, concentration, and learning.
