Nootropics, often also called smart drugs, are natural and synthetic substances that help nourish the brain and thereby improve cognitive function. They can be available as prescription drugs and dietary supplements, but in smaller quantities, they can also be contained in food. The main functional mechanism of most nootropics is the dilation of cerebral vessels, which helps blood flow and oxygenation to the brain. It originally began clinical research as a possible drug to suppress the symptoms of Parkinson's and Alzheimer's disease. Today, however, they are common among university students. Prescription drugs and medicines Most prescription nootropic drugs are stimulants and are prescribed to alleviate the symptoms of attention deficit disorders (ADHD) or Alzheimer's and Parkinson's diseases. However, these drugs are often abused by healthy individuals in an attempt to achieve a kind of mental doping. But studies confirm that the positive effects of similar drugs in healthy individuals are not demonstrable and warn of possible side effects. The individuals who do not have any health issues and whose brain functions "normally" is at a certain limit. These drugs only help to stimulate function where it is limited in some way.
Nootropics are also a common part of the daily diet for many of us. Natural nootropics include caffeine, or L-theanine, which is found in green tea. Caffeine in the form of energy drinks, tea, coffee, and more – is the most widely used nootropic worldwide. Caffeine intercepts the adenosine receptors in the brain that cause the feeling of fatigue. But it also has side effects - excessive consumption can cause tremors, anxiety, or insomnia. Combining L-theanine with caffeine can help you better manage these unwanted side effects. The best combination of these two substances is green tea, which contains both L-theanine and caffeine. Nevertheless, you can accomplish a similar effect by combining caffeine with CBD. Ginkgo biloba is a plant that helps increase blood flow to the brain. Most of the research on ginkgo biloba is related to the treatment of Alzheimer's disease. For example, a 2020 examination of twenty-eight studies showed that taking 240mg of ginkgo biloba daily positively affected cognitive function - including reaction time and memory (in adults suffering from neurodegenerative diseases).
Caution is required with nootropic products that are sold as dietary supplements. Dietary supplements are not as regulated as drugs and need not be approved by the state institute for drug control. Although many reviews are positive, there are no studies of their long-term effect on the human body. If you are considering buying them, focus on the composition of the product and look for proven brands. When you start experiencing any side effects, it is better to stop. Nootropics have the greatest benefit and future in the treatment of neurodegenerative diseases. If you are a healthy person and just want to boost your cognitive function, remember that drastic changes are unlikely to occur. It is always recommended and best to consult your doctor before taking any such dietary supplements.
