Nootropics are a relative newcomer to the world of supplements. Despite this, they are gaining more popularity as an increasing number of people search for new ways to improve mental performance. People also often refer to nootropics as ‘smart drugs’, as they are linked with several important functions in the mind. Unfortunately, nootropics will not instantaneously raise a user’s IQ. But manufacturers say that with repeated use, nootropics can help boost certain brain functions. Some nootropics are designed to promote the production of neurotransmitters and improve memory, attention and focus. Other nootropics are said to increase blood flow to the brain and promote long-term brain health.
