Non-prescription focus supplements?!

It is difficult to really say that anything does not have side effects. However, rhodiola rosea is a plant that is classified as an adaptogen. This class of herbs refers to those herbs that are believed to have an overall benefit to the body. Also known as Golden Root, rhodiola rosea increases blood flow to the brain, and users claim that it increases mental and physical performance. It has been used by Russian athletes to gain an edge. Reports on rhodiola generally seem to point toward it having limited side effects. http://worldseedsupply.org/proddetail.ph…

You may also want to look into piracetam, which has been around for a long time. Many people find it useful for what you are asking. There are many derivatives that are considered even more effective, although I am unsure about side effects. Piracetam is considered to have few side effects like rhodiola. http://www.bonanza.com/booths/sonofdad2/…
