According to a research team at Johns Hopkins University in Baltimore, caffeine may boost long term memory. It has long been thought caffeine has many health benefits and now it may be an enhancer for memory.

Researches notice the more caffeine the better the improvement in tests that were conducted. Using 100mg doses of caffeine to 300mg doses, they found performance improved after 200mg doses concluding at least 200mg dose were required to observe the effects of caffeine on memory. Scientists agree further studies are needed.

According to the US Food and Drug Administration, the average American consumes 300mg of caffeine a day through coffee, tea and soft drinks. It is also thought caffeinated drinks may reduce the risk of liver disease and the risk of suicide, but may disrupt sleep and may alter heart function.
