The human body is constantly bombarded by ionizing radiation, harmful chemicals, oxidants, and foreign organisms which can lead to tissue damage and brain decline with age.

Shea et al. from the University of Massachusetss in Lowell showed that their “smart-pill,” which contains brain-boosting chemicals glutathione, acetyl-L-carnitine, and S-adenosyl methionine, increases the decision-processing and thinking speeds of subjects. Patients given placebos did not show any similar increase.

This brain-boosting pill could potentially be useful for aging people to become sharper and stay sharper.
