Based on the studies selected for the aim of the current systematic review, we may form adequate conclusions regarding the impact of select SNPs on the ergogenic and anxiogenic consequences and habitual use of caffeine in humans. This can slow the breakdown of caffeine, for example, leading to caffeine overstimulation.

Further, while caffeine is generally well tolerated, some individuals report feelings of anxiety following consumption . The two main gene mutations that cause anxiety include the C677T and the A1298C genes. For example, the selective serotonin reuptake inhibitors Prozac (fluoxetine), Paxil (paroxetine), and Luvox (fluvoxamine), commonly used to treat depression, social anxiety, and obsessive eating disorders, are inhibitors of the CYP1A2, and therefore interfere with the body’s ability to catalyze the biotransformation of caffeine.
