Latest review conclusion

The effects of phosphatidylserine on overall symptoms of ADHD (ES 0.76; 95% CI: -0.07 to 1.60; p = 0.07) and hyperactivity-impulsivity (ES 0.24; 95% CI: -0.04 to 0.53; p = 0.09) were not statistically significant. Conclusions: Preliminary evidence suggests that phosphatidylserine may be effective for reducing symptoms of inattention in children with ADHD, although the quality of the evidence is low and additional research in this area is warranted.
