claimBased on data from the sleep tracking ring, there were no group differences in sleep outcomes, although there was a greater reduction in HR ( p = 0.030) and an increase in HRV ( p = 0.036), a physiological marker of stress reduction and improved autonomic balance.

claimConclusion The results from this study suggest Magtein ® supplementation for 6 weeks improves overall cognition, cognitive age, working memory, reaction time, HR, HRV, and some subjective, but not objective measures of sleep in healthy adults with self-reported dissatisfied sleep.
