Magnesium and Sleep: Separating Fact from Fiction
Sleep disturbances are a common concern, impacting overall health and well-being. As interest grows in natural sleep aids, magnesium has emerged as a popular option, but is its effectiveness backed by scientific evidence? Recent research is shedding light on the potential benefits of specific magnesium compounds for improving sleep quality and daytime function.
A randomized, double-blind, placebo-controlled study involving 80 adults aged 35-55 with self-reported sleep problems investigated the effects of Magnesium L-threonate (MgT). Participants took either 1 gram per day of MgT or a placebo for 21 days. The study, published in Sleep Medicine X on August 17, 2024, found that MgT supplementation improved both sleep quality and daytime functioning. Details of the study are available through the National Institutes of Health.
Researchers, including Heather A. Hausenblas of Jacksonville University and Tarah Lynch, also from Jacksonville University, along with Stephanie Hooper of the University of North Florida, Aahana Shrestha and Doug Rosendale of AIDP, and Jennifer Gu of AIDP, conducted the research.

Magnesium L-threonate is considered a promising intervention due to its ability to cross the blood-brain barrier, potentially impacting cognition, memory, and mood. This enhanced bioavailability distinguishes it from other forms of magnesium. The findings suggest a potential avenue for addressing sleep issues through targeted supplementation.
Another study, a randomized double-blind placebo-controlled crossover pilot trial, examined the effectiveness of magnesium supplementation on sleep quality and mood in adults experiencing nonclinical insomnia symptoms. This research, involving 31 adults with an average age of 46, compared 1 gram per day of Upgraded Magnesium™ to a placebo over two weeks, with a two-week washout period between conditions. The study, published on July 26, 2024, in the Medical Research Archives, showed significant improvements in sleep quality, mood, and activity levels in the magnesium group. Researchers included Michael J. Breus, PhD, Stephanie Hooper, MPH, Tarah Lynch, MS, and Heather A. Hausenblas, PhD.
Still, a systematic review of available literature published on February 19, 2022, in Biological Trace Element Research, revealed a more nuanced picture. Even as observational studies indicated an association between magnesium status and sleep quality – including factors like daytime sleepiness and sleep duration – randomized clinical trials showed uncertain results regarding magnesium supplementation and sleep disorders. The review analyzed data from 7,582 subjects across nine studies, highlighting the need for further research to clarify the role of magnesium in sleep health.
These findings underscore the importance of considering the type of magnesium used and the individual’s magnesium status when evaluating its potential benefits for sleep. While magnesium supplementation may offer improvements for some, more research is needed to establish definitive guidelines and recommendations. This research is vital as sleep problems challenge overall wellbeing and affect a large portion of the population.
