It also assessed the effects of magnesium on selected blood markers. The main questions it aimed to answer were: Did magnesium supplementation improve sleep quality? Did magnesium supplementation improve cognitive function?

Interventions
Magnesium supplementation was administered to eligible participants using magnesium citrate tablets (Solgar®, USA), a highly bioavailable form commonly used in research. The supplements were purchased from Al Nahdi Pharmacy (Saudi Arabia) and selected based on previous studies demonstrating good absorption and effectiveness. Participants received a total daily dose of 400 mg elemental magnesium. Eligible participants were instructed to take the supplement for 90 days, divided into two doses: one in the afternoon and one 1-2 hours before bedtime. The supplement was provided in bottles containing 120 tablets. Participants were asked to maintain their usual diet and lifestyle. Compliance was monitored using participant diaries and by counting remaining capsules returned at the follow-up visit.
