Summary
Participants are being invited to take part in a research study. Before deciding whether to take part, it is important for participants to understand why the research is being done and what it will involve. Purpose: This study will investigate whether a multi-ingredient nutritional supplement containing magnesium and melatonin can improve sleep quality in adults who experience disrupted sleep due to nighttime leg cramps. What participation involves: Participation lasts 8 weeks. Participants will be randomly assigned to take either the nutritional supplement or a placebo (inactive look-alike) every night before bed for 6 weeks. Participants will wear an Oura Ring wearable device on one finger continuously for 8 weeks throughout the study and complete short questionnaires using a smartphone app. The Oura Ring and study supplement will be sent to the participant's home address. Participants will never need to travel to a research centre; all contact with the research team will be by video call, phone, messaging, or email. How long: Total involvement will be 8 weeks, made up of a 2-week baseline period and a 6-week supplementation period. Each day, participants will complete a short app-based questionnaire (approximately 1 minute). At the end of weeks 2, 4, 6, and 8, participants will complete additional app-based questionnaires (approximately 10 minutes).
