Magnesium is an essential mineral that plays a key role in regulating sleep. While researchers don't fully understand the effect of magnesium on sleep behaviors, it may make sense to take moderate doses of a magnesium supplement throughout the day, especially if you're not getting enough from your diet. If you plan to use magnesium supplements as a sleep aid, it's recommended to take it 1 to 2 hours before going to bed. Magnesium gluconate, magnesium glycinate, and magnesium citrate are some of the most common magnesium supplements used to achieve better sleep.
However, it's important to not take more than the recommended amount as it can cause an upset stomach. Natural Calm is an example of magnesium citrate, which can make magnesium more absorbable. Melatonin will more directly affect your sleep and will likely have a stronger effect on sleep habits compared to magnesium, which mainly will only help you relax before bed. Therefore, it's important to consider adding magnesium to your sleep routine and take it as you need it - either in the morning or in the evening.
