Magnesium Glycinate

Magnesium Glycinate outperforms other magnesium forms for sleep, especially glycinate, which crosses the blood-brain barrier more effectively than magnesium oxide or citrate (often used as laxatives). Clinical studies show 200-400mg before bed improves sleep quality in insomniacs, particularly those with restless legs or muscle tension, by activating GABA receptors and reducing neural excitability. Available over the counter for $15-25, it has minimal side effects and is recommended by sleep doctors before prescription options. Data from a 2019 trial indicated 70% of participants reported better sleep within a week, making it 20% more effective than the average sleep supplement.
