Buying Guide
Potency and Dosage
When selecting a magnesium oxide supplement for sleep, start with the dosage. Products range from 250 mg to 400 mg per serving. A higher potency, such as 400 mg, may be more effective for promoting deep rest, but individual needs vary. Puregen Labs offers 400 mg per tablet, while Nature Made provides both 250 mg and extra strength 400 mg options. Consider starting with a lower dose to assess tolerance, especially if you are new to magnesium supplements.
Dosage also affects how many days a bottle lasts. A 100 count bottle at 250 mg gives a 100 day supply, while a 110 count bottle of extra strength softgels also covers over three months. This convenience can simplify your nightly routine. For more on finding the right dosage, read our article on sleep support for men over 40.
