How much magnesium per day

The recommended daily intake of magnesium varies depending on individual needs and specific health goals. For general supplementation, Andrew Huberman mentions that 300 to 400 milligrams of magnesium bisglycinate or magnesium threonate are often used by those looking to improve sleep quality, taken about 30 to 60 minutes before bedtime 1.

For overall health benefits, such as supporting vitamin D metabolism and DNA repair, ensuring a sufficient intake through diet is important. About 40% of the U.S. population does not get enough magnesium, which is typically found in dark leafy greens 2. It's important to tailor magnesium intake to your specific needs, so considering dietary sources or supplements based on personal health requirements is advised.
