Take 2 capsules 30–60 minutes before bed with a small glass of water. Timing matters here more than most supplements — magnesium's cortisol-lowering and muscle-relaxing effects work synergistically with your body's natural sleep onset process. A few specific scenarios:

• If your primary goal is sleep quality — take it 45 minutes before your target bedtime, consistently at the same time each night
• If your primary goal is muscle recovery — taking it post-workout in the evening captures both the recovery and sleep benefit simultaneously
• If you train late at night — take it immediately post-workout rather than waiting, so the magnesium is available during the overnight repair window

Avoid taking with calcium supplements at the same time — they compete for absorption. Separate by at least 2 hours.

Not even close.

• Magnesium oxide — the form in most cheap supplements and many multivitamins — has roughly 4% bioavailability. That means 96% of what you take passes through unabsorbed, often causing the laxative effect people associate with magnesium.
• Magnesium glycinate binds the mineral to glycine, an amino acid that acts as a transport molecule through the intestinal wall.

The result is significantly higher tissue absorption, no GI distress, and the added benefit of glycine itself — which has independent research support for sleep quality and nervous system calming. You're getting two clinically relevant compounds in one capsule.

Probably yes.

• Modern agricultural soil depletion means even whole foods contain significantly less magnesium than they did 50 years ago.
• The RDA is 400–420mg for men and 310–320mg for women — most adults get roughly half that from diet alone.
• Chronic stress, alcohol, caffeine, and intense exercise all further deplete magnesium through urinary excretion.
• The symptoms of deficiency — poor sleep, muscle cramps, anxiety, fatigue, and headaches — are so common they're often mistaken for separate problems.

If you experience any of these regularly, magnesium deficiency is one of the first and easiest things to address.

No — and this is the key distinction between magnesium and pharmaceutical sleep aids.

• Magnesium doesn't sedate you, it removes the physiological barriers to natural sleep — elevated cortisol, muscle tension, and nervous system activation.
• The sleep you get is deeper and more restorative, but the waking process is natural.
• Most people report feeling more refreshed in the morning, not groggy, because the sleep quality improves rather than the sleep being chemically induced.

If you're currently relying on melatonin or sleep medications, magnesium addresses the underlying deficiency those products work around.
