01 / Basics

Magnesium: base for the nervous system and sleep

Magnesium is the first supplement to start with when working on sleep.

Deficiency prevents the nervous system from entering relaxation mode, leading to nighttime leg cramps, restless superficial sleep, and early awakenings. Magnesium deficiency is a chronic issue for most adults: it is rapidly depleted by stress and is scarce in modern diets. The most suitable forms for sleep are glycinate and citrate because they are well absorbed and do not cause a laxative effect.

Magnesium glycinate is a mineral bound to the amino acid glycine. Glycine itself acts as a calming neurotransmitter, making glycinate especially good before bed. Citrate is a versatile form.

02 / Sleep Hormone

Melatonin: restoring the circadian rhythm

Melatonin is not a sleeping pill. It does not force sleep; it signals the brain that it is time.

Melatonin is a sleep hormone produced by the pineal gland in darkness. Modern lifestyle constantly disrupts its production: screens in the evening, night shifts, flights, anxious thoughts. Taking melatonin 30–60 minutes before bed shifts your biorhythms and helps you fall asleep at the right time. Doses above 5 mg are usually excessive — 1–3 mg is enough for most people.

Important to understand: if you have an anxious mind that won’t switch off at night, melatonin alone will not solve the problem — combine it with L-theanine or magnesium.

L-Theanine: for those whose “mind won’t switch off”

Relaxation without drowsiness — ideal when the problem is not fatigue but anxious thoughts.

L-Theanine is an amino acid found in green tea. It raises GABA, dopamine, and serotonin levels in the brain, providing relaxation without drowsiness or sluggishness. Perfect for people whose issue is not “I physically cannot fall asleep” but “thoughts about work keep spinning, conversations replay in my head, anxiety won’t let go.” Take 30–60 minutes before bed; it can be combined with magnesium and melatonin.

Reviews on iHerb for Now Foods L-Theanine

Relaxes without drowsiness or energy crashes — calmness and clarity at the same time.

Helps manage stress, improves falling asleep, and daytime concentration is better.

At 600 mg at night I got 2 more hours of REM sleep than without it.
