Sleep and Stress

Supplements for sleep, stress and mood, covering both individual ingredient reviews (melatonin, valerian root, ashwagandha, magnesium glycinate) and the head-to-head guides that compare them — ashwagandha versus rhodiola for stress, glycine versus magnesium glycinate for sleep, and a broader look at supplements for stress and anxiety.

These three areas overlap more than most supplement categories: a poor night's sleep worsens next-day stress, and a stressed nervous system makes sleep harder, so several of the ingredients here (particularly the adaptogens) show up across more than one guide. Check the safety notes on each review before combining anything, especially anything with sedative or blood-pressure effects.
