Melatonin supports the body's sleep-wake cycle.

Benefits of Sleep

Sleep provides numerous health benefits, including defence against oxidative stress. Melatonin is a naturally occurring hormone and a powerful antioxidant that acts as a sleep aid by helping to regulate sleep and wake cycles.

Melatonin - the facts

What is it?

  • a hormone, produced naturally in the pineal gland
  • made from the amino acid tryptophan
  • an antioxidant which supports immune function

What does it do?

  • Melatonin plays a role in the body's natural rhythms, including the sleep cycle ( circadian rhythms)
  • Melatonin helps regulate other hormones, which in turn supports other body functions, such as the release of female hormones
    • Melatonin assists with the timing and release of female reproductive hormones. It helps determine when a woman starts to menstruate, the frequency and duration of menstrual cycles, and when a woman stops menstruating (menopause).
  • The body makes more melatonin in the evening, in response to less light, and maintains higher levels over night encouraging sleep
  • Blood levels of melatonin decrease as we age, which may explain why older and elderly people have more difficulty sleeping at night.


  • Supplementation can support your natural circadian rhythm and provide a more restful sleep.
  • If you are considering using melatonin supplements, talk to your doctor first.
