Sleep Support Supplements

Shop sleep support supplements at Elite Supps. Good sleep starts with good habits - a consistent routine, limiting screens and caffeine late in the day, and a dark, cool room - and the right supplement can help support the wind-down. Our range brings together calming, well-studied ingredients like magnesium glycinate, ashwagandha and glycine that may help support restful sleep. Every member of our team is a certified nutritionist, so you can choose with confidence.

Do Sleep Supplements Work?

They can help, but they are a support, not a magic switch. Ingredients such as magnesium glycinate, glycine and ashwagandha have research suggesting they may support sleep quality or help you wind down, and they work best alongside good sleep habits. They are not a treatment for insomnia or a sleep disorder - if you regularly struggle to sleep, please see your GP.

Magnesium Glycinate for Sleep

Magnesium glycinate (also called magnesium bisglycinate) is the form most people choose for sleep, because it is gentle on the stomach and well absorbed. Magnesium helps the body relax muscles and calm the nervous system, and recent research suggests magnesium bisglycinate may support sleep quality in adults reporting poor sleep (2). Explore the full magnesium range to compare glycinate and other forms.

  • Ashwagandha - an adaptogenic herb that may help the body manage stress; reviews suggest it may support sleep quality, which makes it popular for stress-related restlessness (1).
  • Glycine - an amino acid; studies suggest around 3g before bed may support sleep quality and next-day freshness (3).
  • GABA - a neurotransmitter involved in the body's natural relaxation response, often included in wind-down formulas.
  • Tart cherry - a natural source of compounds that support the body's own sleep signalling, common in sleep powders.

How to Take Sleep Supplements

Most sleep supplements are taken around 30 to 60 minutes before bed, as part of a calming routine. Always follow the directions on the label, start with the recommended dose, and if you take medication or have a health condition, check with your healthcare professional or one of our certified nutritionists first.

What About Melatonin?

In Australia, melatonin is generally a prescription or pharmacist-only medicine, so it is not sold as a general retail supplement here. Our sleep range focuses on non-prescription options like magnesium, ashwagandha and glycine. If you would like to try melatonin, speak to your doctor or pharmacist.

When should I take sleep support supplements?
