Can I take advanced sleep when pregnant or breastfeeding?No. Advanced Sleep is not recommended during pregnancy or breastfeeding. This formula contains adaptogens, amino acids and botanical extracts that are not routinely advised during pregnancy or lactation.

If you are pregnant, planning to become pregnant, or breastfeeding, you should choose a supplement specifically formulated for pregnancy or breastfeeding and always consult a qualified healthcare professional before taking any new supplement.

Can I take it with other supplements?

What are the benefits of sleep supplements?
Sleep supplements are designed to support the body’s natural sleep processes, helping improve both how quickly you fall asleep and the quality of rest you get overnight. They are especially helpful for people experiencing occasional sleep issues related to stress, busy schedules, or difficulty unwinding at night.

Common benefits of sleep supplements include:

  • Helping you fall asleep more easily: Sleep supplements often support relaxation and calm the nervous system, making it easier to transition into sleep naturally.
  • Supporting deeper, more restorative sleep: Certain nutrients and amino acids help promote more refreshing sleep cycles, so you wake up feeling rested rather than groggy.
  • Reducing nighttime restlessness: Sleep supplements may help support longer, uninterrupted periods of sleep.

  • Promoting relaxation and stress balance: Many formulas include ingredients that help ease mental and physical tension before bedtime.
  • Supporting natural sleep-wake rhythms: Some ingredients help maintain healthy melatonin and serotonin pathways, which regulate your internal body clock.
  • Non-habit-forming sleep support: Quality sleep supplements are designed to work with the body rather than override it, making them suitable for regular use when taken as directed.
  • Improving daytime energy and focus: Better sleep quality can contribute to improved mood, concentration, and overall wellbeing during the day.

Sleep supplements work best when used alongside healthy sleep habits, such as maintaining a consistent bedtime, reducing screen exposure in the evening, and creating a calming nighttime routine.

Supporting research Plus

The research below looks at individual ingredients in Advanced Sleep, at or close to the amounts we use. It was not carried out on the finished formula.

Ashwagandha (600mg KSM-66® per serving)

Ashwagandha and sleep: a systematic review and meta-analysis (2021)

Five placebo-controlled trials, 400 adults. Ashwagandha gave a small but significant improvement in overall sleep. Effects were larger at 600mg a day or more, over 8 weeks or more, and in people with insomnia. People also felt more alert on waking.

Ashwagandha in people with insomnia and anxiety (2019)

60 adults, 300mg twice a day (600mg daily) for 10 weeks. Compared with placebo, people fell asleep faster and spent more of their time in bed asleep, measured with a wrist sleep tracker. Sleep quality and anxiety scores also improved.

Ashwagandha in healthy adults and people with insomnia (2021)

80 adults over 8 weeks. Ashwagandha improved time to fall asleep, total sleep time, sleep efficiency and time awake during the night. Benefits were larger in people with insomnia.

Ashwagandha, recovery and sleep in female footballers (2025)

30 professional players, 600mg a day for 28 days. Compared with placebo, players reported better recovery at 28 days and better sleep quality from 14 days. A small study using self-reported measures.

Magnesium (200mg from magnesium bisglycinate)

Magnesium bisglycinate in adults with poor sleep (2025)

155 adults, 250mg magnesium as bisglycinate daily for 4 weeks. Insomnia scores improved more than with placebo. The effect was modest, and larger in people who ate less magnesium to begin with.

L-Ornithine (400mg)

L-ornithine, stress and sleep quality in working adults (2014)

52 adults with mild stress and fatigue, 400mg a day for 8 weeks. Compared with placebo, cortisol was lower and people reported better sleep quality and less anger.
