Who are sleep supplements for?
Sleep supplements can be helpful for people who:
- Have trouble falling asleep due to stress or a busy mind
- Wake up frequently during the night
- Experience occasional jet lag or schedule changes
- Want extra support during high-stress periods
- Are building a better nighttime routine but still need help winding down
That’s because the right ingredients can help you feel more relaxed before bed, fall asleep faster, and stay asleep longer.* Just remember that these supplements are supposed to work with a nighttime routine. They aren’t designed to replace core sleep habits like consistent bedtime, light exposure in the morning, and limiting late caffeine.
What to look for in a sleep supplement?
- Science-backed ingredients like the ones mentioned above.
- A form you can take consistently. Capsules, powders, and tinctures can all be effective, but the best option is the one that fits smoothly into your routine.
- Options free from unnecessary fillers, artificial colors, or synthetic flavors.
- Third-party testing.
The best sleep-promoting ingredients, based on research
There’s an array of ingredients that can promote sleep—ranging from essential minerals to herbs and other bioactives. Below are some key ones to look out for (ordered by what has the most evidence to support nightly use).
Magnesium
Magnesium
Magnesium supports relaxation across the nervous system and plays a role in stress regulation, which can affect sleep quality.* Magnesium bisglycinate is often preferred because it is well absorbed and gentle on digestion. Magnesium malate and magnesium threonate are also good options.
L-theanine
L-theanine
L-theanine is an amino acid from green tea that helps quiet mental activity without causing drowsiness. It supports a calm, focused state that can make it easier to fall asleep.*
GABA
GABA
GABA is a calming neurotransmitter that helps send the brain signals to calm down. Supplement forms like PharmaGABA® are designed for better absorption and use in the body and have been clinically shown to enhance sleep quality.*
Tart cherry extract
Tart cherry extract
Tart cherry contains naturally occurring compounds that may support melatonin production, and improve sleep duration and efficiency, particularly when taken consistently over time.*
Melatonin
Melatonin
Melatonin is a hormone that helps signal sleep to the body. It is most useful for short-term shifts in sleep timing.It works best for jet lag or schedule changes.
5-HTP
5-HTP
5-HTP helps the body produce serotonin, which can later convert into melatonin. This pathway may support both mood and sleep. It is often paired with vitamin B6 to support this conversion process more effectively.*
Ashwagandha
Ashwagandha
Ashwagandha is an herb that helps the body manage stress, which can indirectly support sleep.*
Traditional calming botanicals
Traditional calming botanicals
Ingredients like chamomile, lavender, saffron, and jujube offer gentler calming effects.*
