Ingredients (3.7 grams per serving)

Glycine (3 grams per serving)

Glycine is an amino acid found mainly in foods that contain gelatin, like meat and seafood.

It acts as a mild sedative, which is why research shows that supplementation with glycine before bed reduces the time it takes to fall asleep and improves sleep quality.[9][10]

Additionally—and scientists aren’t sure why yet—but studies also show that glycine improves cognitive performance and reduces feelings of fatigue when sleep is impaired.[11]

The clinically effective dose of glycine is 3 grams.

Raw salmon

Melatonin (500 micrograms per serving)

Melatonin is a hormone that’s produced by the brain and found in foods like tomatoes, walnuts, strawberries, and olive oil.

It has powerful sedative and sleep-inducing effects, which is why research shows that supplementation with melatonin before bed . . .

  • Reduces the time it takes to fall asleep[12]
  • Can improve sleep quality for those with insomnia[13][14]
  • Reduces symptoms of jet lag[15]
  • Can improve memory function[16]

The clinically effective dose of melatonin is between 500 micrograms and 5 milligrams.

Lunar contains 500 micrograms per serving because it’s a low but effective dose that works for most people. That said, some people need more melatonin to achieve the desired results, and in that case, we recommend 3 milligrams of slow-release melatonin in addition to one serving of Lunar for optimal results.[17]


Lemon Balm (600 milligrams per serving)

Lemon balm (also known as Melissa officinalis) is an herb that has been used since ancient times to relieve anxiety and agitation and promote sleep.

It enhances the effectiveness of a sedating chemical produced by the brain known as gamma-Aminobutyric acid (GABA).

That’s why research shows that supplementation with lemon balm . . .

  • Improves sleep quality[18]
  • Reduces feelings of anxiety and stress and induces feelings of calmness[19][20]
  • Improves memory[21]
  • Reduces symptoms of anxiety-related insomnia[23]

The clinically effective dose of lemon balm is between 300 and 1,200 milligrams.

Lemon balm

RC-NOS® Rutaecarpine (100 milligrams per serving)

Rutaecarpine is a molecule found in the fruit of the Evodia rutaecarpa plant, which has long been used in Traditional Chinese Medicine to raise body temperature and reduce pain and gastrointestinal distress.

It enhances the activity of enzymes known as CYP1A1/2, and this increases the body’s ability to eliminate various substances from the body, including caffeine, some toxins, and other molecules.[24][25][26][27]

By eliminating caffeine from the body faster, rutaecarpine can help improve sleep in people who have caffeine before late-day workouts.

For instance, studies show that 400 milligrams of caffeine—a little more than the amount found in one serving of most pre-workout supplements—taken up to six hours before going to bed can reduce total sleep by more than one hour.[28]

Rutaecarpine can help mitigate this effect, allowing for both pre-workout caffeine consumption and more restful sleep.

The clinically effective dose of rutaecarpine hasn’t been established yet, but 100 milligrams is known to be effective.


No Artificial Food Dyes or Other Chemical Junk

As with artificial sweeteners, studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[29][30][31][32][33]

That’s why we use natural coloring derived from fruits and other foods, as well as natural flavoring.

No Artificial Food Dyes or Other Chemical Junk
