Legion Lunar Ingredients (3.5 grams per serving)

Glycine (3,000 milligrams 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 . . .

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

Lunar contains 500 micrograms per serving because, for many people, more isn’t necessary to achieve the desired results. That said, individual response does vary, and if you need more melatonin to improve your sleep, we recommend 3 milligrams of melatonin with one serving of Lunar for optimal results.[20]

Melatonin

L-Theanine (400 milligrams per serving)

L-theanine is an amino acid found primarily in tea that helps balance the levels of two chemicals in the brain known as glutamate and GABA, which transmit nerve impulses.

This, in turn, can reduce anxiety and promote relaxation without causing drowsiness, which is why research shows that supplementation with L-theanine . . .

  • Reduces the time it takes to fall asleep[21]
  • Improves restfulness after sleep[22]
  • Supports relaxation[23]
  • Reduces the effects of mental stress[24]

The clinically effective dose of L-theanine is 400 milligrams.

Lemon balm

Gamma Aminobutyric Acid (100 milligrams per serving)

Gamma aminobutyric acid (GABA) is a neurotransmitter that binds to receptors between neurons and reduces their tendency to “fire” and transmit nerve impulses.

This, in turn, can reduce stress and excitement and promote calm and restfulness, which is why research shows that supplementation with GABA . . .

  • May reduce the time it takes to fall asleep[25][26][27]
  • Improves the perceived quality of sleep[28][29]
  • Increases sleep efficiency[30]

The clinically effective dose of GABA is 100 milligrams.

Rutaecarpine

100% Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[31][32][33][34][35][36]

That’s why we use the natural sweeteners stevia and erythritol instead. Studies show that these ingredients are not only safe but can also confer several health benefits, including better insulin sensitivity, enhanced cholesterol profile, lower inflammation levels, and more.[37][38][39][40]

No Artificial Food Dyes or Other Chemical Junk

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

As with artificial sweeteners, artificial food dyes aren’t a hazard per se, but studies show they can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[41][42][43][44][45]

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
