Take 4 tablets 30-45 minutes before bed. Lunar can be used daily without harm, but you may notice greater benefits if you cycle your intake, such as taking Lunar daily for 4-6 weeks followed by a 2-week break.

Legion Lunar | All-Natural Sleep Aid Supplement

Q: How quickly will I see results with Lunar?

Many customers report immediate improvements in sleep quality with Lunar.

Q: Are there any side effects I should know about?

There are no side effects you should know about, other than better sleep. We were very careful when creating this formulation to avoid natural sleep aids known to cause side effects and/or withdrawal symptoms, such as valerian root, skullcap, and kava. Instead, we chose ingredients that are scientifically proven to help you relax, fall asleep faster, stay asleep longer, and wake up feeling refreshed . . . without unwanted side effects.

Q: Will I become dependent on Lunar for good sleep if I use it regularly?

No, you will not become dependent on Lunar to sleep well. If you stop using it altogether, there are no residual effects.

Q: Why is there so little melatonin in Lunar?

There is so little melatonin in Lunar because research shows the benefits aren’t dose-dependent. [1] For this reason, we chose the low end of the clinically effective dosage range of melatonin. Furthermore, taking high amounts of melatonin increases the risk of side effects like difficulty waking up and morning lethargy and grogginess. 1 http://www.ncbi.nlm.nih.gov/pubmed/23691095

Q: What does the Prop65 warning on the labels mean?

Our products include a Proposition 65 warning in compliance with California’s regulatory guidelines, which are among the most stringent and sweeping in the world. A Proposition 65 warning does not indicate whether a product is safe or unsafe. Rather, Proposition 65 is a consumer notification law in California that requires warnings to inform consumers about the presence of one or more of over 900 substances in various types of products. These substances include naturally occurring and ubiquitous compounds, even when present at levels below those known to cause harm.

Q: Is Lunar gluten-free, vegetarian, or vegan friendly?

Lunar is gluten-free, vegetarian, and vegan friendly.

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.[8][9]

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.[10]

The clinically effective dose of glycine is 3 grams.

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[11][12]
Can improve sleep quality[13][14][15][16]
Reduces symptoms of jet lag[17]
Can improve memory function[18]

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.[19]

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[20]
Improves restfulness after sleep[21]
Supports relaxation[22]
Reduces the effects of mental stress[23]

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

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[24][25][26]
Improves the perceived quality of sleep[27][28]
Increases sleep efficiency[29]

The clinically effective dose of GABA is 100 milligrams.

Naturally Sweetened and 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.[30][31][32][33][34][35]

That’s why we use natural sweeteners like stevia, erythritol, and monk fruit instead. Research shows that these ingredients are not only safe but can also confer several health benefits, including better nutrient absorption, healthy cholesterol and inflammation levels, and more.[36][37][38][39]

No Artificial Food Dyes or Other Chemical Junk

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[40][41][42][43][44]

That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.
