Natural Factors Stress-Relax Tranquil Sleep Chewables is convenient and easy to use!

Let’s take a look at each of these sleep-promoting nutrients and how they may become your favorite new addition to your bedtime routine!




  • L-theanine (Suntheanine): This ultra-absorbable, clinically-studied form of L-theanine plays a key role in healthy brain function. It helps regulate circadian rhythms, which can be helpful for better sleep at night and sharper focus during the day.* Plus, this natural sleep proponent supports a healthy response to everyday stress and promotes relaxation.*


  • Melatonin: Known as the sleep hormone itself, melatonin plays a central role in healthy sleep quality. Supplementing with this important nutrient encourages the body’s natural ability to feel tired closer to bedtime and more awake in the morning.* Additionally, combining melatonin with other sleep-promoting nutrients can be helpful as part of a more complete bedtime routine.*


  • 5-HTP (5-hydroxytryptophan): This amino acid is essential to serotonin and melatonin production, two key compounds involved in quality sleep. Plus, it may help with a balanced mood.*


Deep, restful sleep doesn’t have to feel unattainable! With the help of sleep-promoting nutrients, your best rest may be closer than you think.* Buy Natural Factors Stress-Relax Tranquil Sleep Chewables and enjoy a quick, convenient, and soothing way to wind down at bedtime.

FAQs About Natural Factors Stress-Relax Tranquil Sleep Chewable

Q: Does this have melatonin in it, or is it just herbs and amino acids? A: Yes. You get 3 mg of melatonin per 2 chewables. It also has 200 mg of Suntheanine L-theanine and 30 mg of 5-HTP, so it isn't a melatonin-only formula.

Q: How should I take this at night? A: Chew 2 tablets at bedtime. I’d take them about 20 to 30 minutes before you want to be asleep.

Q: Why does this use Suntheanine instead of just regular L-theanine? A: Suntheanine is just a branded form of L-theanine. Some people specifically look for it because they recognize the name. Here, 2 chewables give you 200 mg, which is a pretty normal bedtime amount.

Q: I've heard that 5-HTP can interact with medications. Should I be careful with this one? A: Yes, I would. This has 30 mg of 5-HTP, so I'd check with your pharmacist first if you take antidepressants, mood meds, or anything else that affects serotonin.

Q: Will this make me groggy the next morning? A: Maybe. The 3 mg melatonin is a pretty reasonable amount for a lot of people, but if you're sensitive to sleep aids, you might feel a little slow the next morning.

Q: My doctor said to watch added sugar. Does this have much? A: A little. Two chewables have 3 grams of sugar, and all 3 grams are added sugar. Total calories are 15.

Q: Should I use this if I'm pregnant or nursing? A: I’d wait unless your provider says it’s okay. Talk with your OB or midwife before starting this one.
