Stress-Relax Tranquil Sleep Ingredients- Are They Safe and Effective?

The ingredient list for this product is short, has no harmful chemicals or drugs, and offers natural extracts to help you sleep better.

Take a closer look at the active ingredients used in this formula.


L-Theanine Often is used in natural sleep aids to promote better quality sleep[1], and is naturally occurring in tea leaves. Additionally, research indicates that L-theanine can enhance the quality of sleep. Its effectiveness in this regard is not attributed to its sedative properties, but rather to its ability to reduce anxiety and induce relaxation. Also, we have discussed about this ingredient in our Zleep reviews.

5- Hydroxytryptophan(5-HTP)

5-HTP is used in supplements as a precursor to the biosynthesis of serotonin and is often also used as an antidepressant[2].


Melatonin is a naturally occurring hormone that is associated with sleep with natural levels being the highest at night. Used in supplements to help promote sleep[3].

These three active ingredients are included in this formula to help provide an enhanced ability to fall asleep and stay asleep, improving the overall quality of rest.

What Do the Reviews Say?

Works, but not as well as advertised. The first few doses were promising, but the effects do not last long, and you feel burned out after its effect comes down.

  1. Dell Krauchi

    Not sure - maybe too soon to tell
    Good day,

    This product came highly recommended by a local health food facility.

    After three days of the use of Tranquil Sleep I, as of yet, have had no noticeable effective results with the use of Tranquil Sleep. As the staff was unable to assist me with my queries, I thought that it might be appropriate to contact the manufacturer directly, and presently awaiting a response from them.

    The following are the two questions that am seeking assistance with:

    Q1: In my research, I have noticed that some sleep-aid providers have suggested that employing such aids may take up to three weeks to become effective. Is this true of Tranquil Sleep?

    Q2: Is it appropriate to increase the dosage – say from 2 tablets daily to 3 or even 4 tablets daily?

    I hope this information will be of some practicable use.

    Probably works by Placebo Effect
    I’m in my 70s, and my daughter left me a bottle of these tablets to help me stay asleep, which has long been a problem for me. I’ve taken them for almost a month, and have found them to be of no use whatsoever, although they have a pleasant taste. I fall asleep easily, but wake up about 2 am unable to get back to sleep.

    I’ve since gone back to taking a single 25mg antihistamine tablet, which really works, and allows a full night’s sleep. Costs about $5 for a bottle of 100 tablets, as opposed to $42 for a bottle of 120 Tranquil Sleep tablets. I rate Tranquil Sleep a (1) out of (5). Waste of money.

  3. Rosalee Adams

    Only sleep aid that provides sleep & NO hangover
    I have tried it all, including RX. This product worked the first night. I chew 2 tablets half an hour before bedtime. I immediately fall go off to sleep and sleep without interruption. I wake up with no hangover as I experienced with other products.
