Name and Basic Overview

Natural Factors, Stress-Relax, Tranquil Sleep is a dietary supplement designed to promote relaxation and improve sleep quality. It combines 5-HTP, Suntheanine® (a patented form of L-theanine), and melatonin in a chewable tablet form.

The supplement is suitable for vegetarians and vegans and is non-GMO verified. People commonly seek this supplement to aid in stress reduction and to enhance sleep, particularly for those experiencing difficulty falling or staying asleep.

Historical Background / Traditional Use

5-HTP is derived from the seeds of the African plant Griffonia simplicifolia and has been traditionally used in African medicine for its mood-enhancing properties. L-theanine, found in tea leaves, has been used in traditional Asian medicine for its calming effects. Melatonin is a hormone naturally produced by the pineal gland in the brain, historically used in modern medicine to regulate sleep-wake cycles.

Composition and Active Components

• 5-Hydroxytryptophan (5-HTP): A precursor to serotonin, a neurotransmitter that plays a role in mood regulation and sleep. It is believed to help increase serotonin levels in the brain, potentially improving mood and sleep.
• Suntheanine® (L-Theanine): An amino acid known for promoting relaxation without drowsiness. It is thought to enhance alpha brain wave activity, which is associated with a state of relaxed alertness.
• Melatonin: A hormone that regulates the sleep-wake cycle. It is commonly used to help with sleep disorders, such as insomnia or jet lag, by signaling to the body that it is time to sleep.

Research and Evidence Base

5-HTP: Some studies suggest that 5-HTP may be effective in improving sleep quality and reducing the time it takes to fall asleep. However, more robust clinical trials are needed to confirm these effects.

L-Theanine: Research indicates that L-theanine can promote relaxation and improve sleep quality, particularly when combined with other sleep-promoting compounds. A study published in the "Journal of Clinical Psychiatry" found that L-theanine supplementation improved sleep efficiency and reduced sleep disturbances.

Melatonin: There is substantial evidence supporting the use of melatonin for improving sleep onset and duration, particularly in cases of insomnia and circadian rhythm disorders. A meta-analysis published in "PLOS One" confirmed melatonin's efficacy in reducing sleep onset latency and increasing total sleep time.

Overall, while the individual components of this supplement have shown promise in improving sleep and relaxation, the combination's effectiveness may vary among individuals. Further research could provide more definitive conclusions on the synergistic effects of these ingredients.

Potential Health Benefits

• Supports Relaxation and Sleep Quality: The combination of 5-HTP, Suntheanine® (a patented form of L-Theanine), and melatonin is designed to promote relaxation and improve sleep quality. 5-HTP is a precursor to serotonin, which can help regulate mood and sleep. Suntheanine® is known for its calming effects without drowsiness, and melatonin is a well-known sleep aid that helps regulate the sleep-wake cycle.
• Fast-Acting Formula: The chewable tablet form allows for quicker absorption, potentially leading to faster onset of effects compared to traditional capsules or tablets.
• Suitable for Vegetarians/Vegans: This product is suitable for those following vegetarian or vegan diets, broadening its appeal to a wider audience.

Safety, Side Effects, and Precautions

• Gastrointestinal Upset: Some users may experience mild gastrointestinal issues such as nausea or diarrhea, particularly with 5-HTP.
• Drowsiness: As melatonin is a sleep aid, it may cause drowsiness. It is advisable not to operate heavy machinery or drive after taking this supplement.
• Allergic Reactions: Although rare, some individuals may experience allergic reactions to any of the ingredients.
• Specific Populations: Pregnant or nursing women, children, and individuals with autoimmune conditions or those taking medications for depression should consult a healthcare provider before use.
