This is a review of Melatonin Tablets manufactured by Sisu. The product helps to increase total sleep time in people suffering from sleep restriction or altered sleep schedule, e.g. jet lag or shift-work. It also helps to relieve daytime fatigue associated with jet lag and gives a feeling of a restfulness. For more information, check out the review below.




It contains 5 mg of melatonin per tablet.  Melatonin is known as the sleep hormone, since the lack of it results in sleep disturbances. It is secreted when it gets dark, and its production is suppressed during the daytime. Long-distance travels or regular shift-work can also affect the process of its secretion.

Inactive ingredients are: isomalt, microcrystalline cellulose, magnesium stearate (vegetable), croscarmellose sodium, calcium silicate, natural mint flavor.

Contains no wheat, gluten, peanuts or soy, sweeteners, artificial colors or flavors.


For insomnia: take 1 tablet daily before bedtime.

For jet lag: take 1 tablet daily before bedtime, 3 days before the flight and 3-5 days after arrival.

Dissolve the tablet under the tongue. Since it gets directly to the bloodstream, it will work faster. You can also dissolve it in a liquid and drink it.

Consult a health care practitioner for use beyond 9 weeks.

Warning: Melatonin should only be taken at bedtime, whatever time of the day that is for you. It should not be taken before work that requires close attention.


The producer warns about the possibility of the occurrence of fatigue, confusion, sleepiness, and disorientation. It also assures that the product is non-addictive and does not produce the “hangover” effect , unlike many prescription sleep-aid drugs.


The cost of the product is $14.99 for 90 tablets. Since the container is bigger than usual and will be enough for 3 months, the price is reasonable. Although, the shipment cost is high ($9.99) which makes the product quite expensive for its quality.


Sisu doesn’t provide a guarantee for the tablets. Therefore, the purchase becomes a bit hazardous, as there will be no refund in case the product will appear ineffective. In addition, there is only one review on It is very positive, complimenting the quick effect of the pills, but it is not enough to feel assured about the product’s usefulness. We put some effort to find other reviews and on other websites the situation is similar – inconsiderable amount of opinions.


The most positive thing about this product is that it’s specifically designed for jet lag and provides clear directions how to use it properly when a person struggles with this condition. The product is also natural, therefore safe and non-addictive, suitable for various groups of people, like Vegans, Vegetarians, allergy sufferers.  The price is reasonable, but unfortunately the shipment is expensive, which increases the overall cost significantly. Another disadvantage is that it is hard to find reviews, which would give a picture of the product’s efficiency. The ones that we were able to find are not enough to establish a clear vision on this matter.
