Welcome to a review of Melatonin Sustained by the Jarrow Formulas corporation. It is a product intended to be a jet lag treatment mean, as well as natural sleep facilitator. It supports the body’s healthy response to stress caused by jet lag and maintains a proper function of the pineal gland. Read on to get familiar with the product’s description.




Active ingredients:

Melatonin: a hormone produced by pineal gland, which supports body rhythm regulation.

Vitamin B6: supports metabolism of many hormones and enzyme reactions, including melatonin.

Inactive ingredients:

Cellulose, dicalcium phosphate, polyacrylate polymer, hydroxypropylmethylcellulose, stearic acid (vegetable source), silicon dioxide and magnesium stearate (vegetable source).

It is allergens-free: wheat, gluten, soybeans, dairy products, eggs, fish, shellfish, peanuts, tree nuts. It is a vegetarian/vegan product, suitable for gluten-free diet.


Each capsule contains 1 mg of melatonin, which is a minor dose (usually, in other remedies for jet lag it’s 3 mg). Take one pill approx. 20-30 minutes before the bedtime or as directed by the doctor.

Side Effects

The description of the product does not contain any side effects, but it mentions a wide list of categories of people who are advised to use the product only after medical consultation. The list goes as follows: pregnant, lactating, trying to conceive women, persons under 18,  taking medication (namely such as MAO inhibitors) or suffering from a medical condition (especially epilepsy, diabetes, asthma, MS, lymphoma, leukemia  or autoimmune disease).

The producer warns not to take the pill directly prior to driving or operating heavy machinery.


Amazon.com sells the product for $7.59 in case of monthly subscription or $7.99 when it’s one-time purchase. No other discounts are available at the moment, but even this price seems reasonable and does not exceed the average cost of the jet lag remedy. What’s more, the container contains 120 capsules which is enough for 4 months of the daily usage.


The guarantee is not given for this particular product. If you will not be satisfied with product’s effect, you have no right to return it and ask for a refund. It might be discouraging for many customers planning to purchase the product for the first time. In addition, the capsules have only 7 reviews on Amazon.com what seems insufficient to form an opinion about their efficiency. However, it needs to be reported that all reviews are very positive (score: 4.8 out of 5 stars).


The product is vegetarian/vegan, as well as free from many common allergens, which is a big asset. The manufacturer seems to treat safety issues with attention, stating openly all the restrictions of the usage, even though the dosage of melatonin is lower than in similar products, which abstain from providing this information in such an accessible way. The price is fair and reasonable for such an amount of capsules. One container of the product would be sufficient for 4 months of the constant usage. On the contrary, a low dose of melatonin might not be enough, hence the product could not work properly. Also, the small amount of reviews is not a trust-building factor.
