Here you can read a review of Melatonin manufactured by Natural Factors. The manufacturer claims that this supplement is perfect for customers who struggle with jet lag and have problems with their sleep. The product is supposed to reset the circadian rhythm, to increase and improve sleep time, and to reduce both fatigue and insomnia. Keep reading to find out more about its active and inactive ingredients and whether or not this would be a smart choice for you and your family.



Natural Factors Melatonin contains 3 mg of melatonin which is great for temporary resetting the biological clock, for fighting anxiety, insomnia and sleeplessness. It can also stimulate the body’s natural antioxidants production. Apart from this active ingredient the supplement also contains several inactive components such as:

  • Microcrystalline cellulose
  • Lactose monohydrate
  • Croscarmellose sodium
  • Natural peppermint flavor
  • Vegetable grade magnesium stearate

Please note that this is not a vegetarian product. This may be an issue for people with certain dietary restrictions. Moreover, the ingredient that has an animal source is lactose, so not only vegetarians, but also lactose intolerant persons should be careful with this supplement.


For best results, the optimal dose is that of one tablet each day taken 30 to 60 minutes before going to bed. Being a sublingual tablet, this means that it has to be placed under the tongue then swallowed after it completely dissolved. Although the manufacturer mentions that this product is also suitable for fighting jet lag symptoms it does not also mention if it is safe for inflight administration.

Possible Side Effects

Although it contains a considerable amount of melatonin, the active ingredient, the producer does not offer any type of detail regarding adverse reactions or possible side effects. There is no mention of administering the supplement to children to pregnant or nursing women or to people who are already on other prescription drugs. There is also no warning referring to a possible over dose.


Believe it or not, the price of this product is not available on the company website. After thorough research we managed to find that major distributors sell one bottle for about $10. Given the fact the one bottle has 180 tablets which translates to a 6 months’ worth supply of this supplement. In other words this product is supposed to provide you with better, more lasting and less stressful sleep for six whole months for only $10. We strongly believe that this sounds too good to be true, therefore the only possible explanation we could find is related to the product’s lack of effectiveness.


This company has no return or refund policy. If the results are unsatisfactory you can just accept the thought that you made a risky purchase. Since the manufacturer does not offer any type of guarantee we can only assume that this is related to a high volume of returned products due to their inefficiency.


All in all this remains an affordable product. It is very easy to take and it also has quite a pleasant peppermint taste. However the low price compared to other similar products can only be alarming. Equally concerning is the fact that the company does not offer refunds or accept returns. The bottom line is that we believe this supplement is nothing else but a risky purchase.
