TLS I would assume that any natural way that increases your body to produce melatonin would be beneficial and not have the complication of watery diarrhea that some people get. I have tried oral supplements and oral spray with the same complication. Melatonin skin patches didn't give me diarrhea but...

Babi, Thank you for your input wrt your experience with melatonin. I am sure that most users of melatonin derive some benefit. But as this post indicates, there is a significant number of people that experience persistent watery diarrhea following melatonin supplementation. It took me awhile to make...

jmac, That is interesting. Different side effects for different people. You may now discover that others also share the same experience. Mountaineermd.

Somedude. Thank you for your input. If I find a supplement with melatonin that helps me sleep and does't cause the watery diarrhea side effect, I will post a follow up.

I am on this site because I have one copy of ApoE4 and my mother had severe AD. I have been practicing a healthy life style with diet and exercise. In hope of improv...

To reiterate the message of my original post, IF you are taking a melatonin supplement and you develop persistent watery diarrhea, STOP taking melatonin as that is the likely cause of the diarrhea. Robert Johnson MD

The stories are all very similar. I remember how relieved I was when I finally discovered the cause was a side effect from melatonin supplements. I know that it is a naturally occurring hormone, but taking it orally must be the issue. And I have no idea what the incidence of this side effect is, but...
