I use melatonin supplements frequently. Melatonin is a naturally occurring hormone made by the pineal gland that helps with regulating sleep patterns. They do help me fall asleep. I was told to use melatonin by my PCP. Now, I certainly don’t trust everything a PCP says. I always say that PCPs(internal medicine docs, general practitioners) know a little about a lot. As opposed to specialists, who are supposed to know a lot about a little. Sometimes specialists don’t give good advice though. (Can you tell I’m disillusioned with the medical field)? Anyway, I mentioned to my PCP that I was having trouble sleeping. He said to try melatonin supplements. They did help me sleep. Help, sometimes they don’t do a thing. I have read that melatonin helps after an ischemic stroke to promote neurogenesis(making new nerve cells) and to protect against future blood clots. Here’s an example. I have also read the opposite. I have read that you shouldn’t use melatonin after a stroke. Read this This isn’t a study from a peer-reviewed journal though. The overwhelming evidence seems to say that melatonin can be beneficial. Sooooooo, I don’t know! You can find whatever you want to find on the internet. You just have to know what’s best to believe and not believe. I use the supplements, so far no complications. As with everything else, I suggest you do your own research and make up your own mind about what to use/ not use!
