    I have been using melatonin for years, but in recent months I’ve been using some alternatives to melatonin and at times in addition to melatonin. I was interested in trying this product because it has a unique mixture of 10 ingredients that I have not seen in any other natural sleep aid product. The very first time I took this I could not believe how well it works. There is a very unique effect that it doesn’t zonked me out, but it is exceptionally calming and provides really deep relaxation. It feels like a very natural, undisturbed sleep that I have not experienced from other natural sleep aids. I wake up refreshed and well rested and it makes my day so much better. There is no grogginess whatsoever in the morning.
    One thing about sleep aids is I like to change it up from night to night. The reason is your body will get used to the ingredients and they become less effective. I like to use this product a few nights in a row, then skip a night or two and use an alternative natural sleep aid.

    I'm going to be moving in a few weeks, and I've been really anxious and stressed about it. I ordered this pills, hoping that they might take the edge off of my pre-moving anxiety. After using these for about 3 weeks, I've felt better and less anxious and stressed about the move. I am able to think more positively about the future, rather than worry about leaving my friends, starting a new life, etc. I also like that the dosage is just one capsule! I'm glad I ordered this supplement, as I can spend more time packing and preparing for my move rather than just freaking out about it. In terms of price, $43 for 60 servings is very reasonable.

    Saffron, an ingredient in this supplement, has already been an important part of my supplement regimen. This supplement also includes several other ingredients to aid sleep, mood and focus and to reduce stress. To while taking this, I adjust my other supplements according to what I'm getting from 1 capsule of SerotomixPlus. Since I've already been getting these ingredients, it's hard to tell a difference in all areas but I do think I'm sleeping better. I know saffron improves my mood and I'll never stop having that as part of my daily care. These are vegan and will last 60 days at 1 capsule a day.

    I do believe that these have a calming effect and help get to sleep. My partner has sleep issues and these with a cup of warm night time tea calm him down and let him relax and get to sleep. For that they get a five star as that is what they are for. Not sure anything more needs to be said other than in our experience these do help a man get to sleep.
