Melatonin - Optimal Levels ??

Hi All

Does anyone know where I can find what should be an optimal levels of Melatonin ?

I have done a web search, but cannot find anything at moment - maybe I am not searching the right question....

I have recevd back my saliva Melatonin test from Genova - and it just says within optimal range. Well we have all heard that on various tests !

It's a bit like being told that ferritin is 'in range' at 30 - but we know that is not an optimal level for a woman.

In case anyone on here knows about Melatonin optimal ranges or readings, here are my test results

Sample 1, - 07.00 - 09.00 > 1.9 < (range 1.0 - 10.0)

Sample 2 15.00 - 17.00 > 1.1 < (range 0.0 - 2.0 )

Sample 3 - 02.30 - 03.30 > 8.6 < (range 5.0 - 30.0)

Many thanks for any pointers

  • Hi JLt, I looked this up in my hormone book, but the levels and ranges it gave bore absolutely no ressemblance to the levels and ranges you have there. For one thing, it gave levels for 24 hrs, not three levels at different times. I don't know how to interpret them.

    However, even if yours aren't optimal, I have been told it is not recommended for a hypo to suppliment with it. Of course, I had to try! lol But the results were pretty bad. I only took it for two nights because I couldn't have stood a third!

  • Thanks Greygoose.

    I wonder if I added the 3 numbers together that would give the total over the 24hr period... would that then look anything like your hormone book ranges?

    Seems incredulous to me that one cannot find optimal levels of Melatonin like we can for B12, D3, Ferritin etc.

    feel I have wated my money!


  • No, I tried that. It didn't help.

    Maybe there is no optimal level... I don't know. But of course, there must be, otherwise it wouldn't have been in my book! lol Anyway, tell you what, I'll dig it out again tomorrow (got to go out now) and copy what it says, see if that helps you.

    Hugs, Grey

  • Hi! Sorry it's taken so long to get back to you, but I forgot who I was supposed to be answering and which question! lol Only just found you.


    OPTIMAL 100 pg/ml

    SLIGHT DEFICIENCY under 80 pg/ml

    MODERATE DEFICIENCY under 65 pg/ml

    SEVERE DEFICIENCY under 30 pg/ml



    OPTIMAL 50 to 130 ug/24h

    SLIGHT DEFICIENCY under 25 ug/24h

    MODERATE DEFICIENCY under 18 ug/24h

    SEVERE DEFICIENCY under 10 ug/24h

    So there you have it. Results for both blood and urine, but no saliva. It doesn't look like the blood results are 24 hours but it doesn't say what time the test was done. Hope that will be some help to you.

    Hugs, Grey

  • very many thanks Gregoose, appreciate it
