where to get non prescription MELATONIN for adults ?

[54isanopendoor]

Ds used to be prescribed Melatonin as a young teen.
We moved area, changed GP, he is now turning 18 & won't go back & ask for it.
He agrees he needs it but wont' ask the GP: who isn't helpful - I've asked for some whilst awaiting my sleep clinic assessment (1 yr so far) & no help at all)

I looked on Amazon & see that Melatonin 'gummies' are easily availlable.
Are they of a useful strength compared to prescription ones or are they no good?

Did you find this? Get it from Biovea, their own brand time release.

EBay! We buy puritans pride brand.

I bought from piping rock based on this thread and it has already arrived and there were no customs issues. Thanks to those who recommended it.
