Vasopressin is also known as antidiuretic hormone because it reduces the quantity of urine produced by the kidneys during sleep. Older individuals secrete less vasopressin, and therefore tend to wake up more often to urinate.

There are also studies showing that interanasal vasopressin increases sleep quality among older subjects:

So my question is: are there supplements or foods which would increase vasopressin during sleep?

OK, so apparently no one has any ideas for increasing vasopressin production.

So how about the alternative of just using 20 IU of intra-nasal vasopressin before sleep?

The cost is fairly reasonable: 1mg of synthetic human vasopressin is 600 IU, and costs $42, So that's $1.40 a dose. Not super cheap but not insane either.

But is supplementing vasopressin a good idea or a really bad idea?

from what i remember vasopressin is released during sex and in circadian rhythms triggering amongst other things a release of hormones that alleviate stress (cortisol).
i recall anecdotes that the synthetics have virtually no effect and the best to get are the natural extracts (from porcupine.)
i haven't read anything about how it effects sleep but i always sleep well after a good go at sex.
vasopressin has been show to be released by the body during nicotine injections in cats though.
