hhhhmmmm... I tried posting this about an hour ago, but it never showed
up. I'm sorry if this is a repost.

I don't know for sure, but I would imagine that there is probably no
defined RDA for milk thistle, as it is not an isolated component. Of
the few supplements I take, the lables tend to have a lot of *'s on
them because there is no RDA for many of the whole food ingredients.
I've never heard of using milk thistle for insomnia, but that doesn't
mean it couldn't be used as such. Most applications of milk thistle
have to do with some sort of detox program since it supports the liver.
How long have you had insomnia? Can you possibly trace your insomnia
to particular foods? The first things to look for is food or drinks
that contain caffeine.

"As caffeine stimulates the central nervous system, it has also been
linked to insomnia, nervousness, and anxiety. It is also a cardiac
muscle stimulant, a diuretic, and a stimulant of gastric acid secretion
in the stomach."

"29 Secrets to a Good Night's Sleep"
One of the recent pieces of advice I used from that page is a sunrise
alarm clock. I didn't buy the one Dr. Mercola sells because it's too
expensive. Better than the sunrise effect it has for waking me up, I
especially like the sunset effect you can use to help you go to sleep.
After using it for less than 3 months, I find that it's now hard to go
to sleep without turning on sunset. I find it very relaxing.
Hope that helps.
Max.
