Осторожно с Кава-Кава! В Канаде ее больше продавать не будут. Здесь об этом есть -

Мелатонин тоже в Канаде не продается официально, надо по инету заказывать. У меня есть статья из Nutrition Action Health Letter, я уже где-то упоминала, что я выписываю этот журнал, так вот, статья как раз о добавках, которые якобы помогают при инсомнии. Вот некоторые цитаты:
Asleep at the switch.
If you shop for these supplements in the U.S., you may have seen these three products. Don't fall for the hype.
Alluna. Valerian plus hops is sold in Europe to help people sleep. GlaxoSmithKline, which sells the Alluna brand in the U.S. claims that clinical studies with more than 3,500 people show that it "helps people fall asleep faster and sleep more soundly". Yet thte gian drug company could only come up with one study - in 18 people - that compared Alluna with a placebo. And it only showed that the supplement could be safely taken by those who use heavy machinery or drive.
Natrol Stress Complex. Natrol claims, that the six B-vitamins in its Stress Complex (which also contains valerian and melatonin) "play a crudial role" in getting proper sleep. But the threee studies the company sent us had nothing to do with sleep (or stress). They didn't even use the same combination or levels of vitamins found in Stress Complex. And the consultant Natrol referred us to said that she has advised the company to drop its claim about B-vitamins and sleep.
Kava Chews. Chew on them and you'll fall asleep faster, says the manufacturer. While kava may help people who suffer from clinical anxiety relax, there are no studies showing that the herb helps people fall or stay asleep. And the latest news may keep kava-users awake: More than two dozen cases of liver toxicity in Europe and the U.S. have been linked to the herb. Health Canada has advised consumers not to use any products that contain kava.

Sleep boosters
-People who exercise regularly fall asleep faster, sleep for a longer time, spend less time awake during the night, and get more of the deeper slow-wave sleep than people who don't exercise.
-A warm bath can help you fall asleep, because it raises body temperature; the subsequent cooling triggers sleep.
-Covering your eyes with a mask or towel may help you sleep better. If melatonin leevels are exquisitely sensitive to light, as recent research suggests, the darkness may promote sleep by keeping your body's natural melatonin levels up.

Melatonin.
Taking melatonin is not going to help with the garden variety of sleep problems most people face, says Andrew Monjan, Chief of Neurology of Aging at the U.S. National Institute on Aging in Bethesda, Maryland. Studies have shown it to be effective in improving sleep quality usually only for people whose waking and sleeping is out of sync with the daily cycle of light and dark, such as with shift work, jet lag or blindness.
**
The bottom line: If you have jet lag or your body clock is out of sync, melatonin may help you reset it. But if you can't sleep for any other reason, melatonin probably won't help. Researchers have never tested its long-term safety.
С валерианкой - сон я бы нормальным не назвала. В смысле, что это беспокойный и тяжелый сон, от которого просыпаешься утром уже усталым с деревянной головой. И чтобы придти в себя именно нужно кофе пить. Или у Вас не так?
