Melatonin: How much intake and how long before sleeping ?

[dsb9000]

Hello


1. Someone could tell us the quantity of food (ex: tomato) we should intake and how long before sleeping ? How can i know ?

On this site: <!-- m --><a class="postlink" href="http://www.dietaryfiberfood.com/melatonin-natural-sources.php">http://www.dietaryfiberfood.com/melaton ... ources.php</a><!-- m -->
there are some amounts.

According to this site: <!-- m --><a class="postlink" href="http://www.nutritionadvocate.com/webzine/story/melatonin.html">http://www.nutritionadvocate.com/webzin ... tonin.html</a><!-- m -->
children produce 120 pg/ml per day plunging to 20 pg/ml in the forties.

2. To reach the amount of commercially used (5mg) melatonin supplements we should take hugeeeeee amounts of fruits ? Is that necessary ?

3. Once seretonin is used to produce melatonin, is possible increase substantially the melatonin production by increasing the seretonin production ?

Thanks
