1.0 mg is a good starting size. If needed you can always take more than one pill.
For difficulty in getting to sleep, chose 1.0 mg regular release.
For difficulty in staying asleep, try 2.0 mg sustained release capsules.
300 mcg
Dosage is 4 tablets totaling 1.2 mg. This size is for beginners who want to try a smaller dose than the 1.0 mg, 2.0 mg, and 3.0 mg size.
Sustained release allows for a continual release of the melatonin over the space of a normal sleeping period.

Regular release delivers its effectiveness as it is digested, which is a relatively short time. It is best as a boost to get to you to sleep, but not necessarily to keep you asleep.

Active Ingredient:  Pure, pharmaceutical grade Melatonin.

Other ingredients serve as fillers and binders. They are -

Tablets: Croscarmellose SodiumDi-Calcium Phosphate
Magnesium Stearate  and   Stearic Acid.

My effective doses of melatonin
Up until several years ago, I had been using 1.5mg for quite a long time and it worked very well. I was able to fall asleep very quickly. Then, for some unknown reasons it suddenly stopped working. As, at that time, I still kept an old bottle of it, I compared a new one and the old one with a friend (middle age, not using melatonin). Well, the old one worked perfectly well for both of us, and the new one was disappointingly not effective for both of us.

Since then, I tried various doses of it hoping to find the reasons. I also tried other brands, such as Source Naturals 1mg. They were not so effective, either. I still don't know why it suddenly stopped working. I already noticed the Source Natural brand and others were not very effective before that happening.

Then, recently I tried lower dosage tablets, 1mg or even lower 0.3mg, and found they were more effective than higher dosages. So far, the most effective dosages are between 0.6mg (0.3mg x 2tabs) and 1.6mg (1mg + 0.3mg x 2 tabs). But, still not so effective as the old 1.5mg.

I miss the good old 1.5mg very much.
