Trader Joe's has 500mcg (i.e. 0.5mg) tablets. Walmart had 300mcg tablets, which were absolutely ideal, but they've stopped carrying them locally. There was an excellent article I read a few years back which made the case that 300mcg is the ideal dose for nightly use. Over 1mg, the body adapts to it and it loses effect. The smaller tablets are preferable to breaking larger ones, since it's hard to be consistent due to the manner in which they crack, as well as the potentially uneven distribution of melatonin to filler in each tablet.
