In holistic circles, people swear by magnesium. Magnesium glycinate in particular has worked really well for me. It makes sense, because magnesium is a co-factor for converting tryptophan into serotonin, which is turned into the hormone melatonin. So, you could try supporting your body's natural production of sleep hormones by ensuring you have enough available tryptophan and magnesium in your diet.
