According to an article I read in a health magazine certain minerals and vitamins help you sleep better:
1. Calcium-This mineral helps calm your nervous system.
2. B Vitamins-It helps your body regulate trytophan is a sleep inducer.
3. iron-If you lack iron it could trigger a kind of restless leg syndrome which wakes you up at odd hours.
Do you know of other vitamins or minerals that help us sleep better?
