I love purchasing supplements by NOW because I know I am getting quality products. I never have to worry about any added fillers or cheap ingredients. I have been using the brand for years and have never been disappointed. Ive been using this magnesium supplement for about one month to help me sleep. Ive had extra stress in my life (who hasnt these days) and it was really affecting my sleep and mood. I decided to try magnesium citrate as many people have had good response using it. I too can also say that it has been very helpful for me to fall asleep more quickly and stay asleep through the night.
