If you are bipolar or schizophrenic, please be careful with calcium supplements. They tend to help my depression when taken with other vitamins. However, they also tend to cause persistent insomnia in myself. I usually take only 300mg per day because I cannot tolerate anymore than this, but over an extended period of time even 300mg of calcium carbonate causes restless nights, and then I have to resort to Benadryl to help me sleep. I really don't see the benefit to one's depression if calcium is also going to cause insomnia because even one night of zero sleep makes you feel like crap. You really have to be careful of all the supplements you take because many do cause insomnia, and you might not realize it right away. Also, I've had insomnia issues when taking Vitamin C before bed, so it is probably a good idea to take Vitamin C early in the day.
