<<Disclaimer: Verify this information before applying it to your situation.>> Hello, All Recently had a bone scan which showed osteopenia. My doc has prescribed a calcium supplement and wishes me to take 1000 mg calcium a day (it has a 2:1 ratio of cal to magnesium). I started last night. Felt as if I was taking a natural tranquilizer at bedtime by taking this supplement (my second dose at bedtime). This morning I was OK and got a lot done around the house. Was looking forward to getting out and about his afternoon. But after lunch today (which completed the 1000 mg in a 24 hour period) I have been feeling out of sorts, tired, depressed, and somewhat headachy. I would appreciate any personal experiences with calcium supplementation any of you might have. I wonder if calcium dosage should be related to body weight. I'm a 110-lb woman. Do you think 1000 mg of calcium a day is too much? Has anyone had similar experiences? Has decreasing the amount of calcium helped? --- Latimer Kells --- [log in to unmask] --- EarthLink: It's your Internet.
