Thank you for answering, yes it doesn't say how much, but it contains magnesium stearate, I don't have D all the time, but my problem is I go the the bathroom at least 3 times a day or sometimes more, I was diagnosed with IBS, but I don't have the pain like some have, but it's inconvenient to always be looking for a bathroom when I go somewhere. Thanks again, I'll try these and then if they don't work, will get the Caltrate.
