I'm not a doctor, and I'm not giving you medical advice, just some insight on magnesium.

People take vitamins while taking meds all the time. You might just research to make sure if they can be taken at the same time, but if it was me, I'd try to take them at different times just in case they interact.

From what I've read on the subject, you should take magnesium on an empty stomach as it needs stomach acid to process it so to speak. Be sure and take the calcium and vitamins D3 and K at the same time as they all work together.
Early in the morning and in the afternoon are the times the book I read [The Magnesium Miracle] suggest taking it.

One thing people don't understand about the RDAs the FDA puts out is that what they recommend is the minimum amount needed to keep you from dying of a deficiency of that supplement. For example, the RDA of iodine is 150 mcg whereas a top iodine doctor recommends 12 mg as that's what the body needs a day to be able to do perform all the functions iodine is needed for. the 12 mg is 80 times the RDA. The 150 mcg is just enough to keep you from growing a giant goiter on your neck, not enough to build your health. Another example is vitamin C. The RDA is around 60 mg which is just enough to prevent you from dying of scurvy and your teeth from falling out. The same is true for most other nutrients including magnesium.

If you take magnesium chloride, you won't have nearly the issues with it causing diarrhea that the other forms do. Same if you supplement with epsom salts that are magnesium sulfate by soaking in a tub of them.

I think you'll be absolutely amazed at how much better you feel when you find the right amount of magnesium for your body.

Another thing that will help your depression is taking a high quality nascent [ionic] iodine assuming you don't have hyperthyroidism or Hashimoto's Disease. I've taken iodine for years, but once I started using nascent iodine about 4 months ago, I really noticed how I haven't been the slightest bit depressed in spite of some serious family issues that have been upsetting. I also haven't developed my yearly SAD that strikes every fall as the days get shorter. This year my mood incredibly stable--happy without being hypomanic, and I'm sure it's the iodine. The other crazy thing the iodine has done is that it's turning the white in my hair back to gray--I started going gray at 21, and have been almost completely gray since I was in my early 40s so this is very exciting. I have some thinning on top that is also filling in, and the only explanation is the iodine. It's worth it's weight in gold for my mood and my hair.

Here's a video by the doctor whose product I use.
