I buy the Source Naturals brand of magnesium malate and get it from Puritan's Pride. Recently, I noticed that Swanson vitamins carries magnesium malate also, but they were sold out. I'm wondering if that's a positive sign?
One thing I like about both Puritan and Swanson's is that they have paper catalogs, though some of their products are online only. I don't know about anyone else here, but I can only sit at the computer for a limited time period or my neck and back rebel big time!
I also buy my probiotic from Puritan's Pride ("probiotic acidophilus"). It's their own brand and it has worked well for me. Same with B-complex.
As far as D3, I've tried several brands and have never made any real comparisons. I'm currently taking a generic brand from my grocery store. Will be interesting to see what others have to suggest.
