400mcg is the typical dose of OTC folic acid. RX begins at 1000mcg or 1mg.
If you take B12, remember to take it on an empty stomach.
Your post suggests you are using 500mcg? 1000 would be better, since not much is absorbed orally in most people.
Make sure your magnesium is not OXIDE form. Any other type is OK, but Oxide is not absorbed and is basically a laxative.
