These pills are quite large and because they are not coated they tend to get stuck in the throat and difficult to swallow so I would advise taking with lots of water, the dosage of total magnesium is 200mg I prefer the 400mg from Now so will go back to those as I need a large amount of magnesium daily but don't want the extra B6 in these pills.
