Definitely good. Epsom salts (magnesium sulphate) can be very inexpensive, depending on which isle you buy it from. It's used in a bath for sore muscles, internally as a laxative, and in gardening as a fertilizing supplement for your plants.

My wife got a bunch of bulk magnesium somewhere. Not sure where.
We make out own electrolyte drinks with bulk magnesium. Much healthier than what the store provides.
