Doesn't RO take out all the good minerals water provides too?

Can someone recommend a good brand and source for an under-sink RO unit?
My mom discovered her water softener has been malfunctioning, adding salt
to the
water and increasing her blood pressure. At least that's the theory. So
I'd like
to get her an RO to solve the problem.

Water softeners by default take salt and substitute it for the mineral
ions in the water.

Changing from sodium cloride (table salt) to potassium cloride (potash)
as your water softener salt, will add potassium and not sodium to your
drinking water.

Check and see if you can get muriate of potash for use in the softener.
