What about Redmond’s Real Salt? I’ve been using that for years. I’ve used pink salt sometimes, but after I read that it could be just regular salt tinted pink (and I didn’t know which brands to trust) I just stuck with Redmond’s.
You are going to get your highest mineral content from Celtic salt either way. The problem is it’s spendy. I use a good kosher salt for day to day. I mostly use the Celtic in bread and my Gatorade knockoff. Every morning I have a little Celtic salt with my morning water. Just a few crystals dissolved under your tongue is a good way to start the day.
