I prefer Magnesium Chloride flakes over Epsom salts but its a fair bit pricier also. Also it can make you very relaxed so best used at nighttimes.. & not before an important meeting etc LOL
Iodine, I wouldn’t bother, it would ether be so diluted as to be wasted or you’d have to use so much it wouldn’t be practical, economical & you’d end up looking like an oompa loompa.
The clay would probably work better used as a mud mask/body wrap and then rinsed off as apposed to dumping it in the water.
I’m not sure about Bentonite clay but I use Rhassoul clay to wash my hair & you can add stuff to it (essential oils, emu oil etc)
Essential oils.. just make sure its nothing your sensitive to. Oh and peppermint has an icy cold effect on the skin
