I was planning on buying kelp and celtic sea salt from here:

http://www.celticseasalt.com/

Reason is because I am using infrared sauna and a book I read said to replace minerals with sea salt and kelp. so what should I do? is there no good kelp brand? or how can i replace what kelp was gonna benefit cheaply?

It seems that sea salt might have a lot of minerals in it and i was looking forward to kelp maybe helping with iodine becasue i know i'm deficient. I'm profoundly exhausted all the time and since i was even young. I was gonna put the sea salt in my water to replenish minerals lost and hopefully make progress on deficiencies.
