"Yes I did state earlier salt/minerals. Anyway, the point I was making is the the RDA (if it is even valid), may not apply when we are engaged in strenuous activities. But I am not a doctor... just a silly hiker."
I agree with Nick.
One thing is what you eat at home on a regular basis; high salts while exerting yourself should be fine, if not beneficial.
Also, "salts" include sodium, potassium, magnesium and a few more.
