frayed or splitting skin usually indicates that you are short on zinc. But you have to take zinc with vitamins a and e. Also you don't want to take more than 30mg a day otherwise it WILL make you sick. Bath is the best way to get magnesium without getting too much or making your digestive tract upset. The thing is that magnesium helps your body process over 300 biochemical processes. If you are short and most people are because our diets lack magnesium, then you may not notice except that you feel off. It came up for me because I am not processing adrenaline or estrogen properly resulting in too much of both clogging up my system. The reason I posted this here though is that a LOT of people are asking about joint pain, tendonitis, blah blah blah, well magnesium (soaking in epsom salts) draws the toxins out of the joints. If you think about it, we are all training pretty hard. We need less recovery time and can lift more weight. We have seen phenomenal increases in our strength. All this training creates toxins and antioxidants in our system which need to be cleared out. I finally tried the salt bath the other day and quite frankly I was amazed at how much better I felt AND how it had loosened up my hip flexors and lower back which had been giving me MAJOR problems.
