Topical mag oil
Tonight i went to the health food store in my town and was asking the man who works there about a transdermal mag oil on the shelf. he is extremely knowledgeable in all areas regarding nutrition, supplementation, herbs, etc etc. BUT when i asked him about the topical mag oil, he said that it is useless and that taking it through the skin wont make any difference, that it needs to be taken orally in order to really increase levels. can anyone weigh in on this?
