I'm taking Mg as part of Freddd's b12 protocol and have been getting symptoms of b12 deficiency (sore muscles, extra fatigue and longer recovery time) when moving on to new stages. When this first happened, I had stopped taking Mg because tablets gave me diarrhoea so I started taking Mg in the form of an oil spray (2x 180mg/day). This did the trick. However, I have recently started getting sore muscles etc. again so I upped the dose, with no effect. Last night I took an Epsom salts (150g) bath with no immediate relief and afterward sprayed on 180mg of Mg in oil. For the first time, the oil made my skin sting slightly. According to the packet (and other sources I've seen on the net) this is a sign of Mg deficiency and stops when you are no longer deficient. I hadn't had the stinging before and wondered if it was because the hot bath had opened my pores and I was absorbing the oil better. I don't usually seem to absorb the oil well - it seems to sit on my skin and even after 20 minutes my skin is still sticky. I'm wondering: 1. Is 2x 180mg a day a low dose? 2. Is there a better deliver method through the skin? I've seen you can get Mg gel, that people dissolve Epsom salts into cream and rub it in, and so on. I'd like to hear how people are getting on with this and how much Epsom salts would be the equivalent of what I'm using now.
