I certainly think its possible. I did do the wrist painting and my spots wore off in 6 hours or so, indicating some deficiency, yes? If I did get any detox symptoms I honestly couldn't tell.
Its not that I didn't notice some possible things, but I could not 100% verify if there were any real changes occurring. I'm not sure you can saturate the body with the required amount for health so quickly without paying the piper somewhere. I guess, if I had cancer I may try this route again.
But for me, I've decided to go the slower natural route and see what happens in a year or so. Good luck.
