i found mag citrate really leveled out my energy production so its not so erratic(like my schedule! lol)
plus, get her some B-12 shots. only shots will really do. if she doesnt feel much from the first shot then B-12 is not a problem. that means iron is probably not a problem. if she does get a lot of good out of 1mg injected then do it every day until she can no longer feel the effects. look for liver flukes or possible dysbiosis.
