Apparently I am very low in vitamin D, B12 and lacking calcium.. I dont drink milk, I am gluten free and I am investigating thyroid problems waiting on results. I need a good source of reliable vitamins that work. Note : I also have lyme disease and co infections which I am going to be under treatment from a new .. lets not say doctor but former lyme sufferer tomorrow. I am desperate to figure out why I am so zombified all the time!!
