I have PPMS (primary progressive multiple sclerosis). I also have been diagnosed with malabsorption in my gut that’s caused pernicious anemia (B12 deficiency). I am also taking very high D3. All of fat soluble vitamins are deficient in my blood due to the malabsorption. When I miss my B12 injection I have mental fog so bad my wife has my POA. I do take fiber chewable 4 a day. Life is hard for me and I am disabled by all of this.
