I have gingivitis as well and my new doctor took one look at my gums and the giant basket of supplements that I brought into her office and said, "you're malnourished. You're taking all of these supplements and you're trying really hard, yet none of it is getting absorbed". She quickly scheduled me for a vitamin drip this Tuesday called a "meyers coctail". It has magnesium, calcium, vit c and b complex in it. She also gave me a b12 shot which has had a very noticable impact on my energy levels. I felt very close to normal all day today. A month ago I was comotose. Today I did laundry, washed a boatload of dishes, organized my room, wrote emails, applied to New American Paintings, made fun of my dad by piling every blanket in the house on him because he was cold and it was funny and watched two movies with the sound on. I didn't feel sick once all day. It was a miracle.
