Loula, Thank you for your post. To clarify a bit further: B-12 shots are not used to treat Iron Deficiency Anemia (IDA).

Below normal B12 is Pernicous Anemia. I learned the hard way that low B-12 can make you feel quite horrible and prompt other serious problems. Ask your doctor about getting a simple B-12 blood test plus ask if it would be helpful to also get blood tests for homocysteine and methylmalonic acid (both of which can both go to abnormal levels due to low B12.) B-12 can easily be raised with B-12 shots and then your liver stores can be further maintained via oral B-12 pills (sublingual B-12 pills are easy peasy for me). Again, ask your doctor about this.

Iron Deficiency Anemia is very different ball game and unrelated to low-B-12. In my post above from several days ago, I list the tests that my doctor used to diagnose and continues to use to ensure I do not return to a state of Iron Deficiency Anemia.

It is possible to have both Pernicious Anemia and Iron Deficiency Anemia as I did BUT unfortunately, they are often confused. In fact, there are many types of anemias per this reference: https://www.mayoclinic.org/diseases-conditions/anemia/symptoms-causes/syc-20351360

PS Beet juice is FANTASTIC for many reasons but that's another story 🙂
