1. Properly diagnosing the type of anemia is the first and most crucial step in ensuring that you receive proper treatment. The most common cause of anemia today is Iron Deficiency Anemia (IDA) but another common culprit, Anemia of Inflammation, can mimic IDA on blood work. When running any lab work to evaluate for anemia it is crucial to run the marker that tells these two apart- Total Iron Binding Capacity (TIBC). If you have been diagnosed with anemia in the past go look at your blood work and make sure that TIBC was run. If it was not run I strongly suggest that you get new blood work done to include that marker and have the results interpreted by someone who knows how to do so.
Sadly, running the appropriate blood work does not necessarily guarantee that the doctor will reach the proper diagnosis. I learned first hand that not all doctors are good at interpreting blood work. A few years ago I asked my GP to run some blood work for me that included an anemia panel. When the results came back I was told to take Iron despite the fact that my results very clearly indicated a different type of anemia! I believe that finding yourself a functional medicine practitioner who routinely orders such tests is the best way to ensure that you get the proper diagnosis and treatment.
There are many, many things that can cause anemia. Some are more obscure than others, while some are quite common. Make sure that you find yourself a doctor (preferably a functional medicine doctor) who is well versed in this area. Don't be afraid to ask them questions- it's the best way to judge weather they're worth their salt and it can give you a good indication of their character. It takes humility and guts for a doctor to admit when they don't know something, and I believe that their reaction to a question they don't know the answer to can tell you a lot of valuable information.
2. If you do need Iron or a vitamin, make sure it's a form that is easily digestible. I call the normal Iron pills "Home Depot special pills" because they look like Iron filings when they are ground. This form of Iron is not only poorly digested and notorious for causing constipation, but "inorganic Iron" such as this has now been linked to inflammation and Alzheimer's Disease.
3. The question needs to be asked, "why do you need this vitamin or mineral now?" Do you legitimately not get enough Iron or B vitamins in your diet, or is something hindering your ability to absorb them? Ulcer medications like acid blockers and proton pump inhibitors are notorious for causing IDA because you need stomach acid to break down the Iron in your food. Some people get B12-vitamin deficiency anemia because of an autoimmune disease called pernicious anemia.
