Im on both also along with Iron and its all due to low numbers except Iron for some reason I can't absorb it as well as others. My Hematologist keeps an eye on it. But I will admit maybe due to age or just like @rosy54 said maybe there is something to the absorption. I do eat a lot of iron rich foods mostly spinach, i love in salads. But i find a nice nap in the afternoon helps a lot also.

@rosy54 I may ask about what you said as my iron levels were ok but my absorption was only 17% and my hematologists put me on Iron Pills. Im 9 % Italian from Sardina but mostly British based on a dna test. Which explains my love of Mediterranean food. Interesting find.
