1- If you have plenty of meat, chicken in your diet and your B12 comes very low in blood results does that mean you have a "definite" absorption problem ?
2 - Does fish also a source of B12 ?
3 - if you have a definite absorption problem do sublinguals or sprays help( or work on you) ? Do they bypass your stomach and enter your bloodstream, therefore work even though you have an absorbtion problem ???
