Sally’s response:
For vitamin B12, you can take sublingual tablets — Jarrow makes a good one, I take it myself. For a more detailed explanation of my thoughts on B12 supplementation, please see the below excerpt from my article entitled Vitamin B12: Vital Nutrient for Good Health written with Mary Enig, PhD:

In these pages, we have consistently advised obtaining vitamins from food (including superfoods) rather than with vitamin supplements. One good reason to avoid supplements derives from research indicating that they can interfere with B12 uptake, exacerbate the symptoms of B12 deficiency or even cause the creation of B12 analogs that increase the body’s need for B12.

However, when it comes to B12 itself, supplementation with isolated B12 is often necessary and appropriate. The many factors in our modern lifestyle that block the complicated uptake pathways of this important nutrient–from nutrient deficiencies to exposure to toxins to factors in processed foods that cause reduced stomach acid, autoimmune disease and enzyme disruption–make it difficult to obtain sufficient quantities from our normal diet; and since vitamin B12 in supplements is produced in exactly the same way as B12 in nature, that is, by bacterial fermentation, the danger of high doses in most cases is negligible.

B12 supplements have the potential of making life better for a large portion of the population, and not just the elderly. Regular testing and treatment with supplements as needed is an important step in the transition from the modern diet back to a nutrient-dense traditional one, when, after a generation or two, supplements of any kind will no longer be needed.”

You need vitamin A to absorb iron, so the first thing would be cod liver oil, which is also absolutely essential for the adrenals. Then to eat iron rich foods — liver, red meat, beets, molasses.
