Sorry... not normal. I'd start now on 5mg methylcobalamin each morning on an empty stomach. Do this for 3 months, and have a retest.... you should be over 1000 by then.

I'd hold off on the other foot for now. RSD which is a terrible chronic pain condition that is not understood well, seems to come to feet and wrists that have had trauma/surgery. It affects the sympathetic nerves, and creates terrible pain. RSD spreads, and will mirror to the other side of the body. So if you have left foot issue, it might show up on the right.

I'd really do the Vit C also...

This is just one paper, on PubMed on this subject. Work has been done in UK on this since early 2000's.

EsterC is easier to tolerate, a bit more expensive, but worth it I think. So I think you should immediately start methylcobalamin and Vit C as beginning interventions.

Here is my B12 thread:

Since the early 2000's the new lowest normal has become 400 in the US for B12 serum tests. Not all doctors are aware of this.

This link is in that thread, and also another by Dr. Snow MD at post #70... both were done for doctors Continuing Education, but laymen can understand them too.

It is best to start slowly with supplements at a level that your own history shows a weakness and need. You can always later add in things if you desire. B12 can be very effective for those with low levels in testing.

Methylcobalamin is the active form of B12...it is not commonly found in stores. But iherb.com , Swanson's and Puritan's pride all have it very reasonably priced. I tested out Puritan's last spring with great success, so now I use their brand. It is pennies a day. Can't beat that price!
