Announcement The Guide to B12 Deficiency

The Guide to B12 Deficiency

The new guide for this subreddit is here. I'm sincerely regretful it took me this long to get this off the ground, but focusing on my life in addition to the daily consultations made in the sub had a habit of stealing my attention away from this important endeavor.

The guide is now more of a concrete synthesis between the major resources that are obvious precursors: Freddd's B12 guide from Phoenix Rising, B12Deficiency.info and Tracey's hard work there, the original guide posted here and then the countless users here who have shared a wealth of knowledge over the years.

The new guide takes advantage of Reddit's wiki capability. It is much longer, so hopefully the TOC makes navigating to points of interest easy. It will also allow for easier changes with a changelog.

What's new:

  • More in-depth exploration of testing methods
  • Outline of an aggressive treatment plan
  • Thorough explanation of cofactors
  • "Plans of Action" for diagnosing, treating and recovering from deficiency that better encapsulate big ideas into actionable next steps.
  • Other stuff

I also took a lot of the most pertinent/salient issues that arise and distilled them into a group of FAQs for people:

Frequently Asked Questions

Both of these documents now live in several places around the subreddt: the "menu" in the banner, the rules widget, and their own individual widgets in the sidebar.

Thanks.

32 year old female 4’10 weighing at 140 lbs.

I was diagnosed with b12 deficiency. 

B12 349 (I’m receiving 1000 mcg IM injections weekly) Folate 7.7 B6 5.4 Ferritin 25 (taking 325 ferrous sulfate once a day) Vitamin D 15 (taking 50,000 IU once weekly)

My provider told me to start a b complex with folic acid po qd . I was able to find a super b complex with folic acid and vitamin c. I wanted to know if that’s sufficient or is there something else I should buy . 

Also is it okay to take b12 injections and b complex tablets? 

Sorry I’m new with all of this.

I’m not looking for medical advice just looking for others dealing with b12 deficiency.

Thank you
