Gotta love all the clever inquisitive minds among our integrative health practitioner community.   I think each of us, as children may have been that one kid who just never stopped asking questions.  What a great quality to have because it prompts us to think outside the box, then outside the triangle, then the hexagon and beyond! Simultaneously, busy minds that never stop questioning and never quiet down can also feel like a curse!  None of us have the time to go find the answer independently to every single question that our patient, prescription & pathology encounters raise for us.  We need to use the force. Our colleagues, our workmates, our informal and formal practitioner networks, our mentors, our associations, our educators etc.  A lot of practitioners recently got some questions answered with the Update in Under 30: Separating the B12 from the B*S#!...and then guess what…they had some more B12 related questions 😂😂

Q: What might a normal or even high serum B12 together with low Active B12 combination flag in a patient?

A: Exclude COCP use, & gross liver pathology, refer for B12 antibodies if possible & review the case for other evidence of functional B12 deficiency, as TCII values are more specific and sensitive than serum

Q: What evidence do we have to use a higher cut-off value than the labs give us for Serum B12 (< 400 pmol/L), as a decision limit for follow-up investigation for B12 deficiency

A: Just the findings of some of the biggest studies on B12 assessment – correlating serum values and markers of functional deficiency such as Harrington et al 2017, Spence et al 2016, which flag that there is already metabolic impairment typically when serum values drop below 400, well before the classic features such as macrocytic anaemia

You’re welcome 🙂 It’s nice to be surrounded by like-minded curious kids (disguised in big people’s bodies!)  I love playing my part in adding to the collective knowledge in different ways and for those of you who are our Update in Under 30 subscribers, and of course anyone that purchased this as a single download, well we’ve gone that extra step and put together a nice little pdf: A B 12 Assessment Decision Tree for you and added that in as a bonus to your Separating the B12 from the B*S#! episode.  So go take a look now and hopefully that answers just a couple more questions and we can all have at least 1 good night’s sleep… before you come back with more 😉 🧐 😂

Separating the B12 from the B*S#! 

B12 is a routinely under-rated and recognised micronutrient, which is in fact in high demand by many of our patients. As nutritional research pushes back against defining adequacy as simply the prevention of the deficiency-associated disease (macrocyctic anaemia, irreversible neurological damage) we enter a new landscape of more individualised approaches where we’re better able to recognise and treat those at risk of falling below ‘optimal’.  But how do we accurately identify this and then choose the ‘best’ B12 (methyl- cyano- adenosyl- hyroxo-) supplement? Does it need to be this complex?  Time to sort the B12 from the B*S#!!
This recording comes with a bunch of great resources including a clever clinical tool.  
And now a new one to boot!!
