Sublingual B12 Help

I was unable to find information online regarding Trader Joe's B12, so please check the label to see whether it's cyanocobalamin or methylcobalamin.  You want methylcobalamin.

Sublingual B12 from Walmart. You can either get the 500 mcg or 2500 mcg. Both are pretty good tasting in berry flavor. Inexpensive, too.

The only sublingual I could find on Walmart's website was also the wrong form.

Supplement Facts: Serving Size 1 Microlozenge. Amount Per Serving - % Daily Value. Vitamin B-12 (As Cyanocobalamin) 500 Mcg - 8,333%. Other Ingredients: Mannitol, Crospovidone, Beet Juice Color, Natural Cherry Flavor, Vegetable Magnesium Stearate, Sucralose.

I am one month out. Is this ok to take until I can get the proper B-12? I'll get it in the next few days.

You're fine.  Honest.

Do not take the supplement that Heather Houston recommended.  As I advised her in another thread, this is not a variety of B12 that is readily absorbed by RNY patients.

You need to get METHYLcobalamin,  which is a more bioavailable form of B12 that we absorb much more easily.

Methylcobalamin is harder to find in stores, but readily available at The Vitamin Shoppe and online.  Based on all of the B12 products listed on their website (which I just checked), Nature's Bounty does not sell ANY methlycobalamin B12. 

WOW! Lots of information from FastFingers. I just started on my B12 last week. Barix Clinic sells the Bariaric Advantage at their Langhorne, PA facility. The label lists it as CYANOcobalamin. I am a little confused by the information presented because Barix Clinic is one of the leaders in bariatric surgery. Why would they be offering a product that is not absorbed well by RNY patients? I guess I'll be calling them in the morning to get clarification.

I'm a Barix baby, too.  We need to be our own best advocates when it comes to this stuff.  Your nutritionist is clearly not as well informed as she should be.

Vitamin B₁₂

Vitamin B₁₂ has the largest and most complex chemical structure of all the vitamins. It is unique among vitamins in that it contains a metal ion, cobalt. For this reason cobalamin is the term used to refer to compounds having vitamin B₁₂ activity. Methylcobalamin and 5-deoxyadenosyl cobalamin are the forms of vitamin B₁₂ used in the human body (1). The form of cobalamin used in most supplements, cyanocobalamin, is readily converted to 5-deoxyadenosyl and methylcobalamin in the body. In mammals, cobalamin is a cofactor for only two enzymes, methionine synthase and L-methylmalonyl-CoA mutase (2).

Existing evidence does not suggest any differences among forms with respect to absorption or bioavailability. However the body’s ability to absorb vitamin B12 from dietary supplements is largely limited by the capacity of intrinsic factor. For example, only about 10 mcg of a 500 mcg oral supplement is actually absorbed in healthy people [8].


In other words, Al, our bodies have to TURN cyanocobalamin INTO methylcobalamin to make use of it.  Because we're already at a disadvantage since we're producing insufficient intrinsic factor to absorb B12 in the first place, the LAST thing we need to do is to make it harder for our bodies to USE the little bit of B12 we do get.

You should share this information with your nutritionist at Barix and let her know that she should be selling METHYLcobalamin, since it is more bioavailable for us after RNY. 


 

Thanks!!

I have watched these boards continuously for the last 7 months and this is the first mention I've heard of the methylcobalamin vs. cyancobalamin B-12 . 

Alsolanik, I am inclined to believe that whatever  Bariatric Advantage's B-12 Sub is ....... that  is definitely the one I would go with too.  

Are there any studies to back this up Fast Fingers?

I get the injections monthly .... supposedly the best absorbed way to get in your B-12.
