Low Vitamin B12/d...6+ Years Post-Diag?


canadave

Recommended Posts

Hi,

 

I was diagnosed with celiac (with biopsy) and went on the gluten-free diet in 2008 (when I was 37 years old).  I just had some blood work done, and it shows I have low vitamin B12 and vitamin D levels, both of which my GP told me were likely related to my celiac disease.  And, I have indeed read that low levels of these vitamins can be caused by celiac disease.

 

I guess my question is whether that is true of people who have UNTREATED celiac disease, rather than people who have celiac but have been following a strictly gluten-free diet for years.  I thought that years of being on a gluten-free diet would've allowed my insides to "heal", and thus I thought these kinds of issues wouldn't necessarily crop up.  If that's true, then my concern obviously is that maybe things haven't healed, and these vitamin deficiencies are due to this lack of healing, even after so many years of the diet.

 

Can anyone shed some light on whether celiac-related vitamin deficiencies like this are typical, even for celiacs who have been on the gluten-free diet for years and who have, assumedly, fully healed?  Or am I just completely misinformed as to the way intestinal healing works for celiacs, even those who've been gluten-free for a while?

Well, from what I've read even folks who never had celiac can be deficient in these, especially as we get older. I am taking about 5,000 units of D3 a day and I have 1,000mcg B12 sublingual tablets that I take four times a day. That's a lot, but I have had no ill effects.

 

My Mom had undiagnosed celiac all her life and had to take monthly B12 shots. I think she had permanent damage. She wasn't diagnosed until she was in her mid-fifties.

I have been g.f. almost five years - faithfully so!   I am on s high dose of iron supps and b12.  I have tried to correct my levels with diet but the dr says this is one of the issues with celiac and I will prob always have this issue.  I did b12 shots for awhile which really helped "jump start" the levels and now seem ok with just supplements.  Guess it's just one of those little issues we have to put up with.

I have read that many people, not just Celiacs, are vitamin D deficient. B12 deficiency could be from the Celiac - it is the one thing that can linger. I don't have time to look this stuff up for the link right now. Google vitamin D deficiencies and pernicious anemia from some reputable sites like Mayo or webmd.

I have been gluten-free for nearly 20 years. I am still vit D deficient. I wonder if that part of the intestines is less able to heal for some reason.

do you take any acid reducing drugs?  these will interfere with B12 absorbtion.  D is not a dietary element so much, we are designed to obtain that from the sun.  we supplement because either that is not working, or we don't get enough sun.  good luck.

If you live in a northern climate, you most likely will be deficient in Vitamin D, Celiac or not.  If you wear sunscreen all the time, you most likely will be deficient in Vitamin D.

It is also a fat soluable vitamin and people with Celiac can have trouble absorbing fats for life......I do.  It is much improved since going gluten-free but my body still does not like high fat meals...which no one needs to eat anyway....unless you are strictly eating good fats only.  As we age, the GI tract doesn't work as well as it did in our youth so all of these can combine to make obtaining good levels difficult.

 

Vitamin B12 absorption can be difficult in the absence of intrinsic factor in the stomach.  You might want to read up on that.  You may need injections for a while to get your levels up and then maintain that with vitamin supplements.  Vitamin deficiencies can be tough to change in older celiacs and they can be improved but it might take some work to find the way that works for you.

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.
