Nutritional deficiency is common for those with gluten sensitivity… And vitamin B12 deficiency is one of the most common nutritional deficits for those with gluten sensitivity.  If you are gluten sensitive, it is important to ask your doctor to monitor your B12 levels on a regular basis, as gluten can damage the small intestine and create permanent damage to the cells that aid in vitamin B12 absorption.  Vitamin B12 deficiency is related to a host of health problems, many of which have overlapping symptoms with gluten exposure.

  • Fatigue

    What if I have high serum B12 but don’t take B12 supplements?
    I have all the sy.symptoms listed in your video. My doctor argues I do not have B12 deficiency, but I believe I do. I think I’m just not absorbing B12 due to a variety of health issues.

  2. Ivar Soyland says:

    I’m using a liquid B12 with methylcobalamin and adenocylcobalamim. Works good and simpel to take. Also some times taking other B-vitamins, C-vitamin + just now testing Lserine for the memory. How that will work ( if at all ) is yet to see.

  3. Mary June Gordon says:

    I have heard that you should not take only one of the B vitamins because you will become deficient in the others which can cause problems. What about B12? Does that apply?

    Hi Doctor Osborne, thank you so much for your generosity in sharing valuable information to the world. You are a great teacher. Thank you for your e-mail and for being a blessing. Looking forward always for your e-mails. God bless you and family.

    Thank you for showing us how B12 deficiencies can effect us. I’ve had many of these symptoms and currently my Dr has me on B12 and is treating me for Crohns

    Thank you so much for this information. I have a gluten sensitivity. SIBO. Immunity issues. Sinus infections. Brain fog. Headaches. Psoriasis. Thyroid problems. Milk allergy too. I didn’t not know about Vitamin B-12. Thanks for teaching me something new. I was prescribed antibiotics continuously for 36 years along with Flonase for a 36 year long sinus infection. I try to avoid milk and gluten now and eat healing foods. I am still working at a life with more vitality.
