Ascorbic Acid/vit C- Issues With Digesting It? Help!

Hello,

Does anyone get sort of symptomatic from taking powdered Vit C? I am using NOW brand pure powder, says it's free of gluten and all the other allergens, but I think I'm getting a kind of gluteny feeling in my small intestine from it. I only take about 1/2 teas a day, which it says is 3750% daily value. I really think I need some extra C right now but I think I read here somewhere that some people may have an issue with it. Any insight is greatly appreciated.

Vitamin C can cause d. I take it in a pill form and to find out my maximum dosage, I started with 1000mg, then I added one pill to that each day till I got d. Then I subtracted one pill so I was taking the maximum amount I could with no discomfort. I can take 2000 mg. per day in addition to the 300 mg. in my multiple ... some people can take more than that.

Is corn a problem for you? A lot of Vitamin C is derived from corn although I would think if it says no allergens it should be corn free. It might be worth checking out.

I had a funny conversation with someone at a health food store yesterday when I told her I was looking for Vitamin C without corn she assured me that a particular brand didn't have corn in it just corn starch. I pointed out that corn starch came from corn. :o

Thank you both. Rinne, corn IS a problem for me and it doesn't say it's corn-free. I guess I must call the company- maybe that will help explain. I'm having a very bad day today after trying to take my (glutensupposedlyfree) B vitamin and the plain C. I just keep stopping taking any supplements because it seems I end up with issues. But I do think I could use a bit of a vitamin boost, never mind calcium and magnesium which I haven't attempted yet! Today is the first day in a long while that I can see and feel my small intestine moving around, bloated and very comprehensive joint and tendon pain! Maybe I got some gluten. Where? Where? Where?.....

Vitamin C can cause bowel intollerance if your system isn't used to it.  Also different forms are easier on the gut.  I don't tollerate plain ascorbic acid very well but sodium ascorbate (buffered) doesn't seem to be causing gut discomfort for me.

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease. While it's fascinating to hear anecdotes from other coeliacs who can drink it without immediate issues, this is a risky exception rather than the rule. The core issue is that Guinness is brewed from barley, which contains gluten, and the standard brewing process does not remove the gluten protein to a level safe for coeliacs (below 20ppm). For someone like you who experiences dermatitis herpetiformis, the reaction is particularly significant. DH is triggered by gluten ingestion, even without immediate gastrointestinal symptoms. So, while you may not feel an instant stomach upset, drinking a gluten-containing beer like Guinness could very well provoke a flare-up of your skin condition days later. It would be a gamble with a potentially uncomfortable and long-lasting consequence. Fortunately, there are excellent, certified gluten-free stouts available now that can provide a safe and satisfying alternative without the risk.

      Interestingly, this thought occurred to me last night. I did find that there are studies investigating whether vitamin D deficiency can actually trigger celiac disease.  Source: National Institutes of Health https://pmc.ncbi.nlm.nih.gov/articles/PMC7231074/

      Before being diagnosed coeliac I used to love Guinness. Being made from barley it should be something a coeliac shouldn’t drink. But taking to another coeliac and they can drink it with no ill effects and have heard of others who can drink it too.  is this everyone’s experience?  Can I drink it?  I get dermatitis herpetiformis and don’t get instant reactions to gluten so can’t try it to see for myself.

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
