Irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder affecting 10%-22% of adults. Its development is closely related to the gut microbiota, and the inflammatory and immune responses triggered by the gut microbiota can lead to IBS. Vitamin D (VD) effectively treats IBS with fewer side effects by improving gut microbiota, immune regulation, and anti-inflammatory effects. In the future, it is necessary to carry out epidemiological studies on the relationship between VD and IBS, clinical studies on the efficacy of supplementing VD to improve IBS, and animal studies on the mechanism of VD improving IBS. Therefore, this paper discussed the relationship between VD and IBS.

Importance: Many individuals with irritable bowel syndrome (IBS) have insufficient or deficient serum 25-hydroxyvitamin D [25(OH)D] status; however, it is not clear if improved vitamin D nutritional status through higher intake can improve symptom severity and quality of life.

Objective: This systematic review and meta-analysis aimed to identify if changes in vitamin D intake or status affect symptom severity and quality of life in adults with IBS.Data Sources: MEDLINE®, Cochrane Central Register of Controlled Trials, Global Health, EMBASE, and Web-of-Science databases were systematically searched for relevant articles to August 12, 2024, in the English language.Study Selection: Clinical trials, prospective observational studies, and Mendelian randomization (MR) analyses reporting the effect of vitamin D intake or status on IBS-related outcomes were included.Data Extraction and Synthesis: Article review and data extraction were conducted by 2 authors following the PRISMA guidelines. Random effects meta-analyses and the Nutrition Quality Evaluation Strengthening Tools to assess risk of bias were employed for randomized controlled trials.Main Outcome(s) and Measure(s): Primary outcomes included measures of serum 25(OH)D status, symptom severity, and quality of life.

Results: 12 studies from 15 articles were included (n = 7 RCTs; n = 3 single-arm interventions; n = 2 MR). Seven study populations had deficient (<20 ng/mL) and three had insufficient (21-29 ng/mL) baseline serum 25(OH)D status. RCTs measured changes in serum 25(OH)D after 6-26 wks with 3,000 IU daily to 50,000 IU bi-weekly vitamin D dosages. Meta-analyses of low risk-of-bias RCTs revealed increased 25(OH)D levels in groups treated with oral vitamin D compared to placebo (n = 5; Pooled mean difference [95% CI]: 20.33 [1[2.91, 27.74] ng/mL; I2 = 97.9%). Quality of life scores improved significantly in deficient populations (n = 3; 3.19 [2.14, 4.24]; I2 = 0.0%).
Non-significant decreased trends in IBS symptom severity were shown across populations (n = 6: -25.89 [-55.26, 3.48]; I2 = 92.8%).

Conclusion: Moderate level evidence indicate vitamin D supplementation may improve status in adults with IBS and quality of life in those with deficient status at baseline.

Overview Gut and vitamin D contains gut-friendly information

Gut-friendly, Sublingual, injection, topical, UV, sunshine

Getting Vitamin D into your body has the following chart

Getting Vitamin D into your body also has the following
If poorly functioning gut
Bio-D-Mulsion Forte – especially made for those with poorly functioning guts, or perhaps lacking gallbladder
Sublingual – goes directly into the bloodstream
Fat-soluble Vitamins go thru the slow lymph system
   you can make your own sublingual by dissolving Vitamin D in water or use nano form
Oil: 1 drop typically contains 400 IU, 1,000 IU, or 4,000 IU, typically not taste good
Topical – goes directly into the bloodstream. Put oil on your skin, Use Aloe vera cream with Vitamin D, or make your own
Vaginal – goes directly into the bloodstream. Prescription-only?
Bio-Tech might be usefulit is also water-soluble
Vitamin D sprayed inside cheeks (buccal spray) - several studies
    and, those people with malabsorption problems had a larger response to spray
Inject Vitamin D quarterly into muscle, into vein, or perhaps into body cavity if quickly needed
Nanoparticles could be used to increase vitamin D getting to the gut – Oct 2015
Poor guts need different forms of vitamin D has the following

VitaminDWiki - Vitamin D interactions with poor gut (Celiac, IBD, and Bariatric surgery) – several studies


VitaminDWiki – Overview Gut and vitamin D has

  • Gut problems result in reduced absorption of Vitamin D, Magnesium, etc.
  • Celiac disease has a strong genetic component.
    • Most, but not all, people with celiac disease have a gene variant.
    • An adequate level vitamin D seems to decrease the probability of getting celiac disease.
    • Celiac disease causes poor absorption of nutrients such as vitamin D.
    • Bringing the blood level of vitamin D back to normal in patients with celiac disease decreases symptoms.
    • The prevalence of celiac disease, not just its diagnosis, has increased 4X in the past 30 years, similar to the increase in Vitamin D deficiency.
  • Review in Nov 2013 found that Vitamin D helped
    Many intervention clinical trials with vitamin D for Gut problems (101 trials listed as of Sept 2019)
  • All items in category gut and vitamin D 208 items

Asked Chat-GPT to compare IBS with IBD

Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD) are both chronic conditions that affect the digestive system, but they are distinct in their underlying causes, symptoms, and treatments. Here’s a comparison:

Nature of the Condition:
IBS: It is a functional disorder, which means the symptoms are not associated with any visible signs of damage or disease in the digestive tract. It affects how the bowel functions.
IBD: It is an autoimmune disease that involves chronic inflammation of the digestive tract.
   There is visible inflammation and damage to the digestive tract.

Common Forms:
IBS: It doesn't have different forms but can be classified based on the predominant symptom
    (IBS-D for diarrhea predominant, IBS-C for constipation predominant, IBS-M for mixed).
IBD: Common forms are Crohn's disease and ulcerative colitis.

Symptoms:
IBS: Abdominal pain, bloating, gas, diarrhea, constipation, mucus in the stool. The pain is often relieved by a bowel movement.
IBD: Abdominal pain, cramping, diarrhea, weight loss, fatigue, reduced appetite, blood in the stool, joint pain, and fevers.

Cause:
IBS: The exact cause is not known but it is thought to be related to a combination of abnormal gastrointestinal tract movements, increased sensitivity to pain, and possibly an imbalance of gut bacteria.
IBD: It is believed to be caused by an abnormal immune response, where the immune system attacks the cells of the digestive tract. Genetics, environmental factors, and an imbalance of gut bacteria are also thought to play a role.

Diagnosis:
IBS: Usually diagnosed based on symptoms and exclusion of other diseases. There are no specific laboratory tests to diagnose IBS.
IBD: Can be diagnosed through blood tests, stool tests, endoscopy, and imaging studies which show inflammation and damage in the digestive tract.

Treatment:
IBS: Treatment focuses on relieving symptoms. This may include changes in diet, medications to treat diarrhea or constipation, and stress reduction.
IBD: Treatment aims to reduce inflammation. This often involves medications such as anti-inflammatory drugs, immune system suppressors, and sometimes surgery to remove damaged portions of the digestive tract.

Complications:
IBS: It generally doesn’t cause complications but can significantly impact quality of life.
IBD: Can lead to serious complications such as strictures, abscesses, malnutrition, and increased risk of colon cancer.

Prevalence:
IBS: Is more common compared to IBD.
IBD: Less common but tends to be more severe.
It's important to note that although they have similarities in symptoms, IBS and IBD are fundamentally different. Proper diagnosis and management are crucial for both conditions. Always consult a healthcare provider for advice and information regarding diagnosis and treatment.
