The Claim

Daily supplementation with 100 mg vitamin B1, 100 mg vitamin B6, 200 µg vitamin B12, and 250 mg magnesium for four weeks in adults with Crohn’s disease in remission is not associated with a statistically significant change in patient-reported disease activity as measured by the Simple Clinical Colitis Activity Index (SCDAI).

In plain English

In adults with Crohn’s disease who are in remission, taking a daily supplement of vitamin B1, vitamin B6, vitamin B12, and magnesium for four weeks does not result in a measurable change in self-reported disease activity.

See the scientific wording

In adults with Crohn’s disease in remission, daily supplementation with 100 mg vitamin B1, 100 mg vitamin B6, 200 µg vitamin B12, and 250 mg magnesium for four weeks shows no statistically significant improvement in patient-reported disease activity, as measured by the SCDAI (β = −3.93, p=0.301), suggesting this combination may not be effective for symptom management in this subgroup.

Why this might work

Vitamins B1, B6, and B12, along with magnesium, help cells produce more energy by supporting the mitochondria, which reduces tiredness. But in Crohn’s disease, the gut inflammation that causes symptoms like pain and diarrhea is not affected by this energy boost, so the symptoms don’t improve.

1 study

  1. Study: Effects of B vitamins and magnesium on fatigue, disease activity and quality of life in inflammatory bowel disease

    This study gave people with Crohn’s disease in remission a daily pill of B vitamins and magnesium for four weeks and found their symptoms like pain and diarrhea didn’t get better any more than if they’d taken a sugar pill. So, the supplement doesn’t seem to help with symptoms in this group.
