The Claim

In adults with inflammatory bowel disease in remission, daily supplementation with 100 mg vitamin B1, 100 mg vitamin B6, 200 µg vitamin B12, and 250 mg magnesium reduces fatigue and disease activity in ulcerative colitis but has no effect on fatigue and disease activity in Crohn’s disease.

Cause and effect
1 study reviewed
In plain English

In adults with inflammatory bowel disease in remission, a specific combination of B vitamins and magnesium reduces fatigue and disease activity in those with ulcerative colitis but does not affect these outcomes in those with Crohn’s disease.

See the scientific wording

In adults with inflammatory bowel disease in remission, the effects of daily supplementation with 100 mg vitamin B1, 100 mg vitamin B6, 200 µg vitamin B12, and 250 mg magnesium on fatigue and disease activity are specific to ulcerative colitis and not observed in Crohn’s disease, suggesting disease-specific biological responses to micronutrient intervention.

Why this might work

In ulcerative colitis, taking these vitamins and magnesium boosts energy production in cells and calms down inflammation in the gut, which reduces tiredness and symptoms. This does not happen in Crohn’s disease because the gut environment there does not respond the same way.

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

    This study found that taking these B vitamins and magnesium helped reduce fatigue and symptoms in people with ulcerative colitis, but didn’t help those with Crohn’s disease—even though both groups had the same condition in remission. So, the treatment works for one type of bowel disease but not the other.
