Imerslund-Gräsbeck Syndrome

Overview

Vitamin B12 is the sole indexed supplement for Imerslund-Gräsbeck Syndrome (1 study; low effect size, very low evidence, very low trust, WA 32). This inherited condition impairs vitamin B12 absorption from food, leading to deficiency-related problems.

Treatment involves vitamin B12 injections: daily for ten days initially, then once monthly for life. These injections appear effective for managing the condition in available research. Although the study count is small, ratings are high across effect size, evidence, and trust. See the evidence review below.
