Members overwhelmingly confirmed that vitamin D deficiency appears very common among those with fibromyalgia, with many sharing they were severely deficient despite sun exposure and now take daily supplements or prescription-strength doses to restore levels. Several members also reported additional deficiencies in B12, iron, potassium, and vitamin C, with some receiving B12 injections or discovering genetic mutations affecting vitamin absorption. A recurring theme was that while correcting the deficiency is important for overall health and preventing serious complications like heart issues or muscle cramps, many found it did not significantly improve their fibromyalgia symptoms, though members encouraged each other to advocate for proper testing and treatment.
