Members overwhelmingly confirmed that low vitamin D levels are common with fibromyalgia, with many sharing their experiences of levels so depleted that doctors prescribed high-dose supplementation ranging from 5,000 units daily to 50,000 units weekly or monthly. Several members offered practical strategies that helped raise their levels, including taking vitamin D3 with vitamin K for better absorption, using liquid supplements instead of pills, ensuring adequate sun exposure in warmer months, and understanding that calcium requires vitamin D to be properly absorbed. A recurring theme was the frustration of persistently low levels despite treatment, balanced by encouragement to keep trying different approaches and working closely with doctors to find what works best for each individual body.
