                                Recent research reveals that adequate vitamin D levels are inversely related to bile acid concentrations, suggesting a regulatory role rather than a stimulating one. This challenges the common assumption that fat-soluble vitamin D must actively increase bile production. So, does vitamin D increase bile production?
