High supplemental Calcium intake (≥500 mg/day) is associated with a lower risk of type 2 diabetes, whereas dietary Calcium intake is not significantly associated after multivariate adjustment.

If you are a woman, taking a Calcium supplement providing at least 500 mg daily may be associated with a modestly lower risk of type 2 diabetes compared to not taking such supplements. However, simply eating Calcium-rich foods may not provide the same protective association in this study.

ModerateQualifiesMEDIUM confidence
When we examined the association between calcium intake from supplements only and incident diabetes, we observed an inverse association even after adjusting for all covariates... women who consumed ≥500 mg/day calcium from supplements compared with women who consumed <250 mg/day had an 18% lower risk of diabetes
