Is Calcium Safe with Wegovy?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Supplement with 1000–1200 mg calcium daily in divided doses (citrate form preferred for those with low stomach acid). Combine with vitamin D3 to optimize absorption. Perform DEXA scan if weight loss exceeds 10% body weight.
Why this interaction occurs
Significant weight loss with Wegovy reduces mechanical loading on bone, accelerating bone mineral density loss. Caloric restriction limits dietary calcium intake. GLP-1-induced gastric hypomotility and reduced acid may impair calcium carbonate absorption. Calcium citrate is preferred as it does not require gastric acid for dissolution.
Evidence
Evidence level: strong.
