Ensure calcium intake of 1000–1200 mg/day through diet and supplementation (calcium citrate preferred over carbonate as it does not require gastric acid for absorption). Combine with vitamin D3 for optimal absorption. Monitor bone mineral density with DEXA scan annually if on long-term therapy, especially postmenopausal women.
Why this interaction occurs
Rapid weight loss associated with GLP-1 therapy, while metabolically beneficial, is known to reduce bone mineral density through decreased mechanical loading on bones and potential hormonal shifts. Reduced gastric acid from delayed emptying impairs calcium carbonate absorption specifically. Inadequate dietary intake from caloric restriction further exacerbates negative calcium balance. Long-term deficiency increases osteoporosis and fracture risk.

Evidence level: moderate.
Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 146,406 reports mentioning Semaglutide, Liraglutide (Ozempic, Wegovy). This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Semaglutide, Liraglutide (Ozempic, Wegovy) + supplement combination on this page.
FAERS reports are voluntary and cannot prove that a drug caused an event. Do not use report counts to assess the safety of this specific drug-supplement pair.
