Serum levels of GLP-1 were found to be significantly lower in elderly patients with bone fracture compared to healthy adults. In addition, a significant correlation was found between decreased vitamin D and GLP-1 levels.
- In another study involving 18,746 adults with T2D, GLP-1 users had a 49% higher risk for vitamin D deficiency than SGLT2 inhibitor users, a 32% higher risk for vitamin D deficiency than DPP-4 inhibitor users, and a 54% higher risk for lower ...
- GLP-1 medications like semaglutide raise vitamin D deficiency risk by 49%. Learn why, what symptoms to watch for, and how much D3 to take during treatment.

- In another study involving 18,746 adults with T2D, GLP-1 users had a 49% higher risk for vitamin D deficiency than SGLT2 inhibitor users, a 32% higher risk for vitamin D deficiency than DPP-4 inhibitor users, and a 54% higher risk for lower levels of ferritin (iron) than SGLT2 inhibitor users.
Conclusion: Serum levels of GLP-1 were found to be significantly lower in elderly patients with bone fracture compared to healthy adults. In addition, a significant correlation was found between decreased vitamin D and GLP-1 levels.

- There is no evidence supporting routine supplementation with Vitamin D3 and K2 for patients taking GLP-1 medications for type 2 diabetes. [@{"id":1,"title":"
- Here are the supplements we recommend considering alongside the prescription of GLP-1 agonist medications: ... Vitamin D deficiency has been associated with insulin resistance, a key characteristic of type 2 diabetes.

Recent research has uncovered interesting connections between vitamin D and glucagon-like peptide-1 (GLP-1) that suggest potential synergistic effects. A significant finding in the literature indicates a positive correlation between serum levels of vitamin D and GLP-1 5.
