Vitamin D May Prevent Diabetes in People with Certain Genes
A new analysis of the D2d trial shows that a daily 4,000 IU vitamin D supplement reduces the risk of developing type 2 diabetes by 19 % in prediabetic adults who carry the AC or CC variants of the vitamin D receptor gene, while those with the AA variant see no benefit. The researchers examined genetic data from 2,098 participants and identified the ApaI polymorphism as the key modifier of response. These findings point to a personalized prevention strategy for the 115 million Americans living with prediabetes. Experts caution that the high dose exceeds current guidelines and further trials are needed.
Tirzepatide Significantly Reduces Cardiovascular Risk in High-Risk Patients
Two recent real‑world studies demonstrate that tirzepatide, a dual GIP/GLP‑1 receptor agonist, markedly lowers cardiovascular risk in high‑risk patients.
