Vitamin D is very important during pregnancy. The DV 60K tablet contains cholecalciferol (Vitamin D3). While correcting a low vitamin D level is beneficial, high weekly doses like 60,000 IU should be taken during early pregnancy only under the direct supervision of her obstetrician. Often, doctors may prefer daily lower-dose supplements instead. I gently recommend having a quick chat with her OB-GYN to confirm if this specific weekly high dose is best for her individual needs.
