Vitamins while on Letrozole

Abby • Married💍 TTC baby #1 🤰🏼

Going to be switching to Letrozole in a few weeks. Doctor said vitam C,D, and Zinc were all important to get while taking this medication and will help the medication work. I’m already taking prenatals, should I take the other 3 vitamins on top of my prenatal (Vitafusion Prenatal)
