How does First Day create formulas and develop products that are safe?Updated 2 months ago

From start to finish, our experts in nutrition, formulation, and manufacturing are dedicated to building products that make every day better for your family. Our multivitamins are the result of investigating thousands of clinical studies to understand what we lack. Our mentors, Dr. Ed Giovannucci, MD, MPH, ScD and Dr. Lei Chen, MD, MHS, help guide First Day's mission to build a better future for families and advise on the latest in proactive health and nutrition.

 Our scientific team has high standards, so we’re working on creating the best formulation we can before we release them. To separate truth from fiction, our team of experts investigated thousands of clinical studies. That’s why we use the latest science and source the most absorbable ingredients from all around the world so your vitamins are actually working for you and your health. All our products are manufactured in a GMP-certified facility in the USA, using only the highest quality ingredients.
