The kidney serves to […]

Multivitamins and Moving Toward Personalized Nutrition

Are multivitamin/mineral supplements beneficial? How do they relate to personalized nutrition? What even is a multivitamin? These questions were discussed at the “Multivitamin/Mineral Supplements in the Age of Personalized Nutrition” session Sunday during ASN’s Scientific Sessions and Annual Meeting. The chair of the session, Jeffrey Blumberg, PhD, introduced the session by noting that we don’t […]

How Nutrition Science Should Mature
