HOW TO GET MORE VITAMIN D FROM EVERYDAY FOODS

Dr. Helena Ruiz, PhD

From where I sit in the laboratory, looking at food means looking at a beautifully complex matrix of molecules, chemical bonds, and biological vehicles. When we talk about vitamin D, or calciferol, to be precise, we are dealing with a fascinating, fat-soluble compound that behaves more like a pro-hormone than a standard micronutrient. In food […]
