When my friends have a health concern they call me. I've always been a vitamin taker. I also take digestive enzymes and antioxidants and supplements that help with the thyroid and adrenals for my time-zone changes.
I need protein from food rather than just protein supplements. I changed my diet.
It's better to get the nutrients for healthy skin from food not supplements. Salmon walnuts blueberries spinach... lots of my favorite foods happen to be amazing for skin too.
