Most of the vitamins and minerals in the multivitamin formulas as well as Bone Structure formula are from the fresh farm ingredients or from food sources such as organic algae (calcium), lichen (vitamin D3), sunflower oil (vitamin E), natto (vitamin K2), Indian gooseberry (vitamin C), selenium (sprouted garlic), Dunaliella salina (beta carotene), kelp (iodine), marigold flowers (lutein), and tomatoes (lycopene). Our proprietary formula also utilizes activated forms of vitamins to ensure that meaningful levels of key nutrients are delivered in the bioactive whole-food formula.
