Vitamins Come from Living Things
Every vitamin is made by living cells — either our own, or in other species. Vitamin D is produced in our skin, for example, when sunlight strikes a precursor of cholesterol. A lemon tree makes vitamin C out of glucose. Making a vitamin is often an enormously baroque process. In some species, it takes 22 different proteins to craft a vitamin B12 molecule.
While a protein may be made up of thousands of atoms, a vitamin may be made up of just a few dozen. And yet, despite their small size, v...

People Who Take Supplements are Less Healthy
Antioxidation vs. oxidation has been billed as a contest between good and evil. The battle takes place in cellular organelles called mitochondria, where the body converts food to energy, a process that requires oxygen and so is called oxidation. One consequence of oxidation is the generation of electron scavengers called free radicals (evil). Free radicals can damage DNA, cell membranes, and the lining of arteries; not surprisingly, they've been linked to aging, cancer, and heart disease. To ... 1

Extended Families as Important as Minerals and Proteins
Yes, and Trout harped on the human need for extended families, and I still do, because it is so obvious that we, because we are human, need them as much as we need proteins and carbohydrates and fats and vitamins and essential minerals.Yes, and Trout harped on the human need for extended families, and I still do, because it is so obvious that we, because we are human, need them as much as we need proteins and carbohydrates and fats and vitamins and essential minerals.
