Vitamins are natural substances found in living things such as plants. The body can not produce vitamins and must obtain them from food or supplements.
Minerals are also found in plants. Plants obtain their minerals from the soil who receives minerals from the water washing over the rocks. Vitamins need Minerals to do their job and minerals must also be obtained from food or supplements because they are not produced by our bodies.
Antioxidants are specific Vitamins or Minerals that protect body cells from the damaging effects of Free Radicals. Free Radicals can come from or are caused by smoking, ultraviolet rays, stress, exercise, etc and are considered to be the primary cause of aging and disease.
Supplements are Vitamins and Minerals that have been extracted from a plant or created in a laboratory and put into a form (liquid, capsule, tablet) that we can take for our body to ingest. We get Vitamins and Minerals from eating fruits, vegetables, grains, nuts, spices or when we take a vitamin/mineral supplement. Some vitamins are also obtained by eating meat since most animals eat plant food.
Living with chronic pain can deplete the body of nutrients just like stress can. I have found taking Nutricalm, Fibralgia, and Nerve Control or Nerve Eight help me with my chronic pain from RSD / CRPS. I feel I have more energy. Several other people who have taken these supplements have also found them helpful. You can learn more about them at my Nature’s Sunshine Website
