You should use nutraceuticals when your diet does not give you all the nutrition needed for your situation. Different life events need varied nutritional support. For example, most people know that a pregnant woman needs to eat more. She needs to eat a special diet because she is in a special situation. Pregnancy is a state that requires better nutrition for a better outcome. We know that if a woman does not have enough folic acid, she is much more likely to have a baby with certain birth defects.
Too much of something can be as bad as not enough. A woman who eats too much sugar when she is pregnant can develop a kind of diabetes that will also make her baby sick at birth. This is called gestational diabetes. It increases the child's risk of being overweight. The child is also at greater risk of diabetes as an adult.
In the same way, many other situations require better nutrition for a better end result. If you are injured, you need more nutrition to give your body the raw materials it needs to rebuild your damaged tissues. If you are sick with an infection, you need extra dietary chemistry to help your immune system. Good nutrition helps the immune system fight the virus or bacteria that is making you sick. And if you are having an operation, you will have an injury that needs to be repaired.
Inflammation is part of chronic conditions like arthritis and degenerative disc disease. The inflammatory process can result in destructive, painful diseases. Inflammation is caused in part by poor nutrition. Correcting your nutritional intake can relieve it. Osteoporosis is a condition in which bone is weakened because of nutritional deficiency. Taking supplemental minerals and vitamins can help improve the strength of brittle bones.
Once a disease is started, it is very hard for most people to eat enough of the right foods and to digest them properly to help. It takes a special effort to get the extra nutrition needed to get over an illness. Dietary supplements are used like medicine in this case. They are used to get the needed doses of nutrition in the right amounts required for healing damaged tissue.
Surgery requires good nutrition for the best possible recovery. In a hospital there are many extra challenges to the immune system. There are unusual bacteria and viruses your body must protect itself from. There is the stress of being away from home. Having pain and surgical wounds to heal are also stressors.
Spine surgery requires a lot of blood building. Your nutrition is the source of all the chemistry you need to make new red blood cells. You will have an excited immune system with a lot of work to do to protect you and help you recover. You will need an extra supply of nutritional elements to help you replace the blood you lost during surgery.
