Pharmaceuticals or drugs are typically used after there is an actual health problem; it is called the "if-then" approach. In addition, drugs used either singularly or in combination have great potential for side effects and complications. Nutraceuticals are generally used to prevent disease, maintain health, and fix nutrient deficiencies that lent itself to symptoms and eventually disease.

Frequently, people will be able to reduce the amount of medication they are taking with the help of their health providers. Lastly, people will often note a significant increase in the sense of their wellbeing.
