Physical fitness is defined as the ability to work competently and successfully, to enjoy relaxation, to feel well, to resist illness and to cope with crisis conditions (Oxford University, 2013). A healthy regimen is designed to improve and maintain the patient's health (Meriam-Webster, Incorporated, 2014).

They can be single or in any combination of ingredients such as extracts, vitamins, herbs, metabolites, minerals, etc. and are produced in many forms such as liquids, tablets, powders, capsules, etc. (US Food and Drug Administration, 2009 ).
