With respect to the action those which can be equated from the Modern Pharmacology are Nourishing agents, Nutritional Supplements and Neutraceuticals. The Nutritional supplements are defined as those food products that are intended to provide nutrition that may otherwise consumed in sufficient quantities. They are those components that are not produced in the body nor are present in the food in a required quantity. These may include vitamins, minerals, proteins, etc. The same is a part of a larger group of supplements namely Neutraceuticals. The Neutraceuticals are defined as that category of substances that are used as a pharmaceutical alternative that claims to have a physiological benefit. Along with nutritional supplements it also houses the category of food additives too. here being a pharmaceutical alternative it can be used as a food or a medicine too. Thus it is technically defined as Nutraceuticals are products, which other than nutrition are also used as medicine. A nutraceutical product may be defined as a substance, which has physiological benefit or provides protection against chronic disease. The substances or formulations that are used to meet the nutritional requirements of the body are known. as Nutritional agents. These agents are usually considered when the oral intake fails to meet the requirements. They are of 5 categories namely Enteral agents, Parenteral agents Electrolyte replacements, Vitamins and Minerals. The enteral category are those where the agents are administered through the oral or nasogastric route (through Rylestubes). The Parenteral category are those where the agents are administered through peripheral or central veins. The Electrolyte replacements are those which are used to replace or supplement the body electrolytes and so is vitamins and minerals. Other than this even certain activities like Bulk Promoting action is also to be considered under this action. In this action, the increase with respect to the physical bulk through the increase of muscular or fat density is seen. Here the increase of muscular density is much preferred as they occupy less space and makes the body firm.
