Nutrient is any substance that provide nourishment to a living being such as humans and plants. While plants get their nutrients from soil, human beings can have it from various food. The common examples of nutrients include carbohydrates, proteins, fats, and minerals etc. All these nutrients are inevitable for the functioning and growth of body.
Solution, on the other hand, refers to homogeneous mixture where components are uniformly distributed. This solution is often a liquid formulation made up of two or more substances. In this way, the term nutrient solutions simply stands for all the liquid preparation which encase various nutrients. These nutrients solutions are available in different forms such as injection, IV nutrition therapy, oral suspension, syrups, and protein shakes.
