nonessential nutrient

biochemistry

Quick Summary

A nutrient is a substance an organism needs from its environment for growth and life. Nonessential nutrients are those that an organism can synthesize itself. Even if available in food, these nonessential nutrients are often used directly, saving the organism energy that would be needed for synthesis.12

Essential nutrients, however, cannot be synthesized internally and must be obtained from food. In some cases, gut microorganisms can produce essential nutrients for their host. Nutrients provide energy and the building blocks for an organism's structure and functions. For humans, essential nutrients include proteins, lipids, carbohydrates, vitamins, minerals, and water.34
