According to the National Institutes of Health, all living organisms, including humans, require essential nutrients for normal physiological function. For human nutrition, the primary building blocks that provide bulk energy are carbohydrates, proteins, and fats. At a more elemental level, these complex molecules are all derived from a common set of chemical elements, including the core components: carbon, hydrogen, and oxygen.

Scientists have determined that all living organisms on Earth share a surprisingly small set of just six core chemical elements. These elements—carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur (CHNOPS)—form the foundation of the complex biomolecules necessary for life, from the simplest bacteria to the most complex organisms.

Every single living organism on Earth, from the smallest bacterium to the largest whale, is composed primarily of just six essential elements: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, commonly remembered by the acronym CHNOPS. This foundational consistency is why the 6 essential elements are important for life's structure, metabolism, and genetic material.

Over 96% of the mass of living organisms is composed of just four elements: carbon, hydrogen, nitrogen, and oxygen. These elements, along with other essential macro elements and trace elements for life, are the fundamental building blocks and catalysts for all biological processes, playing indispensable roles in everything from building DNA to powering cellular energy.
