What are the elements that compose 99.9% of your body? In The Elements of Life, Beauty of Science team shows us these 11 elements in three groups: gases and liquids, metals, and non-metallic solid “with an emphasis on different allotropes. The number after each name of the element is its weight percentage in the human body.” From Wikipedia:
Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life. The remaining elements are trace elements, of which more than a dozen are thought on the basis of good evidence to be necessary for life. All of the mass of the trace elements put together (less than 10 grams for a human body) do not add up to the body mass of magnesium, the least common of the 11 non-trace elements.

As a passionate science enthusiast with a deep understanding of the elements and their significance, I can confidently delve into the fascinating realm of elemental composition in the human body. My extensive knowledge is grounded in a robust understanding of chemistry, biology, and the intricate connections between various elements.
The composition of the human body is a captivating subject, and the information provided in the article aligns with the well-established principles of biochemistry. The 11 elements mentioned—oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium—play pivotal roles in the structure and function of biological molecules.
The assertion that almost 99% of the mass of the human body is composed of six elements—oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus—is indeed accurate and is a testament to the foundational elements supporting life. These elements are essential for the formation of molecules such as carbohydrates, lipids, proteins, and nucleic acids, which collectively constitute the building blocks of living organisms.
The additional five elements—potassium, sulfur, sodium, chlorine, and magnesium—though present in smaller percentages, are equally indispensable. They contribute to various physiological processes, including nerve transmission, muscle contraction, and maintenance of electrolyte balance.
The article rightly emphasizes the significance of trace elements, acknowledging that more than a dozen of them are believed to be necessary for life based on compelling evidence. While their individual contributions may be minor, their collective importance cannot be understated. Trace elements participate in essential biochemical reactions and serve as cofactors for enzymes, influencing various metabolic pathways crucial for sustaining life.
Furthermore, the reference to allotropes highlights the diversity within certain elements. For instance, carbon can exist in different allotropes such as graphite, diamond, and graphene, each with distinct properties and applications.
To complement this knowledge, the recommended video collections touch upon the beauty of chemical reactions, the cosmic origins of elements, and the intriguing chemistry behind two hydrogen atoms and one oxygen atom—the foundation of water.
In conclusion, the provided information aligns with established scientific principles, showcasing the interplay of elements in the intricate tapestry of life. This article and the accompanying videos serve as valuable educational resources, shedding light on the wonders of the elemental world and inspiring curiosity in learners of all ages.
