According to a 2023 review, the human body's antioxidant defenses rely on a complex interplay between internally produced (endogenous) and externally sourced (exogenous) compounds. This guide will delve into specific examples of endogenous and exogenous antioxidants and their crucial roles in maintaining cellular health and preventing oxidative damage.

According to scientific literature, inosine is a naturally occurring purine nucleoside found in all living cells, playing a central role in metabolic processes and genetic functions. It is synthesized within the human body and is also present in many common dietary sources.

A crucial fact about many vitamins is that the body cannot produce them internally, making them essential components of our diet. This raises the question: is vitamin E endogenous? The answer is no, humans and most animals cannot synthesize vitamin E and must obtain it from external sources.

According to the NHLBI, triglycerides are the most common type of fat in the body, primarily sourced from the foods we eat and stored for energy. This vital fat is also produced internally and plays a critical role in metabolic processes, but excess levels can pose serious health risks.

According to scientific consensus, the human body cannot produce the majority of the vitamins it needs to function properly, classifying them as essential nutrients obtained from external sources. So, are vitamins exogenous? The answer is a nuanced one, with most vitamins fitting this description while a few are synthesized internally under specific conditions.

According to the National Institutes of Health, xenobiotics are chemical substances that are foreign to an organism's normal biochemistry and can include drugs, pesticides, and some food additives. This foundational distinction helps answer the core question: are nutrients xenobiotics? The answer lies in their purpose, metabolism, and the body's expected physiological response to them.

Over 1.3 million deaths worldwide each year are caused by environmental pollutants, which are a major class of xenobiotics. A xenobiotic is any chemical substance found within an organism that is not normally produced or expected to be present, making naturally occurring endogenous compounds the answer to what is not a xenobiotic. This distinction is fundamental to toxicology, pharmacology, and environmental science.

The human body naturally synthesizes approximately 1 gram of creatine per day in the liver and kidneys, a process known as endogenous production. However, this isn't the only source, as exogenous creatine is obtained through diet and supplementation.
