Modern medicine shares this perspective with Donguibogam. The liver is an exceptionally busy organ that detoxifies and metabolizes countless substances every single day. Although supplements are classified under the name of health functional food, once ingested, they must undergo metabolism in the liver just like pharmaceutical drugs. Problems arise when there are simply too many of these supposedly beneficial substances.
The liver bears a significant burden when metabolizing fat-soluble vitamins such as vitamins A, D, E, and K, certain minerals like iron and copper, and specific herbal ingredients. For example, excessive intake of vitamin A can accumulate in the liver and cause toxic hepatitis, while excess iron supplements can elevate oxidative stress, leading to hepatocyte damage. Many people assume products labeled naturally derived are completely harmless, but natural origins do not guarantee safety. Certain herbal extracts are well recognized for causing hepatotoxicity.
When these nutrients and compounds reach the liver, various detoxification enzymes, including the cytochrome P450 enzyme system within hepatocytes, are mobilized to process them. Overusing supplements can overstimulate or deplete this enzyme system, allowing unprocessed intermediate metabolites to accumulate within hepatocytes and cause inflammation and cellular injury. This condition is known as drug-induced liver injury, and it can readily occur from health functional food and routine supplements.
This constantly imposes additional work on the liver of modern individuals, which is already strained by chronic stress, irregular meals, and alcohol consumption. Because early signs often manifest as vague complaints such as fatigue and indigestion, they are easy to overlook. As the condition worsens, however, it can progress to jaundice, abnormal liver function tests, and even acute liver failure.
When taking into account individual genetic traits, underlying conditions, and potential interactions with other medications, supplement use is never something to take lightly. A balanced diet and consistent lifestyle habits remain the foundation of health. Supplements are merely secondary aids intended to fill specific deficiencies, not universal remedies. Consulting a healthcare professional to identify only what your body truly needs is the wisest approach.
