Liver Can Be Damaged by 'Overdose' of Health Supplements

In Vietnam, a growing concern surrounds the potential harm caused by the excessive consumption of vitamins and health supplements. Doctors are warning that what many believe to be harmless 'health boosters' can, in fact, place a significant burden on the liver, the body's primary filtration system.

The liver is the 'central filter' of the body, but it is carrying a heavy burden from the wave of widespread vitamin and functional food use.

Dr. Nguyen Huy Hoang of the Vietnam Underwater and Hyperbaric Medicine Association highlights that numerous individuals consume a cocktail of supplements daily – multivitamins in the morning, liver detoxifiers at noon, collagen in the afternoon, and sleep aids at night, often alongside weight-loss or muscle-gain products. Each product contains numerous active ingredients that the liver must process, leading to an overload of its enzyme systems, particularly Cytochrome P450 (CYP450).

Many people have the habit of 'loading' all kinds of pills every day: taking multivitamins in the morning, adding a 'liver detox' pill at noon, taking collagen in the afternoon, and sleep support pills at night, even using weight loss or muscle gain products.

This overload can cause interactions between different compounds, leading to the accumulation of toxic substances or the creation of harmful byproducts. The lack of transparency regarding ingredient dosages in many 'proprietary formula' supplements further complicates risk assessment. While not all supplements are equally dangerous, international studies have identified certain groups, especially fat-soluble vitamins (A, D, E, K), as being particularly implicated in severe liver damage, including cirrhosis and increased portal vein pressure. The insidious nature of this damage, often progressing silently until detected during health check-ups, underscores the need for greater public awareness and caution regarding supplement intake.

The liver's enzyme system, especially Cytochrome P450 (CYP450) – responsible for 'processing' foreign substances – becomes overloaded.
