Even with the healthiest of diets, we sometimes fall short of fueling our body with essential minerals, vitamins and nutrients. For this, we often take help of supplements, to boost energy or even support weight loss goals. However, not all supplements are safe, and some can indeed damage your liver. Let's take a look at this worrying fact...

What are dietary supplements
Dietary supplements are something we take for vitamins, minerals, herbs, amino acids, and other substances. It is said that supplements come in handy if we are unable to reach our nutrient goals through just food. They come in forms like tablets, capsules, powders, and liquids. Common examples include vitamin D, calcium, green tea extract, turmeric, and bodybuilding supplements.


While many supplements are indeed helpful, some contain ingredients that may harm the liver, especially when taken in large amounts, or without consulting a doctor.


How can these damage the liver

The liver is an important organ responsible for filtering toxins, and processing nutrients. When overloaded, liver cells can become damaged, leading to liver inflammation, scarring, or in severe cases, liver failure, which is often irreversible.

How can supplements damage the liver

Toxic Ingredients: Some supplements contain compounds that are directly toxic to liver cells.

Unregulated: Unlike prescription drugs, supplements are not strictly regulated. This means that most of them are available OTC (over the counter), at your local pharmacy, without the need of a doctor's note.

Long term use: Taking large amounts or using supplements for a long time can put strain on the liver, that can eventually give way.

Multi-Ingredient Products: Supplements for weight loss or bodybuilding often contain ingredients that can damage the liver.
