What are the effects of Vitamin C on the liver?


The liver is the largest solid organ in the human body, and it performs over 400 important functions. For example, it manufactures and secretes bile, which helps with the absorption of vitamins and fats, and it creates blood proteins, cholesterol and immune factors. It also acts as a detoxifying filter, protecting the body from toxins introduced through the consumption of alcohol and certain drugs.

In order to perform its essential responsibilities, the liver needs the support of certain nutrients, including Vitamin C. Vitamin C is a natural antioxidant that can protect against the harmful effects of free radicals that build up in the body. This benefit is particularly helpful to the liver, as it is constantly working to clear the body of harmful substances. To give the liver the support it needs, some health experts advocate consuming elevated doses of Vitamin C.

The body cannot make Vitamin C on its own, so it depends on diet and Vitamin C supplements to get what it needs. Vitamin C-rich foods include oranges and other citrus fruits, strawberries, red cabbage, cantaloupe, broccoli, Brussels sprouts, red and green peppers, kiwi and tomato juice. However, Vitamin C supplements can also help support a healthy liver.

Vitamin C is generally considered very safe at high doses, but exceeding 2,000mg per day may cause nausea and digestive upset in certain individuals. High doses may also interfere with some medications, including drugs used to treat diabetes, cancer and HIV. It is best to consult a physician before taking high doses of Vitamin C or any other nutrient.
