What Does The Liver Actually Do?

Your liver is one of the hardest-working organs in your body, performing over 500 vital functions to keep you healthy [1]. Here are the key roles it plays every day:

1 2 3 4 5 6 7
1

Processing nutrients

Converts nutrients from food into usable energy and essential compounds your body needs to function.

2

Metabolism of fats

Breaks down fats, produces cholesterol, and creates lipoproteins that transport fats throughout your body.

3

Breaking down alcohol

Filters and processes alcohol and other toxins to remove harmful substances from your bloodstream.

4

Processing medicines

Metabolizes medications and other substances so your body can use them safely and effectively.

5

Bile production

Produces bile to break down fats and absorb essential fat-soluble vitamins like A, D, E, and K.

6

Energy storage

Stores glucose as glycogen and releases it when your body needs energy between meals.

7

Blood protein production

Creates essential blood proteins including albumin for fluid balance and clotting factors for wound healing.

What Can Put Extra Strain on Your Liver?

The liver is highly resilient, but certain lifestyle and metabolic factors can increase the demands placed on it over time. Excessive alcohol intake, excess body weight, an unbalanced diet, physical inactivity and poor metabolic health can all affect liver health and, in some cases, contribute to a build-up of fat in the liver [2]. Understanding these factors is an important first step towards supporting normal liver function and long-term liver health.

Alcohol

The liver processes alcohol, and prolonged excessive consumption can contribute to fatty liver, inflammation, fibrosis and ultimately cirrhosis [3].

Being overweight / excess abdominal fat

A major risk factor for metabolic dysfunction-associated steatotic liver disease (MASLD).

Diet

Particularly overall excess energy intake and poor dietary patterns rather than claiming that one fatty meal 'damages your liver'.

Physical inactivity

Regular physical activity helps regulate metabolism, reduce fat accumulation, and improve liver enzyme levels.

Metabolic health
  • Type 2 diabetes is associated with increased MASLD risk
  • High blood pressure is associated with increased MASLD risk
  • High cholesterol is associated with increased MASLD risk

What is Fatty Liver?

Fatty liver, also known as steatosis, is a build-up of fat within liver cells [4] .This condition can develop for different reasons and progress through several stages.

1. MASLD

Metabolic dysfunction-associated steatotic liver disease, previously commonly called NAFLD (non-alcoholic fatty liver disease).

2. Alcohol-related fatty liver disease

Associated with excessive alcohol consumption.

The stages of liver disease

Fat accumulation
Inflammation
Fibrosis
Cirrhosis

Most people with MASLD are at the first stage, and lifestyle changes can reduce liver fat and help prevent progression.

Concerned about fatty liver?

Food supplements are not treatments for fatty liver disease. If you think you may have liver disease, speak to your GP. Lifestyle changes including maintaining a healthy weight, exercising regularly, eating a balanced diet and limiting alcohol remain central to managing your liver health.

Milk Thistle vs Choline: Which Is Better for Liver Support?

Milk thistle and choline are very different ingredients. Milk thistle is a botanical ingredient traditionally used in liver supplements, whereas choline is an essential nutrient with an authorised UK health claim for the maintenance of normal liver function. For this reason, rather than choosing solely between milk thistle or choline, some multi-ingredient liver supplements combine both.

Milk Thistle

  • Botanical name: Silybum marianum
  • Naturally contains a group of plant compounds known as silymarin
  • Traditionally used in liver support supplements
  • Available as whole herb or concentrated extracts
  • Clinical evidence for treating liver disease remains mixed and inconclusive

Choline

  • Essential nutrient required by the body
  • Contributes to the maintenance of normal liver function
  • Contributes to normal lipid (fat) metabolism
  • Found naturally in foods including eggs, fish, meat and some plant foods
  • Has authorised health claims relating to liver function and lipid metabolism

Single vs Multi-Ingredient Liver Support

When choosing a liver support supplement, one of the first decisions is whether to choose a single-ingredient or multi-ingredient formula. Neither is automatically better: single-ingredient supplements offer a more targeted approach, while multi-ingredient formulas combine complementary nutrients and botanicals in one product. The right choice depends on what you want to supplement, the doses provided, ingredient quality, convenience and cost per daily serving.

How to Choose the Best Liver Supplement?

Make an informed choice with these essential criteria
  • Ingredients With Recognised Benefits
    Prioritise formulas containing nutrients with established roles in normal body function. Choline is particularly relevant for liver support because it contributes to the maintenance of normal liver function and normal lipid metabolism.
  • Look Beyond Milk Thistle Alone
    Milk thistle is one of the best-known ingredients in liver supplements, but it does not need to be used in isolation. A broader formula can combine milk thistle with nutrients such as choline, alongside complementary botanical ingredients including artichoke, dandelion and turmeric.
  • Amount and Form of Each Ingredient
    More ingredients or a bigger milligram number do not automatically make a better liver supplement. Check the actual amount provided per daily serving, as well as the form of each ingredient. For botanical ingredients such as milk thistle, turmeric and artichoke, look for concentrated or standardised extracts where appropriate, as these can provide a more consistent amount of key plant compounds than simply using raw herb powder.
  • Consider a Multi-Ingredient Formula
    A comprehensive liver support supplement can combine complementary nutrients and botanicals in one convenient formula. Liver Pact combines choline and milk thistle with artichoke, dandelion root, turmeric, vitamin C, zinc and B vitamins, alongside other carefully selected ingredients.
  • Capsules vs Tablets
    The delivery format matters. Capsules can provide a practical way to accommodate powdered botanical extracts and nutrients within a multi-ingredient formula. Rather than choosing based on tablet or capsule format alone, compare the ingredient forms, amounts and recommended daily serving.

FAQs

There is no single “best” liver supplement for everyone. Look for a well-formulated product containing clearly stated amounts of relevant nutrients and botanical ingredients. Choline is particularly noteworthy because it contributes to the maintenance of normal liver function and normal lipid metabolism, while milk thistle (Silybum marianum) is one of the most commonly used botanical ingredients in liver support supplements.

Supplements should complement, rather than replace, a balanced diet, regular exercise, a healthy weight and sensible alcohol intake.

Milk thistle (Silybum marianum) contains a group of plant compounds collectively known as silymarin and has a long history of use in liver support supplements. However, clinical research into milk thistle for liver conditions has produced mixed results, and there is currently insufficient high-quality evidence to conclude that it can prevent or treat liver disease [7].

For this reason, milk thistle is best viewed as a botanical supplement ingredient rather than a treatment for liver problems.

Choline contributes to the maintenance of normal liver function and normal lipid metabolism [5][6]. It is an essential nutrient involved in several processes within the body, including the transport and metabolism of fats.

Choline can be obtained from foods including eggs, meat, fish, dairy products, beans and certain vegetables, as well as from food supplements.

For most healthy adults, milk thistle and choline can be found together in multi-ingredient food supplements. They have different roles: choline is an essential nutrient involved in normal liver function and lipid metabolism, while milk thistle is a botanical ingredient traditionally associated with liver support.

Always follow the recommended serving of your chosen supplement and check with a healthcare professional if you take medication or have an existing medical condition.

No supplement can simply “detox” or flush your liver. Your liver already processes and removes many waste products and substances from the body.

Rather than relying on a liver detox supplement after periods of overindulgence, focus on the fundamentals: a balanced diet, regular physical activity, maintaining a healthy weight and limiting alcohol. Liver support supplements should complement these habits rather than compensate for them.

Yes. The liver has a remarkable ability to repair and regenerate, particularly when the cause of damage is addressed early. However, repeated or long-term injury can cause inflammation and scarring (fibrosis), which may eventually progress to cirrhosis and become irreversible [8].

Supporting long-term liver health therefore matters even if you currently feel healthy.

Fatty liver occurs when excess fat builds up in the liver. One common form is metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD). It is commonly associated with factors such as excess weight, poor diet, physical inactivity and metabolic conditions [2].

Early-stage fatty liver may improve with appropriate lifestyle changes. Food supplements should not be used as a treatment for fatty liver disease; speak to your GP if you are concerned about your liver health.

There is no single food that “cleanses” the liver. A Mediterranean-style diet rich in vegetables, fruit, wholegrains, beans and pulses, nuts, seeds, fish and unsaturated fats is a sensible approach to supporting overall and liver health.

Limiting heavily processed foods, excess saturated fat and foods and drinks high in added sugars can also form part of a liver-friendly diet.

Many liver support supplements are designed for daily use, but this depends on the ingredients, dosage and individual using the product. Always follow the recommended daily serving on the label rather than assuming that taking more will provide greater benefits.

If you take medication, have liver disease or another medical condition, are pregnant or breastfeeding, seek professional advice before starting a new supplement.
