The best Silymarin: Our Picks

Guide: Questions you should ask yourself before buying Silymarin

What is silymarin?

Silymarin - you are probably not familiar with the term. When you search for silymarin, you inevitably come across the term milk thistle. Milk thistle is a natural medicinal plant associated with improving the condition of liver disease.

However, it is not the milk thistle itself that produces these positive properties, but a mixture of active substances that is extracted from the dried fruits.

And this is where silymarin comes into play. Silymarin, as we have already told you, is a mixture of active ingredients. It consists of the four flavonolignans silibinin, isosilibinin, silychristin and silydianin. Silibinin is the main active ingredient here.

Silymarin is extracted from the fruits of the milk thistle. It is composed of four flavonolignans and is thus a mixture of active substances.

What does silymarin do?

The positive effect of silymarin relates particularly to our largest internal organ - the liver. The biologically most active form of the flavonolignan mixture is silibinin and thus the lead substance of the active ingredient silymarin.

Silymarin stabilises the cell membrane of the liver cells and stimulates the regenerative capacity of the hepatocytes, i.e. the liver cells. Put simply, silymarin ensures healthy and functional liver cells.

Silymarin not only protects your liver, but also supports it in cell regeneration and in the formation of new hepatocytes.

What diseases does silymarin help with?

Silymarin helps you against many liver diseases. Silymarin is also suitable for prevention. Liver diseases can also be caused by many different things. One is viruses.

Infection by a virus can lead to liver hepatitis. In some cases, the disease is chronic, depending on the pathogen. Hepatitis A, B and C in particular are triggered by a virus.

Disease Description
Hepatitis Hepatitis is subdivided into hepatitis A, B and C. Viruses are often the trigger. In general, hepatitis refers to an inflammation of the liver regardless of the cause.
Fatty liver Fatty liver can have various causes. It can be caused by alcohol, obesity, diabetes or viral hepatitis, among other things. Fat is deposited in the liver cells and a fatty liver develops.
Cirrhosis of the liver Cirrhosis of the liver is usually the final stage of a previous liver disease. Cirrhosis is irreversible and the liver can no longer work properly.
Liver cancer Liver cancer often goes undetected in the early stages because the cancer progresses without pain. Only later does pain in the right upper abdomen occur. Liver cancer often develops from cirrhosis of the liver.

Silymarin has been successful as an active ingredient in all of these diseases. If you suffer from one of these diseases, consult your doctor and discuss treatment with silymarin.

Below is a list of signs of liver disease so that you can assess if your liver is doing well. It is important that you know the signs, because direct pain signals are rarely sent by the liver. Here is the overview:

  • Fatigue
  • Concentration disorders
  • Itching
  • Loss of appetite
  • Weight changes
  • Feeling of pressure in the upper abdomen

These signs can indicate liver disease. However, other causes can also be behind it.

How much does silymarin cost?

The price of silymarin depends on many factors. Among other things, the price varies from manufacturer to manufacturer and from pack size to pack size. The price also depends on the dosage form you choose. As a rule, however, silymarin is affordable.

Drugstore products can be found as dietary supplements for as little as 5 euros. Pharmaceuticals are available in smaller quantities from 7 euros.

What alternatives are there to silymarin?

Since silymarin is used for liver diseases, it is advisable to ask your doctor about alternatives. After all, you should not take your health lightly. Here we can and will only give you tips on how to keep your liver healthy and prevent liver disease.

The first step to improving the condition of your liver is to change your lifestyle. Always make sure that you eat a healthy and balanced diet. This includes avoiding alcohol as much as possible, as alcohol affects the liver and can lead to fatty liver in the long term. Exercise is also essential for your health and your liver. In addition, a low-fat and sugar-free diet is the first choice.

There are foods that help your liver with its detoxification function. Grapefruit helps cleanse and regenerate the liver. Or garlic, which contributes to the optimal detox of your liver through its sulphur compounds.

Buying criteria: You can use these factors to compare and evaluate silymarin

In the following, we will show you which aspects you can use to decide between the many possible silymarin products. Here you will find the criteria that will help you choose the right silymarin product:

  • Package size
  • Additives
  • Vegan
  • Quality

In the next sections, we will explain to you what is important in the individual criteria.

Package size

The package size is one of the most important buying criteria after you have decided on your purchase of a silymarin product. To do this, you should think about your exact purchase intention, why you want to take silymarin.

If you are only planning a short therapy with silymarin, then smaller pack sizes are worthwhile for your intention. However, if you are aiming for a long-term therapy with silymarin, then it is advisable to buy a larger quantity of silymarin.


You will not only find products on the market that consist of 100 percent silymarin. In most cases, there are other additives in addition to the active ingredient.

If you suffer from allergies or intolerances, such as celiac disease or lactose intolerance, you should pay special attention to the other ingredients. There are also preparations that contain artichoke or turmeric in addition to silymarin, which have their own benefits and can be combined with silymarin.


If you follow a vegan diet or a vegan lifestyle in general, you should make sure that the capsules are not made from animal products such as gelatine. This is often the case. You should also read the ingredients of the product carefully to make sure that it meets vegan standards.

When buying a dietary supplement, it is very important to pay attention to the quality of the product, especially when buying from an online platform. Many online retailers try to acquire sales figures with fake quality seals.

Inferior quality can cause far-reaching damage to health. Therefore, always play it safe and seek advice from a doctor or pharmacist.
