Understanding Milk Thistle

In this issue, Solo Nutrition looks at… Understanding Milk Thistle 2300mg

Our poor livers have to work hard to detoxify everyday toxins and, as we know, over the festive season the liver’s burden increases. To a great extent our health is determined by the condition of our liver. So, it stands to reason that by optimising liver function, we can improve our health. Besides eating healthily, there are several supplements that can help to cleanse and protect the liver. Probably the most well-known compound used in liver support products is the herb milk thistle.

The Ancient Roots of Milk Thistle

The use of milk thistle (Silybum marianum) dates back to the 17th century, when it was quoted as a remedy for jaundice. In modern herbal medicine, the seeds of the plant are used to produce herbal extracts.

How Does Milk Thistle Work?

Milk thistle extract contains a substance called silymarin, which is responsible for the healing properties of the plant. Silymarin, a flavonoid compound, is made up of three parts: silibinin, silidianin, and silicristin ^[1]. Silibinin is the most active of the three constituents. Milk thistle extract works in several different ways. Being a flavonoid, it is a powerful antioxidant and is able to help prevent free radical damage from occurring. This is extremely useful, as the liver is continually exposed to these toxins. Milk thistle also protects liver cells by preventing the entry of harmful toxins and by helping to remove toxins from liver cells. Probably the most remarkable effect of milk thistle on the liver is its ability to increase the production of new liver cells and help regenerate damaged ones ^[2].

What Does the Research Say?

Livers that have been damaged from alcohol abuse have been shown to be regenerated with the aid of milk thistle, providing a person has stopped drinking. A comprehensive 2024 review in Cureus confirmed silymarin’s protective effects on the liver, showing promise in improving liver function and histological outcomes in various chronic liver conditions including chronic hepatitis, cirrhosis, and non-alcoholic fatty liver disease (NAFLD) ^[2].

In a double-blind study that involved 116 individuals with alcoholic liver cirrhosis, milk thistle produced a restorative action within two weeks. Other studies have shown that milk thistle is effective in treating many other liver diseases including chronic hepatitis (inflammation of the liver), fatty liver (excessive accumulation of fats in liver cells which is usually caused by liver damage), and bile duct inflammation.

A 2024 clinical trial published in Cureus evaluated 141 chronic liver disease patients and found that those receiving silymarin (200 mg twice daily) showed significant reductions in ALT and AST levels compared to standard treatment alone, with greater efficacy in metabolic conditions like NAFLD ^[3].

One study reviewed the effects of milk thistle on 2,637 people with various liver disorders (cirrhosis, fatty liver, and hepatitis). After eight weeks of supplementation, 63 per cent of the subjects said their symptoms had disappeared. Some of these symptoms included fatigue, lack of appetite, nausea, and abdominal bloating. On further analysis, 73 per cent of enlarged livers reduced in size. A 2024 meta-analysis of 26 randomized trials including 2,375 patients with NAFLD reported that milk thistle decreased fatty liver index levels, fatty liver scores, liver enzymes, and hepatic steatosis on liver histology ^[1].

More recent research has uncovered additional mechanisms. A 2025 study in the Journal of Pharmacology and Experimental Therapeutics found that silibinin (the main active compound in silymarin) helps maintain mitochondrial homeostasis in liver cells, reducing lipid accumulation and oxidative stress—key factors in the development of fatty liver disease ^[4].

Solo Nutrition’s Milk Thistle extract contains both seed and herb, and each capsule is equivalent to 2,300 mg of whole herb.

Dose: one capsule daily

Solo Nutrition’s Milk Thistle capsules are made with a high-quality botanical formula comprising a combination of both plant and seed for optimum effect.
