Milk Thisle
Milk thistle (Silybum marianum) is a flowering plant whose seeds contain silymarin, a group of antioxidant compounds that support liver health. It’s traditionally used to protect the liver from toxins, support regeneration of liver cells, and improve overall detox capacity.
Does it really work?
The evidence is mixed but generally positive. Milk thistle has been shown to protect the liver in people with toxin exposure or certain liver conditions, though results vary and many studies are small or not well-controlled. It has a long history of safe use, and the antioxidant and anti-inflammatory effects of silymarin are well-documented. Benefits tend to be more pronounced for people under liver stress rather than those with healthy liver function.
Can I get enough in real food?
No. Milk thistle isn’t something you get from your diet — it’s a specialized herbal extract. While the plant is edible, the beneficial compounds are concentrated in the seeds and aren’t found in common foods.
Do I need a supplement for everyday health?
No. A healthy liver can handle detoxification without milk thistle. However, it may provide extra protection for people under higher toxin loads (like alcohol use, medications processed by the liver, or environmental exposures). It’s a supportive tool, not a daily necessity.
