Runica 300 has quietly become one of the most-searched supplements we stock — a 300mg milk thistle formula that people ask about in English and Spanish alike ("runica 300 para que sirve"). Here's a straight answer to what it is.
Milk thistle in one minute
Milk thistle (Silybum marianum) is a flowering plant whose seeds contain silymarin — a complex of flavonolignans (mainly silybin) that has been studied for decades, primarily around liver health and antioxidant activity. It's one of the world's most-used herbal supplements, traditionally taken to "support normal liver function".
What the evidence actually shows
Lab and animal studies show antioxidant and cell-protective effects. Human trials are more mixed: some show improvements in liver enzyme markers in specific groups; others show little difference from placebo. UK regulators allow milk thistle in traditional herbal registrations for digestive complaints — not as a treatment for liver disease. Honest bottom line: it's a well-tolerated traditional herb with promising but unproven benefits, not medicine.
How people take it
- Runica 300: one 300mg capsule daily with food is the label pattern.
- Standardisation matters — look for the silymarin percentage (typically 80%).
- Common companions in liver-support routines: artichoke, choline, dandelion — see our liver support collection.
Also popular here: the Uvora milk thistle range, which pairs the extract with complementary botanicals. Both ship with free UK delivery.
