Milk thistle supplements come in different forms, and this product is specifically an unrefined seed oil, which is different from standardized herbal extracts of the plant. The VITATEKA capsules contain cold-pressed oil from the seeds of Silybum marianum (milk thistle). The primary components you get from this oil are its natural fatty acid profile, including linoleic acid (an omega-6), and vitamin E, a natural antioxidant. In contrast, many other milk thistle supplements focus on standardized extracts of silymarin, a complex of compounds found in the seeds. If you are looking for the specific benefits associated with the oil's fatty acids and vitamin E content for general nutritional support, this is the appropriate product. If your interest lies in the compounds typically associated with silymarin extracts, you would need to look for a different type of supplement. Always check the label to confirm the active ingredient list.
