Choline contributes to the maintenance of normal liver function and our product provides a full 100mg per tablet. We have also included milk thistle as a standardised extract from mature seeds, with a guaranteed level of 80mg silymarin. Silymarin is the active principle from the fruit of Milk Thistle (Silybum marianum). Milk thistle is one of the most extensively studied herbs in use today, and is widely recommended by practitioners. To complete our formula, we have added the B vitamins which have many roles, including contributing to the release of energy from foods. Our convenient one-a-day formula is suitable for vegetarians and vegans, and is made in the UK to GMP standards.
