Animal and lab studies only

How it’s made and used

  • How much gets eaten2

    Scientists worked out how much rosemary extract people likely eat from food, and say their estimate is probably too high.

  • Fat breakdown during digestion4

    In lab studies, rosemary extract slowed the breakdown of fats in cooked pork during simulated stomach digestion.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted.
