How long does alli remain in my body?
Since the time it takes people to digest food varies, the active ingredient in alli can remain in your body for up to 48 to 72 hours, mainly because the time taken for food to pass through the digestive system varies from person to person. However, it only affects the fat absorption of meals that are eaten within a short time of taking the capsule. Only a very small amount of orlistat is absorbed into the bloodstream.
