Sorry, no actual experience of them however there is plenty of quality information on the internet.
But probably not what you want to hear:
The 2 conclusions from this Meta Analysis on Plant Sterols and Blood Glucose seem to contradict each other.

There are plenty of studies which conclude that Plant Sterols do lower LDL Cholesterol. The big BUT is:
they do this by fooling the body that they are animal sterols and thus our bodies don't need to produce as much of our own (animal) Cholesterol.
My question: - Is this a good thing?
Note that: Cholesterol is so important to human brain function that the brain makes it's own supply of cholesterol. Some people claim to have reversed a dementia diagnosis merely by coming off statins. Many others have claimed that statins gave them 'brain fog' including our own
@Resurgam.
In people with sitosterolemia, high plant sterol levels have been associated with increased risk of premature atherosclerosis. (Which they were probably taking the plant sterols to try to avoid). Although it is proven that plant stenols can help to reduce LDL Cholesterol, they 'may not reduce the risk of heart attack or stroke'.
So in my opinion- What use are the, unless you want to lower LDL for it's own sake!
