I have used Swanson products for 2 years now. Some supplements work for me, while others had no effect that I could measure. The lecithin tastes great in my morning oatmeal. My opinion, is that it has been a useful aid in lowering my bad choleterol and assisting with the maintenance of my blood glucose levels (I am diabetic). It, along with their Siliphos capsules (a more biavailable form of milk thistle) have been useful in the maintenance of my liver. It was inflammed and now my doctor wonders how the enzymes have returned so quickly to normal.
