Been using this for years. Helps with my cholesterol. The only thing I would Like to see is a marking on the pill to help distinguish from the others. Some are very similar and you do not want to over take the Endur Acin .

Phytosterols work

My husband and I have used phytosterols for many years and they certainly do the job. I'm disappointed that Endurance Products have discontinued the large 400 count bottle.
