» I have been using 160 mg standardized to 45% ,
I can see why you are not getting the results you want. I think you need SP that is standardized to at least 85% of fatty acids, not 45%. What you are using is almost 50% less potent.
Q: Why should I take a standardized saw palmetto extract? What is it?
A: When scientists study saw palmetto for its clinical use and its mechanism of action, they use the extract preparations that are standardized for the same active components. Only in this way, results from different studies can be comparable and consistent. As any herb is composed of thousands of chemicals, different ways of extraction may give dramatically different amounts of its active ingredients. When a saw palmetto extract is standardized you know it is the type of extract used in studies and contains the same amount of active ingredients. This means you can expect it to produce the same benefits shown in studies. A standardized saw palmetto extract is standardized to contain at least 85% of fatty acids and sterols.
Q: How can I tell if a saw palmetto product is standardized?
A: Saw palmetto sold on markets are in many different forms. Many of them are not standardized. Some of them are labelled stardardized but when you look at the supplement facts on the labels their active ingredients are in much lower amounts. To tell if a saw palmetto product is standardized, you just need to look at the label under supplement facts and see if you can find fatty acids and sterols at 85% or higher. If you can it is standardized. Otherwise it is not.
