Saw palmetto seems to be widely available in pharmacies and health food shops and is sold for a multitude of conditions.
Saw palmetto (Serenoa repens) is a fan palm which produces purple berries native to the West Indies and United States. It was used by native Americans to treat a variety of conditions but it is only relatively recently that the active ingredient that helps reduce hair loss and thinning has been identified.
Beta sitosterol is a phytosterol (plant sterol) found in saw palmetto and it is this that helps reduce hair loss. It achieves this by inhibiting the production of dihydrotestosterone (DHT). Increased DHT is known to kill hair follicles.
So, we know that saw palmetto contains a compound which can help reduce hair loss but only as a very small percentage. FolliMax from Medifort utilises pure beta sitosterol extracted from plant sources giving a considerably higher dose of beta sitosterol that is needed to act on DHT production.
Beta sitosterol also has other health benefits and is known to reduce cholesterol and improve cardiovascular health.
