Product Description
Endurance athletes pay close attention to circulation, from how quickly the heart rate settles after an interval to how the legs respond in the second hour of a ride. Petadolex focuses on one specific area of circulation that doesn't get much attention: the blood vessels in your brain.
Petadolex from Integrative Therapeutics is a standardized butterbur root extract for healthy blood vessel relaxation in the brain.
Relaxation in the brain blood vessels – Petadolex is a butterbur root extract made for this one purpose. Each softgel delivers a standardized amount of the plant's key compounds, so you get a consistent extract every time you take it.
An extract made with a patented method – The patented extraction method is designed to capture the valuable petasites compounds from the root while leaving out toxic levels of naturally occurring compounds such as pyrrolizidine alkaloids. That process is what separates Petadolex from a basic butterbur powder.
Standardized to petasins, the key plant compounds – The extract is standardized to contain petasins, including petasin and isopetasin. Standardizing to a named compound means each softgel is measured by what it contains and not only by how much root went in.
Butterbur (Petasites hybridus) is a perennial plant, and its root is the part used for this extract. Petasins are the plant compounds the extract is measured by. Pyrrolizidine alkaloids are naturally occurring plant compounds that can harm the liver, and the label states that Petadolex is free of harmful levels of them.
How to Use Petadolex
Dose: Adults take 1 softgel three times daily.
Note: Do not use Petadolex if you are pregnant, nursing, or have a liver disorder.
