EThistle® Information for Healthcare Professionals

What is EThistle? EThistle® is the first supplement to combine milk thistle and vitamin E in one formula to promote a healthy liver. Recent research studies have observed the beneficial effects milk thistle and vitamin E have on liver wellness.

The EThistle® Formula


(from milk thistle seed extract)

360 mg daily

Milk thistle (silybum marianum) is an ancestor of the daisy family. Flavanoid complexes from milk thistle's seeds, fruit, and leaves are extracted for medicinal use. Historically, milk thistle has been used for liver, spleen and gallbladder health.

The liver keeps the body healthy and free of environmental toxins. Milk thistle's powerful antioxidant properties support normal liver function by blocking free radical oxygenation of fat and cell membranes.1

Vitamin E

400 IU daily

Vitamin E is a fat-soluble vitamin that also serves as a powerful antioxidant that protects your liver's function and overall health against the effect of free radicals.2
