Taking good care of your liver is one of the most important things you'll ever do for your health. The body's best filtration system, this mighty organ works day and night to help remove waste, toxins and anything else life throws your way. In addition, your liver works with the digestive tract to help the body process and utilize vital nutrients. For more than 2,000 years herbalists have used milk thistle and its key component, silymarin, to help support liver health. Part of the Vital Extracts herbal line, Solaray Milk Thistle provides 350 mg of milk thistle extract, guaranteed to contain 280 mg (80%) silymarin per one-capsule serving for a powerfully potent liver support supplement. Like all Solaray products, Vital Extracts Milk Thistle is lab verified for potency, purity, and identity.
