Clinical studies have shown that milk thistle supports liver function by helping to protect it from naturally generated body toxins.Detoxification is just one of the 500 functions that the liver must perform, 24/7. The liver is like the body’s waste treatment plant. It breaks down unwanted substances (preservatives, food additives and alcohol, for example) or unneeded substances (such as old red blood cells) and detoxifies them for removal from the body or recycles them into something the body needs.When we demand too much from our liver, it can become overloaded and not function as well. Milk thistle has long been recognized as a plant that has beneficial, liver-supporting properties. The National Institutes of Health (NIH) and the United States National Library of Medicine have catalogued over 400 scientific studies of milk thistle extract and its active constituents.One per Day FormulationFeaturing Siliphos Milk Thistle Extract for Increased AbsorptionSupports a Healthy Liver This item can only be shipped to an address verifiable on public record.
