Best Milk Thistle

Milk thistle, also known by its botanical name Silybum marianum, is a powerful antioxidant and anti-inflammatory herb. It has been used for its natural medicinal properties for thousands of years with great success.

Keep reading to learn about the uses for milk thistle.

Health Benefits of Milk Thistle

Antioxidant Properties

Milk thistle contains an active ingredient called Silymarin. It’s made up of potent antioxidant compounds called flavonolignans (namely silibinin, silycristine, silydianin, quercetin and taxifolin) that give milk thistle its incredible benefits.

It’s been shown to improve antioxidant activity and boost levels of the body’s most important antioxidant, glutathione.

This is good news because we’re constantly being depleted of antioxidants by free radicals from poor diet, medications, stress, chemicals, environmental toxins, and pollution.

The antioxidant properties of milk thistle may reduce inflammation and lower the risk of chronic disease by naturally scavenging free radicals and reducing oxidative damage in the body.

Liver Support and Detoxification

Milk thistle is most commonly known for its ability to detoxify the body and support the liver.

The liver has a vital role in filtering the blood, breaking down toxins, digesting fat, manufacturing hormones and regulating glucose levels. If the liver isn’t functioning optimally, we can experience major health issues.

A 2017 review of 17 studies found that milk thistle’s active ingredient silymarin can lower liver enzymes ALT and AST, which are markers for liver disease.

This herb can protect the liver by strengthening its detoxifying ability and neutralizing free radicals that are produced during detoxification, thus minimizing their ability to do damage. It may also block toxins from binding to receptors on liver cell membranes.

Milk thistle may benefit liver conditions like:

  • Hepatitis
  • Jaundice
  • Fatty liver disease
  • Alcoholic liver disease

Promote Healthy Blood Sugar Levels

Some impressive research suggests milk thistle may help to manage insulin resistance and promote healthy blood sugar levels. This may be due to milk thistle’s antioxidant properties, as pancreatic damage from oxidative stress has been implicated in the development of diabetes.

A 2016 review of randomized control trials found that people with elevated blood sugar had significantly reduced fasting blood sugar and insulin levels when given milk thistle extract. There was also an improvement in HbA1c levels, a marker of long-term blood sugar control.

In 2018, another study found that supplementing with silymarin notably reduced fasting blood sugar and insulin levels and improved insulin sensitivity.

Breast Milk Production

If you’re a breastfeeding mother and feeling exhausted by the process, you may benefit from this supplement.

A 2008 study found that mothers who took silymarin, the active ingredient in milk thistle, produced 64% more milk compared to the placebo group.

The research is pretty limited, so check with your doctor before starting this supplement.

Additional Health Benefits of Milk Thistle

Some other potential benefits of milk thistle include:

  • Reducing acne
  • Lowering cholesterol
  • Improving kidney function
  • Preventing bone loss
  • Supporting mental health and reducing obsessive-compulsive disorder
  • Boosting immunity
