Silybum marianum (Milk Thistle) is an herb that has been used for thousands of years. The herb is a tall, stocky, plant that grows fruit, and is native to the Mediterranean.

2. What does it do and what scientific studies give evidence to support this?

The fruit of the plant contains flavonolignands. These are responsible for the benefits of milk thistle.

Milk thistle has been used almost exclusively to support excellent liver health. It is a very powerful antioxidant ², and as such helps to remove toxic elements from the body. When the liver is damaged by alcohol consumption, steroid usage, pollutants, or any other environmental factor, milk thistle helps support the liver's ability to generate new liver cells.

3. Who needs it and what are some symptoms of deficiency?

Everyone can benefit from supplementing with milk thistle.

Because of milk thistle's ability to support the liver's ability to generate new liver cells, current or former alcoholics may benefit from its use.  Milk thistle has been shown to support liver's ability to recover, and protect the liver from further damage resulting from alcohol abuse.

Athletes and bodybuilders may benefit from the use of milk thistle. Athletes and bodybuilders typically use many nutritional supplements at one time, in order to boost performance. The use of a number of supplements at one time may produce synergism that results in enormous stress being placed upon the liver.

After a cycle of anabolic steroids, pro-hormones, thermogenics, or any other supplement, athletes may find it helpful to allow the body to rest from supplementation, while taking milk thistle to promote liver health.

Cycling supplements in an on-again-off-again manner, while using milk thistle in between, will ensure liver health and successful performance.

4. How much should be taken? Are there any side effects?

Side effects resulting from overdose can include: nausea, stomach pain, vomiting, diarrhea and headaches. To avoid these complications it is recommended that label directions be followed at all times.
