4. Improves your immune system
Our immune system works by tackling the infections and foreign bodies in the blood that it has encountered before, effectively stopping them before they can do serious damage. The immune system learns about different invading bodies and prepares the body for the next attack–and milk thistle can help.
Milk thistle supplement helps boost immunity and, specifically, it can regulate an “overreaction” by the immune system which is basically an allergy. Allergic to dust mites, cats, or dogs? Milk thistle will aid your immune system in understanding that it is not an immediate threat and will stop some of the symptoms from occurring.
