Importance of Proper Milk Thistle Dosage

milk thistle dosage how much should I take

In a world where health, fitness, and bodybuilding are considered popular practices, so is supplementation.  As we’ve come to talk about fairly regularly, there are a large variety of health supplement regimens that athletes and fitness freaks use to ensure the best possible results during both workout and recovery phases of fitness.  As is the case with many medicinal treatments, supplements can occasionally have less than favorable side effects on our liver or kidneys.  Thankfully, there is an easy, all-natural counter measure that most athletes and body builders use to prevent unintentional consequences on these internal organs.  As with all of the supplements we advocate for, proper milk thistle dosage should be administered to ensure a healthy regimen without consequence.

The Long and Short of Milk Thistle Dosage

Milk thistle has been extensively researched and has repeatedly been found to protect the liver organ in humans [1].  It’s important to not misunderstand the information in the various different clinical trials and studies performed throughout recent history.  Milk thistle has not been found to have regenerative properties.  Proper milk thistle dosage, however, has been found to prevent negative effects of what are normal harmful foreign substances and oxidants.  In other words, if you’ve been stacking supplements that your liver needs to break down, any damage that may have done will not be fixed by any amount of milk thistle ingestion.  That said, whether you’re already stacking or considering stacking in the future, be sure to add some milk thistle to your supplementation regimens.

It should be noticed that these preventative benefits aren’t the only benefits your body will see from healthy milk thistle dosage.  As shown in the studies, milk thistle has been shown to exerted antiviral, anti-inflammatory, and antioxidant properties in people who may be battling hepatitis B and hepatitis C.  It may not rid humans of such a prognosis, but it tends to strengthen the liver, slowing the negative effects and buying doctors more time for thorough treatment [2].

Something that you may find super useful: Recovery clinics prescribe milk thistle to heavy alcoholics.  Since the protective properties boost liver function, it might be worth remembering for those few times a year that we go out with friends and have a little bit too much to drink.  An extra dose of milk thistle before abusing your body with heavy amounts of alcohol can help ensure that the combination of alcohol and your stacks won’t cause extra damage to your poor liver [3].

How Much Milk Thistle Should I Take?

For those of you that haven’t been using milk thistle in their supplementation plans, don’t worry too much.  The liver is inherently regenerative.  Heck, humans can donate a piece of their liver to other humans and it will grow into a fully functioning liver over time.  From here on though, you should consider taking the “standard” dosage from now on.  200 milligrams two times a day is what’s considered the ideal amount for the common stacker.  Milk thistle is plentiful so it’s inexpensive and typical tablets come in 200mg doses so taking one in the morning and one at night is gravy for most people.  Check out one of our past articles about Milk Thistle benefits if you want more information.
