Advertiser Disclosure
Every day, millions of Americans are forced to deal with frustrating health problems like fatigue, digestive discomfort, and unwanted weight gain.
But these symptoms are often “warning signs” that come from a place you’d least expect…
Your liver.
This hardworking organ is surprisingly sensitive. After all, it’s your body’s filter and it has to do a lot of heavy lifting — especially in our modern world filled with all sorts of toxins.
Fortunately, a powerful herb called milk thistle can offer some major relief. In fact, people who regularly consume a quality milk thistle supplement often report more youthful energy, smoother digestion, and a trimmer waistline.
There’s just one problem, though… not all of these supplements are created equal.
That’s because many manufacturers use shoddy ingredients, improper dosages, or unnecessary additives. As you can imagine, the result lacks the health benefits you deserve.
So how do you find a quality milk thistle supplement?
Well, Smarter Reviews has compiled years of research on this exact topic. This quick guide reveals the surprising benefits of a quality milk thistle supplement, what to look for, what to avoid, and the Top 5 formulas on the market today.

A healthy liver contains less than 5% of fat which helps it to function properly. This ensures that you feel your best. Thankfully, certain nutrients called antioxidants can help cleanse and “detox” our body. Plus, milk thistle is incredibly rich in antioxidants that are known to support your liver.
A Quality Milk Thistle Supplement Can:
Help your liver filter out common toxins
Assist in the breakdown of fat
Promote healthy blood circulation
Increase your energy levels
Support easier weight management
Best of all, there are a number of compounds that can make milk thistle even stronger.
A Great Milk Thistle Supplement Contains:
Zinc
Look for at least 50 mg to help flush your system & keep fat in check.
Zinc works with milk thistle to help your liver filter any unhealthy "junk." 50 mg or more of zinc will ensure you're getting the maximum amount of this essential mineral for proper liver functioning as you age.
Selenium
Activates powerful antioxidants for additional support.
Selenium is a key component of an antioxidant called glutathione. While milk thistle and zinc help eliminate everyday liver toxins, glutathione blocks the “bad guys” out. These antioxidants together can provide unmatched energy, digestive, and metabolic support for maximum effectiveness.
N-Acetyl Cysteine (NAC)
Activates powerful antioxidants for additional support.
NAC helps reduce oxidative stress in the liver to keep your immune system, cells, and tissues in check. It’s also a basic building block of glutathione, which has been called “the mother of all antioxidants.” You can find it in a variety of meats, seafood, and turkey.
Beware: Cheap Fillers
Magnesium Stearate
Companies use this cheap filler to cut manufacturing costs. However, it adds no nutritional value and may even negatively affect your liver health in large doses.
Titanium Dioxide
This chemical is used in supplements as a coloring agent in the U.S., but it is actually banned by the European Union for use in foods. This controversial ingredient has lead some to avoid it altogether.
The BEST Supplements Also Include:
Clinically Studied Milk Thistle
Unfortunately, many of the milk thistle supplements on the market are too weak to provide the benefits you want. On the other hand, milk thistle manufacturers like Siliphos® have real results backed by intense clinical research.
Clinically Recommended Dosages
Ingredients like milk thistle require proper dosages for peak effectiveness. Our research indicates that 80 mg per serving leads to amazing improvements in your overall health and wellbeing.
Prioritize Quality
The liver is the one of the most vital organs in your whole body. Excellent liver support might cost you a little extra, but we strongly believe the wide-ranging health benefits are more than worth it.
Money-Back Guarantee
It’s always a good idea to invest in a liver health supplement that offers a 100% money-back guarantee. This shows the company's faith in its product. So, look for brands that allow you to try their formulas for 90-days risk-free.

Overall Grade
PROS
- Contains quality ingredients
- Contains milk thistle
CONS
- Limited refund policy only for unopened products
- Missing key ingredients
The Bottom Line
Landing at #3, Dose for your liver includes a group of quality ingredients, including milk thistle. The company ran a clinical study on its liver health formula which showed good results — although it only had 30 participants.
Unfortunately, its missing key ingredients like tocotrienol, selenium, and zinc.
Consumers should be wary though because Dose’s return policy is not ideal. First, they don’t say how long their guarantee is. Second, they have to approve your return by email. And worst of all, you can only get a refund for an unopened product.

CONS
- Mixed customer reviews
The Bottom Line
Coming in at number 4 on our list is Liver Cleanse by Gaia Herbs. This product supports healthy liver function, involving both detoxification and elimination.
However, this formula is still missing some key ingredients, such as zinc and selenium and other important minerals that help detox and repair your liver in the long term.

PROS
- Contains a potent form of milk thistle
CONS
- Lacks key ingredients like zinc
- No money-back guarantee
- Mixed customer reviews
The Bottom Line
Rounding off our list is Liver Support by Vital Nutrients. It’s formulated with lots of important nutrients and ingredients, such as Silybin, a potent form of milk thistle. But once again lacks some key components, such as zinc and tocotrienols, for it to be a truly top-notch liver support supplement.
It’s worth pointing out that some customers said they did not experience any of the desired results and were disappointed with the product.
Potential customers should also take into consideration that there is no money-back guarantee for Vital Nutrients products.
