Supplements such as milk thistle, artichoke leaf, and dandelion root may help detox the liver, but there isn’t enough evidence to prove it. Making healthy lifestyle choices is a better way to improve your health.
Your liver is one of your largest and most important organs.
In addition to storing and releasing energy from foods, it acts as your body’s natural filter. Your liver catches the “gunk” in your blood, removing toxins and wastes from your system.
Given how important this organ is to your health, it’s no surprise that supplement manufacturers have jumped on the liver detox bandwagon.
Dozens of products with names like “Liver Guard,” “Liver Rescue,” and “Liver Detox” claim they can get your liver in top shape — and help you feel better in the process.
Do liver supplements work? And does the organ that detoxifies your body really need its own detox?
In reality, many of the claims on liver supplement bottles don’t stand up to the research. Although some studies have found benefits from certain supplement ingredients — like milk thistle and artichoke leaf — they were mainly in people with liver disease.
Whether these supplements can improve liver function in otherwise healthy people has yet to be proven.
Liver supplement labels claim their products will “detoxify,” “regenerate,” and “rescue” your liver.
They purport to undo the damaging effects of alcohol, fat, sugar, and all the other toxins your liver’s been forced to process over the years — or after a weekend binge.
Liver supplement websites claim their products:
- promote liver function and health
- protect liver cells from damage
- stimulate the growth of new liver cells
- detoxify the liver
- improve blood flow from the liver
Manufacturers of these natural remedies promise that their supplements will regenerate your liver and restore it to its peak function. They also claim their products will give you more energy, strengthen your immune system, help you lose weight, and even improve your mood.
Weighing in at about 3 pounds, the liver has a lot of important jobs.
Your liver eventually processes everything you eat. After your stomach and intestines finish digesting food, it travels through your bloodstream to your liver for filtering.
The liver breaks down fat to release energy. It produces a yellow-green substance called bile to help your body break down and absorb fat.
This organ is also involved in sugar metabolism. It pulls glucose from your blood and stores it in the form of glycogen. Anytime your blood sugar level dips, the liver releases glycogen to keep your levels steady.
When alcohol, medications, and other toxins make their way to your liver, they’re pulled from your blood. Then your liver either cleans up these substances, or removes them into your urine or stool.
Many of the liver supplements on the market contain a combination of three herbal ingredients:
Let’s break down each ingredient by the research.
Milk thistle has been used to treat liver disorders for more than 2,000 years. It’s the herbal ingredient
The active substance in milk thistle is silymarin, which is made up of several natural plant chemicals.
Many of the studies on silymarin have involved people with cirrhosis, hepatitis B, or hepatitis C.
Because this supplement can lower blood sugar levels, people with diabetes should check with their doctor before taking it.
In studies done in
Though dandelion has been used to treat liver ailments, the evidence of its benefits is
In addition to milk thistle, artichoke, and dandelion, liver supplements differentiate themselves by adding a blend of other ingredients. This can include things like:
- wild tam Mexican root
- yellow dock root extract
- hawthorn berry
- chanca piedra
Well-designed human studies showing that these herbs work are still lacking.
There isn’t enough evidence to confirm whether taking supplements will detoxify or protect your liver. Yet a few lifestyle choices have been shown to improve liver health.
Here are a few tips to keep your liver in optimal shape:
Limit the fat in your diet
Eating a diet heavy in fried foods, sweets, and fast foods leads to weight gain. Being obese or overweight increases the risk of nonalcoholic fatty liver disease.
Keeping your diet healthy will result in a leaner, healthier liver.
Stay away from toxins
The chemicals in some insecticides, cleaning products, and aerosols can damage your liver as it processes them. If you have to use these products, make sure the room is well-ventilated.
Don’t smoke. Smoking is harmful to the liver.
Use caution when drinking alcohol
Large quantities of beer, wine, or liquor damages liver cells and can lead to cirrhosis. Drink alcohol in moderation — no more than one to two glasses a day.
Avoid chronic use of drugs
Every drug you take has to be broken down and removed by your liver. Chronic use or misuse of drugs like steroids and inhalants can permanently damage this organ. Use of harmful or illicit drugs such as heroin can also damage the liver. They should be avoided.
Don’t mix alcohol and medication
Using alcohol and certain drugs together can worsen liver damage. Read the instructions carefully before you take any prescription medication. Avoid alcohol if the label says the combination is unsafe.
Liver supplements make a lot of big claims. So far, research doesn’t support most of those claims.
If you’re thinking about taking one of these products, check with your doctor first to make sure it’s safe for you.
