This week, Joe and Terry discuss liver health with two specialists. You may not have spent much time thinking about your liver. It is, however, an absolutely essential organ. When the liver is working properly, every part of the body gets the nutrients it needs and no parts are exposed to damaging toxins. These are among its superpowers. Find out why you should love your liver.

At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

Love Your Liver:

Nutrients don’t go directly from the intestines to the rest of the body. Instead, they pass through the liver first. There, this master organ breaks them down into compounds that can be recognized and utilized by individual tissues and cells. Moreover, if it finds nasty chemicals that shouldn’t be there, it utilizes its superpowers to transform them into less damaging compounds that can be more readily excreted.

You should also love your liver because it can store nutrients for unanticipated periods of fasting and hold off starvation. This was a tremendous benefit during earlier periods of human evolution. These days, we have less need for a hedge against starvation. In fact, when we overload our livers with alcohol or sugar, even its superpowers may not be adequate. The liver’s response to this kind of insult is fibrosis, a condition in which it stiffens and stores fat.

Liver Disease:

One of the liver’s superpowers is that it can regenerate itself so long as we remove the source of injury. That’s pretty remarkable! But what if we keep on eating ultra-processed foods (Nutrients, May 10, 2023) and drinking soda or alcohol? In that case, the liver continues to try to repair itself. That can change the architecture of the tiny blood vessels that run through the liver, raising the pressure within them and ultimately leading to serious complications. Fatty liver disease, correctly termed metabolic-associated steatohepatitis (MASH), is the first step; cirrhosis and ultimately liver failure might follow.

How Do You Know If Your Liver Is Healthy?

The liver is so effective at maintaining the body in balance that most people don’t develop symptoms of trouble until liver disease is quite advanced. As a result, the best way to keep tabs on liver health is through blood tests. Tests for the liver enzymes called ALT and AST are common and often used to assess liver health.

Agents That Can Help or Harm the Liver:

If you love your liver, consider drinking a cup or two of black coffee daily. This has been shown to help the liver fight inflammation and overcome early-stage liver fibrosis (Redox Biology, March 2025).

Another precaution to take: avoid excess acetaminophen. This is the pain-relieving ingredient in Tylenol and hundreds of other over-the-counter medications. Doctors consider it safe for occasional use at doses under 4,000 mg in a day. Chronic use might call for lower doses yet. Because it is so widespread, people may mistakenly take several different medicines containing acetaminophen (paracetamol in the rest of the world) and end up exceeding the maximum dose by accident. Liver experts like our guest Dr. Ahmad treat such emergencies with a medicine called N-acetylcysteine.

Other pain relievers, such as NSAIDs, are less likely than acetaminophen to damage the liver. Dangerous reactions to such drugs are unpredictable, however, which can make them harder to manage. Fluoroquinolone antibiotics such as Levaquin and corticosteroids like methylprednisolone also fall into this category. Oral antifungal drugs can also be very hard on the liver.

Herbs That Can Challenge the Liver:

Pharmaceuticals are not the only compounds that may test the liver’s detoxifying superpowers. Botanical medicines can also cause challenges. Dr. Ahmad has treated people whose liver injuries were caused by green tea extract, turmeric, kratom or ashwagandha. Most people taking such supplements are attempting to improve their health, so discovering that instead they have developed liver damage is a nasty surprise. If you love your liver, stick with drinking green tea and eating curry rather than taking pills with concentrated extracts.
