These Popular Supplements Might Cause Liver Damage, Study Finds—Are You Taking Any of Them?

TikTok is always ripe with the newest health craze, whether it’s taking hot girl walks or drinking raw milk. Another tip you may have heard creators rave about—that's also been used throughout history by people of various cultures—is consuming herbs or supplements. People may take them when they're in pain, feel bloated, are racked with anxiety, or need a boost of energy, for example.

At the same time, it’s important to note that supplements aren’t *always* safe, even if they have the “natural” label. Supplements aren’t FDA-approved before hitting stores, and they can cause harm if taken in excess. According to the Cleveland Clinic, too much of certain vitamins and supplements can increase the risk of osteoporosis, neuropathy and even death.

An August 2024 study in JAMA Network Open found that 5 percent of adults have taken one of the six supplements that are dangerous for the liver (the organ that filters out toxins and waste in the body).

Supplements That Damage the Liver

The supplements the study mentioned include:

• Ashwagandha, used to support the nervous and endocrine systems; improve sleep; and boost mood, energy and immune levels

• Black cohosh, used for pain, night sweats, menopausal symptoms and irritability

• Garcinia cambogia, used for weight loss, pain and digestive symptom relief

• Green tea extract (not green tea itself!), used for an energy boost, heart health and skin health

• Red yeast rice, used to lower cholesterol, improve blood circulation and promote digestion

• Turmeric or curcumin, used for inflammation, arthritis and anxiety

Liver damage can exist before symptoms show, and some people won’t have symptoms at all. The symptoms of liver disease that may appear, though, include nausea, lack of appetite, discomfort on the right upper corner of the abdomen, generalized itching, dark urine and yellow discoloration of the eyes and skin.

Alternatives to Those Supplements

If you’re tempted to take one of these supplements, consider other ways to get the nutrients or benefits they store. For example, some of the best foods for brain health include blueberries, avocados and nuts. If you need help falling asleep, a bowl of cherries or glass of milk might do the trick. Also, mindful breathing and exercise are natural energy boosters, believe it or not. These are other options that can help you meet those needs.
